394 On the Continuous Growth of Wheat on the 
March the rainfall was large — the first half of the month gene- 
rally warm, the latter half cold — and, upon the whole, the quarter 
had been very variable but colder than usual with many alterna- 
tions from frost to thaw. April and May were for the most part 
warm, with less than the average amount of rain ; but the end 
of May and nearly the whole of June were comparatively cold, 
with little rain. In July and August there was less rain than 
is usual in these months, but an excess in September. The 
day temperature generally ranged high in July, but about the 
average in August and September ; whilst the night tempera- 
ture was somewhat below the average in July, much below in 
August, and about the average in September. In June and 
July the dew point was below, and in August very much below 
the average. The degree of humidity of the air was in June 
low, in July about the average, and in August considerably below 
the average. 
Thus the winter was very variable, including a good deal of 
warm, but also much very cold and wintry weather, though with 
comparatively little rain. The spring, though changeable and 
wet at the beginning, was, upon the whole, warm and dry ; June 
was cold and dry, whilst the rest of the summer was hot in the 
day and cold at night, with very little rain, and in August 
especially a very dry atmosphere.
