BROKEN GLASS.
BLEEDING FROM FACE. FIRST AID HINTS. Broken glass is a serious menace in all road accidents. The face, particularly, is liable to cuts from flying pieces, as it is not protected t>v clothing. The glass, having very sharp edges, inflicts incised cuts which bleed very freely. If, states a contributor to a motor journal,, an artery has been severed the blood will spurt out, often to quite a considerable distance, with each beat of the heart. It will also bo bright red in colour. Speed in stopping this kind of bleeding is imperative. Death, through loss of blood, rnav ensue within a few minutes.
Lay the patient on his back. In this position the ho'art beats slowest. If the face has been cut raise tho head a little. This lessens the force of the blood to the affected part. Remove any glass left in the wound, but do not probe for any you cannot see. The cut artery must be closed by pressing it against a nearby bone. Use the thumbs for this, but do not dig the nails into the patient's flesh. Exert pressure at a convenient spot between Ihe cut and heart. Bleeding from Neck. Bleeding from the neck can be stopped in this way by pressing the carotid artery back against the spine. The thumbs should be adjacent to one another. The carotid artery can be found on each side of tho windpipe, midway between the ear and the shoulder. To exert greater pressure with the thumbs, the hands may be placed round the back of the head. Bleeding from the chin, lips, cheeks, and the outside of the nose can best be stopped by pressing the facial artery. This can be located iu the hollow of. tho lower jaw, about two fingers' breadth in front, and on each side of the angle of the jaw. The temporal artery, just in front of the ear, if pressed, will stop bleeding from tlie forehead. The services of a doctor are esseutial in all cases, but, pending his arrival, the cut may be washed with an antiseptic solution, such as iodine in cold water, and covered with a soft, dry dressing of white lint. If Cut Not Serious. If tho cut is not so serious, however, and the bleeding can be stopped tho dressing may be padded with cot-ton-wool and kept in position by means of a bandage. The patient can then be taken to a doctor. Tass the bandage across the forehead and round tho head for a cut on the forehead. Be sure that the bandage is placed just below the widest part of the head, otherwise it will easily slip off. For other parts of the face strips of adhesive jilaster can probably be etnployed more advantageously. If the cuts are very extensive a mask can be made out; of lint and applied right over the face. Holes should be cut for the eyes and. nose. Stimulating drinks, such us hot tea and coffee, should not be given until the bleeding has been definitely stopped, otherwise the increased action of the heart will bring on further bleoding. When, however, the bleeding has been finally stopped a stimulating drink is desirable. Also, loosen all tight clothing on tho patient, keep him warm and encourage sleep. ORPHANS' OUTING. MORE CARS NEEDED. More cars are needed to enable thfc annual outing for the orphans of Christchurch 011 April 2nd to be a success, and those who are willing to assist with the loan of cars aro requested to communicate as soon as possible with the secretary of the Canterbury Automobile Association (Mr J. 8. Hawkcs). So far tho use of 49 cars has been' promised, but another 50 cars will be required. The orphans will be called for at the respective homes, and the cars will be assembled at Latimer square in roadiness to move off for the picnic ground at the Pines, Kairaki Beach, at 2 p.m. WIND RESISTANCE. CAUSE OF COLOSSAL WASTE. At last tho world is awakening to the colossal waste that is continually going 011 because of tho drag on all last transportation media 011 account ol wind resistance. The importance of this will be better realised when it is mentioned . that wind resistance increases as the square of tho velocity. It is really only during the past low years that much attention has been directed to this important phase of travelling at speed, and then it was the last comer in the field of ' transportation that brought about the intensified research that is now focused on the development of all high speod vehicles. ' Until recently all experiments to obtain performance data were conducted with models in wiijdstreain tunnels at physical laboratories, but even with the utmost eare inaccuracies wore possible, and the data often incomplete. At Langley (U.S.A.),a giant sized testing tunnel has been built, which is 434Jft long and 222 ft wide, and is of .the open-throat type.. Two four bladed propellers, each driven by 4000 h.p. electric motors, produce wind velocities up to 115 m.p.h. Provision is made to subject planes or vehicles to any angle of attack. Air forces are read directly from selfregisteriufr scale*. This outsize in testing tunnels cost £'200.000, and indicates how alive eneineers aro becoming to tho desirability of reducing waste attributable to wind resistance. A CAUSE OF SHIMMY. Front wheel shimmy sometimes is ! caused or aggravated' bv loosq wheels, ! Such looseness is easily detected by I jacking up the front wheels and shak- [ ipg them, making sure that the excess I movement is not the king pins. Normal looseness in the wheels can be taken up by tightening the nuts on the ends of tlie axles. This is work for the careful motorist, since it is apparent that the bearings can easily be cramped. The wheel should spin around freely. Just because it does not stop with the tyre valve down does not mean that it is cramped, however, because wheels 011 many of the newer cars are perfectly balanced. If the wear is m the bearings themselves it is a good plan to clean them and repack with a heavier grade of grease- Tllis Ilot only will coni PO n sato for a small amount of wear, but also onsure better lubrication.
