INSECTS. 181 



tf the trees be scorched with a light flame, or washed, (Mr. 

 Deane says steeped,) in salt water, it will destroy these worms, 

 or prevent their entering the wood. 



The same author says, that in 1770, formidable armies of 

 worms overrun the county of Cumberland, about the middle of 

 July, and stripped the vegetables of their leaves, leaving only 

 the stems. They were extremely voracious, moved in appa- 

 rent haste and all in the same direction, crawling over houses, 

 &c. unless they found an entrance. Other paits of the eastern 

 states have since experienced their ravages. 



The best security found against them was to stop their course 

 by trenches, having their sides leaning over, out of which they 

 could not climb, after they had got into them. 



Hesssian fly. As the ravages of this insect are confined 

 to wheat, it is described, together with the remedy, ia the es- 

 say on wheat. 



Maggots. Injurious to the roots of cabbages, and to tur- 

 nips and radishes. Let the ground have a previous manuring 

 with salt, which it is believed will be effectual ; if not, let some 

 brine, about as strong as sea water, be sprinkled once only a- 

 bout the plants, for if repeated it will probably be found hurtful 

 to them. Or, perhaps, a better way is to apply a weak brine 

 more than once, and that just after a rain. 



Yellow striped b^g. This insect commits its ravages on 

 the young plants of cucumbers, squashes, melons, pumpkins, 

 &c. while in the seed leaf. 



Water, made bitter by bruising tansy in it, and sprinkled o- 

 ver the plants, will keep off this insect; but this must be fre- 

 quently repeated, particularly after rains. Green eider leaves 

 are also very useful, either laid near the plants, or steeped in 

 water and sprinkled on the plants. Soot, also, is very good, 

 sprinkled on the plants while the dew is on, but must be repeat- 

 ed after every rain. Gypsum and ashes are also good for this 

 purpose, sprinkled over the plants when the dew is on. Most, 

 er all of these applications, to become efficacious must be re- 

 peated, with persevering diligence. 



Turnip fly. This eats the seed of the leaves of the young 

 turnip plants, and thus destroys them. One remedy is, to sow 

 the grouad thiekly, partly with old and partly with new seed,
