(Read, 23rd April, 1892.) 
At a meeting of the Canadian Institute, held April 4th, 1891, the 
following resolution was passed, on motion of the writer seconded by 
Mr. A. Macdougall: 
“That before any further steps be taken to promote the construction 
of a ‘Trunk Sewer,’ it is necessary that more definite, and precise inform- 
ation be obtained regarding the currents of the lake between the mouth 
of the Humber, and the south side of the Island and Victoria Park.” 
“That the City Council be requested to take a series of Float Observa- 
tions for a period of at least three months, extending through the 
summer and a portion of the fall—say from July till October—with 
temperature observations of the water at various depths, and readings of 
the velocity and direction of the wind, taken on the lake at the same 
time the floats are put in; these floats to be placed in deep water, com- 
mencing at thirty, feet in depth, and extending to sixty feet, or even 
deeper.” 
“That the co-operation of the Provincial Board of Health, and the 
Board of Trade be enlisted; and that a copy of this resolution be sent to 
each of the boards and to the City Council; and that a delegation con- 
sisting of Professor Carpmael, Dr. Canniff, Mr. A. Harvey and the 
Mover and Seconder be appointed to bring the matter before the above 
named corporate bodies.” 
In pursuance of the above resolution the matter was brought to the 
attention of the Boards of Health and Trade respectively, and unani- 
mously endorsed by them. Also a committee was nominated by each 
body to co-operate with the committee from this Institute to bring the 
matter before the City Council. Mayor E. F. Clarke arranged for a 
meeting with the City Engineer, W. T. Jennings, at which the subject 
was duly discussed, with the result that the engineering department under- 
took, with the assistance of the departments under Professor Carpmael 
and Dr. Bryce, to carry out the investigations referred to, the former to 
supply data from the Observatory in regard to the direction and velocity
