vised what is known as a fresh air bed-a bed which makes the luxury of sleeping out of doors available to dwellers in city houses in which sleeping porches cannot be installed. The bed projects from the wall of the house about three feet and is enclosed by a railing, as indicated in the exterior view. A rounded screen protects against insects, and for rainy weather a waterproof curtain, which can be drawn down to any distance from the floor, is provided. In addition to this there is a metal canopy which swings from one side of the bed to the other and affords complete protection in case of storm.

This is the most scientific built-in bed known, for, besides having all the advantages of the folding bed, it provides for

In preparing for the night it is not necessary to shift the other furniture, for the bed, when in use, does not require extra floor space; the parts of the settee simply fold back out of the way and, after the bed is occupied, the metal canopy that admits the outer air is swung up and over the couch. This, although it can be raised to any height, is in mild. weather usually swung all the way so that the bed is shut off from the room itself; however, in case a through draft is desired, it may be swung directly overhead, leaving ventilation spaces on both sides.

For night reading an electric light is installed at the head of the bed. This device has been received very favorably on the Pacific Coast and is equally well suited for eastern summers.

QUERY:

F

ROM the date of its origin in Germany, fifteen years ago, the exact composition of Sanatogen has been published in booklets, advertisements, in letters, and, in fact, whenever and wherever occasion offered. Moreover, this composition is stated plainly on a leaflet that is wrapped around every packet of Sanatogen sold to the public. So you see the assertion that we are hiding the composition of Sanatogen is plainly untrue.

While it is correct to say that a dollar's worth of flour has many times more calories than a dollar's worth of Sanatogen, it is likewise true that a dollar's worth of oleomargarine has many times more calories than a dollar's worth of finest steak, and a pound of laundry soap or lard has just as many calories as fifty eggs.

Caloric value is not food value. It simply expresses the heat or energy producing value of a given substance. It is neither scientific nor correct to attempt to express food value simply in terms of calories. A calorie is only a measure of heat, representing the amount of heat that a food can produce in the body or outside the body, provided it can be digested. A food substance can be high ir. caloric value, yet on account of the difficulty of its digestion be very poor in nutrient value. The most valuable and vitally necessary portion of the food in health or in disease is that which repairs tissue waste or builds new tissue. Without it the body dies. Such portion of the food is called protein. Sugar, starch and fat do not build tissue or repair it. They do furnish fuel to produce energy. Hence protein has true nutrient value, but the other kinds of food only energy value. To assert that the caloric or energy value of a food means the same thing as its nutrient value is deceptive, and is contrary to fact.

Sanatogen is a scientific food for those who are run down or nervous. It is not intended to replace daily food, but to be given with it. Sanatogen is a scientific compound, designed to act as a help to nutrition, endowed for that purpose with special nutritive and tonic properties not found in everyday foods. In point of easy and

perfect digestion Sanatogen is not approached by even the most easily digested ordinary food. As a reconstructor of nervous energy Sanatogen stands in a class by itself.

Are our claims for Sanatogen exaggerated? Any claims made for a substance intended to promote health must be capable of proof in two ways. They must first of all be in harmony with known scientific facts. Second, they must have been verified by actual experience; this is to say, competent observers must have seen actual evidence of the results claimed for such substance. How does Sanatogen stand in this respect?

As you know, Sanatogen is an original chemical compound of about 95% purest albumen of milk (protein) and 5% glycero-phosphate of sodium. The two substances form a chemical unison so original and useful in its design that it has been granted Letters Patent in nearly every civilized country. We claim that this compound is able to produce superior results upon digestion and assimilation, upon nutrition, and that, above all, it is capable of acting as a tonic upon the nervous system. Can this claim bear theoretical investigation? How does Sanatogen actually behave in the human system? Has this question ever been scientifically investigated? Has it ever been shown that the human organism takes up the phosphorus of Sanatogen better than it would take up the inorganic kinds of phosphorus?

Yes, most emphatically, such investigations have been made by physicians of high reputation. One of these, by Professor Tunnicliffe of King's College, London, was read before the International Congress of Medicine in 1906. This authority found that the taking of Sanatogen was followed by most remarkable increase of phosphorus and of protein in the system. Not only was this increase due to the constituents of Sanatogen themselves, but it was clearly shown that Sanatogen so acted on the other foods taken with it that the system appropriated from them much more protein and phosphorus than it did under a diet without Sanatogen.

Now this proves very definitely that Sanatogen acts first of all as a cell food, and second as a

purveyor of phosphorus to the nervous system. Similar investigations were made by several other scientists and with equally definite results.

So here we have a scientific basis-one of several-for our claim that Sanatogen does invigorate the nervous system, since debility of the nervous system is very often, if not always, dependent upon a loss or deficiency of phosphorus, and if the system can be brought to absorb with the aid of Sanatogen more organic phosphorus than it is able, unaided, to extract from the ordinary food, a strengthening and invigorating of the whole nervous apparatus is the natural and logical result. If we can bring the body to absorb more albumen (protein) through the blood into the body cells, we inevitably increase the efficiency, endurance and resistive force of the organism.

Now as to the practical results. The final test of the efficiency of any preparation lies in the crucible of experience. Sometimes a product is right in theory but fails lamentably in practice. What is Sanatogen's record of achievement in actual practice? The medical profession of five continents have tried it, are using it, and surely their experience, their opinion, should count. We have received by actual count over 18,000 original letters from physicians who have themselves watched the beneficial effect of Sanatogen. There have appeared in the leading medical journals of the world over 120 original contributions by members of the medical profession, including authorities of world-wide renown, detailing the good results of Sanatogen in a variety of conditions.

From this authoritative material we have drawn the claims we make on behalf of Sanatogen. When we say that Sanatogen will invigorate and revitalize the nervous system we do not say it simply because we fancy it will, but because from the authoritative reports which we have received we feel there can be no doubt that it will do these things. When we say that SanatoIgen will be of remarkable benefit to frail and anemic people, we say this because we have back of us the incontrovertible evidence of scientific authorities. When we say that Sanatogen will give you better health, better strength, that it will endow you with added power to endure and to resist, we merely reiterate what thousands of doctors have virtually said, either in their letters to us or in original articles which have since become a definite part of medical literature. Only to illustrate: A New York physician, head of a clinic, writes, after detailing his experience, that he considers Sanatogen almost as a specific in anemia, that is to say, he considers Sanatogen almost unfailing in anemia. When a physician of standing makes such an utterance, based upon actual observation, and when his utterance is corroborated by hundreds of other physicians,

are we not justified in saying that Sanatogen will help anemic people? Prof. von Noorden, head of the most famous medical clinic in the world, the first medical clinic of the University of Vienna, writes that he considers Sanatogen an excellent albuminous preparation, and that he finds it especially valuable in anemic conditions. Is such an utterance from one of the greatest living authorities to be ignored?

Prof. C. A. Ewald of Berlin, also an acknowledged authority, states openly that he has watched the effects of Sanatogen in a large number of cases and that he has observed excellent results from its use in neurasthenia. Another physician, director of a large sanitarium in Maryland, writes that from his experience he is able to say that Sanatogen has positive reconstructive force in neurasthenia. In view of such definite statements, which, moreover, are corroborated in thousands of instances by other physicians, can we be accused of exaggeration when we say that Sanatogen will help nervous people, that it will infuse new strength into the nervous system impoverished by overwork, worry or illness?

As a matter of fact, if we were to publish all the results reported to us by physicians, our claims for Sanatogen would be ten times stronger than they actually are. Viewed in the light of what we could claim, our statements are truly conservative, as indeed they should be. We do not claim Sanatogen to be a cure for consumption, Bright's disease, etc. We claim it to be simply and truly a natural, healthful food-tonic, designed to increase the efficiency of the human system, to aid digestion and assimilation, to act as a tonic upon the nervous system; in short, to strengthen the fundamental sources which make for health and strength and long life. That Sanatogen supplies a real need its ever increasing success abundantly testifies. The remarkable benefits it has conferred and is daily conferring upon people in every walk of life form an enduring monument to its intrinsic value.

If you have carefully read these vitally important facts about Sanatogen you will realize that Sanatogen is perfectly able to stand on its own record and needs no defense, but it is necessary to dispel misconceptions, misstatements, spread through ignorance or otherwise. We cordially invite everyone interested to write to us for an interestingly written booklet fully describing the nature of Sanatogen and what it is able to do for those who are run down and nervous. The booklet is written by a physician and well worth reading. It is sent free and postage prepaid to any one who will ask for it. Sanatogen itself can now be obtained at any good drug store.

shell dredges are scattered through the lowlands, new and larger ones are constantly being built. Just now the Netherlands district is completing a dredge with a boom 220 feet long, carrying a 15-ton bucket capable of lifting seven to ten cubic yards at a time, with a capacity of moving and placing 5,000 to 6,000 cubic yards a day.

Along the Mississippi the mule and the negro are to this day the main factors in the construction of the levees. Only within the last few years have steam shovels and excavators been put to work here and there. In the application of the science of mechanics to the problem the Mississippi is a generation behind the times. Wrote P. A. Haviland and F. H. Tibbetts, California Engineers, after a survey of the Mississippi work during the height of the 1912 flood:

"No levees observed in the Mississippi Valley, except those of the city of New Orleans, were so large or so substantially constructed as some which the writers have seen in California. Methods of construction are very inferior and the unit costs of the levees proportionately higher. The great floating clamshell dredges in common use in California would probably create a sensation along the Mississippi River, and could certainly do most of the work much cheaper."

"Cheap" negro labor can never hope to conquer the Mississippi; six skilled men and a dredge will do faster, better, more efficient work at lower cost than a battalion of darkies and mules.

Observe the consequences of applying mechanics instead of muscle to the problem. On the great Mississippi 8 feet is the average width of the levees' crown; on the puny Sacramento the standard was 10 feet; the latest levees, like those of the Netherlands and the Natomas districts, have a crown width of 20 feet; at West Sacramento the river levees are 40 to 80 feet wide at the top. On the Mississippi the engineers provided a margin of safety 3 feet above the highest known water mark; on the Sacramento the engineers are building the levees 6 and 7 feet above extreme flood stage. Only 60 of the 1,600 miles of the lower

ment; on the Sacramento the Lisbon and the West Sacramento districts, besides the revetment of the river levees, have protected their back levees by solid layers of reinforced concrete 4 inches thick.

These statements and comparisons do not imply adverse criticism of the engineers in charge of the Mississippi River work. It was not their fault that 586 miles of levee were and are below the grade that proved too low by five feet. Congress never asked the engineers what a comprehensive scheme of flood control would cost. Munching the contents of the pork barrel, the legislators waved the "aid to navigation" subterfuge and handed out an occasional million, telling the engineers to make the money go as far as possible in levee construction. Under these circumstances systematic work of permanent character was impossible.

Given sufficient funds, modern engineering is equal to the task of controlling the floods in the principal rivers through a combination of storage reservoirs, of levees, and by-passes. The real trouble arises when the question of financing is raised, when red tape, fat pork, the selfish aim of small-bore politicians, the greed of private landowners, local jealousies, lack of co-ordination, the obstinacy of touchy engineers, the doctrine of States' Rights, and the inertia of the flood-proof masses are twisted into a confusing tangle. Division of the cost of comprehensive flood control between the Federal Government, the affected States, and the districts and communities directly benefited, would seem to be the equitable way of solving the financial problem, but the task of conciliating and harmonizing these conflicting interests would postpone the start until the first Prohibition President is inaugurated.

In view of past performances in the fatfrying line, in view of the inexorable fact of future flood catastrophies, perhaps the Newlands Bill with its half-billion appropriation is the most efficient wand with which to control the coming floods. And the expense it throws on the shoulders of the nation is the penalty we must pay for the all-pervading, universal diet of
