way by the oval lawn, a tawny shadow dropped down from the back of a bench ten feet to my right and placed itself directly in my path, amost at my feet. Rhody. He now waited to see "what I was going to do about it". It was just as if he had been waiting for me, as perhaps he was. He took two or three steps away from me, waited, making impertinent movements of head and tail. When I advanced a step, he moved enough to maintain his distance, then waited. After this was repeated a few times he seemed to be satisfied that my in- telligence was of high enough order to encompass the fact of his being mouse-inclined and so he took a good lead, moving faster. All this resulted in his receiving a mouse at the tool-house. This time he was very animated in his bowing, hrooing and tail- wagging, and while his "cerebral vortex" caused him to deliberate long between moves, when his mind was once made up, he moved with unusual rapidity to the various points at which he was to show the mouse. First, a good session with his counterpart at the mirror, followed by a period of reflection and peering in various direc- tions for a clue as to the next step to be taken. The decision was in favor of nest 5-36. Instead of eating the mouse there, as ex- pected, he went through his ritual in the nest; found no solution of his perplexities there and sailed back to the mirror. Business finished there, deep thought pointed to window of the Scamell house (out of sight 150 yards away) as the next best probability. Rapid transit over his standard route brought him to the sidewalk in front, but a new dog staring at him from behind a gate, impelled him to run rapidly down the street to the west and cross over to the west lot, thence to the ladder tree. This was traversed in three minutes (a record for him?) and he was in the house-nest in the roost tree. Still he did not eat the mouse, but continued his ritual in the house, occasionally coming out of it as if to con- tinue his journey to a new objective. Apparently he could not t think of one, so after 10 minutes, gobbled the mouse and settled in the nest. There being no immediate prospect of further action: I left. During the rest of the day he was about the place much of the time: doing a little work on nest 8-37; having a long bout with the magpies, in which he got very excited, rattling and rattle-booi- ing. This performance covered a period of two hours, with occasion- al rests. About 5:30 P.M. I induced him to stop his nonsense and come to the tool-house. He stationed himself about 3 feet in front of me, looking at the mouse with indifference. The sun was directly behind my back; Rhody was facing me; I was crouching on the ground. Rhody, still keeping his place, now began a long series of efforts to disgorge a pellet. I could look directly down his brilliantly illuminated gullet. He opened his bill to its fullest extent, occasionally shook his head from side to side; "rocked" it about a horizontal axis and scratched the under side of his neck with his right foot (not using the left at all). His gullet could be seen to collapse. Sometimes his neck was fully extended, at others drawn back between his shoulders. In the latter position that portion of his throat just to the rear of the tongue tended to "turn inside out" and be pressed upward against the roof of his mouth. In the former position this did not occur. This perform- ance lasted two or three minutes and accomplished nothing tangible. He finally abandoned it, but continued to wait in front of me. This meant (as proved later) that the mouse offered was too large. Consequently a smaller one was produced. He was coming to get it when a car (K.H.D. and wife) came up the driveway and he retreat- ed precipitately. G.K.D.
