iii the Beginning of the enfuing Spring yielded a 
yellowifli Juice. 
In the Spring of 1748. certain little blackifh Worms 
were feen lying in the Fields and among the Bufhes, 
flicking together, and colle&cd in Clufters, not un- 
like the Hillocks of Moles or Ants. As no body 
knew what they were, fo there was little or no No- 
tice taken of them ; and in May they were cover'd 
by the fhooting of the Corn fown in the Winter. 
But the fubfequent June difeover’d what thofe 
Worms were 5 for then, as the Com fown in the 
Spring was pretty high, thefe Creatures began to fpread 
over the Fields, and become deftrutiive to the Vege- 
tables by their Numbers. Then at length the Coun- 
try People, who had flighted the timely Warning 
given them, began to repent of their Negligence ; 
for, as thefe Infe&s were now difperfed all over the 
Fields, they could not be extirpated without injuring 
the Corn. 
At that time they differ little or nothing from our 
common Grafshoppers; having their Head, Sides, and 
Back of a dark Colour, with a yellow Belly, and the 
reft of a reddifh Hue. About the middle of June, 
according as they were hatch’d fooner or later, they 
were generally a Finger’s Length, or .fomevvhat 
longer, but their Shape and Colour ftill continued. 
Towards the End of June they caft off their out- 
ward Covering $ and then it plainly appear’d that 
they had Wings, very like the Wings of Bees, but 
as yet unripe and unexpanded ; and then their Body 
was very tender, and of a yellowifh Green : Then, 
in order to render themfelves fit for flying, they 
gradually unfolded their Wings with their hinder 
Feet,
