Tab. III. Fig. 2. • After one Cell is formed, they 
flop it up, and join another to its End, and then add 
another to that j which makes thefe wrought Clay 
Fabrics longer than the plain ones. 
Their Method of Working is much alike, and it 
is very diverting to fee them at it : Their Art and Con- 
trivance is wonderful ; and, as if it was given to 
chear them at their Labours, they make a very par- 
ticular muftcal Noife, the Sound of which may be 
heard at ten Yards Diftance. 
Their Manner of Working is, to moiften Clay, 
and temper it up into a little Lump, of the Size of 
Swan-fhor. This they carry to build with; they 
begin firft at the upper End of the Cell, and work 
downwards, until it is long enough to contain the 
Nymph or Chryjalis : After they have fpread out the 
little Lump in a proper Manner to form their little 
Fabric, they fet up their mufical Notes, and return 
to temper and work up more Clay for the next 
Courfe. Thus they continue alternately ftnging and 
working, until a Cell is finifhed ; which is made 
delicately fmooth wirhinfide ; then, at the further 
End of each Cell, they lay an Egg; after this, by 
furprifing Inftind, they go and catch Spiders, and 
cram the Cell full of them: But it is further won- 
derful to obferve, that they only in fome manner 
difable the Spiders, but not kill them ; which is to 
anfwer two Purpofesj firft, that they fhould not 
crawl away before the Cell is finifhed ; and next, 
that they may be preferved alive and frefh until ths 
Egg hatches, which is foom
