The nests of the tent caterpillars may be destroyed by hold- 

 ing a torch under them at a certain time of day when the cat- 

 erpillars are not feeding, and are gathered in their tent or nest ; 

 in this way the whole colony of caterpillars can be readily 

 destroyed. A torch such as is used in torchlight processions 

 is excellent for this work.

For efFectivc work the warfare against the grapevine-hop- 

 pers should be commenced early in the Fall season : 



A. — By taking or scraping off all of the loose bark and thor- 

 oughly spraying the trunk of the vine Avith Remedy No. 51, 

 or 64, or 65 ; this will dislodge and destroy the insects, and at 

 the same time destroy the fungus spores on the vine. As soon 

 as this work is done, a flock of sheep should be placed in the 

 vineyard to eat the fallen leaves and keep down the growth of 

 alfilaria and grasses upon which the insects, such as may 

 escape, will feed on warm days. Grasses and weeds around 

 fences, etc., should be destroyed by burning or otherwise. 



B. — The vines should be cleaned as directed in section A. 

 If sheep cannot be procured, the leaves should be raked in 

 rows between the vines, that the vine-hoppers may lodge in 

 them. When the leaves are perfectly dry, apply fire to the 

 rows in places not more than eight or ten feet apart. Before 

 lighting the fires the vines should be jarred, and the vine-hop- 

 pers around tlieni drove into tlie dry leaves. Tliis method is 

 very effective.
