During seasons of high water, men, in traversing the plains, often encounter rivers which rise above a fording stage, and remain in that condition for many days, and to await the falling of the water might involve a great loss of time. If the traveler be alone, his only way is to swim his horse; but if he retains the seat on his saddle, his weight presses the animal down into the water, and cramps his movements very sensibly. It is a much better plan to attach a cord to the bridle-bit, and drive him into the stream; then, seizing his tail, allow him to tow you across. If he turns out of the course, or attempts to turn back, he can be checked with the cord, or by splashing water at his head. If the rider remains in the saddle, he should allow the horse to have a loose rein, and never pull upon it except when necessary to guide. If he wishes to steady himself, he can lay hold upon the mane.

In traveling with large parties, the following expedients for crossing rivers have been successfully resorted to within my own experience, and they are attended with no risk to life or property.

A rapid and deep stream, with high, abrupt, and soft banks, probably presents the most formidable array of unfavorable circumstances that can be found. Streams of this character are occasionally met with, and it is important to know how to cross them with the greatest promptitude and safety.

A train of wagons having arrived upon the bank of such a stream, first select the best point for the passage, where the banks upon both sides require the least excavation for a place of ingress and egress to and from the river. As I have before remarked, the place of entering the river should be above the coming-out place on the opposite bank, as the current will then assist in carrying wagons and animals across. A spot should be sought where the bed of the stream is firm at the place where the animals are to get out on the opposite bank. If, however, no such place can be found, brush and earth should be thrown in to make a foundation sufficient to support the animals, and to prevent them from bogging. After the place for crossing has been selected, it will be important to determine the breadth of the river between the points of ingress and egress, in order to show the length of rope necessary to reach across. A very simple practical method of doing this without instruments is found in the French "Manuel du Génie." It is as follows:

The line AB (the distance to be measured) is extended upon the bank to D, from which point, after having marked it, lay off equal distances, DC and Cd; produce BC to b, making CB=Cb; then extend the line db until it intersects the prolongation of the line through CA at a. The distance between ab is equal to AB, or the width of the crossing.

A man who is an expert swimmer then takes the end of a fishing-line or a small cord in his mouth, and carries it across, leaving the other end fixed upon the opposite bank, after which a lariat is attached to the cord, and one end of it pulled across and made fast to a tree; but if there is nothing convenient to which the lariat can be attached, an extra axle or coupling-pole can be pulled over by the man who has crossed, firmly planted in the ground, and the rope tied to it. The rope must be long enough to extend twice across the stream, so that one end may always be left on each shore. A very good substitute for a ferry-boat may be made with a wagon-bed by filling it with empty water-casks, stopped tight and secured in the wagon with ropes, with a cask lashed opposite the centre of each outside. It is then placed in the water bottom upward, and the rope that has been stretched across the stream attached to one end of it, while another rope is made fast to the other end, after which it is loaded, the shore-end loosened, and the men on the opposite bank pull it across to the landing, where it is discharged and returned for another load, and so on until all the baggage and men are passed over.

The wagons can be taken across by fastening them down to the axles, attaching a rope to the end of the tongue, and another to the rear of each to steady it and hold it from drifting below the landing. It is then pushed into the stream, and the men on the opposite bank pull it over. I have passed a large train of wagons in this way across a rapid stream fifteen feet deep without any difficulty. I took, at the same time, a six-pounder cannon, which was separated from its carriage, and ferried over upon the wagon-boat; after which the carriage was pulled over in the same way as described for the wagons.

There are not always a sufficient number of airtight water-casks to fill a wagon-bed, but a tentfly, paulin, or wagon-cover can generally be had. In this event, the wagon-bed may be placed in the centre of one of these, the cloth brought up around the ends and sides, and secured firmly with ropes tied around transversely, and another rope fastened lengthwise around under the rim. This holds the cloth in its place, and the wagon may then be placed in the water right side upward, and managed in the same manner as in the other case. If the cloth be made of cotton, it will soon swell so as to leak but very little, and answers a very good purpose.

Another method of ferrying streams is by means of what is called by the mountaineers a "bull-boat," the frame-work of which is made of willows bent into the shape of a short and wide skiff, with a flat bottom. Willows grow upon the banks of almost all the streams on the prairies, and can be bent into any shape desired. To make a boat with but one hide, a number of straight willows are cut about an inch in diameter, the ends sharpened and driven into the ground, forming a frame-work in the shape of a half egg-shell cut through the longitudinal axis. Where these rods cross they are firmly secured with strings. A stout rod is then heated and bent around the frame in such a position that the edges of the hide, when laid over it and drawn tight, will just reach it. This rod forms the gunwale, which is secured by strings to the ribs. Small rods are then wattled in so as to make it symmetrical and strong. After which the green or soaked hide is thrown over the edges, sewed to the gunwales, and left to dry. The rods are then cut off even with the gunwale, and the boat is ready for use.
