prevented at all events. In about twenty-four hours, the pro- cess will be complete, and you will have a quantity of ashes ready to lay on your land at any time you wieh. Any, and all orts of vegetables, and weeds of everv description, if used green, will answer the purpose. They will doubly Serve the farmer, as they will not only be got at a small expence, but will, in time, render his farm more valuable, by its being de- prived of all noisome weeds.

<< But if this compozition answer the purpose, as I flatter myself it will, a very Short time will See almost every weed destroyed. Supposing that to be the case, 1 have mage a calculation with clover grown for the purpose; for instance, 1 will take one acre of clover, which at one cutting, will pro- duce from fourteen to eighteen tons of green vegetable mat- ter, and will require about three tons of lime; this, when de- composed by the above process, will yield ashes suflicient to manure four acres, the value of which I estimate at Something under 41. The clover, according to the value of lands here, at 21. which, taking the average of the kingdom, is too much: the lime also at 21.; but that will vary according to the dis» tance from which it is to be fetched; take them together, I think the above will be about the average value. Now if this 1s the case, and as far as I have been able to try it,[ find it 80, how valuable must this method be to the community in general. If it answers the purpose, I Shall feel myself much obliged by the Society's making it as public as they possibly Can,

<< The vegetables Should be used as Soon after they are cut as possible, and the lime as fresh from the kiln as the distance will allow of, as on those two circumstances depends the good pess of the composition."

To the Editor of the Agricultural Magazine. SiR,

HAVE occasionally seen in your miscellany meteorologi-

dal observations transmitted by your correspondents in various parts of the kingdom. It is acknowledged on all hands, that this Subject bas the nearest connection with the produce ot the field. It is in vain that the Soil is of therichest kind, in vain that the culture is most skilfully conducted, in vain all 1ihe labour and ingenuity of man is wisely directed, it the Season be not propitious. But although it is universally admitted, that the atmospherie phenomena are in this respect
