If blood spurts from the wound, an artery is divided; bind limb tightly above wound with India-rubber tubing, strap, handkerchief or scarf; or, bend the limb forcibly at next joint above wound; or, press flat hand or stone where blood is flowing. If blood flows freely, but does not spurt, a vein is divided; then apply same measures as in case wounded artery, but below the wound. If scalp wounded, make a pad of cloth or waste, and bandage very tightly over wound with folded pocket handkerchief. Send for a physician then.
