 Strict attention must be paid to the early removal of any decayed 

 berries, and also to the replenishing of the bottles with water as 

 often as may be necessary. An even temperature of 4odeg. to 



45deg., with as dry an. atmo- 

 sphere as possible, will be suit- 

 able for keeping the Grapes 

 plump and sound. Any great 

 fluctuations are always bad for 

 the keeping of this fruit. 



Of the pests affecting 

 the Grape the 

 most to be 

 dreaded is the

 the use

 that are practically proof against 

 the attacks of the insects, which 

 are near relatives of the Aphides. 

 As in the case of the American 

 Blight there are both root- and 

 leaf-feeders, the latter being dis- 

 tinguished by the tubercles found 

 upon the adults. The former are 

 the most difficult to deal with, 

 as they are out of the reach of 

 most insecticides. The galls due 

 to their attacks on both roots and 

 foliage are shown at Fig. 659. 

 Kerosene emulsion has given ex- 

 cellent results in America : it has 

 been used for both foliage and

 water should be added, and the mixture is best
