To this account of the successful practices of these two celebrated English farmers, it may be useful to subjoin a few observations. I have thought it proper so far to present them in detail, in order to develope principles; not expecting a _precise_ adoption of their practices; which indeed, without their or similar superior ploughs and other implements, would be impracticable: but with such instruments as we possess, or may easily obtain, we can materially increase the depth of our ploughing, and I hope contrive effectually to cover our manure. _This should be wholly applied to Tillage Crops_; for which the manuring should be so ample as to ensure a succession of good crops through the whole rotation, without the aid of any additional manure, especially for wheat, rye, barley or oats: for besides increasing the seeds of weeds (with which all our lands are too much infested) such additional manuring, _immediately_ applied to the small grain crops, renders them more liable to injury from mildews. Of this I am fully satisfied, as well from numerous statements of facts which I have seen in books of husbandry, as from the circumstances under which remarkable mildews have otherwise been noticed. One of our countrymen, who wrote a short essay on the subject prior to the American Revolution, has given the only solution of the causes of mildews that has ever appeared satisfactory to me: perhaps at some future time I may find leisure to show the correspondence of facts with his principles.[15] [15] This essay, subscribed "A New-England-Man," is published in the 2d volume of the Memoirs of the Philadelphia Society of Agriculture. (To be continued.) _To Farmers._--In the winter of 1818-19, a gentleman in this city made the following experiment. He placed a turkey in an enclosure about four or five feet long, two feet wide, and three or four feet high. He excluded as much light as he could without preventing a circulation of air, and fed the turkey with soft brick broken into pieces, with charcoal also broken, and with six grains of corn per day. Fresh water was daily supplied. The box or coop in which the turkey was placed, he always locked up with his own hands, and is perfectly confident that nobody interfered with the experiment. At the end of one month he invited a number of his neighbours among others two physicians. The turkey, now very large and heavy, was killed and opened by the physicians, and was found to be filled up full with fat. The gizzard and entrails were dissected, and nothing was found but a residuum of charcoal and brick. To conclude the examination satisfactorily, the turkey was eaten, and found to be very good. Last winter he again repeated the experiment with the same success.
