to the cold air and the birds or fowls. This followed by 

 deep plowing will prevent other cocoons that may escape 

 from reaching the surface in the form of the moths. Burn 

 all dead vines and squash rubbish after the squashes are 

 gathered. During the growing season keep the plants 

 vigorous and healthy. (Chittenden.) 



The Squash Bug (Anasa tristis, DeG.). — This insect is 

 of a rusty black color above, and yellowish beneath; of a 

 foul, disgusting smell ; of quick motions. It eats the leaf 

 and stem, and at 

 length destroys the 

 stem. It lays its 

 dark - colored eggs 

 in patches upon the 

 under surface of 

 the leaf, to which 

 they adhere strong- 

 ly. As s o on as 

 hatched, the young 

 e n e m y in little 

 swarms commence 

 feeding upon the 

 leaf, upon its under 

 side, which soon 

 withers. They are quite timid, but may be found in the 

 cool of the day concealed under the leaves or clods of 

 earth, and should be sought for while the vines are young, 

 daily, in the morning, and crushed before they become 

 numerous. 



The Turnip Flea Beetle (Phyllotreta vittata, Fab.). — 

 This is a small, hard-shelled insect, of a smooth, shining, 

 brassy, or greenish-black color, about an eighth of an 

 inch in length. There are two yellow stripes down the 

 wing cases. The hinder legs are formed for leaping. It 

 attacks the turnip, and other plants of the same family,
