driveway containing plentiful quantities of mouse-hair. At 12:40, after several minutes' search I found him sitting about 10 feet up in the adjoining tree. He wanted no more food. Rhody casts pellet. As I talked to him, he shook his head, looked down and I heard something drop upon the dry leaves near me. Search revealed- a fresh pellet covered partially with a fine froth. To the eye it appeared to be all mouse-hair. It was preserved. Dawson, Bryant and Sutton say no pellets. Both Bryant and Dawson say that the road-runners do not cast up pellets. Sutton says his pets, Oberon and Titania, did not. Probably longer periods of observation on individual road-runners feeding largely upon mice would have yielded the same results as my observations on Rhody, Archie, Terry and Pepper, all of whom cast up pellets of mouse-hair, but spaced at long intervals of time. Further comment on present pellet. In the present instance little effort was required and it is worth noting that, although Rhody had eaten heartily of meat with in the hour, no meat showed in the pellet. Also, he had had no mice today. Further, except for the meat, the evidence is pretty conclusive that he had had nothing to eat since a little after 2 P.M. yesterday, and certainly no mice . These notes have suggested, bearing in mind that mouse fur is always voided plentifully with the excrement and that pellets are disgorged only at long intervals, that the road-runner may be "sick", in the sense of being unwell, when it resorts to this method of getting rid of the accumulation of fur. Also it may be "sick" in the sense of being nauseated. The fact of Rhody's remaining so long inactive on this occasion, though fully awake, may be an indication of discomfort within his internal economy, although the simplest explanation is that there was "just simply" nothing else for him to do. It now remains to be seen whether his retreat to the tree means that he is going to bed early. 1:45 P.M. Well, Rhody is a surprising creature. At 1:30 I found him sitting quietly in exactly the same spot where he cast the pel- let, but this time, when I stood near him, he began to look down at the ground for a good spot upon which to light and when I moved off sailed down and trotted along behind me on the sidewalk to the en- trance, where he stood quietly beside me while I explained to two delighted who came out from behind a truck to look at him, who he was, where we were going and what Rhody's aspirations at the moment were. When I started up the driveway Rhody found the pace too slow to express his exuberance of spirits and, with raised crest and colors displayed, made fancy excursions to right and left, arriving at the door of the tool-house in a dead heat with me. He was full of pep and gobbled the huge, black mouse handed him with alacrity. Evidently the clearing out of his pipes did him good and left space that needed filling. All this was totally unexpected. I had thought to find him finished for the day. At 3:15 I found him in sleeping posture on the support of the new house in the peppermint gum tree. My guess had been that he would occupy his old house, but he fooled me. Several observations at irregular intervals until dark showed him still there. At 8:25 P.M. he was still there, the tree swaying somewhat in the southerly wind, which has freshened a bit. (Cloudy, 59°). I don't understand this animal at all! Nov. 23rd. Rain during the night. Trust Rhody, in his present aberrant mood, to have selected the wrong night in which to sleep out!
