In the former era the prism of the canal seemed imbedded with innumerable old and broken tow-lines, which the propeller, by its high velocity, sucked up, and was thereby "fouled;" and now the sea-grass is a hidden enemy that entwines itself around the propeller to foul it.
When the waters are low, forcing the engines of screw propellers lets the stern of the boat "squat" or hug the bottom, and although these are minor features of want of mechanical adaptation to canal duty, they illustrate petty detentions serving to lengthen the through times of steam.
Hence, if we intermix the slow steamers with the fast ones, as we do the slow with the fast horse-boats, for a general average, it is quite probable that horse-times are fully equal to those of steam, and that the excess of horse-cargoes makes a large and handsome advantage in their favor.
Therefore, under this general average, steam in 1872 is less economical than horses.
Conditional Explanations.
Because steam has been encouraged by the Legislature, heralded by the press, and favorably reported by the Executive officers of the State as a standard of advancement most desirable to attain, a supposition very generally prevails outside of canal men that it will succeed.
As early as 1845, before the enlargements, three steamers were built and tried, and one, the Pioneer, ran from New York to Oswego in five days, total time, 362 miles; and then "supposition very generally prevailed that steam would succeed." But light freights would not pay then as against full horse-freights; neither would they pay from 1858 to 1862; neither have they paid in 1872, as against horses.
A large part of the boats own and carry their horses, two teams (four horses), alternating the teams from boat to tow-path every six hours. Many desire to see the hardships, cruelties and dangers to horses obviated. It is said that one company during the war, when most of the best drivers turned soldiers, lost as many horses during the season as they put on for all their boats in the spring; that is, they had to purchase a complete equipment to make good their losses.
Some humane captains tow by the "lines" to avoid suffering and dangers to horses, many of which are drowned, and many left by the wayside. When changed from tow-path to stable, a stout man must hold the horse by the tail as he descends the steps into the stable, to prevent his pitching against the opposite side; and he holds with greater difficulty as he descends the bridge from the high, light boat to the tow-path, which is often more dangerous than the stable descent.
Others tow by the "lines"—take turns for teams, often with tedious delays—and they are, to a great extent, subservient to the drivers, else they suffer by their indifference, laziness or caprices, and many are sure to do their "poorest," unless they are feed extra.
