one large lagune ; tlie islands connected and raised 

 by means of ■wickerwork, &c., which made a laby- 

 rinth, at every outlet of which certain traps were set. 

 The waters of the canal were turned into this lagune. 

 The fish from the sea enter through the traps into the 

 brackish water to spawn, but cannot return; and vast 

 quantities of eels, mullets, and other fish are thus 

 captured, a large stock always beiag kept up in the 

 lagune. 



The Lucrine Lake is another specimen of what can 

 be done with oysters, but the salt lake of Fusaro, 

 which I have previously referred to, is a more singular

 but what they can be withdrawn. From these stakes
