lower layer turns black and drops off, while the ground 

 under the plant appears covered with the casts or 

 bodies of the insects as with a white powder. When in 

 this condition the plants arc in a very bad way. 



Considering the circumstances under which this in- 

 sect appears, usually in a very dry season, I hold that it 

 is rather the product than the cause of disease, as with 

 the bark louse on our apple trees ; as a remedy I advo- 

 cate sprinkling the plants with air-s'aked lime, watering 

 if possible, and a frequent and thorough stirring of the 

 soil with the cultivator and hoc. The better the oppor- 

 tunities the cabbage have to develop themselves through 

 high manuring, sufficient moisture, good drainage, and 

 thorough cultivation, the less liable they arc to be 

 " lousy." As the season advances there will sometimes 

 he found patches eaten out of the leaves, leaving nothing 

 hut the skeleton of leaf veins ; an examination will 

 show a band of caterpillars of a light green color at 

 work, who feed in a compact mass, oftentimes a square, 

 with as much regularity as though under the best of 

 military discipline. The readiest way to dispose of 

 them is to break off the leaf and crush them under foot. 

 The common large red caterpillar occasionally preys on 

 the plants, eating large holes in the leaves especially 

 about the head. When the cabbage plot is bordered by 

 grass land, in seasons when grasshoppers arc plenty, 

 they will frequently destroy the outer rows, puncturing 

 the leaves with small holes and feeding on them until 

 little besides their skeletons remain. In isolated loca- 

 tions rabbits and other vegetable feeders sometimes 

 commit depredations. The snare and the shot gun arc 

 the remedy for these.
