To Test Eggs by Candling. Roll a sheet of cardboard into a tube 

 or cylinder, large enough to fit down over a lamp chimney or 

 a candle. A large shoe box with the ends removed and the cover 

 fastened in place will serve as well. In the side of the tube or box 

 opposite the flame, cut a hole somewhat smaller in diameter than an 

 ordinary egg. 



Place the tube over a candle, lamp, or incandescent lamp, so that 

 the light is visible through the hole in the side of the tube. Hold 

 each egg to the opening in the cardboard, broad end up, and observe 

 it against the light. In a good fresh egg, the air space is small, 

 the yolk appears clear and round in dim outline, and the white is 

 clear. If the air space is rather large and the yolk is darkened, the 

 egg is stale. If the contents of the egg appear dark or hazy, with 

 a black spot, the egg is unfit for food. 



If one has much testing of this k;nd to do, it is better to secure 

 a candling chimney for a small sum at a poultry store. 



(c) The loss of liquid content by evaporation makes an egg lighter, 

 and so it may be tested by its specific density (p. 150). Make a 

 solution of one quart of water with two tablespoonfuls of salt. 

 A fresh egg will sink in this solution. A very stale egg will float. 

 Eggs at stages between a very fresh and a very stale egg may float 

 at various depths.

 pages 444-445 



No home, office, or school should be without a Red Cross First 

 Aid Kit. 



Do not attempt home treatment for anything but scratches or 

 shallow cuts or punctures. In case of deep cuts, accompanied by 

 severe bleeding, call a doctor immediately. Pressure on the wound 

 with a pad of aseptic gauze will retard the flow of blood until the 

 doctor can arrive. Do not use your fingers or an unclean cloth for 

 this purpose. 



If the blood comes in spurts, an artery has been cut. In this 

 event, pressure should be exerted, if possible, on the supply artery
