ture 6^° above the average, with only two days in which rain fell, 

 and produced very fine quality of grain. The inferior crops of 

 turnips obtained that year, notwithstanding the large total amount 

 of rain, arose from the almost entire absence of rain for thirty-one 

 successive days, twice during the season. From May 21st to 

 June 21st no rain fell, and from August 22nd to September 21st 

 there were only three days' rain, amounting to less than one- 

 tenth of an inch. 



The following table indicates the effect of climate upon the 

 quantity and quality of the produce of the unmanured plots of 

 the experimental wheat- field (during three seasons) ; the average 

 results of the variously manured plots are also given : —

The effect of the climate of these three seasons, as indicated 

 in this table, is quite in accordance with the general character of
