The Rev. H.A. Boardman, D.D., of Philadelphia, writes under date of October, 1868, to a public journal, the following: "* * * The question is often asked, 'how far is St. Paul to be recommended as a resort for invalids?' If one may judge from indications on the spot, invalids themselves have settled this question. I have never visited a town where one encounters so many persons that bear the impress of delicate health, present or past. In the stores and shops, in the street and by the fireside, it is an every-day experience to meet with residents who came to Minnesota, one, two, five, or ten years ago, for their health, and having regained, decided to remain. I have talked with some who, having recovered, went away twice over, and then made up their minds that to live at all they must live here. * * * * *"

The statements of these observing and reflecting men are of the first importance, and require no scientific deductions to prove the benefit certain classes of consumptives may receive by a residence in Minnesota; but if it is found that whatever of data in meteorology there is bearing on the climate of this State, confirms the universal public judgment, this then becomes a matter of most agreeable interest.

It seems that the dryness and equability are the important features, as before observed. A gentleman, given somewhat to investigation, made the statement to us, while in St. Paul, that he had carefully watched the ice-pitcher on his table during the summers, and that it was rare that any moisture accumulated upon the outside of the same, as is commonly the case elsewhere. This is itself a most interesting scientific fact, and completely demonstrates the great dryness of the atmosphere during even the wet season of the year, as we have found the rain-fall in summer to be about two-thirds of the whole annual precipitation. Physicians have not generally thought that the summer atmosphere of this State was any improvement upon that of other localities of like altitude, judging from the rain-fall, which, being up to the average of this latitude elsewhere, left as much of moisture, they have concluded, floating near the surface as at other points, and they are led to send patients into less dry districts, or even, as is sometimes the case, to the sea-shore. Graver mistakes could not well occur than these, and it is to be ascribed to the little definite knowledge we as a people have on medico-meteorology. Except for debilitated constitutions, which, it is true, precede many cases of consumption, the sea-shore is to be avoided, especially in every instance of diseased lungs. Doubtless, the habit of advising a trip to the sea-side for the relief and cure of whooping-cough in children has led in great part to this error. The trip to the mountains, if a location is well selected, is likely to be, and usually is, in summer a real benefit. But then, the physician should know something of the reputation of the particular locality to which he sends his patient. To illustrate:—suppose a patient afflicted with phthisis is sent to the White Mountains, and in company or alone, he reaches that region, and we will assume that he settles down at the "Profile House," or at any portion of the hills on their eastern slope, or immediate vicinity, and the result is almost certain to be unfavorable, since constant showers and violent changes of temperature are transpiring throughout the entire summer. If, however, a moderate elevation, away from the immediate influence of the mountains, out of the range of the frequent showers, with a southwest exposure of landscape, where the cool westerly winds have play, decided advantage will come to the sufferer. It would not likely be at once perceptible, but a gradual toning up of the system might be looked for, with an improvement of the general health. Indeed, any change to either the sick or overworked, for that matter, who are able to withstand the fatigue of a journey, is of benefit, even if the climate and location are not improved, as it is well known that a change of scene is a relief and recreation to the mind, which often plays an important part in the recovery of invalids. We all remember the story of the prisoner who had been condemned to suffer death, and at the appointed hour was led blindfolded to the dissecting hall, where were assembled the physicians who were to conduct the experiment. Being duly disrobed and placed, he was informed that an artery was to be opened, and left to bleed till life expired. An incision in the flesh at the back of the neck was made, as a mere feint, and warm water allowed at the same moment to trickle slowly down his shoulder and back, when, in a brief time, spasms set in, and death ultimately followed.

This gives a clear view of the will power inhering in the mental man, and its wonderful influence on the body. Sudden news of misfortune, or great attacks of fear, have produced instant prostration and bodily suffering, and these cases occur so frequent that all within the range of an ordinary life are familiar with them.

An English author speaks of the potent power of the mind over the body, and declares that the act of coughing can be, very often, wholly restrained by mere force of will. This should not be lost sight of by any who are attacked with colds or bronchial troubles, or even in the incipient stages of lung difficulties; as thereby they may lessen the inflammation, and defer the progress of the disease. We have seen people, who, having some slight irritation in the larynx, have, instead of smothering the reflex action, vigorously scraped their throats, and coughed with a persistence entirely unwise, inducing inflammation, from which they might date, perhaps, their subsequent bronchial troubles. It is not in coughs alone that the will exerts a mastery. In a case of fever, by which an elder brother was brought very low, scarce expected by either his friends or physician to survive, a neighbor calling, was allowed to enter the sick-room. The patient was too ill to take much notice of the visitor, and the visitor likely felt that what he might say would not effect the result, and, being rough in manners and coarse of speech, bawled out, in a loud tone, that "he wouldn't give much for his (the patient's) chances," and stalked out of the room. Happening to be present, and fearing the effect of this ill-bred visitor's remark, we drew near the bedside to hear the prostrate invalid whisper out that he was determined to live, if only to spite the old fellow. His recovery seemed to date from that event, and in a few weeks he was in possession of good health.

Consumption is divided into several classes; the more common forms are the inflammatory, the hereditary, the dyspeptic, and the catarrhal. There are others, but these suffice for purposes of brief mention of the leading characteristics of all cases.

The inflammatory is often the more difficult of management than that of the others, as its attack is violent and prostrating to such a degree as to render the usual aids of exercise and diet out of the question, for the most part. Long journeys, for any purpose, are to be avoided, though removals from the immediate sea-coast, to some dry, sandy section in the interior, within a hundred miles or so, is advisable. The robust and strong are equally subject to this class of consumption. Contracting a violent cold, such as might be taken when in a state of excitement and great perspiration in a ball-room or at a fire, and without sufficient protection pass out into the chilling air, inflammation of the lungs immediately takes place, and the chances are great of either a fatal termination of life or a shattered constitution.

The hereditary class are more frequent, and, by proper treatment of themselves, many may attain to a comparatively long life, and be able to do much of valuable service, if their employment takes them out in the open air. Of course many, inheriting this disease and having enfeebled constitutions, cannot be saved, let what will be done, and it is probably a wise provision that they are not. Consumptives should be careful to remember their great responsibility in forming alliances whereby this terrible evil is perpetuated. There should be some law enacted prohibiting the marriage of confirmed cases of scrofula, consumption, and insanity, even though complete recovery be had, as frequently happens in these difficulties.

The dyspeptic cases are numerous, and arise usually from general debility, caused by insufficient or unwholesome diet, close apartments, a too sedentary life, long depression of spirits, coupled with, perhaps, uncleanliness and irregularities, all contributing to this result. These can all be relieved, and many fully restored, if taken in season, by a counter course of living.

The catarrhal forms of consumption are more difficult to treat, and, in numberless instances, baffle all medical skill, and that is very trifling, which can be applied directly to the seat of trouble. Repeated "colds in the head," taken and neglected, become by-and-by confirmed, and pass from the rank of common colds to that of chronic catarrh. Indeed, catarrh is no more or less than a chronic cold in the head; but after the lapse of time, and this may vary in different persons, from one to a score or more of years, it assumes a more virulent character, involving, perhaps, the whole of the breathing apparatus. Its encroachments are insidious, and often are lightly considered, but the general tendency of all cases of catarrhal affections is to the lungs. Sometimes this approach is by a sudden leap, in consequence, probably, of a fresh stock of "cold," from the mucous membranes of the nasal organs to the lungs, and we have in such cases known one of the most eminent physicians of the country to declare, when examinations were made at this juncture, that "catarrh had nothing to do with it." This but illustrates the fallibility of men, and we should never be surprised when confronted with any fresh testimony tending to confirm this truth.
