have been tucked over as in a brown-paper parcel.  Tie it well with whipcord and fasten it to the top bar of your bicycle frame, leaving freedom of course 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 of the disaster is not suspected.  A physiologist is not consulted till too late, perhaps till the disorder in the machinery of life is beyond
