COLORADO EXPERIMENT STA TION. 
the stem after forming, it is probably advisable to 
make the first application not later than one week 
after the flowers fall. If the application is thor¬ 
oughly made, and no heavy rain follows to wash 
away the poison, a second application will hardly 
be needed. If a heavy rain does follow soon after 
the first application, the trees should be sprayed 
again with a some what weaker solution than at 
first. 
As to pumps and other machinery with which 
to make the applications see article on spraying 
machinery. 
COLLECTING UNDER BANDS. 
Next to the arsenites the use of bands fastened 
around the trunks of the trees about the last of 
June, under to which to collect the larvae of the 
first brood for the purpose of destroying them is 
probably most useful if faithfully attended to. The 
bands may be of hay, paper, burlap or other cheap 
material that will form a good hiding place for the 
insects while in the pupa state. These bands must 
be inspected every three or four days and the lar¬ 
vae and pupae found beneath them destroyed. In 
this manner the second brood, will be largely pre¬ 
vented from appearing. 
Another partial remedy is to allow sheep or 
swine to have the run of the orchard as they will 
destroy large numbers of the worms that are in the 
apples when they fall. 
USELESS REMEDIES. 
There are many who suppose the moths may 
be easily captured in dishes of sweetened water or 
of milk, or about lights put in an orchard. These
