by applying pressure on the side of the wound nearest the heart. 1 

 Thus if the finger is cut deeply and the blood jets forth, a 

 strong cord or a handkerchief should be tied loosely about 

 the wrist, a wad of paper, or a pebble being placed directly 

 beneath the knot and over the artery. A pencil or piece 

 of wood should then be run through the loop, and the knot 

 should be twisted until the blood flow is stopped by the pres- 

 sure. When blood flows evenly from a wound, it is an in- 

 dication that a vein has been cut, and the pressure should 

 be applied in a similar way on the side away from the heart. 

 If unable to decide whether an artery or a vein has been 

 cut, put the bandage directly over the cut. 2 



Bleeding from the nose may usually be stopped by holding 

 the head erect, and by applying cold water to the bridge of 

 the nose or to the back of the neck. 



1 Every pupil should practice the method of applying a bandage 

 in accordance with the directions given in this section.
