What an immense aggregate of animal power was running to waste before us. Those huge shoulders, to which the whole body seemed simply a base, were just the things for neck-yokes. Others, indeed, had thought the same before us, and tried to utilize these wild oxen. A gentleman at Salina, Kansas, obtained two buffalo calves, and trained them carefully to the yoke. They pulled admirably, but their very strength proved a temptation to them. A pasture-fence was no obstacle in the way of their sweet will. Not that they went over it, but they simply walked through it, boards being crushed as readily as a willow thicket. In summer they took the shortest road to water, regardless of intervening obstructions, and they thought nothing of flinging themselves over a perpendicular bank, wagon and all. After carefully calculating the result of his experiment at the end of the first year, the owner decided that, although he undoubtedly had a large amount of power on hand, he could obtain a similar quantity, at less expense, by buying a couple of steam-engines. A few months previous to our trip, a contractor on the Kansas Pacific Railroad determined to domesticate a young bison bull, and accordingly took it to his home at Cincinnati. Proving a cross customer, he presented it to the Longview Lunatic Asylum, near that city, but there was no inmate insane enough to occupy the yard simultaneously with Taurus for any length of time. The first day he charged among the lunatics in a reckless manner, eliciting surprising activity of crazy legs. If exercise for their minds was what the poor creatures needed, they certainly obtained it, by calculating when and where to dodge. Without loss of time, we set about finding a gateway into the herds. Looking at the surface before us, it appeared a level, unbroken plain, quite to the verge where it rolled up against the distant horizon. One would have maintained that even a ditch, if there, might be traced in its meanderings across the smooth brown floor. Yet deep ravines, miles in length, wound in and out among the herds, though to us entirely invisible. A short search discovered one of these, which promised to answer our purpose, and to lead to a spot where a large number of cows and calves were feeding. Fortunately the wind was north, so that we could creep into its teeth without sending to the timid mothers any tell-tale taint. The wagons were stopped, and we got out, and descending into the hollow, moved forward. The walls on either side seemed disagreeably close. All around us was animal life, a small portion of which would have been sufficient, if so disposed, to make the concealed path which we were traversing a veritable "last ditch" to us. As we entered the ravine, some cayotes slunk out of it ahead of us, and one large gray wolf, with long gallop, disappeared over the banks. The temptation to fire at them was very strong, but prudence and the guide forbade.
