siderably, according to the size, supply, and demand, but at 

 Sfax a pair of them may cost, as circumstances rule, from 

 6d. to IS. ■^d. ; however, the preparatory maceration, by 

 beating on a stone slab or rock, required before drying 

 entails a small additional expense, and brings the extremes

 price must be added an export duty of 5j. id., and the 

 purchaser ought to be careful to receive his merchandise 

 from the seller during dry weather, as a damp day will

 carry out on a large scale an experiment, which appears to

Malta receives the largest share of the Tunisian polypi, 

 but they are only sent to that island for ultimate trans-

 is one of the few countries that competes with Tunis in
