mated by earnest and intelligent attention during the opportunities for 

 study. The mind must be trained to receive the impressions which eye 

 and ear are constantly bringing to it. Probably the most of us are able 

 to retain enough of a song, even once heard, so that we shall be able to 

 recognize it weeks or years afterwards if it be repeated, but I doubt if 

 more than a chosen few could imitate successfully even a small pittance 

 of the more common songs and notes heard nearly every day. Then a 

 secondary mission of our Chapter must be the training of the faculties 

 for more careful and profitable study. 



What have we done that will furnish assurance of future success ? 

 There is but one published report that is worthy of our high ideal — the 

 Crow Report, Bulletin No. 4 — , but there are others under way. Mr. 

 Frank L. Burns, the compiler of the Crow Report, has a similar work 

 on the Flicker well under way, besides the several other investigations 

 mapped out, for which see Bulletin No. ig, page 26. It is earnestly 

 hoped that these reports may be pushed to an early completion and pub- 

 lished. Your investigations will contribute largely to this end. 



PUBLICATIONS RECEIVED. 



Bird Tablet, for Field Use. By Josephine A. Clark, 1322 Twelfth 

 St. N. W., Washington, D. C. Price twenty-five cents. Special rates 

 to schools and classes. 



In this Bird Tablet, Miss Clark supplies the need which every be- 

 ginner must feel of a printed form which will at once furnish a record 

 book which will enable the student to go to his key with a fair prospect 

 of arriving at the correct identification of the bird seen, and also train 

 him to look for the more essential points of structure, markings and 

 habits. The beginner is too often led to stop with general impressions, 

 giving little or no attention to details. This Tablet will correct that 

 tendency, and prove to be an educator to eye and ear, and lead to a 

 habit of discrimination, so necessary in the study of birds. There are 

 fourteen main heads, with sub-heads under the most of them, and 

 usually ample space left for annotations, besides two full pages for 

 " Notes." While the printed descriptions are not intended to be exhaus- 

 tive, they are sufficiently detailed to furnish a basis for intelligent work. 

 Beginners in bird study will find this Tablet a useful field companion.
