top and two inches deep. The large nappy is known as No. 

 7, and is nine inches in diameter and two and a half inches 

 deep. The large one is given to the pigeons first to receive 

 the eggs. When the squabs are two weeks old, the large 

 nappy is removed and the nest with its occupants transferred 

 to the small one. The reason for the change is this : The 

 nest which the breeding pigeons build in to receive the eggs 

 should be large so that the cock and hen will have plenty 

 of room to cover the youngsters and protect them from the 

 cold. In winter time especially the)'^ are very careful not to 

 leave their tender young uncovered long enough to be 

 chilled. The squabs deposit their dung in a circle inside the 

 nest. At the end of two weeks when you change nappies, 

 you get rid of the dirty nest and at the same time provide 

 a nappy in which there is plenty of room for the squabs, and 

 also you have a self-cleaning nest, for the youngsters deposit 

 their dung over the edge of the nappy into the nest-box, and 

 not into the nappy, as they would do if you allowed the large 

 nappy to remain. In the large nappy, also, some squabs, if 

 left to develop, will become deformed, owing to the fact that 

 their feet will push the nesting material off the slippery bot- 

 tom, on which their legs will sprawl disjointed. • 



FLYING^PEN AND FITTINGS. 



The flying pen is simply a wire yard. It is as wide as the 

 squab house, and as high, and extends toward the south 

 about twenty feet. Set posts at the southern extremity and 

 stretch the wire to them, ^ides and top. The top of the
