the quantities given, and also of an ordinary serving. "This unique feature makes diet control easy."

For the benefit of those not familiar with the term calories its meaning is explained as a unit, expressing the amount of heat produced in the combustion of food. The greater the amount of fat in the food, the greater the heat production. If the body is not supplied with the required amount of energy daily, it will burn its own tissues to supply its needs. For this reason fatty foods are most useful where much energy is required, or where it is especially desirable to preserve body tissue in wasting diseases.

Foods containing carbohydrates (starch and sugar) perform the same function, as those containing fats, but to a less degree. But while their energy value is less, they are more often accompanied by other useful food consitutents. For instance, cereals, vegetables, and fruits, if not too highly refined, are all valuable sources of mineral salts and vitamines and cereals and many of the vegetables contain important quantities of the proteins.

The number of calories needed per day varies with weight, age, health, climate, and activity. A man of average weight-150 pounds-doing sedentary work will require from 2500 to 3000 calories per day, while a man doing active muscular work may require 3500 to 4000 or more.

A woman's requirement varies from that of a man only as her weight and occupation vary. It is estimated that her weight and food requirement average .8 that of a man, but this figure should not be taken too literally, as her weight and activity often exceed that of the man, in which case she would require more food.

Children require more food in proportion to their weight than adults, because it must provide for growth and constant activity, in addition to the ordinary wear and tear. Since very few children can be pigeonholed as to weight and age, it may be safer to say that a child should eat enough to maintain a constant increase in body weight. There is little danger of overeating provided the eating be done at the proper time and of the proper food.

In "The New Cookery," Chapter I gives a concise treatment of the number of calories needed, with a table estimating the number of calories in an ordinary serving of each common food. Knowing the number of calories needed and the amount supplied by each food, the problem of obtaining an approximately correct amount is easy. A few illustrations from the table are as follows:

The author suggests that the woman who is interested in supplying sufficient nourishment to her family, yet has little time for computation, will find that these figures are sufficiently accurate for her purpose. The book is not intended as a book on dietetics, but is rather a guide for those who wish an intelligent basis and a general knowledge for use in feeding their own families. The discussion is in non-technical terms with such terms described as are most frequently used in discussing subjects of this character.

The amount of space usually devoted, in the average cook-book, to the preparation of meat which has a high percentage of protein, and which is usually considered essential, is given over to meat substitutes in "The New Cookery." Dr. Kellogg, of Battle Creek, says that there is no evidence that high protein intake is better, even in tuberculosis, than an average intake, and since meat protein is more apt to putrify and cause poisons which increase those already present in tuberculosis, the vegetable proteins are much less objectionable in this disease. The vegetables also have the added advantage of supplying more mineral constituents and energy. What is true for the tuberculous patient may be equally true for those who would maintain perfect health.

Those who have been accustomed to depend upon meat as the main dish for the hearty meal of the day, will find in Miss Cooper's book many excellent suggestions for the use of meat substitutes, such as cereals and other grain products, legumes, cheese, nuts, milk, and eggs. A careful perusal of the various recipes shows that milk is used in liberal quantities. Milk can hardly be too highly recommended, both because of its ease of digestibility and because of its usefulness to the body in supplying its needs. It is also one of the cheapest of foods, supplying about three times as many calories for the money spent as round steak.

The growing recognition of the importance of the mineral salts makes this book especially helpful because the foods recommended as meat substitutes are also especially valuable for their mineral content. These are used in a large variety of wholesome recipes with due regard for economy in both time and digestion, and prepared in such a way as to conserve all food material, an example of which is the utilization of the water in which vegetables are cooked for soups and gravies.

The importance of vitamines, about which little is known except the fact that they occur in raw foods, and are, to some extent, destroyed by heat in cooking, but are essential to the organism, has been considered in "The New Cookery," in the many ways for serving raw foods in their natural state. Miss Cooper recommends some raw food as a part of every-day diet-every meal, if possible. "We are continually learning, through scientific research, the necessity of including in the bill-of-fare a more liberal share of natural foodstuffs, which have not been subjected to chemical changes produced by heat." The last chapter of this unique book contains suggestions for planning a balanced meal. In

these suggestions we find a large number of recipes in which milk, many grain products, numerous vegetables, and dried fruits enter as chief ingredients. These foods all contain what the body needs, and, incidentally, at least expenditure.

Without discussing the advisability of com

plete exclusion of meat as contemplated by "The New Cookery," we believe that its influence will be in the right direction, since the substitution of milk, vegetables, and nuts for a large part of the meat in the average American dietary will undoubtedly tend to make it better balanced.

My sakes! what a lot of mistakes
A person makes

About "rest" at the San!
It's "Hurry up-Emmie,
Are you on the cure?

Miss O'Malley 'll be round
And catch you, for sure."
In the Medical Ward
You're kept on the move.
It's Vinson wants this,

And Houle desires that,

Till your temp. goes way up,

And your pulse pit-a-pit.

It's 1, 2, 3 once and 1, 2, 3 twice

And 99-cough, please,
That's ever so nice.

Then just as you've finished,

A physical test! And horoscope?
No, fluoroscope-with all the rest.

The X-ray is killing,
Where Sampson is King.
He says reassuringly

"Really, don't see a thing!"
Now, then once again:-

While you're breaking your neck,
In your hurry and flurry
(With duties a peck)
To climb into bed
Without even prayers said,
A nurse comes around.
Yes, a nurse comes around,
Without even once knocking;
And the questions she asks
Are really quite shocking,
'Are you all out-of-doors?
Are you keeping the rules?

Do you know it is quiet hour?"
Thinking we're fools!

