The administration of a house is to call for a higher training in mechanics. Education is giving much more of this now than formerly and will answer the demand for still more. The girls of the country, where this education is needed far more even than in the city, must be prepared to answer this need. We cannot be expert in the new housekeeping unless we have some comprehension of the chemical processes that constantly go on under our hands. One young woman took for her master's degree a study of the bacterial flora found in spoiled canned peas and string beans. She found that there are some organisms that only grow all the better after they have been boiled one hour. She found that the strongest acids do not inhibit the growth of some other kinds. She has been a good year working on that theme. If she should include one or two other kinds of spoiled foods her work would extend over another year. How many kinds of bacterial life are there? How many fruits, vegetables, foods of all sorts, are made the home of these various kinds? What processes will protect each kind from becoming harmful to human life? How many hours will it take to show that certain processes will render each variety a safe food? How many young students must give years to the business of finding out what we may use and what we may not? How long will it take us to realize that the detail of preparing the food for the table is a great scientific study, one deserving our highest expertness, meriting our highest honors, to those who work in the laboratory of the university and to those who labor in the laboratory of the house? Every young woman should consider herself a licensed observer; she should watch every process to see what she may learn of nature's secrets, that she may compare it with what she has read and thus make additions to the sum of knowledge that may be beneficial to all. It is not alone because foods have as close a connection with our well-being that we should study them. They have in themselves an extraordinary fascination. The daily and hourly companion of the worker in the household should be the magnifying-glass. The dissecting microscope is a form of magnifier that is especially adapted for household use and should be within the reach of every one. To get into the habit of putting all foods to the test of this infallible little instrument gives one a great feeling of safety and comfort. Every bag of oatmeal should be examined, all cereals, especially cornmeal, all products that have been kept in any storehouse, should be thus tested. If all the women of the country would use the magnifying-glass on everything that comes into the house, and promptly reject what is not perfectly clean, the level of good health and long life would rise suddenly by perceptible degrees among our people.
