The others agreed, and they at once started across the country, which was only cultivated here and there. They laid their course so as to strike the canal at a point some miles higher up than that at which they had left it. They only saw a few peasants in the fields, and made detours so as not to come near any of these. On the way they picked a dozen heads of maize, but were too thirsty to attempt to eat them. After three hours' walking the vegetation became brighter and greener, the cultivated fields thicker, and in another half hour they stood on the bank of the canal. They went down to the edge, knelt down and took a long drink.
