SINGLE NEST-BOX 

 CONSTRUCTION. 



(See Upper Picture). 

 When the nest boxes are 

 built of lumber (one-half 

 an inch or five-eighths of an 

 inch thick) the construc- 

 tion shown in the upper 

 drawing (surrounded by 

 black line) should be em- 

 ployed. The bottoms are 

 not nailed, but slide in on 

 cleats as shown. The re- 

 sult is a sliding shelf. This 

 shelf may be pulled out at 

 cleaning timeand a better 

 and quicker job of cleaning 

 done. The nest bowl^s 

 may be screwed directly 

 to the bottoms of the nest 

 boxes. If that is done, it 

 will not be necessary to 

 screw the nest bowls to 

 blocks of wood, to give 

 them stability. The nest 

 boxes should be from ten 

 inches to twelve inches 

 square. 



DOUBLE NEST-BOX 

 CONSTRUCTION. 



(See Lower Picture.) 



This double box is 

 favored by many. It is 

 comparativeljr new in de- 

 sign. The picture was 

 drawn and this description 

 was written in February, 

 1913. Pages 45 to 50 of 

 this book were put into 

 type and plates made be- 

 fore that date. This 

 double nest box is a good 

 one. The box has two 

 feet frontage. The re- 

 movable centre piece is 

 ~ fourinches high, two feet 

 frontage and one foot 

 deep. The shelf or base- 

 board, also removable, is 

 deep enough so that 

 a porch (or perch) four 

 inches wide is left for the 

 birds to alight on. This 

 ^elf , or baseboard, slides 

 on cleats, so the whole 

 ''»,rp;;'r' arrangement, except the 



'^ vertical uprights, takes 



apart for cleaning. The 

 nestbowls.twoin number, 

 are screwed to the baseboard in the centre of the two squares formed by the removable 

 centre piece. Some builders prefer the single nest-box construction, others the double. 

 It is a matter of individual preference. Eada style is good and we endorse both of them.
