In the North it is common to travel in skates on the gulfs and rivers; and, with a favourable wind, they go faster than vessels. It is a kind of flight, for they only touch the ground in a very slight thin line. As to feats in skating, we are told, that the Frieslander, who is generally a skilful skater, often goes for a long time at the rate of fifteen miles an hour. In 1801, two young women, going thirty miles in two hours, won the prize in a skating race at Groningen. In 1821, a Lincolnshire man, for a wager of 100 guineas, skated one mile within two seconds of three minutes. DANGERS IN SKATING. If the chest be irritable, it is neither salutary nor easy to skate against the wind. In countries where these exercises are general, inflammations of the chest are very common in winter. Skating sometimes exposes to much danger. If the skater find that he cannot get away from rotten ice, he must crawl over it on his hands and knees, in order to reduce his weight on the supporting points. If he fall on it at length, he must roll away from it towards ice more firm. If he fall into a hole, he must extend his arms horizontally over the edges of the unbroken ice, and only tread water, till a ladder or a plank is pushed towards him, or a rope is thrown for his hold. TREATMENT RECOMMENDED IN THE CASE OF DROWNED PERSONS. CAUTIONS.--1. Lose no time. 2. Avoid all rough usage. 3. Never hold the body up by the feet. 4. Nor roll the body on casks. 5. Nor rub the body with salt or spirits. 6. Nor inject tobacco-smoke or infusion of tobacco. RESTORATIVE MEANS IF APPARENTLY DROWNED.--Send quickly for medical assistance; but do not delay the following means. I. Convey the body carefully, with the head and shoulders supported in a raised position, to the nearest house. II. Strip the body, and rub it dry; then wrap it in hot blankets, and place it in a warm bed in a warm chamber. III. Wipe and cleanse the mouth and nostrils. IV. In order to restore the natural warmth of the body: 1. Move a heated covered warming-pan over the back and spine. 2. Put bladders or bottles of hot water, or heated bricks, to the pit of the stomach, the arm-pits, between the thighs, and to the soles of the feet. 3. Foment the body with hot flannels; but, if possible, 4. Immerse the body in a warm bath, as hot as the hand can bear without pain, as this is preferable to the other means for restoring warmth. 5. Rub the body briskly with the hand; do not, however, suspend the use of the other means at the same time.
