I think that lime is best when mixed with other materials, The farmers in the sandy districts of New Jersey who use marl largely, think it best when mixed with lime or barn-yard manure. Plaster of Paris is best for sandy soils, and benefits all kinds of crops grown upon them; it Is the best thing for clover I ever used. Road-earth is best when composted with other materials, after lying in a heap and being frequently turned in a year. The same is true of coal ashes; street-sweepings are also best after lying in a heap twelve months and turned over twice. 1 have heard it often asserted that the ashes of the peat used In Ireland as fuel and called turf, contains more fertilising matter than any other thing six times Its bulk. A relative'fifteen miles from Londonderry informs me that the ashes of the " peat" was the best thing he ever used for his vineries, peach and nectarine houses, and also for his wall trees. He exchanged stable manure for it among the people. Now, we all know how valuable peat is in pot culture, and the older the better; so we may well presume that there must be a virtue in the ashes also.

An English friend of mine from Wiltshire used to tell me that straw was used for fire to cook with, and the fanners there manured their lands with burned turf, (sod •,) they had turf plows that turned up the turf and made it into rolls three yards long; it was put into large heaps and set fire to, and after burning some weeks into a mould, it was spread upon the land, and produced a good crop. The moorland farmers in Scotland do the same thing, and they think that double the quantity of grass grows where the ashes of the heather falls, when they burn it upon their pastures in spring.

I once top dressed a lawn with grains from John Taylor's brewery at Albany, N. Y., and it produced a wonderful effect upon the grass. At the same place I manured an acre with hops from the brewery, that had lain in a large heap and was well fermented; I then sowed parsnips upon it; the leaves all over grew five feet high. The late Jesse Buel and James Wilson, as well as other cultivators of note, came to view them, and said they never saw anything like them. A patch adjoining was manured with yeast from the brewery, and yielded a very heavy crop of carrots.
