The attitude of the first class towards the second was rather puzzling. The restriction of the numbers of the workers was quite ruthless. Children that were not wanted were destroyed as we destroy superfluous kittens, fewer girls than boys being allowed to live. The punishment of death was given for any act of disobedience, and even, after due warning, for carelessness and incompetence. But the workers whom I had seen so far--all men--were evidently well treated. They showed no signs of over-work, or under-feeding, or disease. They were tall, stout fellows, all of them, and evidently in fine condition. Not one of them adopted or attempted to adopt the quadrupedal position. They walked erect, and were obviously the physical superiors of their masters. Doubtless utilitarian views had prevailed with the first-class beings, and they gave such treatment to the second class as would ensure the maximum of effective work from them. The clothing of the workers was of the same thick woollen material as that of their masters, but of a different colour--a reddish brown. The men threw off their upper garment when working in the fields. It will be remembered that on my arrival I was provided by the late MZ04 with grey garments similar to those worn by the first class. I was thus in the nature of an anomaly to everyone who met me. I walked erect and therefore did not belong to the first-class beings. I wore the grey garments, the sleeves of which had now been abbreviated to suit me, and therefore did not belong to the second class. To tell the truth my stature was inferior to theirs, and would by itself have distinguished me. Standing on the crest of the hill I made my plans. It was in my mind to get away from this island as soon as might be. In a forest of that extent I might easily lie hidden for weeks, and I doubted if, with all his knowledge and cunning, the Professor would be able to find me. Meanwhile I would establish friendly relations with some of the second class. Living as they did upon the sea-shore, I expected that they would have contrived boats for their own use, and thus I might make my escape. I had the whole day before me, and began now to explore the forest, intending to go on to the village on the shore when the workers had returned in the evening. I followed the course of the stream that trickled down the hill-side. There was no wind, and except for the burble of the stream and the call of the birds all was still in the forest. Here and there the stream broadened out into wide shady pools, where it seemed to me there might be the chance of tickling a trout. Presently I heard below me a loud splashing. The trees and undergrowth were so thick that I could see but a very little way before me. I still followed the stream in the direction of the sound, but I went with extreme caution, taking care that my footsteps should not be heard. I did not know what danger might not be awaiting me below.
