You can buy this boxing at a saw mill all cut, ten by eleven 

 inches, the dimensions of the nest, and if you get it in this 

 shape )'ou can put the boxes together with as much ease as 

 a child builds a doll's house. You will have no doubts as 

 to the squareness and plumbness of the structure when you 

 have it up. Take long lengths of boxing eleven inches wide 

 for the, shelving which should form the top and bottom of 

 the nest-boxes, then set the lo in. x ii in. pieces the proper 

 distance apart. The finished nest will be eleven inches from 

 front to back, ten inches from top to bottom, and about ten 

 inches from one partition to the other (or whatever distance 

 the proper distribution of yoitr nests in pairs permits) .„ 



We have found five-eighths inch boxing to be the best 

 suited. Build the nest-boxes up from floor to roof perfectl}'' 

 plain, just as the pigeon holes of a desk run. When you 

 have got them -up take two-inch strips of the boxing and 

 separate each pair of nests by tacking the stripping onto the 

 edges where they project out into the house. The object 

 of this stripping is to make it harder for a pair of birds in 

 one nest-box to disturb the pair in the adjoining box. Be- 

 tween the nest-boxes of the same pair there should be no 

 stripping. 



The backs of the nest-boxes should be on hinges so that 

 from the passageway you may examine every nest. Give 

 each pair of nests a number and it is possible to keep an 

 extremely accurate record of each pair of breeding birds. 

 This record may be kept in a book, numbering the pages 

 to correspond to the number on a pair of nests. A better
