HO REPORT OF THE 



baskets and drained. The article manufactured by this process 

 is white and beautiful. After standing some months, a slight 

 deliquescence is perceived, but not as great as rpoa most of 

 our commercial salt. Experiment shows it to be peifectly free 

 from gypsum; though, of course, rigorous analyses is requisite 

 to fully test its purity. I am not apprised of the results of ex- 

 periments on its preservative qualities. Two hundred and 

 thirty barrels have been manufactured. 



At the Indian Creek Co.'s works the evaporation is conducted 

 in large sheet iron pans. At Windsor's, both pans and kettles 

 .are employed. 



The salt business of the Saginaw valley was commenced by 

 the East Saginaw Salt Company, who bored a well about three- 

 fourths ol a mile north-east of ihe village on the bank of the 

 river. This well penetrated the saliferous beds between 464 

 and 627 feet, and ended at 669 feet. The strength of the wa- 

 ter at different depths was as follows: At 70 ft., 1°; at 102 ft, 

 2°; at 211 ft., 10°; at 293 ft, 14°, discharging 80 gallons per 

 minute of a temperature of 50° Fah, and rising 14 feet above 

 the surface; at 487 ft, 26°; at 516 it, 40^; at 531 ft, 44°; at 

 559 ft., 6,Q p j at 569 It, 6-4°; at 606 it, 86°, with a temperature of 

 54° Fah., and at 639 ft , 90°, or ten degrees short of saturation. 



A sample of this water at 64°, from the depth of 575 ft., was 



examined by Dr. Chilton, of New York, with the following 



result: 



Solid residuum in one wine pint, , 1 155 ^va^ 



Ghlorid of sodium (common salt,) 1014.57 " 



Specific gravity, 1.110 



A sample at 86°, from the depth of 617 ft, was examined by 



Dr. J G. Webb, of Utica, N. Y, with results as follows: 



Ghlorid of sodium in one wine pint, 1416 grs. 



Other chlorides 32 grs* 



Subsequently a more detailed analysis of the brine was made 

 by Dr. Webb, the results of which are given below: 



* There must be an error in this amount, as tins brine standing at 86° should have about 

 1800 gi-s. of solid matter to the pint.
