From these statements, proceeding upon the most correct data, it is seen that the value of the produce of one acre of ground, cultivated according to the Flemish system for _three_ years, is, (within a fraction,) 50 per cent. more than what is produced in _four_ years from an equal space of ground, managed agreeably to the most approved principles of English husbandry. The advantages of the Flemish farmer, will appear still more striking, when the nett profit which he clears, after paying the necessary expenses of cultivation is contrasted with that of the English farmer. According to Arthur Young, the English farmer receives about four and a half twentieths of the produce, calculating the gross produce of the soil at twenty. This upon _l._4 18 6-1/4, (the result per acre, for one year, as in Table I.) would give _l._1 2 1-1/4. The produce, per acre, for one year, in Flanders (see Table II.) is _l._7 9 1; the expense of cultivation, land tax, and rent, according to Vanderstraten, is _l._4 0 1; leaving to the farmer _l._3 9 0; or nearly _four_ times the amount obtained by the English farmer. The subject of _Flemish Husbandry_ is by no means exhausted. I shall resume it in future communications. Your's, respectfully, GEO. HOUSTON. _New York, June 1, 1820._ CHESTER AGRICULTURAL SOCIETY. WESTCHESTER, (PENN.) JUNE 21, 1820. [The following interesting document giving an account of the proceedings of the Chester County Agricultural Society, is well worthy the attention of our agricultural readers.--ED.] At a meeting of the Agricultural Society of Chester County, held at the Courthouse in Westchester, 6th Mo. 10th, 1820, Dr. William Darlington, Vice-President, in the Chair; Isaac Sharpless, Secretary. The Committee of Correspondence produced to the meeting the following Report; which being read was unanimously adopted, viz. REPORT. The Committee appointed by the Society to propose plans for its adoption, believing that the objects which may properly claim the attention of the Association, are very numerous, are therefore free to suggest, whether it would not be advantageous to institute several standing committees, each of which should cultivate a particular department of Agriculture, or some of the sciences that may minister to its improvement. If the Society should approve of this plan, we propose that these committees should be made up by voluntary associations among the members as far as practicable, each being at liberty to join himself to such as he may choose, and all vacancies and deficiences in the numbers of said committees should be filled by the presiding officer. They should in no case consist of less than five members, whose names should be entered on the minutes of the Society; and they should each have a secretary to receive communications, to arrange and digest the scattered materials they may collect, and to lay before the society such as may be thought worthy of its attention.
