so stopped to consider the matter. This process involved his standing in front of the mirror, thus affording him a way out of the dilemma, since forces beyond his control made it necessary to tap the "other" bird and display for his benefit, following up by making the grand, outside circuit of the cage to determine whether the other fellow was lurking in the bushes behind it. This gave me the opportunity to slip out and watch further proceedings when he completed the lap. As expected, he immediately entered the cage, got his meat and then stared, round-eyed at the other birds. His attention was concentrated mostly upon the rail, who stood near the mirror. Rhody dashed back and forth along the wire trying to get in to the rail, spreading his wings and tail. The proximity of the rail and the mirror, especially the latter's appearing out from behind it in the midst of Rhody's evolutions, I imagine, formed a picture fitting in more or less with the road-runner's vague anticipations, if any. Certainly the rail, in a superficial way, is not unlike a small road-runner that has lost its tail. In any case, Rhody got quite excited over the combination and wound up by again making the grand circuit in record time, following up by ridiculous posings behind bushes, rattling of beak and cutting of swift figures of eight amongst the trees, ending with a final boo and a dash for the glade, as if disgusted with the futility of everything. Dec.21st. Another heavy fog, but Brownie singing in the early morning as usual. I found Rhody still in his roost at 11 A.M.--the latest to date. I do not know how much longer he would have stayed there, but when I showed him a worm, he came down to me without hesitation, picking through his way carefully through the branches and walking on the porch of the house which I made for him, but which he will not use otherwise.
