or with one-third added, for estimated damage, it is equal to 36
bushels per statute acre. From 2610 yards manured with No. 3,
there were 1,067 lbs. of wheat, and 211 stones 7 lbs. of straw, or
33 bushels to the statute acre, to which if we add one-fourth,
according to the estimate of damage, it will be equal to 41 1/4
bushels per acre. It will be observed that this portion yielded a
far greater weight of straw per acre than either of the others,
and from the sort of manure applied, it was expected that this
would be the case.

No. 1 yielded straw at the rate of 297 3/4 stones per acre.

Many people may feel inclined to say, that all these apparent data
are mere guesses, and that a crop may be made into anything one
likes, if they assume so much for damages; but, fortunately, it is
not all guess-work. I have stated previously that I covered a part
of each division with guano a fortnight after the application of
the manures in April, intending to see what advantage was obtained
by the use of it; but, owing to the depredations of the birds, the
portions of the first and second divisions manured with guano were
not kept separate from those which were left without guano; but
the third being later, and, therefore, not so much injured by
them, gave me an opportunity of ascertaining the effect. I
measured off a land which had been so manured, and reaped and
thrashed it out separately. From this land of 100 yards long and
10 feet wide (3,000 square feet), there was obtained 220 lbs. of
wheat, or 53 bushels of 60 lbs. per statute acre; and this was far
from being the best portion of the field. I don't mean that it was
not the best portion of the crop, but I mean that the soil was not
so good there as it was in other parts of the field; as I have
before stated, in the best part of the field the crop was spoiled
by being lodged by the rain, and subsequently attacked by rust.

I communicate this to you, in the hope that the publication of it
in your paper maybe the means of stimulating others to try the
same experiments. It is not too late yet to try for the next
year's crop, and I have no doubt that Mr. Blyth will be happy to
supply both material and information to any who may require them
from him. It is the duty of everyone to promote the advancement of
agriculture; and this is my contribution towards it. I ha
