the bald wlieat, refills the imprefTion made by the body of die 

 iiifecl, and in great meafure prevents the injury which arifes 

 from preventing the rife of the fap ; and for the fame reafon 

 is very probably more difagreeablc to the conftitution of the 

 infeft. During the laft year, I had an opportunity of making 

 one fair experiment, to determine whether any preference 

 ought to be given to any one of the different forts of wheat, 

 whofe ftraw is more firm and folid than the bald wheat. I 

 fowed three different forts of wheat, adjoining to each other, 

 and all at the fame time ; the white bearded, the yellow bearded, 

 and the great red-chaff wheat, whofe flraw is equally hard with 

 that of the bearded wheat ; of thefe three forts, the red-chafF 

 was by far the moft injured; and the yellow bearded which 

 lay adjoining to it, leafl of all. 



I SHALL now take the liberty of fuggefting a method of 

 deftroying the infe6l, which naturally occurred to my mind, on 

 obferving that it is not to be found in any other flate than that 

 af a chryfalis in the time of harveft, and that it remains in that 

 ftate in the Hubble for fome time afterward ; and that is, 

 to dejlroy the Jlubble of grain foon after harvefl. Whether this 

 would be befl effefted by burning or otherwife, and whether 

 the grain in this cafe ought not to be cut with the fickle rather 

 than mowed or cradled, and whether the cofts that would attend 

 it would not overbalance the advantage, are points to be taken 

 into confideration in determining whether any thing of this kind 

 would be feafible, and which I fliall not now pretend to difcufs j
