The question immediately arises, What sort of vehicle could weather such roads? First in the van came the great clumsy cart, having immensely high and solid wooden wheels. These were obtained either by taking a thin slice from the butt of the greatest log that could be found in good condition, or by being built piecemeal by rude carpenters. These great wheels would go safely wherever oxen could draw them, many of their hubs being three feet from the ground. Thus the body of the cart would clear any ordinary brook and river at any ford which horses or oxen could cross. No rocks could severely injure such a massy vehicle, at the rate it usually moved, and no mere rut could disturb its stolid dignity. Like the oxen attached to it, the pioneer cart went on its lumbering way despising everything but bogs, great tree boles and precipices. These creaking carts could proceed, therefore, nearly on the ancient bridle-path of the pack-horse age. On the greater routes westward the introduction of wheeled vehicles necessitated some changes; now and then the deep-worn passage-way was impassable, and detours were made which, at a later day, became the main course. Here, where the widened trail climbed a steeper "hog-back" than usual, the cart-drivers made a roundabout road which was used in dry weather. There, where the old trail wound about a marshy piece of ground in all weathers, the cart-drivers would push on in a straight line during dry seasons.
Thus the typical pioneer road even before the day of wagons was a many-track road and should most frequently be called a route--a word we have so frequently used in this series of monographs. Each of the few great historic roads was a route which could have been turned into a three, four, and five track course in very much the same way as railways become double-tracked by uniting a vast number of side-tracks. The most important reason for variation of routes was the wet and dry seasons; in the wet season advantage had to be taken of every practicable altitude. The Indian or foot traveler could easily gain the highest eminence at hand; the pack-horse could reach many but not all; the "travail" and cart could reach many, while the later wagon could climb only a few. In dry weather the low ground offered the easiest and quickest route. As a consequence every great route had what might almost be called its "wet" and "dry" roadways. In one of the early laws quoted we have seen that in wet or miry ground the roads should be laid out "six, eight, or ten rods [wide]," though elsewhere ten or twelve feet was considered a fair width for an early road. As a consequence, even before the day of wagons, the old routes of travel were often very wide, especially in wet places; in wet weather they were broader here than ever. But until the day of wagons the track-beds were not so frequently ruined. Of this it is now time to speak.
