These associations will not admit into membership any one who has not been properly instructed, and who is not reliable. Any physician of standing, and with a sufficient knowledge of the human body, can obtain membership in these associations, and those who are not members may be looked upon with suspicion, although it is quite likely that some of them are reliable; but as they are outside of the associations, they cannot have the facilities of consultation and experience, which are given to those in regular standing in an association.

It is obvious that one of even ordinary ability, who is educated in the profession, is more reliable than one who doctors by his wits, even though he may appear to be successful. Although there are some charlatans in the profession, who practice in their own interest more than in that of their patients, the average physician represents the highest order of civilization. He knows at the start that his profession is not likely to bring him heavy financial return. He goes into it with his eyes open. He is under the strictest rules and regulations, and cannot maintain his standing in the associations, or with the public, if he does not practice legitimately. He has every facility at his command, and although he is not always successful, he is far better able to produce results than is one who has not been properly educated, and who lacks experience and association with other doctors, and who has not had hospital practice. Every reputable physician has not only graduated from a medical school, but was given opportunity to practice in hospitals and elsewhere before he became a family physician. The so-called specialist began as a family physician, and gives his time somewhat exclusively to one disease or to surgery. The surgeon, while a regular physician, specializes in surgery, and comparatively few family practitioners will handle a serious surgical case, except in emergencies. They refer the patient to the skilled surgeon.

The physician is both a curer and preventor of disease. I would advise every one, no matter how healthy he may be, to consult a reputable physician once a year, and to be overhauled, so to speak. Most troubles can be obviated if taken in time. A symptom seemingly serious to the one having it may be of little consequence, and yet it may be the forerunner of an incurable disease. If a good physician is consulted in time, he may either obviate the trouble or prevent its rapid increase. No one should attempt to diagnose his own condition. Even the physician will not do so for himself, because no one can tell by his feelings exactly what is the matter with him or what would better be done. The physician when sick, consults other physicians, if his trouble is of any seriousness. The expense of an annual examination need not exceed two or three dollars, and some physicians will make it for a dollar. They are likely to locate any trouble, although it may have just appeared and the symptom be slight. They will prescribe a treatment, which cannot fail to be of benefit to those who consult them. Therefore, I say, visit a good physician at least once a year, irrespective of your health.

In every city, and in many of the towns, are practicing alleged physicians or doctors, who claim to be unusually expert and able to cure where others fail, or even to cure what cannot be cured. Some of them are graduates of medical schools, and are really good physicians, but most of them are irresponsible and without real ability. Their method frequently makes the patient feel that he is being cured, and cured rapidly. They use appliances and drugs which have an immediate effect, usually to the patients' injury; or they practice the same as regular physicians do and give the patient false encouragement. It seems to me obvious that no so-called outside practitioner, who is not a member of the associations, can possibly possess any information or know of any method of treatment with which the regular physicians are unfamiliar. These charlatans play upon the feelings of the patient, and it is said that some of them keep him sick for financial reasons. Therefore, I warn the reader against any physician who is not a member of one of the two great associations, and who is not recognized by the profession at large. Even though some of them are skillful, it is safer to employ a physician of standing than to take one who makes a business of practicing, and who is not answerable to the rules and regulations enforced by the associations, and who cannot, because of his removal from them, obtain and enjoy the privilege of consultation with other members of his craft. Do not take chances with your body. Better risk the few mistakes made by physicians than by your own doctor.

Perpetual Motion.—Scientists, particularly early ones, made frantic and continuous endeavors to invent what was supposed to be perpetual motion; that is, a machine which will keep perpetually in motion without being replenished or supplied with outside energy. About 60 years ago scientific bodies refused to consider it, as it was proved to be impossible. The "Scientific American," many years ago, likened perpetual motion to an energy which will permit a man to lift himself by his boot-straps.

Petroleum Industry.—The annual production is considerably more than 9,000,000,000 gallons a year.

Philippine Islands.—The Philippine Islands consist of over 3,000 islands, having an area of about 115,000 square miles. The population exceeds 7,500,000; and the density of population is about 67 to the square mile, as against 26 to the square mile in the United States. The climate is tropical.

Pianoforte.—The piano or pianoforte is said to have been invented in Italy and to have appeared in 1714. Germany, however, claims the honor of its invention. It was introduced into England in 1766.

Plate Glass.—The sand, out of which glass is made, is melted until it is of about the consistency of molasses. It is then poured into a casting trough or a table mounted on wheels so it can be run close to the mouth of the furnace. The molten glass is poured into the trough through a sluice-way, and before it hardens, heavy rollers pass over it, reducing it to the required thickness. It is rolled to about 9-16 of an inch, and then by further rolling and polishing it is reduced to the required thickness. It further passes through a smelting oven which thoroughly hardens it. Then, it is again polished.

Playing Cards.—The origin is unknown, although they appeared in Europe in 1350. It is claimed that the Arabs used playing cards at a much earlier date. It is estimated that over sixteen million packs of playing cards are made annually in the United States.
