Not only do the relative proportions of starch and gluten vary in the
same seed when grown in different countries, but even when grown in
the same country, according to the kind of manure put on the soil, a
point of great importance to agriculturists, when known and attended
to.

miners, in winter, prefer oat-cakes to wheaten bread, finding that
this kind of nourishment enables them to support their strength and
perform their labour better. In summer they say oat-cake heats them,
and they then consume the finest wheaten bread they can
procure."--_Sir H. Dacy's Agricultural Chemistry, 5th edit., p. 143._

The propriety and advantage of this practice is established by the
recent investigations of Boussingault, who found that oats contain
more than double the quantity of nitrogen which exists in any of the
other cereal grains.--_See Annales de Chimie et de Physique, tom.
lxvii. p. 408-21._
