PROFESSOR J. B. WHITEHEAD
THE possibility of operating all classes of steam railway service by electricity has been demonstrated beyond question. Heavier trains may be hauled at higher speeds and with greater comfort to passengers, and electric locomotives may be built which surpass in power any steam locomotive which may be construeted.

THE WORK OF BOARDS OF HEALTH

DR. GEORGE A. SOPER
THE spirit of the laws by which matters of public health are administered rests upon the theory which underlies all forms of government, that is, that the state has the power to compel the ignorant, the selfish, the careless and the vicious to so regulate their lives and property that they shall not be a source of danger to others.

DR. PERLEY SPAULDING
ONE of the best known of the botanical collectors of this country who worked shortly after the middle of the last century was August Fendler. He, like numerous others, came to America from Germany in the late thirties. From 1864 to 1871 he lived at Allenton, Missouri, about thirty miles from St. Louis.

FIRE'S HAVOC A SENSELESS WASTE

F. W. FITZPATRICK
WE have reason to be proud of the phenomenal growth of our American cities, the beauty of their buildings and the vast volume of building construction that is yearly carried on in the process of that growth. But a careful analysis shows us that that great volume of building is not all growth, but is, to a very great extent indeed, the replacing of buildings that have been destroyed by fire.

THEO. F. VAN WAGENEN
SOME one has characterized the present as the “age of metals.” There are at least fifty-nine of these useful substances known to the chemist of to-day, yet if the average well-educated man was asked to name them, it is doubtful if he could enumerate more than a score.

SCIENCE AND MORALITY

PROFESSOR ALBERT P. MATHEWS
ONE of the most striking phenomena of the nineteenth century was the great rise of science and the loosening of religious ties coincident with a marked improvement in general morality. As it has for centuries been generally taught that morals depend upon religion, this phenomenon has to many appeared inexplicable.

PROFESSOR FRANK SARGENT HOFFMAN
THE most remarkable thing yet discovered about this planet is the fact that human beings exist upon it in large numbers, scattered almost everywhere over its surface, that pay homage to superterrestrial powers. But this fact, remarkable as it is, is only a portion of the truth.

JAMES P. MUNROE
HORACE MANN, speaking in 1841, said: “A practical unbelief in the power of education—the power of physical, intellectual and moral training—exists among us, as a people.” Two generations later are we still, as a people, unbelievers? We extol with fervor, with acclamation, with volubility, free schools; we pay our taxes not too unwillingly, spend an occasional session in our children's schools, help John and Mary, spasmodically and ineffectively, with their harder lessons, send them at some sacrifice to a high school or perhaps to college, and then thank God for the priceless blessing of a liberal education!

BOSTON is still the chief educational center of the country. Among its institutions for higher education, Harvard is our greatest university and the Massachusetts Institute of Technology our greatest school of technology. This year Harvard is for the first time surpassed by Columbia in the number of students, and it will soon be overtaken by several of the state universities.
