126 A TREATISE ON THE CONNECTION OF 



• the charges attendant on the fire engine amount to 500I.' 

 a year, which is an abundant allowance where coal is 

 .cheap, and should the further interest on the sum en- 

 gaged in conveying the water to distant places amount 

 to 500I. more, the total expence for raising, conveying, 

 and serving 292 farms with sea water, would amount to 

 loool. per annum, or something less than 3I. los. for 33 

 tons of salt contained in the sea water which each farm 

 would receive. The prime cost of sea salt, exclusiveof duty, 

 could no where be less than il. in some places 3I. on an 

 average it should not be reckoned at less than il. los. per 

 -ton, which on 33 tons would amount to 49I. los. But, as 

 -to this must be added the present duty of lol. per ton, it 

 Avould cost the farmer 379I. los. for the quantity which, by 

 these means, he may receive for about 3I. los. Admitting, 

 however, that the expence of the fire engine, and of 

 conveying the water, were to be double the sum above 

 vStated, and that instead of 3I. los. it were to amount to 

 7I. a quantity of salt water containing one ton of salt 

 would, in this latter case, cost the farmer only 4s. 3d. or 

 at the rate of one penny farthing per bushel of salt of 561bs. 

 whilst the same quantity would now cost. 6s. Farmers,
