Same on the evening of the 23d, from 7 till 11 o'clock. The ice on the Missouri broke and commenced moving on the 29th February; but a few days after it blocked up and continued stationary until the 14th of the present month, when it began to move again; and on the 18th it was entirely open and clear of ice. In this register an extra column is added, containing the daily rise or fall of the river. The sign--denotes the fall of the water during the last twenty-four hours, and the sign + denotes its rise during the same length of time. When the register was commenced the river was three feet above the low-water mark, or its lowest stage in the winter. Therefore on the 25th, when it was highest this month, it was thirteen feet five inches above its lowest stage in the winter. {lxiv} _Meteorological Register_ {lxv} _for the Month of_ APRIL, 1820
