MESSRS. J. B. LA WES AND J. H. GILBERT ON THE RESULTS OF 
In Table III., the actual amounts of produce of hay per acre (first crops) on five 
selected plots, and the indices of those amounts. 
In Table IV., the monthly rainfall in inches (at Rothamsted). 
In Table V., the number of days in each month when the rainfall exceeded O'Ol inch. 
In Table VI., the monthly mean maximum temperature (at Greenwich). 
In Table VII., the monthly mean minimum temperature (at Greenwich). 
In Table VIII., the monthly mean temperature (at Greenwich). 
In Table IX., the monthly mean range of temperature (at Greenwich). 
And, in the respective tables, there are given, for each season, the total rainfall, the 
total number of days on which O’Ol inch, or more, fell, and the means for each item 
of temperature— 
1. For the total 12 months ; July to June inclusive. 
2. For four months—July, August, September, and October; 
3. For four months—November, December, January, and February ; 
4. For four months—March, April, May, and June ; 
5. For three months—April, May, and June ; 
6. For two months—April and May. 
It should be explained that, in Appendix-Table III., relating to produce, that of 
the same very characteristically differently manured plots is selected for illustration, as 
in the case of the consideration of the second crops ; in the left-hand columns of the 
table the actual amounts of produce of each plot are given, and in the right-hand 
columns the indices of these amounts—that is to say, for each plot the highest amount 
of produce in any one year of the 20 is set down as 1, the second highest amount as 
2, and so on. 
An examination of the columns of indices of produce will show that, with each of 
the five very different conditions of manuring, 1869 gave the highest amount of 
produce. On the other hand, 1870 gave, with two out of the five conditions of 
manuring the lowest produce, with two others the lowest but one ; but the remaining 
or nitrated plot was an exception, giving, in this year of drought, 1870, an abnormally 
high produce for the season—a fact which has been fully considered already (p. 334, 
et seq.). There can be no hesitation, therefore, in taking the season of 1869 as that 
of the highest productiveness of the 20, and that of 1870 (with the exception men¬ 
tioned) as one of the lowest productiveness ; the next in order in this respect being 
1874. It will be interesting to compare the produce in these two most contrasted 
seasons, 1869 and 1870, and also the characters of the seasons themselves. 
In Table XXIX. are given, for each of the selected plots, the average produce (of 
first crops) over the 20 years; the produce in 1869; the produce in 1870; the 
difference in amount over ( + ), or under (—), the average of the 20 years; and the 
deficiency in 1870 compared with 1869.
