It is remarked in the JVew England Manual of Agriculture, that " unleached wood ashes are of great value in the cultivatioa of many crops, especially Indian corn, turnips, beets and potatoes, because of this great amount of carbonate aud other salts of potash which they contain; and so important is potash to these plants, that they are often called potasn plants. L:achf:d oshes are of less general value, but still are a very valuable fertilizer, by reason of the salts which they contain, and which, though not soluble in simple water, may be rendered soluble by the influence of other salts, of air and of the vital power of plants, and may be thus taken up into the circulation, and again perform the service they had performed in the plants from the combustion of which they come, fhey have important effects when mixed in compost ; 4.
