Yet there is one unchanging friend who stays
To cheer the passage into Winter's gloom—
The redbreast chants his solitary lays,
A simple requiem over Nature's tomb,
So, when the Spring of life shall end with me,
God of my Fathers! may I find a changeless Friend in thee!
WINTER
The trees are leafless, and the hollow blast
Sings a shrill anthem to the bitter gloom,
The lately smiling pastures are a waste,
While beauty generates in Nature's womb;
The frowning clouds are charged with fleecy snow,
And storm and tempest bear a rival sway;
Soft gurgling rivulets have ceased to flow,
And beauty's garlands wither in decay:
Yet look but heavenward! beautiful and young
In life and lustre see the stars of night
Untouch'd by time through ages roll along,
And clear as when at first they burst to light.
And then look from the stars where heaven appears
Clad in the fertile Spring of everlasting years!
EXERCISE, AIR, AND SLEEP
The generality of people are well aware of the vast importance of exercise; but few are acquainted with its modus operandi, and few avail themselves so fully as they might of its extensive benefits. The function of respiration, which endues the blood with its vivifying principle, is very much influenced by exercise; for our Omniscient Creator has given to our lungs the same faculty of imbibing nutriment from various kinds of air, as He has given to the stomach the power of extracting nourishment from different kinds of aliment; and as the healthy functions of the stomach depend upon the due performance of certain chemical and mechanical actions, so do the functions of the lungs depend upon the due performance of proper exercise.
Man being an animal destined for an active and useful life, Providence has ordained that sloth shall bring with it its own punishment. He who passes nearly the whole of his life in the open air, inhaling a salubrious atmosphere, enjoys health and vigour of body with tranquillity of mind, and dies at the utmost limit allotted to mortality. He, on the contrary, who leads an indolent or sedentary life, combining with it excessive mental exertion, is a martyr to a train of nervous symptoms, which are extremely annoying. Man was not created for a sedentary or slothful life; but all his organs and attributes are calculated for an existence of activity and industry. If therefore we would insure health and comfort, we must make exercise—to use Dr. Cheyne's expression—a part of our religion. But this exercise should be in the open air, and in such places as are most free from smoke, or any noxious exhalations; where, in fact, the air circulates freely, purely, and abundantly. I am continually told by persons that they take a great deal of exercise, being constantly on their feet from morning till night; but, upon inquiry, it happens, that this exercise is not in the open air, but in a crowded apartment, perhaps, as in a public office, a manufactory, or at a dress maker's, where twenty or thirty young girls are crammed together from nine o'clock in the morning till nine at night, or, what is nearly as pernicious, in a house but thinly inhabited. Exercise this cannot be called; it is the worst species of labour, entailing upon its victims numerous evils. Good air is as essential as wholesome food; for the air, by coming into immediate contact with the blood, enters at once into the constitution. If therefore the air be bad, every part of the body, whether near the heart or far from it, must participate in the evil which is produced.
It is on this account that exercise in the open air is so materially beneficial to digestion. If the blood be not properly prepared by the action of good air, how can the arteries of the stomach secrete good gastric juice? Then, we have a mechanical effect besides. By exercise the circulation of the blood is rendered more energetic and regular. Every artery, muscle, and gland is excited into action, and the work of existence goes on with spirit. The muscles press the blood-vessels, and squeeze the glands, so that none of them can be idle; so that, in short, every organ thus influenced must be in action. The consequence of all this is, that every function is well performed. The stomach digests readily, the liver pours out its bile freely, the bowels act regularly, and much superfluous heat is thrown out by perspiration. These are all very important operations, and in proportion to the perfection with which they are performed will be the health and comfort of the individual.
There is another process accomplished by exercise, which more immediately concerns the nervous system. "Many people," says Mr. Abernethy, "who are extremely irritable and hypochondriacal, and are constantly obliged to take medicines to regulate their bowels while they live an inactive life, no longer suffer from nervous irritation, or require aperient medicines when they use exercise to a degree that would be excessive in ordinary constitutions." This leads us to infer that the superfluous energy of the nerves is exhausted by the exercise of the body, and that as the abstraction of blood mitigates inflammations, in like manner does the abstraction of nervous irritability restore tranquillity to the system. This of course applies only to a state of high nervous irritation; but exercise is equally beneficial when the constitution is much weakened, by producing throughout the whole frame that energetic action which has been already explained.
A debilitated frame ought never to take so much exercise as to cause fatigue, neither ought exercise to be taken immediately before nor immediately after a full meal. Mr. Abernethy's prescription is a very good one—to rise early and use active exercise in the open air, till a slight degree of fatigue be felt; then to rest one hour, and breakfast. After this rest three hours, "in order that the energies of the constitution may be concentrated in the work of digestion;" then take active exercise again for two hours, rest one, and then dine. After dinner rest for three hours; and afterwards, in summer, take a gentle stroll, which, with an hour's rest before supper, will constitute the plan of exercise for the day. In wet or inclement weather, the exercise may be taken in the house, the windows being opened, "by walking actively backwards and forwards, as sailors do on ship-board."
We now come to the consideration of air. Pure air is as necessary to existence as good and wholesome food; perhaps more so; for our food has to undergo a very elaborate change before it is introduced into the mass of circulating blood, while the air is received at once into the lungs, and comes into immediate contact with the blood in that important organ. The effect of the air upon the blood is this: by thrusting out as it were, all the noxious properties which it has collected in its passage through the body, it endues it with the peculiar property of vitality, that is, it enables it to build up, repair, and excite the different functions and organs of the body. If therefore this air, which we inhale every instant, be not pure, the whole mass of blood is very soon contaminated, and the frame, in some part or other speedily experiences the bad effects. This will explain to us the almost miraculous benefits which are obtained by change of air, as well as the decided advantages of a free and copious ventilation. The prejudices against a free circulation of air, especially in the sick chamber, are productive of great evil. The rule as regards this is plain and simple: admit as much fresh air as you can; provided it does not blow in upon you in a stream, and provided you are not in a state of profuse perspiration at the time; for in accordance with the Spanish proverb—
"If the wind blows on you through a hole
Make your will, and take care of your soul."
but if the whole of the body be exposed at once to a cold atmosphere, no bad consequences need be anticipated.
A great deal has been said about the necessary quantity of sleep; that is, how long one ought to indulge in sleeping. This question, like many others, cannot be reduced to mathematical precision; for much must depend upon habit, constitution, and the nature and duration of our occupations. A person in good health, whose
