Bulletin No. 21. 59 



After a few introductory remarks relating to the literature, location 

 and fauna of the county, the author presents a pretty fully annotated list 

 of the birds which are known to nest in Susquehanna county. The list 

 comprises ninety-one species, five of which the author considers hypo- 

 thetical, not having been actually found breeding by him. Similar lists, 

 prepared by, as trustworthy observers, throughout the country, would 

 give us a basis for maps of life areas which would need very little future 

 modification. 



Charts of North American Birds. Published by Mature Study 

 Publishing Company, Chicago. 



These charts comprise eighteen sheets, representing 142 plates of birds 

 and three plates of eggs. One of the bird plates is repeated, thus leav- 

 ing 141 species of birds represented, while there are forty-nine species 

 of eggs represented on the three plates. These plates have already 

 appeared in that unparalleled magazine — Birds — and so need not be 

 given individual attention here. For the first time they are here grouped 

 in more or less natural order, as one finds them associated together in 

 the fields. These groupings must be seen to be appreciated. They are 

 certainly a work of art. It is too much to expect that a work of this 

 kind should not have some defects or some possibilities for improvement, 

 but it is cause for congratulation that there are so few necessary changes. 

 The third cover-page is devoted to an outline bird at the top with the 

 printed names of all the parts illustrated. It is cause for regret that this 

 figure and the labelling is unworthy of the company in which it has 

 been placed. It is earnestly hoped that it will early be supplanted by 

 an accurate figure. The lower half of the page presents an alphabetical 

 list of all the birds represented on the plates, with first, the A. O. U. 

 number, common name, small figure referring to the collection from 

 which the subject is taken, scientific name, and the plate number. In 

 this list we notice only two errors. The generic name of the Belted 

 Kingfisher should read Ceryle instead of Alcedo, and the Nonpareil, or 

 Painted Bunting should be given the A. O. U. number 601. One can 

 appreciate the difficulties of an undertaking of this kind only when he 

 attempts any arrangement of the Nature Study plates of birds. These 

 charts are printed on strong manilla paper, which is reinforced on three 

 edges with cloth. The twenty sheets are securely fastened in a solid oak 

 stick which is supported on an adjustable tripod, the whole weighing but 

 a few pounds. We predict a wide sphere of usefulness for these charts.
