certainly conclude, that if we could find out a way of 
breeding Young Spiders in Rooms, they would fur- 
nifti us with a much greater quantity of Bags than Silk- 
Worms do : For I have always found, that of 7 or 800 
Young Spiders, there fcarce died one in the Year , and 
on the contrary, of a hundred Young Silk-Worms, not 
Forty liv’d to make their Bags. 
So great and confiderable a Difference as this, will 
undoubtedly move the Curiofity of fuch as are Lovers 
of Arts and Sciences, to endeavour to find out a way 
of Breeding thefe Infe&s. In hopes that fome lucky 
Chance, 01 my own Induftry, might favour me with fo 
lifeful a Secret, I made ufe of the following Expedient 
to furnifh my felf with a large quantity of thefe Bags, 
which I now propofe to the Curious, who may make 
the fame Tryal of it as my felf. 
I ordered to be brought to me all the large fhort-leg’d 
Spiders, that could be found in the Nlbnths of Augufi 
and September. Thefe I {hut up in Papers, and put them 
into Pots, and covered the Pots with a Paper prick’d 
full of Holes with a Pin, as were likewife the feverai 
Papers that were in it, that the Spiders might have Air. 
I fed them with Flies 5 and fome time after found, that 
the greateft part of them had made their Bags, of which 
thefe are fome. 
But I more eafily procured a great quantity of them, 
by promifing to pay the fame price for them by the 
Pound as for common Silk. This Advantage furnifhed 
me in a (hort time with a large quantity : And they af- 
fured me, they found no difficulty in getting them $ and 
that if they were permitted to go into every Houfe, 
where they faw thefe Spiders Bags in the Windows, they 
conld furnifti me with what I pleafed. So that we may 
eafily conclude, that there are Spiders Bags enough ?n 
the Kingdom to make large pieces of Work$ and that 
this New Silk which I propofe, is not fo fcarce or dear
