selling price was the same in both years, although minor changes 

 may be noted among the individual grades. In view of the strong 

 upward trend of commodity prices that has been in evidence 

 recently, the salt trade does not appear to be in a particularly 

 prosperous condition. 



The industry has experienced a tremendous expansion in the last 

 quarter of a century, in which time the production has increased 

 nearly fivefold. This is not entirely the result of the growth of the 

 salt trade, strictly speaking, within the territory tributary to New 

 York, although there has been a material gain in the trade; but is 

 due largely to the development of chemical industries that consume 

 salt, and especially of alkali or soda manufacture which has grown 

 to large proportions in recent years. It is estimated that the 

 amount of salt that is now converted into sodium compounds by 

 manufacturers within the State amounts to fully one-third of the 

 whole annual production of salt.
