COLLECTING AND PRESERVING EGGS. 79 



The measurements of an egg are taken with the dividers 

 in hundredth** 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 nioths.
