in matrimonial prospects. When I looked him up, greeted me with a mild rattle-boo: also the first heard from him for a long time. It will be interesting to note whether the mirror, which he has neglected for the past few months, will again prove attractive, thus, perhaps affording some clue as to whether his cavortings before it are in some way linked with aroused reproductive impulses He still uses the pine as a night roost, going to it about 3:15 P.M., not apparently influenced by weather conditions. January 16th. to 20th., incl. During this period Rhody continued his spring song, wandering from tree to roof, closely following last year's procedure, never going far from this place and sleeping in the Scamells' pine every night. By looking up last year's notes I find that his first song of the season was on January 31st., so that he is 16 days earlier this year. I can not see that he shows any greater interest in his off- spring than usual, and they, in turn, while they plainly listen to him when he calls nearby, show no excitement although Terry once seemed to respond to one of his first calls by uttering one of his rare Hrooh, hro-o-ohs and then relapsing into indifference. more It begins to look as if Archie and Terry were now nearly of the same size than formerly, making due allowance for Archie's wider and heavier tail.

However, he got out of control just a few minutes before the arrival of the visitors, although we followed him up and had a fair look at him despite his fear of the unusual number of persons present. January 21st. to 24th., incl. No change in the weather. Rhody wandering somewhat further in his search for a partner. Archie and Terry were weighed with the household scales; this time Archie was the more accommodating and decided that the instrument was a good place to lie on and have a good rest. It recorded him as weighing 12 or 13 ounces, depending upon what portion of the pan he occupied. (The scales are very insensitive). Terry's weight (on one trial) was recorded at 12 ounces.
