Dio was perfectly right, but the question was whether we could find the desired wood. From my knowledge of the country, I believed that no forest existed for many miles, the intermediate space being one extensive prairie, the very worst description of country to be caught in by a snow-storm. Still it would not do to pull up where we were, as we had no means of lighting a fire. We urged on our horses therefore, trying to keep as direct a course as possible. The snow, however, fell so thickly, that we could no longer discern objects at any distance. It was difficult, indeed, to steer a straight course, for the flakes quickly obliterated the tracks of our horses’ hoofs. We could only judge that we were going right by the wind, which blew on our left cheeks. That, however, veered about, coming in fitful gusts, and driving the snow against our eyes with a force that almost blinded us. Our horses, too, began to grow weary by their efforts to make their way through the snow, and I feared, after all, that we should have to dismount, and lead them on by the bridle. Still it would not do to give in.

“We must push forward, Dio, and perhaps the snow before long will cease,” I observed.

“Nebber fear, Massa Mike,” answered the faithful black whose teeth were chattering with the cold; “worse things dan dis happen ’fore now, and we got safe out of dem.”

I remembered, indeed, my many former providential escapes, and I had not forgotten that my dear little Lily was praying for us. Still matters looked worse and worse. The snow gave no sign of ceasing, while the wind blew more keenly and fiercely than before. The day, too, was drawing to a close. A night on the prairie under such circumstances would be truly dreadful. There was no moon, and with the sky obscured, should the snow continue to fall, we might even possibly become separated. I urged Dio to keep close to me, and I knew that Boxer would not fail to do so. We rode on and on, but our steeds went slower and slower, while the cold had become so intense that I feared we should be frozen if we continued to ride; I therefore, in the hopes of getting my blood into quicker circulation, by the exertion of walking, got off, as did Dio, and we led our horses. I went first, he following close behind me, and Boxer bringing up the rear. The snow had become so deep, that I had to lift up my feet at every step, making the exertion excessively fatiguing. Our horses went on readily enough. As I beat a path, Dio had somewhat less difficulty than I had. At last he begged that he might lead the way to relieve me, but this I would not allow. Severe as was the exercise, I still preferred it to riding. At last, our horses being somewhat rested, having brushed the snow from our saddles, we remounted and endeavoured to urge them on at a faster rate than we had lately been going. The snow suddenly ceased falling. I stood up in my stirrups to look round, in the hopes of distinguishing a wood in one direction or another where we might find shelter, but one uniform sheet of white covered the whole ground as far as the eye could see. Our great object was to keep in a straight line towards the east, but, as before, we had only the wind to guide us. Scarcely had we gone a hundred yards, when the snow again fell as thickly as ever. I felt the cold creeping over me. Poor Dio I knew must be suffering even more than I was, but not a word of complaint did he utter.

“Long lane, massa, dat hab no turnin’!” he cried out, trying to laugh. “Perhaps ’fore long we come to de wood where plenty of sticks, and we light fire, build hut, an’ de horses find grass, an’ we sit down warm and comfortable.”

“I shall be very thankful if we do,” I answered; “but it has become terribly dark. It will be a difficult matter to see a wood, even should we get near one.”

“Yes, Massa Mike, but de hosses find it out, even it we don’t,” answered Dio in a cheery tone; “what we best do is to let dem take dare own way; dey know what the wood is, dough we no see him.”

I followed Dio’s advice, but our horses showed no inclination to turn either to the right hand or to the left, but ploughed on through the snow, as though unwilling to remain exposed to it as we were; I took out my watch, but could scarcely see the hands, though I managed to make out that it was about five o’clock, and that the sun must have set; indeed, the rapidly increasing darkness assured me that in a short time night would overtake us. I soon could only barely distinguish the outline of my horse’s head against the white ground. I frequently spoke to Dio, for fear any accident should make him drop behind, when he might have a difficulty in finding me again.

“Do not lose sight of my horse’s tail, whatever you do,” I shouted out.

Dio promised to keep me in sight, but that was not so easy, though probably his horse would from instinct keep close behind mine. At last I could scarcely see my own hand when I held it up, and my horse’s ears were totally invisible. I had heard of travellers crossing the open prairie perishing in a snow-storm, and I began to fear that such might be our fate, but then I recollected Lily and my little sister. They were praying for us, and I took courage. Several times Dio and I got off to warm ourselves, but as I found on the whole that we made slower progress on foot than on horseback, we again remounted. I have since wondered how we could have endured the chilling breath of that piercing wind for so many hours. On and on we went, the time appeared longer indeed than it really was, but we had no means of calculating how it went by. Dio continued talking, both to assure me that he was close behind, and to keep up my spirits, though the idea of giving in as long as we and our horses had strength to move, never occurred to me. At length it seemed to me that my horse was verging to one side, as I felt the wind blowing in my teeth, more directly than it had hitherto done, then, after some time longer, a low murmuring sound reached my ears. It was, I fancied, the soughing of the wind among the branches of tall trees. Still I could see no object ahead. Next there came a lull, but the snow did not decrease. Presently I made out what seemed like a large column close to me, on the right hand side, then I saw another on the left. They were the trunks of trees, and from the irregular way the snow flakes fell, I was sure that we had gained the confines of the wood.
