The above table shows the amount and per cent of the total heat absorbed by the 
surface which is left in each lo-meter stratum of the lakes studied. The rapidity 
with which the heat declines is evident, and shows how hard the wind finds the task of 
overcoming the thermal resistance. A single illustration shows this in a striking manner. 
We may allow 1,000 calories per square centimeter as a full (not a mean) supply to 
the surface for a single summer day. We find in the various major lakes that this 
amount was distributed in 1910 to the water below a depth of 35 to 60 meters, and below 
30 to 50 meters in 1911. Thus the work of the entire season was necessary to carry to
