round, which was true of a large part of the drainage area is not 
in the latter sentence, but is implied by the connection. The 
floods also of 1880, 1881, 1882, 50 to 58 feet in height, occurred 
in February; and 19 out of the 27 between 1858 and 1884 were 
within the four months, December, January, February and March. 
Facts bearing on this subject are given by the writer in his 
paper of 1882, on the “ Flood of the Connecticut River from the 
melting of the Quaternary Glacier.”* It is there deduced from 
the tables of precipitation kept at different points in the Connec- 
ticut valley, and from the amount of discharge of the river as 
pi 
soil. 
In 1874, when the discharge of the Connecticut was so great, the 
two months of largest discharge were January (135,491 millions 
ini 
sources of the Connecticut, was 4-02 inches, and for May, 3°81 
inches; yet in April with a mean precipitation of 4:49 inches, the

precipitation of 3°74 inches, the discharge was only 55,018 mill- 
o 
ions. April is usually a month of frozen ground over the northern — 
half of the valley, but not always to so great an extent. Again, 
in February, the discharge amounted to 96,674 millions (half 
more than in April and two-thirds that of January), although 
the mean precipitation for the valley in that month was only 1°93 
inches, showing that thawing was the chief cause, not the precip 
tation of that month. 
urther, in 1877 (the year of minimum flood), during the 
month of October—too early for frozen ground except on the 
high mountain tops and yet always a cool month—the amount of 
discharge of the river was only 31,772 millions of cubic feet, 
although the mean precipitation in the valley for the month was 
5°45 inches, which is greater by one third than in the months of 
greatest discharge in 1874,
