come in. The living rooms should toe thoroughly ventilated and 

 well treated. We should not keep out all the fresh air and try to 

 delude ourselves with the idea that it requires more coal and wood 

 to make the room comfortable again. Many are ignorant of the 

 fact that it requires more heat to warm impure air than to warm pure 

 air. Open the doors and windows, if only for a few moments, and 

 have fresh air to breathe instead of breathing over and over again 

 the same air. Sleeping rooms and beds require daily ventilation. 

 This is a matter of importance we should never neglect. Pure, 

 fresh air is a blessing we should not banish from our homes. 



Great care should be taken in the selection of our food — the qual- 

 ity and quantity. Aiming to select such foods as are nourishing 

 and digestible, then have them well cooked and well baked. We 

 cannot have fixed rules for diet. Every man should be his own 

 judge as to what and how much he should eat. He must, however, 

 bear in mind that the amount of food and exercise must be balanced. 

 Great mental and physical work can be borne well if hygienic prin- 

 ciples of diet, exercise, etc., be attended to. Milk has so often been 

 the carrier of contagion that everything which in any way could 

 aifect it should be carefully examined. In order to do so we must 

 begin at the barn, and if I am allowed to suggest a few words to 

 the other side of the house, would say, keep the barn, the surround- 

 ings, and above all, the cow stables, as clean as possible. Animals 

 as well as man must have pure air and clean surroundings. Next 

 comes the dairy. The milk cans and even the water they are washed 

 in should receive attention. 



Were the laws of health and physiology better understood, more 

 sought after, how great would be the effect. It would almost 

 change the face of the earth. Let us hope that matters of such 

 great moment may not always be considered of less importance than 

 the languages of extinct nations, or the unimportant facts of dead 

 historv. 



NATURE STUDY. 



By MISS M^KY SHEARER, SaxUm. Pti. 



Unlike most school subjects, nature study has not been reduced 



to a conventional form — the same for every town and every school. 



Nature rings endless changes upon herself; she has her seashore,
