In nearly every year a dry period of longer or shorter duration occurs during August, September or October and is known locally as the " Indian ; An examination of the monthly records averaged in the above figures shows that this drop in the rainfall was distinct in about 35 out of the 53 years under consi- deration, the rainfall being below five inches four times in August, eight times in September and thirteen times in October.
