look over its columns!" "I see you're right," replied Casteno, as, springing to his feet, he snatched up his boots and hastened as rapidly as he could down the stairs, with the result that in a few seconds we had crossed the lawn and reached the shelter of the belt of trees near the boundary wall by which we had effected our entrance. Here we set to work, and quickly removed all traces of our adventures; then, hoisting ourselves over the wall that divided us from the side lane, we raced back as hard as we could in the direction of the town. "We must eat," he argued; "eat to live. Everything just now depends on us keeping in the pink of condition. To do that we must never neglect our food."
