6. Notes on Certain Conversion Issues
The transportation infrastructure consists of the actual transportation network (roads, rivers, canals, rail tracks, pipelines), and the service facilities at the various nodes (stations, ports, etc.)
The first set of tables estimate the cost of constructing improved roads (table 1-1), railroads (table 1-2), and canals (table 1-3), based on historical data. My methodology is explained in more detail in a later section, but in essence I take the historical cost and deflate it, using an accepted consumer price index for London, to 1632.
It is important to recognize one of the limitations of this approach: it assumes that the cost of the various inputs (labor, materials, land, capital) in 1632 will have the same ratio to their costs in the source year (e.g., 1800), that the CPI for 1632 London did to that for London in the source year. If, say, iron is relatively more expensive in 1632 than the CPI implies, then railroads will be more expensive to build–unless, of course, there is some countervailing factor, such as labor or land being much less expensive.

Goods are transported over the transportation network by a variety of physical entities. These include
–pack animals carrying the goods in packs or panniers
–cargo vehicles mechanically propelled by an internal motive power (automobiles, steamships, airplanes)
–cargo vehicles propelled by an environmental force such as gravity, wind or water currents (sailing ships, barges floating downstream, mine cars rolling down an incline)
–cargo vehicles pushed or pulled by humans or draft animals (wagons, barges hauled by tow horses or rowed by crewmen)
–cargo vehicles pushed or pulled by other vehicles (boxcars pulled by a locomotive, barge flotillas pushed by a steam towboart)
The vehicles and service animals may be compared according to any of a number of criteria:
–operating cost (fuel for vehicles, food and lodging for the animals and crew)
–maximum carrying capacity (load)
–speed when carrying a particular load
–carrying efficiency (load per dollar)
–carrying efficiency (load per crewman)
Sailing ships have a high carrying efficiency (load per dollar and load per crewman) but also a high absolute price. Thus, characters in the 1632 novels are not likely to buy a ship unless they need to move ten tons or more in a single shipment.

Many animals can be used more effectively as draft animals; they can pull a heavier load than they can carry. The draft capacity basically depends on friction. In general, it is harder to slide an object than to roll it.
The next table describes the pull which different draft animals can generate. Some explanations will be helpful. Technically speaking, the weight of an object is not its mass, but rather the gravitational force which acts upon it. Force is mass times acceleration. Since the gravitational acceleration is virtually constant anywhere on the earth surface, if two objects are equal in mass, they are also equal in weight.
The table expresses the average weight of various draft animals in force units (kilo newtons). One newton is the force needed to give a kilogram mass the acceleration of one meter per second per second. Gravitational acceleration is about ten meters per second per second, so an animal with a weight of one kilonewton has a mass of 100 kilograms (about 220 pounds).
Multiplying the average weight by the pull-weight ratio, we get the average pull, which is the force the animal exerts on the load.
When a draft animal exercises a force causes a load to move, it does work. Work equals force times distance. Power is a measure of how quickly work is done, it is work divided by time. It can also be thought of as force times working speed, as in the table below. Power is measured in watts, which, technically, means newton-meters per second.
The energy output is the power output times the time, and is a measure of the work done by the animal. One kilowatt-hour means the energy produced or consumed by one kilowatt of power output over the course of one hour. One joule is the energy associated with one watt of power over the course of one second.

I have some more detailed information (Dale Wagner, “Loads”, on Draft Horse Chat Board.) on draft horses:
1200# horse can exert pull of 180# (15% BW) for ten hours, and can briefly pull 1800#.
1600# BW horse can exert pull of 200# (12.5% BW) for ten hours, and can briefly pull 2400# (150% BW).
2000# BW horse can exert pull of 220# (13.75%) for ten hours but can briefly pull 3000#. (good for starting a heavy load).
Note that the “Conestoga horse” had BW of 1600-1700#. (Shumway 137).
Another source (I unfortunately misplaced the note which identified it) said that a hose can pull 100-150#, avg. 120#, for 8-10 hours, at a working speed of 2.5 mph.
