for a mouse. Part way there he cut across lots by a shorter route and reached the yard as soon as I did. This act would appear to indicate that he is capable of looking ahead to an objective andomit customary intermediate links in the pattern. I.e. he has learned that a mouse is to be expected when he goes to the hop whether he follows me all the way or not. When he reached the gate on his return journey he gave a sudden start as if frightened by something, came back, began his ritual, then considered going over the wall instead of taking his usual route through the gate. There was no enemy in sight. At last he went out the gate and stopped at the lath-house, looking up, just as I had caught a glimpse of some small object running across its roof. He started to go inside, still looking at the roof, then changed his course and went around to a pile of boxes at the eastern end, under a pine tree. Here he seemed nervous, but soon came out, continued his ritual and carried the mouse to 5-36 via the mirror. I then went to the boxes and a chipmunk ran out (only the sec- don one seen at this place in 9 years. An escape?). Doubtless curiosity about this animal, with perhaps some element of fear, explains his departure from regular routine. At 11:45 Rhody was at the boxes again apparently looking for the chipmunk. From there he went to the roof of the lath-house and whined. when I went to see how the snake was faring, Rhody came also, taking his time about it. He again whined. At first I thought that this whining might have something to do with his inability to find the chipmunk, but when I turned toward the shop Rhody followed and was given another mouse. This mouse was no smaller than those that Archie had to beat to death, yet Rhody killed him with one squeeze. Full ritual followed and at 12:12 he took the mouse to 5-36. At 12:55 P.M. Rhody was sitting quietly in his nest as I approached. When I spoke to him he looked down at me, stood up and began to rearrange twigs and adjust the lining almost furious- ly, as if piqued at being discovered loafing on the job. This is about the nth time this has happened. I wonder what is really back of this behavior. Superficially, of course, it looks very human. The point where Archie was liberated is 16 miles from here by the shortest road, but, due to the hilly nature of the country, is only about 9 miles as the crow flies. I went there again in the afternoon, seeing no signs of Archie, and talked to another of the patrolmen (Smith). He sees road-runners in the vicinity "every day", and likes them. Their antics amuse him. From here to the place where we recaptured Archie is 5 miles by street, but, as the crow flies, less than 4. Rhody still sleeps in the oak on the west lot. Brownie, since his brood has grown up, now spends a great deal of time off to the south-west. July 2nd. Rhody from 8 A.M. to 11:30 A.M. At 8 A.M. Rhody was in the cage, watching the magpies, who have now returned to his favor (or disfavor?). For the next
