NOTES UPON FLOODS IN LAKE GEORGE. 243 
lake, oe the first few days of January, 1887, Mr. Glover 
rried these measures for me, and reports as follows: 
= Jan abies “Oth, 1887, I have taken the levels from the top of the 
south terminal of the base line near Mr. Powell’s house to the 
water, and find fe difference is 59°84 feet. I have taken the sound- 
ings over the e places that Mr. Chisholm sounded, and find 
the deepest sane is 8 feet 2 inches, the other particulars of sound- 
ing will be found on the plan of the lake. I find that at the south 
end of the lake the rise in 60 chains is 10°28 feet, that is, from 
10-28 feet in 60 chains; but this rate is not maintained in the 
water, for there I found that from the edge of the water toa 
distance of 1 mile in the fall was only 4 fee 
At the north end of the lake the change of level is not so rapid 
ee from the water (present edge) 1 mile towards the high-water 
ark there is a rise of 7°07 feet, and in 1 mile the other way ; 
that j is, into the water are is a fall of only 1°80 feet. I carried 
the levels also from the water up over the first gravel ridge into 
the wet lagoon, i.e., the gravel ridge that Mr. Beit cut through in 
order to drain the lagoon. I found the top of the gravel Tidge 
- 32°90 feet above the water, and the bed of the lagoon is 16-08 feet 
above the water, and therefore 16-82 feet below the gravel ridge. 
I have sounded the la ke over the lines on Mr. Chisholm’s rough 
makes it 21 feet, and the deepest place is in the middle of the 
lake 9 feet 1 inch.” 
» “T find the railway marked tree at the end of the water at the 
south end is 62, and at the north end 32, the lake is therefore 
—_ 15 miles lon “if 
““T may mention that from the present water to high-water mark 
at the south end is 73 chains, and at the north end 100 chains.” 
The details of these levels will be found on the map and on the 
section of the lake. 
It will be seen in the section that the lake was sounded for 1 mile 
at each end, and for a short distance in the middle, Sas it has 
een assumed that the bottom is fairly idtahin’ in slo 
the levels Mr. Glover started from the ene of the 
on the south terminal stone of the base line, but the base line 
levels were to the mark under the cap, 1.e., 0 75 feet below Mr. 
Glover’s point. e may now see how w these connections come ont,
