May 13th we camped at a large spring, usually called the Vegas. The country through which we have passed is worthless desert . . . The longest distance without water is about 50 miles . . . We have as yet lost no cattle through hunger, thirst or fatigue. Two cows were stolen from us by the Indians . . . Since leaving Vegas we have traveled seventy-five miles through a most horrible desert.
