lower joints of squash vines with earth to encourage the for- 

 mation of extra sets of roots at these places. 



The Squash Bug (Anasa tristis.) — This insect makes its 

 appearance the latter part of June or the first of July. The 

 females deposit their brownish-yellow eggs in small patches on 

 the under side of the leaves. These hatch into nymphs that suck 

 the sap of the leaves, often seriously injuring them. The full 

 grown bug is a little over one-half inch long and a rusty black 

 color above and yellowish beneath. They emit a disagreeable 

 odor when touched. They winter over in rubbish, under boards 

 or anywhere they can find protection. 



Remedies. — Hand picking in the morning and evening at 

 which times the bugs are somewhat torpid, is the most practical 

 remedy. Boards laid among the plants at night will be found to 

 have many bugs under them in the morning, and these may be 

 crushed or otherwise destroyed. Large numbers may be killed 

 in this way.
