for the handles and the front wheel to move and
steer. Push the tent-poles through the lashings and start for your
camp at a comfortable four or five miles an hour. You will find it
easy to move camp at the rate of twenty miles a day and will see a
great deal of country in the course of a fortnight.

The sausage on the bicycle shown in the illustration may be taken to
contain all the gear and a little food. The rucksacks will take the
rest and each man's most precious personal belongings. There is a
small parcel tied to the handle-bar, scarcely to be seen because it is
smaller than the end of the sausage. It is a complete tent tied up in
its ground-sheet.

HOW MUCH SHOULD WE EAT: A WARNING.

_This article, by one of the pioneers of modern dietetics, is in the
nature of a challenge, and is certain to arouse discussion among all
who have studied the food question closely._--[EDS.]

When men lived on their natural food, quantities settled themselves.
When a healthy natural appetite had been sated the correct quantity of
natural food had been taken.

To-day all this is upside down, there is no natural food and only too
often no natural healthy appetite either. Thus the question of
quantity is often asked and many go wrong over it. The all-sufficient
answer to this question is: "Go back to the foods natural to the human
animal and this, as well as a countless number of other problems, will
settle themselves."

But supposing that this cannot be done, suppose, as is often the case,
that the animal fed for years on unnatural food has become so
pathological that it can no longer take or digest its natural food?

Those who take foods which are stimulants are very likely to overeat,
and when they leave off their stimulants they are equally likely to
underfeed themselves. Flesh foods are such stimulants, for it is
possible to intoxicate those quite unaccustomed to them with a large
ration of meat just as well as with a large ration of alcohol. The one
leads to the other, meat leads to alcohol, alcohol to meat. Taking any
stimulant eventually leads to a call for other stimulants.

How are we to tell when a given person is getting enough food, either
natural or partly natural? Medically speaking, there is no difficulty;
there are plenty of guides to the required knowledge, some of them of
great delicacy and extreme accuracy. The trouble generally is that
these guides are not made use of, as the cause
