He succeeded sooner than he expected, for he ran directly into a growth of raspberries, many of which were purplish black in color, soft, mild and delicious to the palate. He called to Victor and the two enjoyed a veritable feast. In the midst of it they were joined by Mul-tal-la and Deerfoot, who partook as bountifully as they. Later in the season they found an abundance of plums, wild apples and no end of mulberries. The journey continued for several days without special incident. When they reached the stream now known as the Great Horn they faced a serious problem. The current was rapid and deep, coursing violently between high ridges, some of which were so lofty that a regular cañon was formed. Mul-tal-la said they had come upon this river a considerable distance above the place where he and his companion forded it, and on the suggestion of Deerfoot he began searching for the ford or ferry, as it might prove. When nightfall came it had not been found, and the Blackfoot expressed doubts of his being able to locate it. This unexpected difficulty gave Whirlwind an opportunity to display his skill and intelligence. The party had paused at a place where the stream was a hundred feet or more in width, and with the current so roiled that there was no way, except by actual test, of ascertaining its depth. By hard work the horses might be able to swim or work their way across, but the necessity of taking care of the property on the back of Zigzag added to the difficulty. It was important that it should be protected from wetting. It would take a long time to build a raft on which to carry the stuff to the other side, and even then there would be risk of its being swept down stream. A dull roar that came to the ears of our friends through the solitude showed that there were falls or violent rapids at no great distance below, into which the raft would be likely to be driven with the loss or irreparable injury of much of the merchandise. Deerfoot was disposed at first to divide this among the four, who could hold the articles above their heads while their horses were swimming, but he distrusted the ability of the boys to do their part. The important thing was to learn the depth of the stream. He therefore asked Whirlwind to cross to the other rocky bank. If he could do this without swimming all difficulty was removed. The stallion was quick to understand the request made of him, though it is hardly to be supposed that he comprehended its full significance. When told to enter the stream he did so with only natural hesitation, feeling his way as his kind do when the ground in front is uncertain.
