the charges attendant on the fire engine amount to 500!. 

 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 500!. more, the total expence for raising, conveying,

 loool. per annum, or something less than 3!. xos. for 33 

 tons of salt contained in the sea water which each farm

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

 would cost the farmer 379!. IDS. for the quantity v, hich, by 

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

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