When an object is pressed into a surface as a result of the force of gravity, a frictional force is generated which opposes any attempt to slide or roll the object along the surface. That force is proportional to the component of the gravitational force (weight) which is perpendicular to the surface. To slide or roll a loaded vehicle, a draft animal must overcome the frictional force generated by the combined weight of the vehicle and its cargo. Generally speaking, less force is needed to cause a wheeled vehicle to roll than to cause an equally weighted sled to slide. Sliding friction is the result of surface asperities catching and releasing, while rolling friction arises from the deformation of the wheel and the road surface.
The ratio of the frictional force to the force pressing the object against the surface is called the coefficient of friction.
The coefficient of sliding friction is, as expected, much greater than the coefficient of rolling friction. Also, the force needed to start a stationary object sliding is greater than that needed to keep a sliding object moving, and so the “static” coefficient is greater than the “kinetic” one. For example, wood on wood reportedly has a static coefficient of 0.25-0.5, and a kinetic coefficient of 0.2. (Center for Advanced Friction Studies). The most relevant values for sledding are those for waxed wood on wet (0.14 static, 0.1 kinetic) and dry snow (0.04 kinetic)(Physlink.com).
If the motion is uphill, the necessary pull must overcome both the frictional force, and the component of the weight which is parallel to the surface, and thus is equal to
W (k cos theta + sin theta),
where W is the weight (in units of force), k is the relevant coefficient of friction, and theta is the angle of inclination.
On the other hand, if the motion is uphill, then the gravitational force is assisting the movement, and the necessary pull is
W (k cos theta – sin theta).
On a horizontal surface, sin theta is zero, and cos theta is one, so the pull needed is simply kW. The maximum load W which can be moved by a given pull is then 1/k.
There is actually surprisingly little published data on coefficients of rolling friction. Elert, “Rolling Resistance,” The Physics Hypertextbook, gives the following values for bicycle tires: on wooden track (0.001), on smooth concrete (0.002), on asphalt road (0.004), on rough but paved road (0.008). Allan at Colorado State says in “Vehicle Power Requirements” that a typical coefficient of rolling resistance for cars is 0.015. Urieli at Ohio University, in an article on scooter mechanics, gives a value of 0.01 for rubber tire on tarmac.
David Lawyer, in “Train vs. Auto Energy; Vehicle Resistance,” says that the rolling resistance is 0.01 for auto tires on roads, 0.007 for truck tires (higher pressure) on roads, and 0.001-0.002 for railroad steel wheels on steel rail. The rolling resistance is less for steel on steel than rubber on tarmac because rubber tires flex more and the deformation absorbs energy.
“Vehicle Motive Power, MTU13.HTM” gives the following values for average rolling resistance of rubber tires: on dirt roads (.028), on crushed gravel (.02), on flexible pavement (.013), on rigid pavement (.009), on ice (.015), on mud or on dry sand (.1), and on damp sand (.075). For snow, figure .04.
Some of the sources on overland transport do give a load-to-pull ratio for a particular wheel on a particular road surface.

The Historical Novelists’ Center (HNC) has published information concerning drafting ability for equines, relative to their body weight. The data on oxen is from Landels 177.
|Load on||Horse||Mule or Donkey||Oxen|
|wheeled vehicle; good road; walking pace||100%||120%||150%|
|car on rail track||1000%||1200%|
|barge on water||6500%||7800%|
This data has the following implications:
1) a mule or donkey is about 20% stronger than a horse of equal body weight, and that an ox is about 50% stronger. (The data is not consistent with that of table 2.2.1, which gives them equal pull-weight ratios);
2) the coefficient of friction between wheels and a “good road” is about ten times that between railroad car wheels and a rail track;
3) the coefficient of friction between wheels and a “good road” is about 65 times that between a barge and water (the latter is really a drag coefficient); and
4) the coefficient of friction between wheels and a “good road” is about half that between the sled and the surface contemplated.
Implication #4 makes sense only if the sled is on snow or ice.
It is interesting to note that an 80 pound sled dog can drag a 40 pound load on a travois. (sled dog manual) That is 50% of its body weight. Sled dogs are used mostly in arctic regions, so it is likely that the sled is on snow or ice.

In the seventeenth century, the employer was also usually responsible for feeding laborers; the workers did not pay for the food out of their own salaries. For travel on the employer’s business, the employer must pay for lodgings, too. Naturally, service animals also require feed and stabling.

