In the fermentation of corn, for making malt liquors or ardent spirits, a large quantity of carbonic acid is generated, and workmen who heedlessly descend into the vats to cleanse them, are very often suffocated. The trial by a lighted candle should never in such cases be omitted. In the burning of lime there is a very large proportion of carbonic acid set free; and poor persons who are tempted to sleep on the platform of a lime-kiln for the sake of the warmth it affords, are sometimes suffocated by the vitiated air they breathe.
The air, so far as regards its influence on health, is modified in a very important manner by causes which are not so positively known and measured as those we have hitherto examined. The spreading of odours through the air, whether they be the “spicy gales of Araby the blest,” or the more unwelcome indications of putrescent matter, takes place by means of quantities of substances so small as to defy the powers of detection we possess. Many diseases, it is well established, arise from the formation and diffusion through the air of peculiar poisons in amazingly small quantity. Thus ague is produced by a specific poison generated in marshes. These poisons resemble other ordinary poisons, inasmuch as we can decompose them, and thus destroy their power. The chemical substance chlorine decomposes almost every vegetable or animal material that it touches. Thus it destroys all colours, and is hence of the greatest use in bleaching; it also destroys all atmospheric poisons, and, consequently, in hospitals and in private houses it is used to disinfect or prevent the spreading of disease, by decomposing the material which conveys it through the air.
For change of air we therefore, with reason, go to the country when we can; but whether to the sea side or to the interior, to Enniskerry or Kingstown, is not dependent on the nature of the air. Wherever the invalid finds most amusement, and agreeable occupation which does not fatigue; wherever the beauty of scenery, and the society of those to whom the heart is bound in ties of mutual esteem and love, present to the mind of one harassed by intense exertion of thought, or broken down by disease of body, a relief in admiration of the wisdom and goodness of his Creator, and in sympathy and kindliness towards his fellow men, the atmosphere is clearest; the bracing, enlivening influence of the pure country air is the most sensible, and the mind and body are most effectually restored to the condition of perfect health.
Ireland for Ever! and Kilmainham to the Devil!—
Mr Egan, better known as “Bully Egan,” held the chairmanship of Kilmainham at the time that the government were using their utmost endeavours to pass the Act of Union, and, of course, expected to be deprived of his office if he should oppose it. However, when the time for the division had arrived, his love of country preponderating over his love of self, he voted against the measure, exultingly exclaiming, “Ireland for ever! and Kilmainham to the devil!
PERSEVERANCE.
Perseverance in the steady pursuit of a laudable and lawful object, is almost a sure path to eminence. It is a thing which seems to be inherent in some, but it may be cultivated in all. Even those children who seem to be either indolent like the sloth, or changeful as the butterfly, by the skilful training of a watchful parent, may be endowed with the habit of perseverance. The following anecdotes may aid in illustrating to youth the nature and value of this virtue. The celebrated Timour the Tartar, after a series of the most brilliant victories, was at length conquered and made captive. Though confined in a prison, whose massive walls and thick iron bars discouraged every attempt to escape, he still strove at each chink and crevice to find some way of deliverance. At length, weary and dispirited, he sat down in a corner of his gloomy prison, and gave himself up to despair. While brooding over his sorrows, an ant, with a piece of wood thrice as large as itself, attracted his attention. The insect seemed desirous to ascend the perpendicular face of the wall, and made several attempts to effect it. But after reaching a little elevation, it came to a jutting angle of the stone, and fell backward to the floor. But again, again, and again the attempt was renewed. The monarch watched the struggles of the insect, and in the interest thus excited forgot his own condition. The ant persevered, and at the sixtieth trial surmounted the obstacle. Timour sprang to his feet, exclaiming, “I will never despair—perseverance conquers all things!”
A similar anecdote is told of Robert Bruce, the restorer of the Scottish monarchy. Being out on an expedition to reconnoitre the enemy, he had occasion to sleep at night in a barn. In the morning, still reclining his head on a pillow of straw, he beheld a spider climbing up a beam of the roof. The insect fell to the ground, but immediately made a second essay to ascend. This attracted the notice of the hero, who with regret saw the spider fall a second time from the same eminence. It made a third unsuccessful attempt. Not without a mixture of concern and curiosity, the monarch twelve times beheld the insect baffled in its aim; but the thirteenth essay was crowned with success. It gained the summit of the barn; and the king, starting from his couch, exclaimed, “This despicable insect has taught me perseverance! I will follow its example. Have I not been twelve times defeated by the enemy’s superior force? On one fight more hangs the independence of my country!” In a few days his anticipations were fully realised, by the glorious result, to Scotland, of the battle of Bannockburn.
A few years since, while travelling in an adjacent state, I came to a little valley, surrounded by rocky and precipitous hills. In that valley was a single house. It was old, and, by its irregularity of form, seemed to have been built at various periods. It was, however, in good condition, and bespoke thrift and comfort. Not a shingle was missing from the roof, no dangling clapboards disfigured its sides, no unhinged blinds swung idly in the wind, no old hats were thrust through the windows. All around was tidy and well-conditioned. The woodhouse was stored with tall ranges of hickory, the barns were ample, and stacks of hay without declared that it was full within. The soil around, as I have said, was rocky, but cultivation had rendered it fertile. Thriving orchards, rich pastures and prolific meadows, occupied the bed of the valley and the rugged sides of the hills. I was struck with the scene, and when I reached a village at the distance of two or three miles, I made some inquiries, where I learnt the story of the proprietor. He was originally a poor boy, and wholly dependent upon his own exertions. He was brought up as a farmer, and began life as a day labourer. In childhood he had read that “procrastination is the thief of time.” He did not at first understand its meaning, and pondered long upon this desperate thief who bore the formidable title of Procrastination. It was at length explained to him; but the struggles he had made to comprehend the adage fixed it deep in his mind. He often thought of it, and, feeling its force, it became the ruling maxim of his life. Following its dictates with inflexible perseverance, he at length became proprietor of the little valley I have described. Year by year it improved under his care, and at the period of which I am speaking, he was supposed to be worth at least twenty thousand dollars.
