into ear, it was allowed by all who saw it to be the best in the neighbourhood; but the heavy rains of July caused it to lodge in the best part of the field, and there it was attacked by rust, and the sample was very indifferent.  In addition to this drawback, there being very little wheat grown in the neighbourhood of the town, and this being much earlier than any of the other fields, was attacked by the birds as soon as the grain was formed in the ear.  Notwithstanding all the efforts made to prevent them, they continued feeding upon it until it was cut; and it is a very moderate estimate of the damage, to say that they destroyed one-fourth of the crop throughout the field.  That part of the field covered with manure (No. 1) being the earliest, suffered most.  There were patches of several square yards where there did not appear to be a single grain left; and wherever the birds took a grain from the middle of the ear, when in the milky state, the grains on each side of it appeared to grow no more, but shrivelled up in the ear.

I have little doubt that in this portion of the field one-third of the crop was destroyed.  All this seems to reduce the experiment to little more than guess-work; and it will, probably, be very difficult to persuade those who did not see the field when it was cut, to credit this report of the devastation made by the birds; even when they are told that Clitheroe is a town of 7,000 inhabitants, and probably as many sparrows, and that apparently they were all assembled to feed in this field; and they became so accustomed to the good living they found there, that even when our neighbours’ wheat was fit to eat, they continued to favour this field with their visits in preference to going elsewhere.  I estimate the damage on No. 1 at one-third, No. 2 at one-fourth, No. 3 at one-fifth; this was later than the others, and suffered more from rust than birds.

The following are the results:—­From 3,060 yards manured with No. 1, there were obtained 1,042 lbs. of wheat, or 27 1/2 bushels of 60 lbs. each to the statute acre; if we add one-half to this, as we assume that one-third was destroyed by the birds, it will give 41 1/4 bushels to the statute acre.  The weight of straw from this portion was 188 stones 5 lbs., 14 lbs. to the stone.  From 2,856 yards manured with No. 2, 962 lbs. of wheat were obtained, and 155 stones 9 lbs. of straw; this is equal to 27 1/4 bushels per acre, 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.
