The most important food product which has a direct relationship to this class of diseases is milk. In a large city like New York it will remain impossible to solve the milk problem, despite the splendid efforts of the Health Department and the members of the medical profession, until the city itself shall establish milk depots and ice stations where safe milk, and ice to keep it safe, may be obtained at a nominal cost, or free, if the parents cannot afford to buy it. We, therefore, must recognize that the vast majority of children to-day are taking milk that is not suited to them, that is really not fit as a food for children. The mothers do not know this and no steps are taken to render the milk more safe for them to feed to their children. These mothers are willing to do what is essential in the interest of their children, but they do not know what should be done. These people cannot afford a physician or a nurse to teach them, nor do they even know that their methods are wrong or that they need any instruction. We must carry the information and the explanation to them. We must show them the need for a change of methods. This is the work for those charitably disposed women who desire some worthy purpose in life, who really wish to do some real good. All the equipment they need is good common sense. They will tell these mothers why it is necessary to pasteurize the milk before feeding it to the baby. They will show how to keep the nursing bottles clean, and the nipples sweet and fresh. They will instruct them how to dress the baby in the hot weather and impress them with the need of giving it all the cool, fresh air possible. In short, they will gain the confidence and the good will of these mothers in a tactful and diplomatic way, and they will tell them all they know in language which they will understand regarding the care of the baby. In every city in the country this work is needed and is waiting for the missionaries who will volunteer. To teach mothers the need for boiled water as a necessary drink for baby and older children is alone a worthy avocation. To impress upon one of these willing but ignorant mothers the absolute necessity for washing her hands before she prepares her baby's food, that she must keep a covered vessel in which the soiled napkins are placed until washed, that she should frequently sponge her baby in the hot weather, and explain thoroughly why these are important details, is a work of true religious charity. They should be specially taught to immediately discontinue milk at the first sign of intestinal trouble, to give a suitable dose of castor oil and to put the child on barley water as a food until the danger is passed. They should be taught to know the significance of a green, watery stool, they should know that is the one danger signal in the summer time that no mother can ignore without wilfully risking the life of her baby. They should be taught to prepare special articles of diet when they are needed.
