The creation of this new branch of local industry is destined 

 to become a matter of very great general importance. Although 

 but two years have elapsed since the production of the first 

 bushel of salt in the Saginaw valley, there are now (Aug. 1st) 

 no less than 22 blocks of kettles in actual operation, turning out 

 1210 barrels of salt per day, or, making an allowance for the

Such is the strength and abundance of the brme and cheap- 

 ness of fuel, that a barrel of salt is made at a cost of 64 cents. 

 The cost of a barrel at Syracuse is at least 95 cents, so that Sag- 

 inaw salt would pay the''manufacturer 48 per cent of profit if 

 the price were put down to the prime cost of the article at Syra- 

 ciise. Moreover the quality of the article has proved so supe- 

 rior, that the market is actually clamorous for
