at or above 80; in 1852, 13; and in 1853, 11 
The extreme of cold was 25. There were three days in the year 
when the mercury fell to the freezing point, all in January. In 1851 
the thermometer fell to the freezing point on one day only. In 1852, 
35 was the lowest depression ; and in 1853, it did not sink below 40. 
warmest month in the year was July, then October, then Sep- 
ater. then August, he April, and June stands the sixth in order, 
and only two degrees above November. In neither of the three years 
preceding, was July the warmest month. In 1851 the warmest months 
occurred in the following order: August, October, September, June, 
July, April. fre 1852, September, July, August, June, October, No- 
vember. In 1853, October, September, i May, July, August. To 
the daily eae of the cold ocean wind in the summer is owing this 
great variation from the order of the cenit as to comparative temper- 
ature in other climates

“next March. In other years December sometimes takes the precedence 
of January. February, which “ ag Atlantic States is often the cold- 
est ‘op in the year, is not so

' cas supply, though only half the quantity that falls in the Atlantic 
States. In 1853, the quantity was 19-03 inches; in 1852, 25-60 inches ; 
and in 1851, only 15:12 inches. The old inhabitants tell of occasional 
seasons when scarcely any rain has fallen, and when the catile have 
perished from want. Such very dry seasons are said to recur at inter- 
vals of 8 or 10 years. 
The greatest amount of rain was in February—next comes January, 
next April, then March. This differs from the ordinary arrangement. 
Taking the last four years into view, December gives the most rain, 
and March comes next, while the intervening months are comparatively 
ry. In fact we have the early rains, beginning in November and con- 
tinuing through December into the early part of January, and ia later 
rains, ginning in March, and continuing at times through

No exhibition of Auroral light was observed in the year. Since my 
residence here, from Aug. 18 have seen the Aurora Borealis only 
on two occasions, once in January and once in February, in the year 
852. 
Earthquake shocks were distinctly felt on the mornings of the 9th of 
January and 21st of October.
