the Termites of Africa and other hot Climates , 
embarrafs one another ; and you are moft agreeably deceived 
when, after an apparent fcene of hurry and confufion, a regu- 
lar wall arifes, gradually filling up the chafm. While they are 
thus employed, almoft all the foldiers are retired quite out of 
fight, except here and there one, who haunters about among fix 
hundred or a thoufand of the labourers, but never touches the 
mortar either to lift or carry it ; one, in particular, places him- 
felf clofe to the wall they are building. This foldier will turn 
himfelf leifurely on all fides, and every now and then, at inter- 
vals of a minute or two, lift up his head, and with his forceps 
beat upon the building, and make the vibrating noife before 
mentioned; on which immediately a loud hifs, which appears 
to come from all the labourers, iffues from within fide the 
dome and all the fubterraneous caverns and paffages : that it 
does come from the labourers is very evident, for you will fee 
them all haften at every fuch fignal, redouble their pace, and 
work as faft again. 
As the moft interefting experiments become dull by repetition 
or continuance, fo the uniformity with which this bufinefs is 
carried on, though fo very wonderful, at laft fiitiates the mind. 
A renewal of the attack, however, inftantly changes the fcene, 
and gratifies our curiofity ftill more. At every ftroke we hear a 
loud hifs ; and on the firft the labourers run into the many pipes 
and galleries with which the building is perforated, which they 
do fo quickly that they feem to vanifh, for in a few feconds all 
are gone, and the foldiers rufh out as numerous and as vindictive 
as before (45). On finding no enemy they return again leifurely 
into

attack, it appears, that they but juft withdraw out of fight, to leave room for 
the labourers to proceed without interruption in repairing the breach, and in this
