or an average of 33 ft. for the four months.
Note. — It will be observed, that the averages here given are considerably less than for the last year (1831), as stated in the Journal for June. But on comparing the fall of rain for that, and the present year, as stated in the Meteorological Registers, I am inclined to think that the previous estimate for 1831 is not excessive, but defective. The small branch, or stream, when the river was at the highest, would have a depth of about 12 ft. and a breadth of about 300 ft., an addition so trifling to the main stream, that I have made no allowance for it.
