Fig. 1. —Upper Row: Large, Full-Sized, Healthy Hops. Lower Row: Small, 
Rough Hops, Showing Loss in Weight Due to the Red Spider. (Original.) 
Fig. 2.— Leaf of Hop, the Left Half of which was Sprayed with Lime- 
Sulphur and Flour Paste, and the Right Half with Lime-Sulphur

Note that the spray is uniformly distributed on the left half of the leaf; on the right half, 
however, it is collected in separate drops or patches, owing to the pubescence of the leaf.
