there is a fecond canal, upon which the town called 
• Thimida was formerly built : this canal is about a 
quarter of a league long, and communicates with a 
fecond pond fomething lefs than the former. I can- 
not find a reafon why (according to Monf. De Lille, 
in the chart for the confideration of the council), 
this-pond fhould be called Lacus Dulcis ; for they 
both are fait water notwithftanding, and nourifh a 
great quantity of fea-filh j fuch, among others, as the 
mullet, the roe of which they call, when it is dry, by 
the name of fcoutarque *. 
I had heard, that there were confiderable currents 
in thefe lakes j and when we arrived at Bizerty, I 
law the waters run out of the lake with fo extraor- 
dinary a rapidity, that I took it for a river : but, upon 
recollecting what was told me, I obierved, that the 
wind was then at E. N. E. that the waters ran out 
for eight days with this wind ; and the lake funk a 
foot and half by the obfervations I made on one of 
the piers of the bridge upon this canal. The wind 
then changed, and came about to the weft, and the 
water returned with the fame rapidity that it had 
run out before. I even perceived on the bank, or 
fence, made by the reeds, that the waters of the 
fea were four inches higher than thofe of the lake ; 
and rofe while the wefterly wind blew. Some days 
after the winds lhifted ; and I faw ,on the fame

Tunis ; and fays, it is famous for affording a fine profpett; receiving 
no fmall beauty from the many flocks of the Flamant, or Phccni- 
copterus, that frequent it : and that it is no lefs famous for its large 
Sweet Mullets j the roe of thefe dried is a delicacy, and called 
BotargO.
