 like nature. It will be impoffible in an account intended to be 

 fo concife as the prefent, to relate every minute particular ; 

 it was, however, fufficicntly obvious, both from the fhape of this 

 fpecies of infeft, and from every other attending circumftance, 

 that it could have no connexion with the infeft which had been 

 found on the wheat in the field, and this opinion was abundantly 

 confirmed by fucceeding ohfervations. In the fpring of the 

 year eighty-feven, the infeft in the field, and which proved to 

 be the real HefTian Fly, multiplied fo extremely fad on the 

 green wheat, that at the enfuing harveft many fields were almofl

 growing fuflfered as great injury as wheat had done before in

 wheat then moft generally in ufe among farmers in that part of

 in general, was in many places much injured; and what appeared 

 moft fingular was, that a piece of fummer barley, belong'ngto 

 the gendeman before alluded to, w^as about that time wholly

 harvefts, farmers began to turn their attention to raifing rye, 

 and that kind of grain was in general fown in the fall of the year 

 eighty-eight, except in fome few inftances where the bearded 

 wheat had been obtained ; and at the enfuing harveft in the
