Tired from a long day's work in the laboratory, I wandered slowly along the Convict Trail, aimlessly, in that wholly relaxed state which always seems to invite small adventures. It is a mental condition wholly desirable, but not to be achieved consciously. One cannot say, "Lo, I will now be relaxed, receptive." It must come subconsciously, unnoticed, induced by a certain wearied content of body or mind--and then--many secret doors stand ajar, any one of which may be opened and passed if the gods approve. My stroll was marked at first, however, by only one quaint happening. For several weeks the jolly little trail-lizards had been carrying on most enthusiastic courtships, marked with much bowing and posing, and a terrific amount of scrambling about. The previous day--that of the first rains--numbers of lizardlets appeared, and at the same time the brown tree-lizards initiated their season of love-making. I had often watched them battle with one another--combats wholly futile as far as any damage was concerned. But the vanquished invariably gave up to his conqueror the last thing he had swallowed, the victor receiving it in a gluttonly rather than a gracious spirit, but allowing his captive to escape. I surprised one of these dark-brown chaps in the trail and seized him well up toward the head, to preserve his tail intact. Hardly had I lifted him from the ground, when he turned his head, considered me calmly with his bright little eyes, and forthwith solemnly spat out a still living ant in my direction. The inquiring look he then gave me, was exceedingly embarrassing. Who was I not to be bound in chivalry by the accredited customs of his race? With dignity and certainty of acceptance he had surrendered, calmly and without doubt he had proffered his little substitute of sword. It was, I felt, infinitely preferable to any guttural and cowardly "kamerad!" Feeling rather shamefaced I accepted the weakly struggling ant, gently lowered the small saurian to the ground and opened my fingers. He went as he had surrendered, with steadiness and without terror. From the summit of a fallen log he turned and watched me walk slowly out of sight, and I at least felt the better for the encounter.
