We have already written so fully upon the crop of 1879 in the 
Journal of this Society, vol. xvi. part i. 1880, that it will be suffi- 
cient to say here, that it was not only by far the worst crop grown 
during the forty years of our experiments, but it was certainly 
the worst grown in Great Britain since the year 1816. It will 
be enough to give one instance. On plot 7 the yield in 1863 
was 53 bushels per acre, while the same manure in 1879 was 
only competent to produce 16 bushels! It was estimated that 
the crop of the country was not much more than half an average 
one. 
Thirty-seventh Season, 1879-80. 
October was both cold and sunless, but at the same time 
exceedingly dry. November and December were also both 
cold and dry ; there is, in fact, no record of so cold a December 
since the beginning of the century. January was exceedingly 
cold and dry, hardly any rain falling from the beginning to the 
end of the month. February was warm, with a rainfall over the 
average. March was warm during the first half of the month, 
and afterwards cold, but very dry. April was alternately cold 
and warm, the latter predominating ; the rainfall was slightly
