The above results would seem to indicate that up to an elevation of 7,500 feet, the temperature diminishes rather more than 1 degree Fahr. for every 300 feet of ascent or thereabouts; that this decrement is much leas in the summer than in the winter months; and I may add that it is less by day than by night. There is much discrepancy between the results obtained at greater or less elevations than 7000 feet; but a careful study of these, which I have arranged in every possible way, leads me to the conclusion that the proportion map be roughly indicated thus:—
1 degree=300 feet, for elevations from 1000 to 8000 feet. 1 degree=320 feet, for elevations from 8000 to 10,000 feet. 1 degree=350 feet, for elevations from 10,000 to 14,000 feet. 1 degree=400 feet, for elevations from 14,000 to 18,000 feet.
