260* Insects Injurious to Vegetation. [Oct., 



Y., also, the fields suffered some, particularly those having a sandy 

 soil, and that were early sown. On the west end of Long Island, 

 its ravages w^ere also bad, many farmers not having more than 

 half a crop. Both in the eastern and western sections of Pennsyl- 

 vania, the fly lessened the produce of this year. In Bucks coun- 

 ty it was particularly destructive. One person states, in the month 

 of June, that where he had expected to gather 1,200 bushels or 

 more, he could not now hope for 300. Though it is noticed on 

 both shores of the state of Maryland, the injury done by it here 

 appears to have been but slight. 



In 1845, through those districts of Michigan, Indiana, and Il- 

 linois, where it committed such havoc the last year, it is said by dif- 

 lerent persons to have wholly disappeared. The Prairie Farmer 

 however, states that it was still present, doing more or less injury 

 all over the state of Illinois. Ohio sustained but little injury. It 

 is not noticed north of Maryland, in the central parts of which 

 state it is reported that on nearly all the light lands the Hessian 

 fly made serious ravages, and in many instances rendered the crops 

 totally worthless. In Georgia, moreover, its ravages in the coun- 

 ties around Milledgeville are said to have been dreadful: whole 

 fields were totally destroyed, and others yielded not more than a 

 fourth of an ordinary crop. 



We regret that we have not at hand the requisite information, 

 for tracing with equal precision the ravages of this insect during 

 the present year. From such notices as we have casually observed 

 in the public papers, we presume that through the country gen- 

 erally, it has been unusually numerous. In this vicinity, some 

 fields have produced less than a fourth of what they would have 

 done, but for the invasion of the fly last autumn, after an absence 

 of over forty years, and its great increase in the spring. On sandy 

 soils in Saratoga and the north-west parts of Rensselaer counties, 

 several fields -were observed early in July with the wheat stalks so 

 " few and far between," that no harvesting of them would be at- 

 tempted; whilst many others had been, at an earlier period of the 

 season, plowed up and occupied with spring crops. In the western 

 section of the state, it has also been quite destructive. The loss
