728 Report or EntromMonogist OF EXPERIMENT STATION. 
of Sidney, N. Y. The protectors are made of cloth supported 
by light wooden frames and cost but a few cents each. They 
have given good satisfaction at this Station. 
As soon as the vines are uncovered, however, they should be 
sprayed with either London purple or Paris green, using, as 
before directed, one pound of the poison to about 150 to 200 gal- 
lons of water with the addition of two pounds of fresh-slaked lime. 
If it is preferred the poison may be applied dry, being mixed 
with plaster, air-slaked lime or flour, at the rate of one part 
by weight of the poison to about 20 parts of plaster or other 
substance used. In cases where the insects continue to appear 
in unusual numbers the application of the. poison should be 
repeated several times. Much pains ought to be taken and the 
work done thoroughly. Tobacco dust, when applied liberally and 
presistently on the hills and vines, has been found effective in 
keeping the beetles away. Air-slaked lime also is recommended 
and should be applied in the same manner.as the tobacco dust.
