iderable quantity of heat-producing food, that is,
food containing a good supply of hydrocarbons (fats), and carbohydrates
(starches and sugars). Many vegetable foods are rich in these
properties, as will be explained in the essay following dealing with
dietetics. Strong and enduring vegetable-feeding animals, such as the
musk-ox and the reindeer, flourish on the scantiest food in an arctic
climate, and there is no evidence to show that man could not equally
well subsist on vegetable food under similar conditions.

In an article entitled _Vegetarianism in Cold Climates_, by Captain
Walter Carey, R.N., the author describes his observations during a
winter spent in Manchuria. The weather, we are told, was exceedingly
cold, the thermometer falling as low as minus 22 deg. F. After speaking of
the various arduous labours the natives are engaged in, Captain Carey
describes the physique and diet of natives in the vicinity of
Niu-Chwang as follows: 'The men accompanying the carts were all very big
and of great strength, and it was obvious that none but exceptionally
strong and hardy men could withstand the hardships of their long march,
the intense cold, frequent blizzards, and the work of forcing their
queer team along in spite of everything. One could not help wondering
what these men lived on, and I found that the chief article was beans,
which, made into a coarse cake, supplied food for both men and animals.
I was told by English merchants who travelled in the interior, that
everywhere they found the same powerful race of men, living on beans and
rice--in fact, vegetarians. Apparently they obtain the needful proteid
and fat from the beans; while the coarse once-milled rice furnishes them
with starch, gluten, and mineral salts, etc. Spartan fare, indeed, but
proving how easy it is to sustain life without consuming flesh-food.'

So far, then, as the physical condition of those nations who are
practically vegetarian is concerned, we have to conclude that practice
tallies with theory. Science teaches that man should live on a non-flesh
diet, and when we come to consider the physique of those nations and men
who do so, we have to acknowledge that their bodily powers and their
health equal, if not excel, those of nations and men who, in part,
subsist upon flesh. But it is interesting to go yet further. It has
already been stated that mind and body are inseparable; that one reacts
upon the other: therefore it is not irrelevant, in
