the series, whether by autumn or by spring sowing. In 187!', 
on the other hand, autumn sowing gave not only much less than 
spring sowing, but much less than in any of the other cases of 
either autumn or spring sowing. 
The following summaries bring prominently into contrast 
the produce of the two seasons, and the characters of the seasons 
themselves : —

Thus, in 1874, the autumn-sown ammonia-salts gave 39|bushels 
of corn and 4645 lbs. of straw ; and 10^ bushels more corn, and 
1869 lbs. more straw, than the spring-sown ammonia. With 
this heavy crop by autumn-sown ammonia, and much heavier 
than by the spring sown, there were only 7-05 inches of rain from 
the date of autumn sowing to that of spring sowing, and only 
2-89 inches of drainage through the 60-inch drain-gauge, during 
the same period. Then again, from the date of spring sowing to 
the end of June, there were only 5*12 inches of rain, and only 
0-25 inch of drainage through the 60 inches of uncropped soil. 
It would appear that the small amount of winter rain was suffi- 
cient to aid the conversion of much of the ammonia of the manure
