DOMESTIC SCIENCE IN ITS RELATION TO SANITARY SCIENCE. 121 



filled with dangers. Domestic Science has made the housekeeper cognizant 

 of that fact, and she knows from what sources pure water may be 

 obtained and how it may be purified, appreciating the Chinese fondness 

 for tea, since the boiled water, used in making it, saves them from drink- 

 ing the dangerously polluted water of their big cities unsterilized. Care- 

 lessness in plumbing and drainage, which constantly comes under. the 

 eye, is as much a problem of the housekeeper as of the plumber who 

 puts in the work or the one with a knowledge of sanitary science who 

 must pass judgment upon it. It is the housekeeper's problem and her 

 judgment should be sufficiently good to pass sentence. When she can 

 do so definitely, her anxious and troubled times will be lessened, even as 

 the health of the family will improve. Nature has taught us so much 

 in constantly ridding every form of life from all waste and decay; we 

 need no stronger lesson for our model. All the visible filth with which 

 we become laden in our persons and about the house can be removed and 

 fought against with definite evidence of success. The dangers attendant 

 upon their presence, if from inorganic materials, are the clogging and 

 poisoning of the skin, the ruining, by wear and tear, of clothes and other 

 materials about the house. Vegetable decay from foods, house plants 

 and old flowers, can be guarded against with vigilance and abolished 

 with care, so the dangers are not so grave as those which come from ani- 

 mal wastes. These are from the alimentaiy canal, from the lungs and 

 skins. If visible, the dangers from them are slight, for they are observed 

 and soon overcome. If not visible, such as those which come from air 

 expelled from the lungs, the dangers may lurk about with little chance 

 of being discovered until it is too late. Of these, then, one must learn 

 and know. 



The housekeeper's work is not made more difficult by a knowledge of 

 these questions, but is rather flooded with light, as she recognizes more 

 fully the efficacy of nature's aids — air, sunshine and water, the greatest 

 purifiers. The life of one who does not understand is full of troubled 

 questionings, which work itself cannot solve. The one, who through a 

 knowledge of Domestic Science, has been able to take some hold on Sani- 

 tary Science, from it receiving the answer to countless of her queries, will 

 be able to live her life with an intensified, awakened interest, her mind 

 will be alert and all her work intelligent. The results of her labors will 

 be the securing of pure, stimulating air for all the household, healthful 

 food, pure water, cleanly surroundings and the final product will be the 

 healthful body, resistant of disease. • 



Domestic Science is not an independent study, but is the aggregate of 

 all the sciences which underlie the making of the home. Its problems 

 lead in various directions, calling for much of knowledge in divers ways. 

 Many of its labors seem yet unaffected by the light of knowledge which 

 has been poured upon them. The workers are slow to understand that 

 science is necessary to them, and that it will be a valuably aid. With 

 the responsibility of many of the gravest sanitary questions in her hands, 

 the home-maker ignores the simplest laws of personal hygiene for her- 

 self and for her family. But the movement which has begun toward 

 better things is something more than a mere awakening. The science of 

 the home has made forward strides within the last quarter century. Not 

 yet universal, it will become so, when the home-makers, together with
