We are camped on the banks of the South Platte. The men have driven the stock across to an island. I do not know if it is because they are afraid of the Indians stampeding them, or that the grass is better. If there should be danger, I presume they would not tell us. There is a town of prairie dogs near; several of us went to make them a visit, but the boys had been there with their guns shooting at the little things, and frightened them so they would not come out, although we waited in silence until almost dark. I shall make another effort to see them very early in the morning before the boys are awake. I have heard they are early risers, that they come out to greet the rising sun. We met an acquaintance to-day--Will Musgrove--he is on his way to Central City, Colorado. He is night herder for a freight train. The most casual acquaintance seems like an especial friend, when we meet, away out here, so far from home, or anywhere else. PRAIRIE DOGS. Tuesday, June 20. Winthrop was quite sick last night with cramp colic. I was up with him the latter part of the night, so was dressed and ready for my visit to Prairie Dog Town at an early hour. The little fellows were up, standing at their doors, and greeted me with a welcoming bark. Some of them turned and darted away, no doubt to tell others we had come, for they immediately came back to peep out at us and bark and chatter, as if carrying on a lively discussion. They seemed perfectly fearless as long as we kept our distance, but if we tried to get a nearer view, they whisked away, and were gone in an instant; then they would send out two or three scouts, and if we had gone far enough away, they would come again to their doors. They have been well described by many writers. Cash and Frank joined me, while at Prairie Dog Town. I rode horseback this morning, and Milt Walker rode with me. Winthrop is about well this evening. His was the first sickness we have had. Will Musgrove came up with us while we were halted for noon--his train is a short distance behind--he rode with me in the wagon all afternoon, and drove the horses, and mother rode Dick. We had a long talk about friends at home. He took dinner with us, and then said good-bye, and we will see him no more, for we will travel faster than the freight train. * * * * * Wednesday, June 21.
