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 

 of low and high prices to 25^. or 50^. per cwt To the cost

 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 

 have proved successful, of preserving them either in oil or

 is one of the few countries that competes with Tunis in 

 supplying the Greek markets with polypi. In Greece they 

 are either sold, after being pickled, at from >\2 i6s. to
