an linseed-cake. If it be free from mustard, well
steamed, and flavored with a little treacle, or a small quantity of
locust-beans, it will be readily consumed, and even relished, by dairy
and fattening stock.

_Hay._--There is no food substance more variable or more complex than
hay, for under that term are included, not only mixtures of grasses,
but also of leguminous plants--clover, for example. The herbage of no
two meadows is exactly alike; and the composition of the meadow plants
is so greatly modified by differences of climate, soil, and mode of
culture, that we have nothing to excite our wonder in the extreme
variability of hay.

The composition of the hay made from clover, lucerne, and various other
kinds of artificial grasses, is shown in the table--which is based on
the results of Way's analyses:--
