Persons, moreover, who pursue active employments, frequently object to undertaking journies, from an opinion that their daily occupations are sufficient to produce all the salutary effects we expect from artificial exercise. It will be highly necessary to correct this mistake, by assuring such persons that, however useful the habitual exercise of an active, or even a laborious employment may be to preserve health, it must always be exchanged for one which excites new impressions, both upon the mind and body, in every attempt to restore the system from that debility which is connected with pulmonary consumption.
As travelling is often rendered useless, and even hurtful in this disease, from being pursued in an improper manner, it will be necessary to furnish our patients with such directions as will enable them to derive the greatest benefit from their journies. I shall, therefore, in this place, mention the substance of the directions which I have given in writing for many years to such consumptive patients as undertake journies by my advice.
1. To avoid fatigue. Too much cannot be said to enforce this direction. It is the hinge on which the recovery or death of a consumptive patient frequently turns. I repeat it again, therefore, that patients should be charged over and over when they set off on a journey, as well as when they use exercise of any kind, to avoid fatigue. For this purpose they should begin by travelling only a few miles in a day, and increase the distance of their stages, as they increase their strength. By neglecting this practice, many persons have returned from journies much worse than when they left home, and many have died in taverns, or at the houses of their friends on the road. Travelling in stage-coaches is seldom safe for a consumptive patient. They are often crowded; they give too much motion; and they afford by their short delays and distant stages, too little time for rest, or for taking the frequent refreshment which was formerly recommended.
2. To avoid travelling too soon in the morning, and after the going down of the sun in the evening, and, if the weather be hot, never to travel in the middle of the day. The sooner a patient breakfasts after he leaves his bed the better; and in no case should he leave his morning stage with an empty stomach.
3. If it should be necessary for a patient to lie down, or to sleep in the day time, he should be advised to undress himself, and to cover his body between sheets or blankets. The usual ligatures of garters, stocks, knee-bands, waistcoats, and shoes, are very unfriendly to sound sleep; hence persons who lie down with their clothes on, often awake from an afternoon's nap in terror from dreams, or in a profuse sweat, or with a head-ach or sick stomach; and generally out of humour. The surveyors are so sensible of the truth of this remark, that they always undress themselves when they sleep in the woods. An intelligent gentleman of this profession informed me, that he had frequently seen young woodsmen, who had refused to conform to this practice, so much indisposed in the morning, that, after the experience of a few nights, they were forced to adopt it.
Great care should be taken in sleeping, whether in the day time or at night, never to lie down in damp sheets. Dr. Sydenham excepts the danger from this quarter, when he speaks of the efficacy of travelling on horseback in curing the consumption.
4. Patients who travel for health in this disease should avoid all large companies, more especially evening and night parties. The air of a contaminated room, phlogisticated by the breath of fifteen or twenty persons, and by the same number of burning candles, is poison to a consumptive patient. To avoid impure air from every other source, he should likewise avoid sleeping in a crowded room, or with curtains around his bed, and even with a bed-fellow.
5. Travelling, to be effectual in this disease, should be conducted in such a manner as that a patient may escape the extremes of heat and cold. For this purpose he should pass the winter, and part of the spring, in Georgia or South-Carolina, and the summer in New-Hampshire, Massachusetts, or Vermont, or, if he pleases, he may still more effectually shun the summer heats, by crossing the lakes, and travelling along the shores of the St. Laurence to the city of Quebec. He will thus escape the extremes of heat and cold, particularly the less avoidable one of heat; for I have constantly found the hot month of July to be as unfriendly to consumptive patients in Pennsylvania, as the variable month of March. By these means too he will enjoy nearly an equable temperature of air in every month of the year; and his system will be free from the inconvenience of the alternate action of heat and cold upon it. The autumnal months should be spent in New-Jersey or Pennsylvania.
In these journies from north to south, or from south to north, he should be careful, for reasons before mentioned, to keep at as great a distance as possible from the sea coast. Should this inquiry fall into the hands of a British physician, I would beg leave to suggest to him, whether more advantages would not accrue to his consumptive patients from advising them to cross the Atlantic ocean, and afterwards to pursue the tour which I have recommended, than by sending them to Portugal, France, or Italy. Here they will arrive with such a mitigation of the violence of the disease, in consequence of the length of their sea voyage, as will enable them immediately to begin their journies on horseback. Here they will be exposed to fewer temptations to intemperance, or to unhealthy amusements, than in old European countries. And, lastly, in the whole course of this tour, they will travel among a people related to them by a sameness of language and manners, and by ancient or modern ties of citizenship. Long journies for the recovery of health, under circumstances so agreeable, should certainly be preferred to travelling among strangers of different nations, languages, and manners, on the continent of Europe.
6. To render travelling on horseback effectual in a consumption, it should be continued with moderate intervals from six to twelve months. But the cure should not be rested upon a single journey. It should be repeated every two or three years, till our patient has passed the consumptive stages of life. Nay, he must do more; he must acquire a habit of riding constantly, both at home and abroad; or, to use the words of Dr. Fuller, “he must, like a Tartar, learn to live on horseback, by which means he will acquire in time the constitution of a Tartar[34].”