All of the data I have seen on the cost of food for travelers has been for those staying at inns. That leaves open the issue of what the victualling costs for ship crews might be. I have used the official weekly ration for the Royal Navy in the early nineteenth century to estimate food consumption by ship crews, and then used a variety of sources to come up with a total cost for the standard ration. For the ration itself, see Dudley Pope, Life in Nelson’s Navy, 150-9.

Note that weights are not adjusted for the purser’s measure because we are calculating the provisioning costs, as opposed to the actual diet of the sailor. The sailor received 14 oz. pounds of bread and meat, 12 oz. pounds of butter, and 9 oz. pounds of cheese.
The beer served was “small beer”, i.e., not strong. Beer was replaced with wine in Mediterranean, and with rum or wine in the West Indies. The rum was watered down, 3 parts rum to one part water.
All in all, looks like about 60d a week, call it 9d a day per sailor.
I also have operating cost data which does not fit neatly into a particular category.

Mules are less temperamental and easier to train to carry a load than horses. Can withstand greater environmental extremes and survive on less food an water. Negotiates rough and steep ground better. (Landels 171-2).
Horses are more expensive, more finicky, and more vulnerable to disease and accident than mules, and hence they are more likely to be used as riding horses by the merchants and guards, than as pack animals. (HNC)
Oxen were less subject to disease, they were less likely to be stolen, and they made a good meal if food became more important than transportation. (HNC)
Camels could carry heavy loads further than horses or mules, and required little food and water while traveling. However, when horses encountered camels, they tended to stampede, disrupting wagon and pack trains. ((Huston 157).
Based on the data in section 2, we can reconstruct the cost of transporting your own goods. Even if you don’t want to do this, the analysis is worth conducting, because it acts as a “reality check” on the published cost of transporting by “common carrier”. To arrive at a do-it-yourself cost, we first need the acquisition (purchase or rental) costs of the vehicle (ship, wagon, etc.), service animals (horses, mules, etc.), and crew. Then we need to calculate the operating costs (food, lodging, tolls, etc.) for the route, which will of course be dependent on the length of the route and the speed which we can make upon it.
Riding Post. If you have a light but highly valuable cargo (jewels or legal documents, perhaps), and you are traveling on a major road, you may be able to “ride post,” changing horses every ten miles or so. The 1635 British rate was 2.5d/mile. If you carried ten pounds of cargo (remember, the horse is carrying the rider as well as the cargo, and for speed you want a light load), and made 100 miles a day, that would be an effective long ton mile rate of 560d (2.33 pounds sterling) a day!
In theory, a merchant, or group of merchants, could set up their own post system on any good road. Maintaining one horse at each of a series of inns ten miles apart would carry a cost of about two shillings a day per horse. You would need at least one extra horse, so a post boy could ride through, leading horses back to their home posts. Add another two shillings a day for the post boy. So a de minimis 100 mile post system would cost 24 shillings a day. The long ton mile rate, if it was used by just one courier a day, would be 54 shillings (2.7 pound sterling). For the private system to be cheaper than the British official post, it would have to be used by two couriers a day. But then a courier might be delayed because an earlier courier had taken the post horse to the next post and the post boy had not yet returned it. The solution is to have more horses per post, and more post boys. But that of course increases the system cost.
Since the Royal Post had a habit of seizing private horses when needed to speed a messenger along, some towns kept horses reserved for postal use. Leicester at one point kept six post horses at an annual cost of 33s4p apiece. Later it reduced the lot to four horses, ready at one hour’s notice, for an annual cost of 28s6d each. (Walker, 116) That implies a daily cost, covering horse rental, feed and lodging, of just 1d a horse (rather than the 2s assumed above).
Pack Mule and Pack Horse Trains. A typical long-distance mule train would have one wrangler for every six or seven mules (HNC). If each mule is carrying 300 pounds of freight, then there is about one short ton per wrangler. A mule train which is limiting its journey to a safe region might have twice as many mules per handler, yielding twice the “cargo efficiency”.
