The Grape Vine Leaf- Hopper. —Mr. Townsend, the entomolo- 

 gist of the New Mexico Agricultural Experiment Station, in 

 writing of this insect, often referred to as the "thrips," states: 

 "For some time after the hatching of the eggs, the minute 

 young are to be found mostly on the lower, older leaves. 

 Kerosene emulsion has been conclusively proved as the only 

 practical remedy for them. It should be diluted with fifteen 

 times its volume of cold water, and applied as soon as the 

 young hoppers appear, thoroughly reaching with the spray the 

 under side of all the leaves, especially the lower ones. If 

 deferred until they have acquired wings, it would be too late 

 to attempt to destroy them in this manner. Vineyards sprayed 

 only once the past season with the emulsion, as above di- 

 rected, showed thereafter not enough hoppers to do any injury 

 for the remainder of the season, the same vines having been 

 very plentifully infested before the application."— Nlh

It is strange, when this insect can be so easily destroyed, 

 that there should annually appear in the Vineyardist and other 

 papers so many complaints of severe injuries sustained from it. 



The Strawberry Weevil. — M. H. Beckwith, of the Dela- 

 ware Agricultural Experiment Station, in Bulletin No. 18, for 

 September, 1892, has written of this weevil, Anthonomus 

 musculus, which works in the buds and blossoms of the P erfe ^ 



blossom^the^vary or the rudimentary berry), thereby blast- 

 ing the berry. Kerosene emulsion and powdered hellebore 

 in water are recommended for use against it. 



A New Strawberry Slug.— Professor Herbert Osborn, of the 

 Iowa Experiment Station, reports successful experiments m 



in the early^part of June had extensively eaten the leaves 

 of a strawberry patch on the Station grounds. They were 

 thoroughly sprayed with one pound of London purple to 



, as shown by the presence of 1 

 le-half gallons of the spray ha 

 nearly one square rod, contair
