between the dead water of the harbour and the water mov- 
ing down the lake. The water at this point is not so clear 
as that nearer shore, and has nothing to recommend it 
above the present city supply. 
The problem of an abundant supply of pure water is thus 
easy to solve. Fortunately, Kingston is so _ situated 
that the pumping station, near the centre of the water 
front, is only some 2,500 or 3,000 feet from the inexhausti- 
ble supply afforded by the unpolluted waters of Lake 
Ontario. The only doubtful point is the effect of the great 
numbers of dead fish which are seen floating in the lake 
and river at a certain season of the year, This point could 
be easily settled by analysis. 
TEMPERATURE. 
On July 15th, 1891, some observations of temperatures 
were made by Mr. Hewitt and myself. A_ half-gallon 
corked bottle was lowered to the required depth and 
allowed to remain for a few minutes. The cork was pulled 
out by means of a cord attached to it, and about five 
minutes after bubbles had ceased to come up the bottle was 
quickly drawn to the surface and the temperature of the 
water taken. The thermometer used was one made by 
Negretti & Zambra, graduated in tenths of adegree. The 
temperatures were taken at the points C, Band A, and 
an intermediate point.
