A smaller spraying outfit may he prepared by mounting a 

 suitable pump on a barrel or cask, the whole being fastened 

 in a wagon or cart. Among other pumps used for this pur-

vented by Mr. E. C. Ware of the gypsy moth force. It is 

 light, strong, and the couplings cannot be forced off. No 

 feature of spraying operations is more exasperating or ex-

 and leaking of couplings. With the small hose and coup-

 spray-poles use a one-quarter-inch gas pipe, ten feet long, 

 encased in wood, with a coupling at one end for the hose and 

 at the other for the nozzle.
