P. S. It would aiso be obliging if A. N. would inform us as to the relative advantages of Sowing turnips with the corn drill,(as mentioned by Agricola Norfolcieysis) and the turnip Sced machines be 50 accurately described in a former Number. Can. be favor ws, with a drawing of that constructed by « Mr. Bailey," which he said was the best? I Should also be glad to See a drawing of a Merino ram?

WA GRP 27 HAIE ON MANURE AND TILLAGE. To.the Editor of the Agricultural Magazire.

WIR, Dec. 15th, 1805. ERCEIVING that tbe doctrines of Tull, Duhamel,&e. have rather misled Tyro Alter; and being determined 19 Combat these doctrines under whatever Shape they appear, I must again take the liberty of addressing to you a few -observations against the dangerous practice to which they may lead inexperienced husbandmen.

That practice Seems to aim at,nothing less than the over- throw of a system upon which the present fertility of our lands in a great measure depends; namely, the application of manures.--These authors(8ays Tyro Alter)“ maintain that It is more profitable tv increase the fertility.of land by f/lage than manure; because only a certain quantity of dung cam be had, the produce of twenty acres being Scarecly Suficient to manure one, whereas the particles of the earth may be pul- Verized and divided at pleasure; because plants reared in dung, do not possess the fine favour of those produed by a natural S01]; and because dung breeds and harbours inaects, which afterwards feed upon and spoil the plants Sc.

In respect to the first objection, I will venture to assert that, under proper management, the dung from the produce of twenty acres will manure much more than vne; nay that under the improved husbandry, muck may be raised in sufh- cient quantities to manure from one half to upwards of two- thirds of ihe fallow-grounds yearly. The quantity will, no doubt, depend, in some megsure, upon the nature of the Soil; but where that is unfavourable, it is the duty of the farmer to Supply the deficieney by composts, lime, marls, „Kc.&c,=-As to the particles of the earth being divided at Ppleasure by?z/age, I am far from harbouring 1the smallest wish to depreciate the benefits we- derive from pulverization and good culture. But pray how can the enemies of manurin; Prove that these are less attainable under muck,- lime,&c.?
