If we compute from Table XLVI average annual values for each10-year period from 1820 to 1900, we find a fairly close agreement, show-ing a strong tendency to return to a certain normal value in spite ofgreat fluctuations in individual years. The most conspicuous departureis the great deficiency recorded from 1861 to 1870. DEPARTURES OF TEN-YEAR AVERAGES FROM THE NORMAL FOR 87 YEARS. Decades.
