picked over, for the season was so unfavourable for cleaning the land (from the great quantity of rain that fell) that I was almost induced to abandon the experiment.  Previously to sowing the seed, one-fourth of the field was manured with a compost of night-soil and coal-ashes, at the rate of forty tons to the customary acre (7840 yards); the remaining three-fourths having the seed put in without any manure whatever.  The winter was very unfavourable for the plants in our cold wet soil, and in the unmanured part of the field many of them perished, and those that survived made very little progress, from having no stimulus at the roots.  Thinking it desirable to apply my experimental manures in moist weather, I waited until the 6th May, when I treated that part of the field which had not been manured (three-fourths of the whole) in the following manner.  I applied guano to one-fourth, at the rate of two hundredweight to the statute acre, and the same weight of nitrate of soda over another fourth, leaving one-fourth entirely without manure.  The wheat manured with the guano and nitrate of soda grew vigorously, and the ears, more particularly in the part manured with guano, were the finest I had ever seen, but when it came to ripen it shrivelled in the ear, and the sample was very indifferent; the soil being evidently deficient in some property necessary for perfecting the grain.  The crop also suffered much from the depredations of the birds.

The portion manured with night-soil produced
     to the statute acre 32 bushels of 60 lbs. each.

I give these details to show that the land was in an exhausted state previous to the commencement of the experiment I am now about to detail.  After the crop of 1842 was reaped, the land was immediately ploughed up, and the season being very favourable, it was tolerably well cleaned, and the seed was sown (without any manure) about the first week in October.  After the wheat came up, it was manured with a dusting of one hundredweight of guano, over the entire field (about one acre, three roods), to keep the plants alive through the winter.  In the spring, being divided into three portions, it was manured with the same number of experimental manures, which were furnished to me by Mr. Blyth, of Church, near Accrington, who also analyzed the soil and subsoil for me.  These manures were applied about the 10th of April, and the experiment was still further varied by covering a portion of each division with guano a fortnight afterwards, at the rate of two hundredweight to the acre, but all the manure applied to the crop, including the hundredweight of guano put on in the autumn, did not exceed 6 1/2 hundredweight.  The crop, which was a very thin one in the spring, improved so much by the application of these manures, that when it came