While it is possible to rent a horse or mule, that is usually for a jaunt in the local countryside, not for a long-distance journey. Let’s assume that we buy six animals at a price of thirty pounds each, reselling, after a year, at half price. That means that the effective rental price is fifteen pounds a year, or about one shilling a day, each. (Which is consistent with the local rental price.) Food and stabling for each animal is another shilling a day, and wages, food and lodging for the wrangler, another one to three shillings. So a pack train consisting of one wrangler with six packhorses would cost 13-15 shillings a day. If they made 20 miles per day, and each carried 300#, then the cost is 13-15 shillings transporting 0.9 tons 20 miles. The effective cost is then 6.5-8.1 pence per ton mile. But if they only progressed five miles a day, the cost would be 26-32 pence per short ton-mile.
The up-front cost of a minimal pack train is 180 pounds sterling for the animals, one month’s salary (1.5-4.5 pounds) for the wrangler, and expense money enough to cover them until the next major stop (where they could use a letter of credit). For safety’s sake, it is probably desirable to run a longer pack train, so there is more than one wrangler.
Wagon. Wagons are practical for long-distance traffic only where improved roads are available. A wagon with four horses and a driver might be rented for local work for 12.5 shillings a day, and I am going to assume that the amortized purchase price of the ensemble would be around the same number. Add another five shillings for their food and lodging, and, oh, round it up to 18 a day. The Conestoga wagon transports three short tons, and top speed is again twenty miles a day. So the rate per short ton mile is just 3.6 pence, about half that for the pack train. However, if the improved road is a turnpike, the tolls could wipe out the difference. Also, if the turnpike had a regulation limiting the load to just one ton (as England did in the mid-seventeenth century), then even without tolls, the ton mile rate for even a fast-moving wagon would jump to 10.8 pence.
River Barge. If it is just floating downstream, then you just need one man to steer it. If it is being towed by draft animals, then someone needs to be on the towpath, too. A typical crew was three men, even for a barge as large as sixty tons. (Willan 106, cp. Emerson 254).
Ocean-Going Ship. The cost of a ship should be roughly proportional to its surface area, since that will determine the amount of wood (or iron, in the nineteenth century) needed for the hull and deck. On the other hand, the cargo capacity of a ship should be roughly proportional to its volume. Nonetheless, comparative purchase cost figures are usually expressed as so many dollars per long ton. That ton is the displacement ton (35 cubic feet) for warships, and for merchant ships may be the register ton (100 cubic feet) or the actual cargo capacity (usually assumed to be 40 cubic feet per ton).
The next thing we need to consider is the operating cost. Sailing ships provided high cargo efficiency. Even the old cog could carry ten tons of cargo for each sailor. The epitome of the merchantman, the unarmed Dutch Flute (fluyt), had very efficient rigging, and as a result could carry fourteen tons for each crew member operating it. (Kohn I, [get page #]). The average Dutch ship of 1669 was one hundred tons, and had a crew of eight. (Braudel III, 190).
In Elizabethan times, British merchant sailors were paid almost twenty shillings a month (~8d a day), and were also fed at the shipowner’s expense. In 1700, the median common seamen’s monthly wage was 1.23 pounds sterling, or about 25 shillings.
Using British Royal Navy rations (Emerson 158, Pope 150-9), and a variety of sources to price them out, I arrive at a victualing cost of another 8d a day.
So the labor cost (wages plus provisions) is 16d a day, per sailor. If the ship carried ten tons of cargo per sailor, that is 1.6d per ton-day, and if the ship traveled sixty miles in the course of a day, 0.027d per ton mile.
However, this ignores the efficiency losses from waiting for cargo. For example, the Bristol to Bordeaux run, which was about 600 miles, and might take 10 days sailing time, was actually part of a 93 day round trip, when waiting time in Bordeaux was included. So multiply 1.6 by 93, and then divide by 1,200, to obtain its true ton mile labor cost of 0.124d. (If, while in port, half the crew is given shore leave at a time, and must pay for its own food, then cost is reduced to 0.1d.)
In the 1540s, the actual total freight charge in that wine trade, from a Bristol carrier, was about 0.33d per ton mile. In December, 1540, the Jesus of Torres charged only about 0.17d per ton mile.
Unless you are dealing in large quantities of bulk goods, the chances are that you will be hiring a common carrier — a railroad, barge, ship or wagoneer — to transport your goods for you. You will pay a price which will reflect both the intrinsic cost of carriage, and a profit to the carrier.
As explained in my article “Hither and Yon”, a standard method of expressing transportation costs is in the form of the rate per ton mile, which allows comparison of shipments of different tonnages and over different routes. One purpose of this FAQ is to explain how the cost per ton-mile data in that article were derived.
