50 NATIONAL STANDARD SQUAB BOOK 
They will not build nests with dirty nesting material. It must 
be first-class, clean, dry and sweet or they will not use it. 
Some of our customers use pine needles successfully for 
nesting material We have never tried them because they 
are not plentiful around our farm. Where they are in abun- 
dance, we recommend that they be tried. 
When a new lot of pigeons are placed in a squab house,

Fill this berry crate with nesting material (straw cut into six-inch lengths, and 
hay, mixed about equally) and place it in centre of squab house. The cover prevents 
the birds from fouling the nesting material. They stick their bills through the slats, 
select the wisps they want, and fly to nests,
