The danger of children wading in the Ashburton River and the possibility of them being swept, out of their depth was exemplified the other afternoon in a swimming pool between William street and the East Bolt (reports the Guardian). A child, six years of age. who was one of a picnic party, when paddling near the bank, was caught by the current and carried into deep water. Noticing the child’s plight the mother went to her assistance, but soon found herself in difficulties. Ultimately a man rescued both mother and child, who on being brought to lan! quickly recovered, and suffered no ill-effects beyond a severe fright. A Xmas treat for the children—Ron .Tolly Crystals, the purest made. No old stock. Ask your grocer for them.

As a rule the pressure is about two and a-ha.lf tons, or 55601 b to every square inch of the surface of the barrel. A locomotive, drawing an express train weighing 300 tons and carrying hundreds of passengers, requires a nrcssuro of less than 2CO!b to the square foot to drive it; yet to kill a single rabb't or partridge we must use a force 25 times as great. In the case of the riflo, the pressure driving the bullet is more than IS tons to each square inch. The actual push against, the head of the bolt, is about four tons. Naturally this immense driving force produces a terrific speed. The bullet is sent on its way from the rifle at no less than 2700 ft a second. When the 15in gun of a battleship is fired, the pressure in the* breech is more than 20 tons to the square inch. The shell of such a gun weighs a ton, but the enormous force behind it sends it on its way at more than 3000 ft a second. The greatest velocity over reached was that of the Big Berthas which bombarded Peris from a distance of 70 miles. Their shells travelled at the rate of 5000 ft a second—or more than 3400 miles an hour—and ’he pressure in the gun must have boon over 30 tons to tho square b«sn.
