(19) so it would appear that its resistance has at last broken, at least partly. In which case, if MR. Brock is right, I have the sexes reversed; but the notes will continue present designations. February 25 th. At 8 A.M. both birds were carrying lining to the nest. It was all soap-root fibre. The rope ravellings provided for them were not being taken. They were not too busy to come to breakfast ; the female bringing her load of lining with her and dropping it by my hand. She then stood on my hand and ate soft food placidly. The other was edging up closer and closer when a rabbit suddenly dashed into the glade and some small bird siunded an alarm note, whereupon both thrashers let go everything and bolted into the brush. It was several minutes before they would venture out again; but both finally came to me after some coaxing, both bearing soap-root fibre. This time the sun was at my back and there is no doubt of the distinct difference in eye color. The female's is abright orange brown; the male's is duller and "colder", as if green had been mixed with it, giving an olivaceous hue. I think I can"see" the green, though this may because of the knowledge that a green pigment mixed with a brown in the right proportions would give this color. I cannot vouch for the correctness of the color designation, as I have no standards with which to make comparison, but the difference is marked. I could see no differences in markings or throat color, but the male gives the impression of being younger and less sophisticated. I know none of the ornithologists' ways of determining ages. The female shortly went back to work again and the male was about to take soft-food from my hand, when a robin made a clumsy landing in the old oak overhead and he rushed to cover. He is far more timid t than the other bird.
