day to the same hour on the next;
lows passed this point on the 10th and
23d; highs on the 4th, goth and 3lst. In
the October report the following re-
mark was made: 1T will be interesting
to note whether seven successive
months of low barometer will be fol-
lowed by unusually heavy rains" The
report below will show whether this
was well founded.
Relative humidity, 1862; normal. 10;

absolute moisture, 6.63 grains to the Gu

was unusually low during the last
three days of the month.

at Kapiolani Park. 9.S3. Total rainfall
since January 1, 1896; normal, 300.
The artesian well level rose during
the month from 1886 feet above, mean
sea-level to 34.05. January l, 1901. it
stood at 34.00. 1t would seem that the
lowering of the wells has come to a
standstill, owing to the failure of the
high-level wells, and probably greater
economy on the part of those at a low
level. The average daily mean sea-
level for December was 1926 on the
scale, 1000 representing an assumed
annual mean. and 9.S2 the actual an
nual mean for nine years previous to
1901. The mean for 1901 has been 1917.
