FROST-BITTEN FEET AND EARS.
Sometimes when a boy uses his skates too long, or he is exposed for a good while to bitterly cold weather, his feet or ears become frost-bitten. When this mishap takes place, he is apt to do the very thing he ought not to do.
He must not approach a fire, enter a warm room, nor use warm water or clothing. When any part of the body is frozen, snow should be constantly applied to it. If no snow is at hand, the coldest water that can be obtained must be used with cloths, until the frozen member is gradually thawed out.
SLIGHT CUTS AND WOUNDS.
All boys use jack-knives, and now and then inflict cuts upon themselves. As a rule, these do not amount to much, and only require to be washed with cold water and bound up with a clean rag; but, if a vein or artery is severed, there is great danger.

HOW TO TREAT A BLEEDING ARTERY.
If an artery is cut, the blood will be bright red, and will come out in jets, corresponding with the throbbing of the heart. As the arteries take the blood from the heart, the proper thing to do is to press the thumb strongly upon the artery just above the wound. Then a handkerchief should be knotted around the arm or leg, as the case may be, above the hurt; a stick placed under the bandage, and twisted about until the flow of blood is stopped. This will answer until the surgeon can be brought.