The raw data on costs takes the form, “in year 1XXX, it cost Y (in ducats, guilders, florins, thalers, pesos or whatever) to move goods G from point A to point B.”
If we know the cost for goods which traveled on different routes, then we can put them into the common unit, the cost per ton-mile, by dividing the cost by the number of tons, and the number of miles traveled. If we already have a cost per ton, then just dividing by the distance is enough.
By way of example, it has been reported that in 1807, the cost of road transport between Buffalo and New York City was $100 per ton (Anon. 1918). According to MapQuest, the road distance between these two cities is 400 miles, so that implies a unit cost of 25 cents per ton mile. The opening of the Erie Canal in 1825 reduced the freight charge to $15-25 per ton, and thus to a unit cost of 3.75-6.25 cents per ton-mile (Anon. 1918). By implication, shipment by inland waterway was 4-7 times cheaper than by roadway.
However, please note, when calculating distances, that the true routes are not as the crow flies, but rather must follow the prescribed paths, whether they be roads, canals, rivers or coastlines. The 400 mile route assumed by MapQuest uses roads which might not have existed in 1807. Riparian traffic is even less likely to be direct. For example, those using the Erie Canal first went east to Albany (291 miles), then south on the Hudson River to New York City (156 miles), a total of 447 miles instead of 400. That implies a unit cost of 3.3-5.5 cents per ton-mile, instead of the one previously calculated.
In the case of open water transport, it makes a big difference whether the ship hugs the coast (as was still common in the seventeenth century) or takes the most direct route. As pointed out earlier, maritime routes are often more roundabout than overland ones.
A more difficult problem is how do you find the 1632 equivalent of a cost incurred many years later? In section 5, I will explain how I manipulate data from other time periods. The method is far from perfect, but it allows one to generate plausible equivalents, which is really all that we can hope for.
Sometimes, the history books state the transportation cost as a percentage of the purchase cost. You can back-calculate the absolute transportation cost if you can find the purchase price somewhere; my research so far suggests that this is likely to be available only by checking primary sources. Alternatively, you can just figure out the percentage of purchase cost incurred per travel mile, but then the number can only be used in connection with the same type of goods. Because this data is harder to work with than the absolute costs, I have relegated it to an Appendix.
Here I present the mammoth tables of ton-mile data which I have assembled. In some cases, the ton-mile field is left blank because I have not determined the length of the route in miles. If a reader supplies that information (but bear in mind the warnings above), I can then fill in the ton-mile field.

Turner has published (on 1632.org) a very useful article on the European currencies of 1632. Turner only briefly touches upon the issue of changes in purchasing power with time. The buying power, in present money (year unstated), of one guilder in 1632 is said to be 24 modern British pounds (pre-Euro, I assume) or US$36 (implying that one 1632 shilling is NUS$18).
Using the IISG’s British inflation calculator, two English shillings in the year 1632 is equivalent to 10.49 pounds in the year 2000 (this calculation is based on the retail price index). During 2000, one British pound was roughly equivalent to US$1.50, implying that two 1632 shillings was equivalent to only about US$16 at the time of the Ring of Fire. The Grantville Gazette story “Other People’s Money” posits an exchange of one guilder to US$42, implying that the 1632 shilling is worth $21.
Likewise, according to the IISG’s Dutch inflation calculator, one Dutch guilder (florin) in 1632 is equivalent to 19.54 guilders (florins) in 2000. (Note that the rate of devaluation is different for English and Dutch currencies.) The average 2000 exchange rate into dollars was about 0.4, yielding an equivalent of only US$8.
Given the dominance of labor costs on costs of carriage, it arguably is best to use a wage index, especially one for unskilled laborers. The other approach is to use a consumer price index, which is essentially the cost of a “basket of goods”.
Allen, Robert, “Wages, Prices and Living Standards: The World – Historical Perspective”,
http://www.economics.ox.ac.uk/Members/robert.allen/WagesPrices.htm has published online spreadsheets (Excel files) setting forth the daily wages of building laborers and building craftsmen, with currency payments expressed as grams of silver, for Antwerp, Amsterdam, London, Oxford, Paris, Strasbourg, Florence, Milan, Naples, Valencia, Madrid, Augsburg, Leipzig, Vienna, Gdansk, Krakow, and Warsaw, beginning as early as 1264.
