On this morning I had chosen a new street to explore when suddenly I found myself at the limits of the city. Before me were low hills pierced by narrow and inviting ravines. I longed to explore the country before me, and, like the pioneer stock from which I sprang, to view what the landscape beyond the encircling hills might disclose from the summits which shut out my view.

It also occurred to me that this would prove an excellent opportunity to test the qualities of Woola. I was convinced that the brute loved me; I had seen more evidences of affection in him than in any other Martian animal, man or beast, and I was sure that gratitude for the acts that had twice saved his life would more than outweigh his loyalty to the duty imposed upon him by cruel and loveless masters.
