with his cousins who are reputed to swallow caterpillars, "fur" and all, lining their gizzards eventually with a coating of the hairs which embed themselves in the inner coating). I expected him to bolt it, but instead, still holding it carefully, so as not to break its skin (?) he rubbed it carefully on the board floor of the plat- form. For a reason not apparent at the time, this did not prove satisfactory. (There was absolutely no "killing" action). He took it to the hard, but sand covered, ground and rubbed off, much to my astonishment, every vestige of the long hairy covering, with- out breaking the skin, until the caterpillar was a smooth, grey, hairless worm, looking like the fat cut-worms that Brownie extracts from the lawn. (The ground furnished the sand-paper). These cater- pillars have very tender skins, yet the skin was unbroken until, manifestly satisfied that the creature was now properly prepared for consumption, Archie gave it a few whacks on the ground, ac- cording to best road-runner tradition, then gobbled it. This particular kind of caterpillar (larva of the Monarch (?) buttefly(?)) is very uncommon here at this place. I doubt very much if Archie had ever seen one before, yet he knew exactly how to handle it in every detail. At bedtime there was no conflict and the selection of beds was unchanged, Archie waiting a long time after T had retired bed before following suit. Thrasher situation remained unchanged. September 13th to 15th., incl. Up to 1;30 P.M. on the 15th. (the time at which this memoran- dum is being written), there has been little change. Roadrunners Bedtime behavior unchanged, A holding back before settling permanently long after T seems well settled for the night. There is some mutual suspicion.