Both Excel files also include Allen’s Consumer Price Indexes for these cities. The methodology of computing the CPI is described in Allen, “The Great Divergence in European Wages and Prices from the Middle Ages to the First World War,”
My original inclination had been to use Allen’s laborer’s wage data. However, it is relatively spotty. For example, the same number is given for London for 1620-1639 (7.423871) and again for 1640-1649 (8.351855). Hence, I decided to use Allen’s CPI, which, being based on more than one “commodity”, is more responsive to year-to-year economic changes.
The following is a simplified British CPI, derived from Allen’s, which rounds the annual data to the nearest 1.5-fold change. (CPI for London in 1632 set at 100.)
1503-1518: 30 (except for 1512, CPI 44)
1522-1534: 30 (except for 1527, CPI 44)
1537-1544: 30 (except for 1541, CPI 44)
1557-1575: 44 (except for 1562, 1573; CPI 67)
1589-1593: 67 (except for 1591, CPI 44)
1650-1771: 100 (except for 1661, 1693, 1709, 1767; CPI 150)
1772-1778: 150 (except for 1776, CPI 100)
1790-1799: 150 (except for 1792, CPI 100)
1805-1820: 225 (except for 1815, CPI 150)
1821-1854: 150 (except for 1847, CPI 225)
The colonial American data, and even some early nineteenth century data, is expressed in English currency. I have assumed that there is a one-to-one relationship between the value of British shilling in America, and its value in Britain the same year. However, in fact it is likely that the British shillings traded here at a premium price.
Most of the ton-mile data that is readily available is for nineteenth century America. There are two considerations with the use of this data. First, for all post-colonial American figures, it is safe to assume that the ton is the U.S. short ton, 2000 pounds, not the British long ton, 2240 pounds.
Secondly, it will be necessary to convert the nineteenth century U.S. dollar to a 1632 equivalent. Plainly, there is no American consumer price index or dollar-pound exchange rate for 1632! Hence, we don’t have the choice of first deflating the 1800 dollar to its value in 1632, and then converting it at 1632 exchange rates to the British shilling (or Dutch guilder). Instead, I converted dollars to pounds using a contemporary exchange rate (EHS), then deflated the nineteenth century British amount using the Allen CPI for London.
The American/British exchange rate fluctuates daily. In 1999, one British pound bought anywhere from $1.56-1.66, depending on the purchase date. And the dollar and the pound are among the world’s more stable currencies. The EHS exchange rates are supposedly average values. Note that for the periods 1817-1861 and 1877-1918, the annual average was in the range of one U.S. dollar equals 0.20-0.22 British pounds. For 1866-1876, the equivalent was 0.15-0.18 British pounds. Over the longer period 1791-1918, the highest equivalent was 0.28 (1812), and the lowest 0.1 (1864).
Combining the EHS exchange rate data with the Allen CPI, we find that the equivalent of one U.S. dollar in 1632 British shillings is as follows:
There are, of course other European currencies, such as the Dutch guilder, which in theory could be deflated to 1632 using a Dutch CPI and then converted into British shillings, rather than converted first and then deflated.
In general, you cannot assume that if you convert currency A to currency B at the 1632 exchange rate, and then multiply by the year 2000 purchasing power of one unit of currency B, that you will get the same result as if you first multiplied the original amount of currency A by its year 2000 purchasing power, and then converted currency A to currency B at the 2000 exchange rate. The technical term for this is that there is a lack of purchasing power parity between the two currencies.
Units of weight: a British long ton is 2,240 pounds, an American short ton is 2,000 pounds, and a metric ton (tonne) is 1,000 kilograms or 2,204 pounds. There are 20 long hundred weights (each 112 pounds) in a long ton and 20 short hundred weights (each 100 pounds) in a short ton. Unless specifically stated otherwise by the reference, I assume that European data referring to tons and hundredweights means the long (British) form, and that American data means the short (American) form. Any reference to “tonne” is assumed to mean the metric ton. A “stone” is 14 pounds and a “quarter” (of a long hundred weight) is 28 pounds.
A short ton of sea water has a volume at 13oC. of 31.3 cu. ft. A long, or British ton – 2,240 pounds – of sea water occupies 35 cu. ft. The density of wine depends on its alcohol and sugar content. The specific gravity of sea water is around 1.035.

These are unedited raw notes which have not been integrated into the rest of the FAQ but are listed for what value they might have.
“Catalan records of shipping costs show that the cost of arming merchant ships increased freight rates by 25% or more between 1275 and 1330.” (Kohn I, p. 17; Kohn III, p. 22).
Cost of loading and unloading 50 tons, 1808, USA: $10.00 (Meyer 81)
50 ton canal boat required one man and 2 horses. (Meyer 81)
$60mil expended for transportation during War of 1812 (Meyer 91).
Cost of Passenger Train Operation, 1850s
Locomotive power, 20 cents/mile
Passenger car (60 seats), 2 cents/mile
Baggage car, 2 cents/mile
by implication, train goes 100 mpd
Can increase # of passenger cars to four without increase in locomotive power or baggage cars.
engine draws 100 tons
14 passengers with baggage (incl. Share of car) = 1 ton
4 cars, with 240 passengers = 17 tons
Passenger fare is 2.5.. 2.. 1 .. 1 cent/mile for 1-3 cars.
Cost of operation of horse railroad 1831
3.53 cents/ton mile
breakdown: mules and horses 1.33, hands, 1.33, repairing wagons 0.66, oil for wagons, 0.2. Ignores depreciation and replacement. (Meyer 588)
current on Miss. R carries boat 80-100 mpd.
Ohio R (high) 3-4 mph.
Can navigate at night on Ohio but not Miss.
State road from Charleston to Columbia SC failed because tolls too high, wagoners took free roads. (Meyer 258).
Cost to portage Louisville falls was 75 cents/ton. (Meyer 280)
RR. First flanged outer edge of rail, then inner edge of rail, then wheels. (Meyer 307) First horse railway, 1807, Beacon Hill (Meyer 308). Roads sometimes had sharp curves or steep grades to keep construction cost down. (Meyer 310). Solid granite track on Boston and Lowell had long life but destroyed rolling stock (Meyer 311). Strap iron rail on Ithaca and Oswego curled and pierced floors of cars. (Meyer 311). Building track on pilings instead of graded road bed was disastrous (Meyer 369).
Lockport and Niagzara Falls RR charges 25 cents/cwt normally, but only 15.5/cwt for carload lots. 24.3 miles. (Meyer 377)
Copper sheathing of ship bottoms began in 1761, improved speed by reducing barnacle drag factor. (Armstrong 41).
American ships at Canton averaged 297 tons (Armstrong 47).
Insurance for ships
1782 20% without convoy, 12% with. (Armstrong 55)
1806 8%, 1812 5.3% (under convoy system)(Armstrong 48)
1860 average tonnage, sailing ship 160 tons, steamship, 220 tons. (Armstrong 118).
Largest sailing ship, France II, 5633 tons, 1911. (Armstrong 121).
Madrid postmaster bribed 28 ducats a month to let Enlgish envoy see all letters from Englishmen. (Walker, 54).
England 1621 – four wheeled wagon had maximum weight by law of one ton. 1662 – maximum cargo of 20 cwt (one ton) in winter and 30 cwt in summer. (Albert 133).
For ships, size limit for wood ships was around 2000 tons. (Braudel SEL 423).
Water Travel: A quantum leap in carrying capacity was achieved when you left dry land. The maximum size of the river boat actually depends on the river conditions. On most British rivers, the barges were at most twenty to forty tons (Willan 97), but on the Thames, barges eventually reached a size of 250 tons (Sailing Barge Ass’n). On the Elbe-Lubeck canal, the standard size boat is 19 meters by 3.25 meters, and carries 12.5 tons. (Hadfield 33). The largest Russian barges were 150-170 tons (Hadfield 56).
Large ships were usually built, to order, for a group of merchants, each thereby acquiring a share in the ship. (Kohn I, p. 29).
The typical size of a sailing ship depended on circumstances. In the seventeenth century, the typical English ship trading to Spain was twenty to forty tons. (Kohn I, p. 25). [this seems small to me] Small ships could use smaller harbors, could find full cargoes faster, and could be loaded or unloaded quickly. For the long-distance trade to the Spice Islands, larger vessels, in the 500-1,000 ton range, were used.
