 get, and pasteboard boxes are gladly given away by 

 stationers and dry-goods dealers. Any boy or girl who 

 has a little knowledge of tools can make setting-boards,

 and a pipette costs five cents. Chloroform costs more, 

 but need not be used at all, though it is sometimes

 curacy, and patience are absolutely necessary to satis- 

 factory work of this kind.

 this way one can sometimes obtain a species that has 

 been longed for but never found. 



It is not very often that a whole brood of cater- 

 pillars can be reared successfully. Accident, disease, 

 parasites — if the larvee were found out of doors —
