VENTILATION, HEAT/ AND CLOTHJ,NP ;)> ,, , 



Lying upon the damp ground is dangerous, for it may 

 make our clothes damp. This will cool one part of the 

 body more than another and cause us to take cold. 



Bundling the neck and ears while the legs and feet 

 have no more covering than usual makes the head tender 

 and often causes us to take cold. Then, since our feet 

 are cold, we are almost certain to take cold. We had 

 better cover the feet more warmly and not wrap up the 

 head and neck. 



We ought always to wear enough clothing to keep us 

 warm. It is a mistake to think that we can get used 

 to the cold by going without proper clothes. We shall be 

 more liable to take cold and shall make ourselves more 

 tender than ever. But we ought not to wear so much 

 clothing that we are too warm.

 parts of the body. When the blood does not flow well 

 through a part, that part becomes cold. If we wear tight 

 garters or shoes, the blood cannot flow through the feet 

 as it should. Then we have cold feet. Tight clothing 

 of any kind makes us cold. 



193. Paper clothing. If paper were only stronger, it 

 would make one of the best kinds of clothing. When 

 we have too little clothing we can keep warm by putting 

 a newspaper around the body under the coat or waistcoat. 

 At night a few newspapers between the quilts will make 

 us much warmer. 



194. Cold-blooded animals. Some animals, like frogs 

 and snakes, breathe but little. They do not produce 

 enough heat to make themselves much warmer than the 

 air. On cold days they are dull and sluggish. In winter 

 they are stiff and do not move, but lie buried in the mud 

 or earth. Yet they breathe enough through their skins to
