Braconnot and Einhof, in Professor Johnson's Lectures on Agricultural Chem

These analyses differ materially from those of the same seeds grown in this country. Whether the difference is owing to the influences of soil or climate, I am, of course, unable to say. Probably both have their effect. The seeds in the following analyses were very dry and well ripened:

For our present purpose we will use the last analyses, both because they were made of seeds grown in this country, and, like the other seeds, before considered, they were perfectly ripened and naturally dried. The casein in the last a alysis corresponds in nature to the legumen in the others.

The only remaining food used for fattening animals is the cake composed of the hemp and linseeds, called oil-cake. With the great fattening properties of

this cake all are acquainted. The composition of this cake, as given by Professor Johnson, is as follows:

These analyses, the only ones available to me at present, show not only valuable fattening properties, but also rich nutritive elements, and establish this as one of the most valuable of the concentrated foods.

We are now acquainted with the composition of the different kinds of food used for animals, aud it only remains for us to arrange them into a condensed form and prepare tables of their comparative equivalents, to be able to ascertain the value of each, and also the kinds which may be used together the most advantageously. It is of course impossible to make any calculations regarding the cost of the various kinds, as they vary in different localities. The analyses of grass and hay, as they appear in the following table, are the results of averaging the analyses of all the species hitherto considered; they will probably represent the constituents of the superior quality of English hay as grown in this country.

Table of comparatire equivalents, prepared from the preceding analyses.

A careful examination of this table, prepared from the best English, American, and German authorities, and a comparison of the money value of these articles of food, modified as experience may suggest, with their feeding value as here given, would be of immense benefit to the farmers, and save them thousands of dollars, often injudiciously expended.
