To this we beg leave to add from our own knowledge of this land, which is situated on the Roanoke river 6 or 7 miles below Halifax, that it was before being improved by Mr. Burgwyn, about as unpromising a tract as can be found upon all the "cottoned to death," poor old fields of that sadly abused State. In the condition it was when we first saw it, while undergoing the operation of putting a four horse plow through the broom straw and old field pines, notwithstanding our strong faith in the ability of such men as the Messrs. Burgwyns to redeem such land from its condition of utter and apparently hopeless barrenness, we must own, that if Mr. B. had made the assertion while we were riding over this very tract, that within two years he would reap a remunerating crop of wheat from the barren waste, and coat the ground with a carpet of luxuriant grass, we should have told him the day of miracles had passed away. But we had not then seen as much as we have since of the miraculous power of Peruvian guano.
We might continue to cite hundreds of similar cases but propose to pass over into Maryland, and after showing its application there has produced equally beneficial results, travel northward, calling here and there a witness as we proceed. Among others, we may call to the stand in Maryland, will be the editor of the American Farmer, whose testimony we consider almost invaluable, having devoted much attention to the subject, and to whom, and his able correspondents, we desire to award full credit, in this general manner, to save repetition, for much of the information we shall give the readers of several of the succeeding pages. The testimony of witnesses of such high standing, cannot be too highly estimated by those who are anxious to learn how to renovate their worn out farms, or make the rich ones richer.
_Effects of guano upon the crop to which it is applied._--Edward Stabler, in the American Farmer, thus speaks of an experiment he made in 1845, soon after the introduction of guano to any extent into this country.
"In a field of some 10 acres, one acre was selected near the middle, and extending through the field, so as to embrace any difference of soil, should there be any. On this acre 200 lbs. of Peruvian guano, at a cost of about $5 was sown with the wheat. Adjoining the guano on one side, was manure from the barn yard, at the rate of 25 cart loads to the acre; and on the opposite side (separated by an open drain the whole distance;) ground bones were applied on the balance of the field, at a cost of $6 to the acre; the field equally limed two years preceding. There was no material difference in the time or manner of seeding; except that the manure was lightly cross-ploughed in, and the guano and bones harrowed in with the wheat.
