On the Continuous Growth of Wheat on the 
the corresponding months in 1870 ; but in the latter year the 
deficiency of rain commenced a month earlier, and continued 
later than in 18G8. The grass crops in consequence suffered 
much more in 1870 ; and, for a parallel, we must go back as 
far as 1844. As in the two preceding years (1868 and 1869), 
the reports of the cereal crops of the country were very variable, 
but for very opposite reasons in the years of heat and drought, 
1868 and 1870, as compared with 1869.

Although the yield of wheat in this exceedingly dry season 
was lower than in 1868, the weight of the grain was considerably 
higher, reaching in one experiment nearly 64 lbs. per bushel. 
The ravages of wireworm were very general throughout the 
country ; this considerably reduced the yield of the crop, which 
otherwise would have been a large one. 
Twenty-eighth Season, 1870-71. 
In October 1870 the changes of temperature were very 
frequent, giving however about the average for the month ; and 
there was a slight excess of rain. The first 19 days of November 
were for the most part cold, while the remainder was warm, 
but the average for the month was low, and there was a con-
