From January to June tlie river level was very uniform, at 
about Summer level, rarely exceeding three feet above Summer 
height. The principal variations were an excess of 4 to 8J feet 
at the end of February and beginning of March, and another 
excess of similar amount on the 15th, 16th, and 29th July. In 
the latter half of August and beginning of September the river 
again flowed very evenly at Summer level; but in October 
came the floods of the 29th to the 31st, at a maximum height 
of 12J feet. 
During November and December the river was very full, 
never once falling to Summer level, but reaching flood height 
on November 1st, 2nd, 14th, 15th, and 16th, and December 
24th, 25th, 30th, and 31st.
