The demand for cheap goods and the intense strain produced by commercial competition has induced many dealers and manufacturers to adulterate their products. This practice enables them to satisfy the buyer and outwit their competitors, not to speak of the immediate financial advantage

Municipal Hygiene - Part II - Milk

It is the purpose of this paper to help popularize the scientific facts that have been discovered by the research laboratories which are controlled and fostered by our national government and individual States of the Union, and by the laboratories of the denominational institutions of higher education. Vast sums of money are spent each year to maintain such work. No one can question their efficiency or practical value. Such knowledge is not prized as highly as it should be, nor are the discoveries as thoroughly known as they should be. The bulletins that are issued from the various stations are within the reach of everyone, they are absolutely free. Like streams that have their origin in the ice fields of remote mountains, they come in gentle cascades to satisfy the thirsty and revive life, and give hope for better and higher life. Doth not Wisdom cry? and Understanding put forth her voice? She crieth at the gates, at the entry, at the coming, at the doors

Presidential Address - Influence of Modern Science in the Formation of Ideals

Allow me to congratulate you on the completion of another year\u27s successful and profitable work. Self-imposed scientific effort brings its own reward to every earnest soul in search of truth. The acquisition of new knowledge is both fascinating and stimulating. In proportion as we get knowledge at first hand, just in that proportion is the fascination and the stimulation increased, and our acquirements become a part of our being

Cedar River at Cedar Rapids, Iowa

For thirty-seven years we have noted with regret the gradual increase in the pollution of our river, in fact the increase has been quite rapid during recent years. During that time the inhabitants on the banks have increased three-fold while the amount of pollution that is put into the river has increased probably three-thousand-fold. A third of a century ago the Chlorine as Chlorides was three parts per million, the normal amount for unpolluted water in this region; now it is ten. A half a century ago when the Cedar Rapids water works were first built, raw water was put into the mains and for twelve years used for drinking water by a large per cent of the inhabitants

By-products, damaged feeds and nontraditional feed sources for swine

"In Missouri, corn and soybean oil meal are the principal feed ingrents used in formulating swine rations. Rations using corn and soybean meal remain the standard to which other ingredients are compared. COnsiderable use is made of other ingredients, however, depending on cost."--First page.John C.
