are : Rabbit Isd, Landrie Lake and River Tillard, the water from the 

 two latter places being chalybeate in character, while that from Rabbit 

 Island is highly charged with sulphur, which is deposited in the pond 

 into which it flows.

Banff, Alberta. — The waters of the Thermal springs at this 

 place have of late years commanded considerable attention, though 

 more particularly since the inaugaration of the Banff National Park and 

 the erection by the Canadian Pacific Ry., of their large sanitarium. 

 The curative properties ot the waters are too well known to require 

 further mention here. 



In the Geol. Surv. Rep. Ill, part II, 1887-88, p. 21 T, is an analysis 

 of a specimen collected by Mr. R. G. McConnell :

"The water was examined for lithia, iodine, and bromine, but no 

 other constituents. Distinct evidence was obtained of the presence of 

 lithia; iodine and bromine were not detected; this does not necessarily 

 imply that they were not present in the water, in as much as the 

 amount of water operated on was far less than would be required for 

 the detection of traces, or even very small quantities of these substances. 

 Geol. Surv. Rep. Vol III., 1887-88, part II, p. 22 T. 



The physical features most apparent were : colourless ; devoid of 

 any marked taste ; odourless ; reaction faintly alkaline ; specific gravity 

 of filtered water, at 15. 5*^ €. = 1000-99. Mr. McConnell in referring to 

 this spring says : — "The water has a temperature of 111° F. in summer, 

 but it is said to rise to 119° F. in winter. The lower temperature in 

 summer may be caused by the water being affected to some extent by 

 the surface drainage, which is more active at that season. It has a 

 large flow, and is forced up in large quantities through an aperature 

 several inches in diameter" * * Ibid, page 21 T.
