Mr. Nelson thinks the yield of wheat will average in that neighborhood, an increase of 16 bushels for 200 lbs. of Peruvian guano.

H. Chandler, Westmoreland Court House, bought a farm at a price for the whole below the cost of the mansion house alone, because the land was so utterly and hopelessly worn out, as to be past the ability of supporting those engaged in its tillage. When we saw it, we should have been willing to insure the growing crop of wheat at 20 bushels, the result of 210 lbs. of Peruvian guano to the acre; while the clover upon the stubble of the previous year could not be excelled in point of luxuriousness upon the richest field in the State of New York, where the land was valued at $100 an acre.

Mr. Chandler first commenced with 250 lbs. African guano, measuring 3½ bushels, to the acre, upon which he sowed one bushel of wheat. The result 17 bushels to the acre upon land which only gave 5½ bushels in any previous crop. Cost of guano $5; profit, $6 50. The next year he gained an increase of 12 bushels to the acre over previous years, by the use of 250 lbs of Patagonian guano; while the clover, Mr. Chandler thinks, worth more than the whole cost of the application. A still better result was produced last year from 210 lbs. of Peruvian. The soil is a yellow clayey loam, which in its unimproved condition looks about as unpromising for a crop, as the middle of a hard beaten road.

Mr. C. tried guano upon river bottom land, but the improvement was not so remarkable.

We were assured by Mr. C., that many persons who had long been accustomed to look upon the hopeless barrenness of this land, were wont to stop as they rode past this field of clover, and look at it with utter astonishment. Some could not be satisfied with looking, but would drive to the house to inquire what magical power had been used to produce such a strange metamorphosis in the appearance of the place. When assured it was all effected by guano, they went away—not satisfied—but unbelieving.

What tends much to increase the effect of this improvement, is the fact, that directly opposite lies another tract, still in its barren condition, lately purchased by Dr. Spence, a very enterprising gentleman, imbued with the spirit of improvement, which will soon be brought into the same condition, notwithstanding its unforbidding appearance.

Mr. S. B. Atwell who owns an adjoining farm, has been equally successful in the use of guano. Before using it, his wheat upon 20 acres was hardly sufficient to pay for harvesting. The first crop after using it, 400 bushels. He has also increased the crop of corn from 20 to 260 barrels by lime, guano and clover. In the meantime, the land has increased in value in about the same ratio.

In Lancaster County, we saw a field of wheat on the farm of Dr. Leland, sown upon corn ground, one part with 200 lbs. of Peruvian guano to the acre, the other with a full dressing of hog-pen manure, by the side of which the ground was seen in its natural barrenness, scarcely making a show of greenness; while the rank growth of the guanoed portion made as great a contrast with that manured upon the opposite side.

Guanoed wheat upon the farm of Col. Downing in the same county showed as great a contrast with land both limed and manured; while directly alongside of this luxuriant growth, the land was as destitute of vegetation as a brick pavement.

The effect of guano upon strawberries, Col. D. found to excel anything else ever tried.
