NOTE 1.--Yes, that is the word--_good luck_--it is all good luck. It is astonishing how many farmers there are in this country who will stand with their hands in their breeches pockets, fumbling idle dollars, while a neighbor expends his for guano, and produces a fine crop of wheat upon an old worn out buckwheat field; at which they stare in stupid wonder at the good luck of the thing. What a pity it had not been the good luck of such men to have been born with common sense enough to profit themselves by their neighbors good luck. NOTE 2.--It would be far better to sow the guano broadcast and plow it in, or scatter it in drills and turn a light furrow on it before planting. "_Hempstead, Aug.27, 1852._ SETH CHAPMAN, ESQ.--Dear Sir:--I believe I was the first person in Queens County using guano; having imported some from England in the ship Yorkshire, in 1842. This was from the Ichaboe Islands. I have since used nearly all the varieties, and consider the Peruvian the cheapest and best. In applying guano, I think by making a compost, the greatest benefit is derived; say one peck of plaster, one bushel of loam, two of saw dust, mixed up a month or six weeks before using. From 100 to 200 lbs. of guano is enough for a crop of oats or buckwheat. I have not found it to succeed with corn or potatoes; probably from being accompanied by a dry season. The best wheat I ever raised was from using 350 lbs. to the acre, composted. This was on a light soil, and returned 31 bushels to the acre, on seven acres, weighing 62 lbs. The grass was poor after it. As a top dresser, I have used 200 lbs. per acre, very early in the spring, on half a lot, which mowed more than half as much again as the part not dressed. One of my neighbors has used 300 lbs. per acre, plowed in for potatoes; the yield, good, so far, having just commenced digging. JOHN HAROLD." We might give much more evidence of the same kind, to prove that every barren acre upon Long Island, might be made productive by a judicious and profitable application of guano; but if there are any persons, who, after reading these pages, are still doubting, we must say they are most incorrigably determined not to profit by the experience of others. To such it would be useless to say more. _Successful Experiment with Guano as a Top Dressing on Wheat, in North Carolina._--On page 17, we gave some account of the application of guano by Henry K. Burgwyn, Esq., since which, we have been favored with the following letter from his brother, T. Pollock Burgwyn, written, as will be seen, not for publication, but simply to give the party from whom he purchased the guano, a detail of his success. "_New York, Sept._ 20, 1852.
