New York AGRICULTURAL EXPERIMENT STATION. 357 
this arsenical showed no injury to the leaves it is possible that 
the compound was not properly prepared. Further experiments 
with this compound are needed. No more larvee appeared on the 
sprayed bushes so that a second application was unnecessary. 
Plat III, which was unsprayed, was nearly stripped of its leaves 
before the season was over, so that but little first-class fruit was 
developed. Plate XXIX is from a photograph taken in the field. 
The bushes on the left were HE ha with hellebore, those on the 
right were unsprayed. : 
Dry application of hellebore.— says dered hellebore may be ap-— 
plied pure or mixed with twice its weight of cheap flour or land 
plaster. It should be dusted on early in the morning or in the 
evening while the leaves are moist with dew. The principal ob- 
jection to this method is the difficulty of applying to the under 
surface and in making it adhere to the leaves. 
RECOMMENDATIONS. 
The treatment for this insect and insects of this class is usually 
a very simple matter. As indicated by the above experiments 
the prompt application of hellebore will check them, and in the 
case of this species, brushing the larvee off from the bushes can 
be made effective. Where a sprayin® machine can be had it will 
be found that a more thorough application can be made with the 
spray. Make the applications thorough, drenching both upper 
and under surfaces of the leaf.
