32 THE AUDUBON BULLETIN 



A Working Library of Bulletins 



Readers of the Spring Bulletin are again reminded of the aid which 

 the U. S. Government gives in the way of carefully prepared bulletins 

 setting forth the economic importance of birds and detailing methods of 

 attracting and feeding them. In the following paragraphs material 

 printed in the Spring, 1917, Bulletin under the same heading as above, is 

 reproduced with revisions and additions, the value of the material being 

 deemed of sufficient importance to justify its reappearance in this if not 

 in succeeding issues of the Bulletin. As to schools availing themselves of 

 these bulletins it is suggested that the teachers write for the bulletins and 

 distribute them rather than encourage indiscriminate application by chil- 

 dren who may not realize the value of the material thus freely given away. 

 All the Bulletins mentioned with one exception to be noted, are to be had 

 free of charge by writing to the Department of Agriculture at Washing- 

 ton. When the limited supply of free publications is exhausted, appli- 

 cants are referred to the Superintendent of Documents, Government Print- 

 ing Office, Washington, D. C., who has the publications for sale at a 

 nominal price. 



Farmers' Bulletin No. 621, "How to Attract Birds in Northeastern 

 United States," by W. L. McAtee, describes bird shelters and methods of 

 feeding birds, and contains a very complete list of fruits attractive to birds. 

 Farmers' Bulletin No. 912, "How to Attract Birds in the East Central 

 States," in press at the date of issue of this Winter Bulletin, will 

 doubtless prove of peculiar interest in this area. Farmers' Bulletin No. 

 609, entitled, "Bird Houses and How to Build Them," by Ned Dearborn, 

 has numerous detailed drawings and covers the subject completely. With 

 these two bulletins at hand, one of 15 pages, the other of 19, one has a 

 good working library to start with. Farmers' Bulletin No. 493, "The 

 English Sparrow as a Pest," by Ned Dearborn (24 pages, 17 illustrations), 

 treats the subject authoritatively and completely. It should be studied and 

 its suggestions followed up everywhere in our state. Bulletin No. 630, 

 "Some Common Birds Useful to the Farmer," by Beal (27 pages with 

 illustrations), treats of 25 groups of birds. This bulletin together with 

 Farmers' Bulletin No. 497, "Some Common Game, Aquatic and Rapacious 

 Birds in Relation to Man" (30 pages, 14 illustrations), by McAtee and 

 Beal, and Farmers' Bulletin No. 506, "Food of Some Well Known Birds 

 of Farm, Forest, and Garden" (35 pages, 16 illustrations), by the same 

 authors, should be added to one's working library. The following bulletins 

 are recommended in addition to the above : 



Department Bulletins. 



205. Eleven Important Wild-Duck Foods. 



465. Propagation of Wild-Duck Foods. 



619. Food Habits of the Swallows (In press). 



621. The Crow and Its Relation to Man (In press).

504. Plants Useful to Attract Birds and Protect Fruit. 

 642. Our Shore Birds and Their Future. 



Biological Survey Circular No. 17, Bird Day in the Schools, will prove 

 helpful to program makers.
