COLLECTING AND PRESERVING EGGS. 79 



The measurements of an egg are taken with the dividers 

 in hundredths of an inch. The number is attached to the 

 nest. Nests, if composed of loose materials, must be kept 

 in boxes, separated from each other ; if lined with feathers, 

 benzine should frequently be applied, to prevent their being 

 attacked by moths.
