Nitrogen in Soils.

-& I3. L,~wes, in a long eonlmunie,~l.tion upon agriculture, advocates the opinion that tile soilree of all tile nitrogen which is contained ill erol)s is {}mild lit tile soil itself and ill the manures which are SUl/plied. Although the experiments at ]~othamsted may not yet haw. establishe.d this theory beyond controversy, they have given strong indications of its truth, and he thinks that future operations will demonstrate it conclusively, lie regards it as fortunate fi)r agriculture and mleouraglng to those who are engaged in it~ that tile sto(.k' of nitrogen, even in a subsoil which is comparatively poor, is so large as to show very little dimim~tlon after cultivation for a long series of years. --Bdl, de ga See. d'E, eouv., November~ 1882.
