to me, I shall this fall give you an order for 20 or 30 tons more. I will only add that I consider every wheat grower who would study his own interest, will find it by trying similar experiments. T. POLLOCK BURGWYN." NOTE 1. In a subsequent conversation with Mr. Burgwyn, he stated a fact which makes this point much stronger. After ordering the guano, he left home, giving his farm manager orders to apply if to that particular piece of wheat as soon as it arrived. Owing to the fact that the seed was injured--that the land was in a very unfit condition from poverty and drouth to produce a crop of wheat, it had assumed such a miserable appearance before the arrival of the guano, that the manager wrote to Mr. B. his opinion of the utter folly of applying anything so expensive to a crop already struck with death. Not imagining how very unpromising was the prospect of success, Mr. B. immediately wrote to him to go ahead as directed. Before the application was completed he returned home, and his first impression was to stop the work at once and give up the field as lost; but on examining the effect upon that part where the guano was first applied, he found it had already infused new vigor into the plants, for they had put off their sickly yellow color, and taken on a vigorous green; and therefore he decided at once to go on, which as will be seen by the result, was a most valuable decision. NOTE 2. From personal knowledge of this very field, we are confident it would not have yielded without the guano, one half of seven bushels. It is a flat surface, clayey loam, and badly affected by winter rains, and such freezing and thawing as it had during the last severe winter. Besides it was a few years since, when it came into the possession of Mr. Burgwyn, one of those old worn out, skinned-to-death places, so common in that State, which all the deep plowing and good farming of that gentleman had not been able to restore, until he luckily hit upon guano; which notwithstanding the most unfavorable circumstances, has given him conclusive proof of its inestimable value. To say nothing of the ten bushels of wheat per acre, which we are confident he gained, the clover is worth more than the guano cost; and without it, one might almost as soon expect to grow clover upon Coney Island beach, as upon that field. This letter contains testimony of inestimable value. It comes from a gentleman of intelligence and careful observation, who is devoted to his profession of a farmer, and who has been one of the most successful renovators of worn out plantations in the south, and it comes very opportunely to give our work an appropriate FINALE.
