off with the prize. Brownie accepted the defeat without resentment, but made several audible comments. Later in the afternoon I placed a glass house in the tree about 2 feet from the thrasher nest. This house is about 43 inches long, 15 inches wide and 12 inches to the eaves. Except for the light frame, it is entirely of glass, and has no floor. The glass spots of is daubed with green paint in an effort to simulate the appearance of foliage as seen from the inside. A few perches of different diam- eters are placed inside. The object is to see if birds of any kind will use it as a shelter in inclement weather; but primarily if the thrashers will use it. If the thrashers should, it is considered improbable that more than one will use it at the same time, due to what appears to be their propensity for roosting apart. Two panes of glass are omitted on each side near one end to allow of side entrance if preferred. October 8th. At 8 A.M. Brownie was in the nest sitting quietly. I went to the glade and called. Greenie came for one worm, gathered fibre and went toward the nest. I got there first. He walked over the roof of the glass house and relieved Brownie, who then had a few worms and then began gathering fibre. The presence of the house does not seem to bother them. The house gives no shelter to the nest, but is so located that the birds can not fail to pass near it in their trips to and from the nest. 10:45. At 10:30 I went to observe the thrashers' reaction to the house. Brownie was in the nest. Greenie soon came with soap-root. Much to my delight, he included the house in his route, entered at one end, used the perches and came out the other end, thence to the nest. Brownie on leaving, used the same route. On returning ditto. More dittos. Greenie, on leaving, ditto. Brownie on returning, ditto. I then left to record this observation. So, then, they know all about the house, inside and outside, already, and I hope that its attractions will appeal to them as a shelter. I wish the nest was inside of it.
