ANALYSIS OF THE WATER BY DR EDWARDS. 
The specific gravity is 1.008. It is not aerated, nor is it alkaline. 
It contains (in 1000 parts) of saline and earthy chlorides, 11.9 grains, 
and of bromides and iodides, 0.4 grains. It contains, like some of its 
congeners, a small portion of strontium, and both bromide and iodide 
of magnesium. Of total solid saline matter, it contains per Imperial 
gallon of 70,000 giains, which I estimate to be combined as follows : 
Chlorides, 833 grains per gallon, combined as 
Chloride of Sodium 784-70 
Chloride of Potassium 10. 50 
Chloride of Stroutium l 4" 
Chloride of Calcium 14-7 
Chloride of Magnesium 21.70 
Bromide and Iodide of Magnesium 2.80 
Sulphate of Strontium 2 - IO 
Sulphate of Calcium ! 5-4 
Sulphate of Magnesium 19.60 
Silica and Oxide of Iron, etc 4-9 
Saline contents of one Imperial Gallon 877.80 
CHEMICAL ANALYSIS OF MANITOBA SOIL 
The Cause of its Great Fertility Explained. 
In the American Chemical Journal, Vol. XIV, No. 8, is a particu- 
larly interesting article by Mr. F. P. Dunnington, in which comparative 
analyses by Mr. T. C Whitlock are given of examples of (1) Soil, fur- 
nished by Dr. George M. Dawson, F.R.S., etc., from the prairie lands 
of Red River, taken at Rosser, about 15 miles west of Winnipeg, and 
(2) Tschernozem or Black Earth of Russia, from the district of P.ala- 
shoff, in the government of Saratoff. The specimens are described as 
so similar in appearance that thef cannot be . distinguished by the eye.
