A number of years ago, I saw a large pile of compost in the farm-yard of Mr. Pond, of Milford, Conn., and witnessed its effect as applied by that gentleman to a field of sixteen acres of fine gravelly or coarse sandy soil. The soil, from having a light color and excessive porosity, had become dark, unctuous, and retentive of moisture, so that during the drouth of 1856, the crops on this field were good and continued to flourish, while on the contiguous land they were dried up and nearly ruined. This compost was made from a light muck, that contained but three _per cent._ of ash (more than half of which was sand), and but 1.2 _per cent._ of nitrogen, in the air-dry state--(twenty _per cent._ of water). Three loads of this muck were used to one of stable manure. Here follow some estimates of the value of this compost by practical men. They are given to show that older statements, to the same effect, cannot be regarded as exaggerated. Mr. J. H. Stanwood, of Colebrook, Conn., says:--"Experiments made by myself, have confirmed me in the opinion that a compost of equal parts of muck and stable manure is equal to the same quantity of stable manure." Mr. Daniel Buck, Jr., of Poquonock, Conn., remarks:--"8 loads of muck and 4 of manure in compost, when properly forked over, are equal to 12 loads of barn-yard manure on sandy soil." Rev. Wm. Clift, of Stonington, Conn., writes:--"I consider a compost made of one load of stable manure and three of muck, equal in value to four loads of yard manure." Mr. N. Hart, Jr., of West Cornwall, Conn., observes of a peat sent by him for analysis:--"We formerly composted it in the yard with stable manure, but have remodeled our stables, and now use it as an absorbent and to increase the bulk of manure to double its original quantity. We consider the mixture more valuable than the same quantity of stable manure." Again, "so successful has been the use of it, that we could hardly carry on our farming operations without it." Mr. Adams White, of Brooklyn, Conn., states:--"The compost of equal bulks of muck and stable manure, has been used for corn (with plaster in the hill,) on dry sandy soil to great advantage. I consider the compost worth more per cord than the barn-yard manure." _Night Soil_ is a substance which possesses, when fresh, the most valuable fertilizing qualities, in a very concentrated form. It is also one which is liable to rapid and almost complete deterioration, as I have demonstrated by analyses. The only methods of getting the full effect of this material are, either to use it fresh, as is done by the Chinese and Japanese on a most extensive and offensive scale; or to compost it before it can decompose. The former method, will, it is to be hoped, never find acceptance among us. The latter plan has nearly all the advantages of the former, without its unpleasant features.
