Our earlier plans had been so sadly upset that we now found ourselves without food or drink, and I alone was armed. We therefore urged our beasts to a speed that must tell on them sorely before we could hope to sight the ending of the first stage of our journey. We rode all night and all the following day with only a few short rests. On the second night both we and our animals were completely fagged, and so we lay down upon the moss and slept for some five or six hours, taking up the journey once more before daylight. All the following day we rode, and when, late in the afternoon we had sighted no distant trees, the mark of the great waterways throughout all Barsoom, the terrible truth flashed upon us—we were lost.
