Not illustrated. 1916 edition. Excerpt: ...that this group of microscopic plants, in its relation to bread making (from one kind of grain) adds to the wealth and happiness of the world, and ministers to one of the most fundamental needs of our physical being, while in its relation to brewing (the formation of alcohol from another kind of grain) it contributes to one of the greatest sources of poverty, misery, and crime. The use of yeast in bread making dates from prehistoric ages. It is mentioned in old testament history as early as the patriarchal age. It is of interest also to reflect that in the various great migrations of the human race, this little plant must have been preserved and transported with as much care as domestic animals. In such a movement as the colonization of a new continent, as, for example, North and South America, and Australia, provision must have been made for maintaining the supply of yeast for the making of bread. BACTERIA 289. Extent of Their Influence.--The study of bacteria, the smallest of all known plants, has become so extensive as to form a separate science, bacteriology; and it will not be possible here to more than suggest in outline the numerous important ways in which these tiny plants affect our daily lives. In fact their discovery has practically revolutionized our method of living in many ways. Fig. 225.--Louis Pasteur, founder of the science of bacteriology. Modern methods of sanitation and hygiene, public and private, modern house furnishing, as, for example, the substitution of bare floors with rugs in place of carpets, modern views of disease and methods of treating it, and the technique of innumerable industries, both agricultural and manufacturing, have all been profoundly modified Fig. 226.--Tumors on a black walnut (Juglans nigra); more
