for placing before the birds, in all weathers, food that shall be acceptable, 

 accessible and cheap). 



3. Fighting the enemies of birds. 



After examining a number of holes of different species of Woodpeckers, 

 and noticing that they were all built on the same general plan, Baron von 

 Berlepsch finally succeeded, with the help of special 

 machinery, in making out of sections of trees some 

 remarkably good imitations, which he attached to the 

 trees in his park and woods, and with the most 

 astonishing results. 



There are three types of these boxes manufactured: 

 A, A^, B, C and D, vertical, and of various sizes; E, 

 horizontal; and F, cup-shaped, with an open side. 



A, with the entrance hole 32 mm. in diameter, and 

 about the size of those made by our Downy Wood- 

 peckers; and useful also, I should say, for Tree 

 Swallows, and White-bellied Nuthatches, if they can 

 be persuaded to build in them. 



A\ with the entrance hole 27 mm. in diameter; 

 useful for Chickadees, and House Wrens (and too small 

 for English Sparrows). 



B, with the entrance hole 46 mm. in diameter, of 

 the size best adapted for Bluebirds. 



C, with the entrance hole 60 mm. in diameter, 

 readily adopted by Golden-winged Woodpeckers and 

 Screech Owls. 



D, with the entrance hole 85 mm. in diameter, for 

 which there seems to be no especial call here in New 



England, although Golden-winged Woodpeckers and Screech Owls would 

 doubtless use them if they could not get the smaller sizes, and possibly 

 Sparrow Hawks. 



Of the other two types, E is a horizontal box with the hole in the end, 

 •which, Mr. Hiesemann says, is "for Swifts," and which, in this country, might 

 be utilized by Tree Swallows (and doubtless by English Sparrows); while F 

 is an open-sided cup-shaped arrangement, which, the author states, "Is made
