PROFESSOR ROBERT DEC. WARD
FAR and wide, the world over, we find a popular belief in an influence of forests upon climate, especially upon rainfall. This is not difficult to explain. Take our own experience, for example. On a summer day we leave the hot, sunny road and walk along a narrow forest path.
WE learn from “Dichtung und Wahrheit” that when the young Goethe came home ill from the University of Leipzig in 1768, he fell under the influence of a physician who claimed to have found an infallible panacea which he did not dare use because he was afraid of legal action against him.
THERE are about forty species of grapes in the world, more than half of which are found in North America. Few other plants on this continent grow wild under such varied conditions and over such extended areas. Thus, wild grapes are found in the warmer parts of New Brunswick; on the shores of the Great Lakes; everywhere in the rich woodlands and thickets of the North and Middle Atlantic States; on the limestone soils in the mountainous parts of Kentucky, Tennessee and the Virginias; and they thrive in the sandy woods, sea plains and reef-keys of the South Atlantic and Gulf States, where a single vine of the Scuppernong often clambers over trees and shrubs for a hundred feet or more.
THE wide-spread ignorance of the various means employed by the federal government to promote the well-being of its citizens is nowhere better exemplified than in the common ignorance of the functions and important work of the Public Health Service.

IT is quite generally believed by those who have studied American morbidity and mortality tendencies that there has been a marked increase in recent years in the death rate from chronic diseases of the important and hardest worked organs of the body.
THE LIFE INSURANCE COMPANY AS A DYNAMIC IN THE MOVEMENT FOR PHYSICAL WELFARE

THE average careless liver, although he may be perfectly willing to swallow some “magic” elixir, exhibits uneasiness tinged with suspicion when approached on the subject of prolonging his life by means of adjusting him to his environment.
THE lowest forms of life show the greatest stability in their specific characters. Any one who will examine a little pond water under the microscope will see numerous minute Protozoa belonging to different families, genera and species. Close study brings out the fact that although we regard these as very low types, they are complicated little animals, with remarkable characters.
SOME RANDOM THOUGHTS CONCERNING COLLEGE CONDITIONS
PROFESSOR JOHN J. STEVENSON
AN ever-increasing proportion of the community seems to be convinced that every youth, male or female, on American soil, has a natural right to collegiate and even to professional education at nominal or no cost. That so many have been deprived of the opportunity to acquire a college degree is one of the saddest of the world’s many tragedies; good men and women, having exhausted the joy of conscious usefulness in the ordinary philanthropic operations, find new zest in contriving methods whereby those excluded from college attendance may secure the coveted parchment with a minimum of expense and inconvenience.
