The accompanying table exhibits the meteorological results obtained at the Observatory of
Bangalore for the past year, and, for the purpose of comparison, those of the previous four years
are also shown. The observations for 1877 are unavoidably submitted uncorrected.
They show an unusually high temperature and a moderate rainfall. The mean maximum
solar heat in vacuo was 150.1, being 2° higher than in 1876 and 7° higher than in 1875. The
mean humidity of the air was 1° higher than 1876. Rain fell on 91 days, and the total quantity
collected was 39.26 inches, an average fall being about 35 or 36 inches.
There was a heavy fall of 2 inches 64 cents. on the morning of the 1st of April, which
replenished the empty tanks and sensibly cooled the air ; but the south-west monsoon set in
late, and a large proportion of the early crops perished for want of seasonable rain. At a later
period of the year untimely rain produced a similar effect, so that the average crop in the
Bangalore Division was probably not more than a 6-anna one (?). At the French Rocks no
rain fell till September, and the total fall is said to have been deficient. The temperature was
unusually high throughout the year.
At Mysore the south-west monsoon is said to have failed, but the north-east monsoon set in
early and was a full one, and there has been a good crop.
In Mercara, the chief town of Coorg, the monsoon is described as an average one (112
inches), but the rain was more equable than in the previous year.
