occaflon to mention prefently. But the worms, in 
the room of the green cloathing they robbed thofe 
trees of, gave them one of white, fo entire, that it 
covered the whole bark, from the ground to the 
points of the flendercft twigs, and of fo pure and 
glofly a colour, that the whole tree fhewcd in the 
fun as if it were cafed in burnifhed fiver. The web 
was fo flrong, that if one difengaged it from the 
tree, near the root, one might have flipped it 
from the trunk, the branches, and the twigs, at 
one pull. As foon as the worms had covered all 
the Cornel-trees, they removed from thence, and 
covered all the Afh, Beech, Lime, Crab-trees, and 
even weeds, that grew near them, with the fame, 
but a thinner, kind of workmanfhip. 
Perhaps, my Lord, you will defire to know how 
they travelled from one tree to another. Many of 
them crawled along the ground, and over every 
thing in the way, fill leaving a thread behind, and 
difpatching a part of their bufihefs as they went to 
a more convenient furface to' finifh the reft on. 
But I really imagined fome of them took an eafier 
and more ingenious way. I found many of them 
hanging by their own threads from the m oft ex- 
tended branches of the treel While they were in 
this fituation, a gentle puff of wind might, by ex- 
citing a pendulous motion, waft them to the next 
tree. This fedms to bd the method, by which 
thofe very minute 1 fpideis, whofe threads are made 
viiible by the moifture adhering to them in a foggy 
morning, tranfport themfelves from one. bufh to 
another, altho' definite of wings, fometimes acrofs 
narrow paths, and even rivulets.
