It has been noticed consistently, in all soluble substances, that there has been
a washing down of the same from the top of the pit down to the bottom. This is
best seen in the soluble minerals, especially the alkali salts. Even silica, an in-
soluble substance, exhibits this downward movement.

It has been established that slow filling with watering results in the production
of good silage with the least losses in the various constituents.

Acknowledgment.—I wish to acknowledge most gratefully the valuable advice
and helpful criticism given by Mr. F. J. Warth, the Physiological Chemist, during
the preparation of this paper as well as in the carrying out of the experiment.
My thanks are also due to Mr. P. A. Seshan, B.A., for help rendered on various
occasions during the course of this work.
