lime had been applied.  The weather was extremely favourable until the wheat was going out of bloom, but it then changed, and the crop was beaten down by the rain, in some places so thoroughly that it never rose again; and from that time to the day it was reaped (21st August), there were not more than six fine warm days.  This cold and ungenial weather would, no doubt, materially affect both the quantity and quality of the crop,—­the sample only being just fair.  On thrashing out the crop, I find the result to be as follows:—­Where the guano and chemical manure were applied, but no lime, the yield was 49 1/5 bushels of 60 lbs. per statute acre; where the land was left unsubsoiled, it was 52 1/2 bushels; when guano alone was applied, it was 42 1/3 bushels; where the chemical manure alone was applied, it was 43 1/2 bushels; where the African guano was applied, it was 45 bushels; where the Peruvian was applied, it was 52 2/3 bushels; on the headlands, where three times the quantity of lime (or 3 1/2 tons per acre) was applied, it was nearly 62 bushels; and where six times the quantity of lime (or 7 tons to the acre), it was 49 2/3 bushels.  I give this last result as it was ascertained, but do not consider it conclusive, for the wheat plant on this headland looked quite as well as the other, until it went out of bloom, when from some unknown cause it was partially blighted; an irregular patch from a foot to a yard in width and extending almost from end to end of the headland becoming brown and parched, as if affected by lightning or some atmospheric visitation.  With the view of making these results a little clearer to the eye, I subjoin the following tabular statement of the produce per acre in the different parts of the field:—­

Bushels of 60 lbs. per statute acre.

Guano alone 42 1/3
Chemical manure alone 43 1/2
Guano and chemical manure, with 24 cwt.
lime to the acre, but land unsubsoiled 52 2/3
Guano and chemical manure, but no lime 49 1/5
African guano and lime 45
Peruvian " " 52 2/3
" " and 3 times as much lime 62
" " and 6 " " 49 2/3
Average crop throughout the field 50

It may be as well to observe, that the total expense of manure, and of its application to that portion of the field which produced sixty-two bushels per acre (including the guano and the additional quantity of lime used), was at the rate of 81s. per statute acre.  Deducting the cost of the nitrate of soda, the utility of which, under the circumstances, I am inclined to doubt, it would have been 63s. 6d.  I consider these to be very favourable results, and as offering strong inducements to continue the experiment.  I have accordingly had the land ploughed up and cleaned; and it was again sowed with wheat on the 9th inst.