It's time to get up,

It's time to get down.
It's time to get dressed-

There's the 'bus for down town. "Hurry up or you'll miss it, The Movies won't wait;

You 'patients' must beat it;

Now, get on a gait."

Then once again-there are meals to be eaten And milk to be drunk

Or your stomach you're cheatin'.

There goes the bell, the mail's just in

"You get it to-day, for I'm all in;

Will you get me some gauze?-I haven't a

bit.

Suppose, just for instance, I wanted to-—.”
Then it's sweep your own porch,

And make your own bed
(Covers tucked at the feet
Won't reach to the head),
Then empty your "pig"
With what it's been fed.
Your water bottle busted?
In the bed, you said?
Change all your clothes

Or, you'll be dead;

And up you get in the dead of the night

To rectify your horrible plight.

"Lights out, Shiff!" did old Pop say?

No bath for me till another day.

Gee whiz! what a hustle!

By jove! such a bustle!
I'm quite out of breath,

I fear I'm near death.

Dr. Heise wants me?

Heavens! What to me has been laid?

A man in my cottage?

You've got the wrong maid.

It all seems a farce

And really, I'd hike it,

But there's no place like Trudeau,

Begorra! I like it!

EMMA STROMENGER,

Adirondack Cottage San., Trudeau, N. Y.

Few phases of the anti-tuberculosis campaign have had such a sensational development as the open-air-school movement. Beginning in 1907 with one school, the number of similar institutions at the present time in the United States has reached over a thousand and is increasing by the score each week of the school year. With the emphasis that has been laid upon child welfare generally throughout the United States and with the stress that anti-tuberculosis workers have been placing upon the prevalence of childhood infection, it is but natural that the open-air school and the fresh-air class should be coming into its own at this time. That cold weather need be no bar to outdoor classes is evidenced by the success of such schools in North Dakota and other rigorous climates as indicated in these pages. That expense need not prohibit any community from establishing an open-air school is evident from a perusal

of Mr. Kingsley's article.

The open-air school and the fresh-air class have done more, however, than to provide accommodations for a few thousand children. Probably its greatest mission and claim to merit lies in the fact that it is educating the schoolmen of the country to the necessity for fresh air for all school - children, both sick and well. In New York City alone the comparatively small number of freshair classes for anemic children has produced a far greater number of openwindow rooms for normal children. Both teachers and children are coming to realize that they study better, sleep better, eat better, and, in general, feel better if they keep the windows open during the school hours.

When the American public school shall have been emancipated from the thraldom of so-called ventilating engineers and janitors, just as it is being emancipated

1. Besides the lungs, how do the bones and other parts of the body become infected with the tubercle bacilli?

2. Can a T. B. person without harm exercise a little daily when running a normal temperature, except a 99% occasionally?

3. After having had bronchitis for a month or more can a tuberculosis patient recover from it without any harmful results?

4. How long does it take?

5. If there is a way, would you please print an article on how to prevent a patient from catching cold? I note that you refer to an article in the March, 1914, number of the JOURNAL OF THE OUTDOOR LIFE, but I was not a reader at that time and haven't such a copy. A READER.

1. Tubercle bacilli lodge in the tissues from the blood.

2. The question of exercise of any individual patient must be determined by his physician.

3 and 4. These are too general questions for us to answer. There are too many factors involved.

5. A copy of the number to which you refer will be sent you on receipt of 10 cents.

TO THE EDITOR:

Will you tell me in what number of the JourNAL I will find a clear article on the helpfulness of pneumothorax?

When a patient once starts the treatment can he ever stop it?

Why is it only given to advanced cases?

Is it only given to stop a hemorrhage or to prevent the disease spreading into the other lung?

Does any patient who has taken it for a number of years ever have the use of that lung?

You will find that all of the matters upon which you request information are treated in an article on Artificial Pneumothorax in the January, 1914, number of the JOURNAL OF THE ÕUTDOOR LIFE.

TO THE EDITOR:

Is the J. B. Murphy formula for the preparation and administration of tuberculin intended for surgical cases only, or is it also used in the treatment of pulmonary tuberculosis?

2. As a general thing would it be considered wise in the treatment of pulmonary tuberculosis to give two complete courses of this Murphy tuberculin, spreading the treatment over three years, and averaging better than a treatment a week? Kindly consider that the last dose in each of these courses contains two drops of clear tuberculin.

3. Would four years of various kinds of tuberculin ever be advisable?

4. Is it true that the excessive use of tuberculin sometimes defeats its own purpose and destroys the anti-bodies which it is intended to fortify?

5. Has anything ever been published in your magazine regarding the "potassium iodine" (K-I) treatment? Is it still in the experimental stage or may something definite be expected from its use, at least in certain cases? Is it being used a great deal?

6. Has Spengler's "I-K" treatment ever been used in this country? Are there any English translations of his books on this subject? Is it true that this treatment has been in use in the sanitariums of Europe for several years?

7. I would like to suggest that you sometime publish the names of the men who are devoting their lives to scientific research in an effort to find cures for tuberculosis and other diseases, and from time to time tell us something about them, so we may learn to honor them and place them in our estimation above all other men.

NEW MEX. SUBSCRIBER.

1-2-3-4. We cannot go into the details of tuberculin treatment. The answers to questions you ask, if obtained from several physicians of equal experience, would probably vary considerably. In other words, the administration of tuberculin is not a hard and fast method of treatment. We would refer you to articles on this subject which we have published in the April, 1913, and September, 1914, numbers of the JOURNAL OF THE OUTDOOR LIFE. Also you will find the whole subject of tuberculin treatment adequately treated in Hamman and Wol
