Let me say, in concluding this short article on my chromolume, to those who will follow up this method of photo-therapeutics as an adjunct to the treatment that they will be most amply paid for the trial. With light rays, hygienic food, fresh air, exercise and such suitable remedies as are indicated according to the case in hand, 75 per cent of the tuberculous patients are curable; that is, curable to a certain extent, according to the lesions or pathological changes already present at the time the case comes under treatment.

Of course we all understand that pathological conditions which have in certain stages of this disease left their markings, cannot be changed. We cannot give the patient any more breathing capacity after

One important factor must always be remembered in this method, that much time should be alloted to each case-no less than an hourly sitting daily. This phototherapy is most admirably adaptable for sanitarium and hospital purposes. For years I have adopted a system of generating these colored rays of light. Where practical I have advocated the construction of solaria; these of course are more suitable to country than city use; also in a climate where the sunshine is in abund

ance.

The solaria must be constructed on plans which provide for all contingencies, and the important necessities, heating, ventilating, cooling, glazing by colored glass intermixed with white glass, proper exposure, etc., are some of the principles

previous meeting of this society. This is as it should be. Our profession, crowned with the vast and marvelous achievements of the century that has just passed into history, demands of the physician of to-day that he be a man worthy of the past, prophetic of the future-a man with a grand combination of heart, conscience and brain.

To build up such a profession in Colorado must be our earnest and constant endeavor. To do so we must begin at the fountain head-the education of the individual. One of our most honored members read a paper, "Legislation versus Education," at our last year's session, in which he very justly took our profession to task for neglecting the education of the masses in matters of health and hygiene. Let us see to it that we have a fully equipped and thoroughly educated profession, and at the same time devote our best talents to the education of the masses in all matters of sanitation and health-both public and private.

To accomplish this in the most practical way we should begin with our public schools. Preventive medicine and hygiene should have its first application in the school room. Here our future generations of men and women get their first and lasting impressions, and here, then, these lessons should be first taught. In consideration of the enormous annual loss to the government and to society through disease, it is self-evident that it is the duty of the government to protect its people from the peril of preventable disease.

Our local and state boards of health should have enlarged and absolute powers in this direction. They should have the power to enforce medical supervision of all public schools, not only in times of epidemic diseases, but at all times. The old saw about an ounce of prevention, etc., applies here. A national board of school hygiene, with state and local boards, has been suggested, but I fancy

the machinery we already have, in our state and local boards of health, if given the authority and put in motion, would accomplish the desired results.

Health officers should be chosen on merit, rather than because of political affiliation or because they need the work. They should be men who will do their work, regardless of opposition which is so frequently in evidence and which is generally due to ignorance. In many places school physicians have been appointed to have general sanitary supervision of the public schools. The wisdom of having such supervision is obvious. His authority should extend to a right to make examinations at stated times of all school children, segregate those afflicted with infectious diseases, advise as to errors of refraction and as to disposition of weak and poorly developed children who are really injured by confinement to school. He should be preferably a man of some years' experience rather than a novice.

To better our professional condition there is no more potent factor than the county medical society. Every county in the state should have a good, live, working society. Here lies the secret of a vigorous and successful state society. We have, in Colorado, been fortunate in having for members of our state society some who have had experience in Pennsylvania and other eastern states where the plan of organization which we are now following has been thoroughly tried and where it has proven so successful. Let us foster our county organizations above all else.

"The tendency of the age seems wellnigh world-wide for isolated groups of the community-trades, professions, etc., -to adopt for the common good of their membership certain methods of communal activity. The unanimity with which the medical profession seized the opportunity to reorganize on a basis effective for the
