Carrying such provisions as we might require on our backs, with a good store of ammunition and our rifles slung across our shoulders, we set out, Mr Tidey having a pocket compass by which we could direct our course. We hoped to reach the fort in two or three days at furthest, and we might do so sooner could we find water to refresh our steeds. Our own water-bottles contained but a small supply, but it was all that could be spared. My father charged us to keep a watchful look-out for Indians, and should we see any in the distance, either to hide ourselves or to trust to the fleetness of our steeds, rather than risk an encounter. Having bid farewell to my mother, Kathleen, Lily, and Dan, who was disappointed at not being allowed to accompany us, I joined Mr Tidey and Dio, and we pushed on ahead of the train. The heat was as great as on the previous day, but, as the Dominie observed, "We must not care for a slight inconvenience of that sort." I however twisted a white handkerchief round my hat, to keep off the rays of the sun, and he followed my example. Dio seemed very indifferent to them, his woolly pate protecting him better than all the artificial contrivances we could adopt. The only living creatures we saw were several deer passing in the far distance to the westward. Of course we could not venture out of our course to chase them. Neither streams nor water-holes could we discover, and we were obliged at length to encamp on the open prairie. Having tethered our horses a short distance from us, where they could crop the grass, wet with the dew of night, and having eaten our scanty supper, we lay down with our saddles for pillows, taking it by turns to keep watch. The stars shone brightly out overhead, enabling us to see a considerable way from our camp, but as I walked up and down during my watch, I could discern no objects besides our three horses, though I continually cast my eyes round the horizon. I occasionally heard the distant yelp of a pack of coyotes, though they were too far off to be perceived and did not come near enough otherwise to annoy us. I was thankful when Mr Tidey roused me up. Without waiting for daylight, as we could see our way without difficulty over the prairie and guide ourselves by the stars, having strapped on our packs and slung our rifles over our shoulders, we mounted and rode forward, our animals going much more briskly than they had done on the previous evening. When the sun rose the heat became as great as ever and the poor beasts began to slacken their speed, but eager to get on, we urged them forward with spur and rein until we began to fear that they would break down altogether. Suddenly, however, pricking up their ears and stretching out their necks, they broke into a gallop. "They smell water, though we can see no signs of it," observed Mr Tidey. "Yes! dare, dare some trees!" cried Dio.
