where they can get it easily and see if they will use it. I will tear it to pieces first. 9:30--I will do it now. 9:46. It works. When I went out a bird was still on the nest sitting quietly, impervious to calls. I distributed the fibre partly on the ground under the tree where I sit and partly in the branches , noting that in the original nest the lower layers of the lining consisted of ribbons from the soap- root bulb before it had broken up into its constituent fibres. The bird in the nest, which proved to be Brown-eyes, climbed down and began gathering up soap-root ribbons--not those I had just put there, but others, carrying them up to the nest, which, up to that moment, contained nothing but twigs. I seem to have hit the psychological moment exactly. After two trips she came over to me and began gathering up the fragments of the old nest, selecting the ribbons, and carried them up to the nest. She was perfectly friendly, but entirely without interest in my offerings of food, chirping to me , but too much absorbed in work. Green-eyes soon appeared in the glade, alternately picking up ribbons and dropping them to dig for food. He did not take any to the nest during the 15 or 16 minutes I was there 9:57--raining. ( I shall now prepare a feeding station for Bullock Orioles. Mr. Brock is "breaking in" some wild ones which he caught yesterday, and will liberate them at my place in order to determine whether they may be induced to nest here. Orioles come here, but, so far, have not nested here. Mr. Brock, who suggested the experiment, thinks the conditions here justify the attempt).(While my own observations are limited, in past years, I have been accustomed to think of these birds as nesting in the valleys and sheltered canyons rather than on top of a projecting spur; I planted a weeping willow for the especial benefit of orioles a couple of years ago, but it was
