Glen was more than glad to find himself once more on Nettle's back, and again bearing the front flag in advance of the party. He was also surprised to find what a barren place the valley that had looked so beautiful and desirable from the mountains really was. Its sandy soil only supported a thick growth of sage brush, that yielded a strong aromatic fragrance when bruised or broken, and which rendered the running of the line peculiarly toilsome. It was a relief to reach the great river of New Mexico, and find themselves in the more fertile country immediately bordering on it. Here, too, they found numbers of quaint Mexican towns, of which they passed one or more nearly every day.
