WILLIAM WALLACE CAMPBELL
EVERY serious student of nature asks, sooner or later: What was the origin of the stars? What has been their history? And what does the future hold in store for them? In harmony with our experience is the belief that all matter in the universe is endowed with the property of obeying certain fundamental laws, such as: every particle of matter attracts every other particle; a hotter body radiates its heat energy to a cooler body; gases expand indefinitely unless resisted by gravitation or other effective force.

PEOFESSOR RICHARD SWANN LULL
LAST summer it was the writer's privilege to lead a small expedition from Yale to the fossil fields of the west in search for the relics of bygone creatures to add to the already extensive collections owned by the university. Our purpose was not solely that of collecting, however, but to get data concerning the distribution in time of certain of the ancient faunas, hoping thereby not only to increase the sum of our knowledge, but to date more accurately some of the wealth of forms collected by the pioneer expeditions which, under the leadership of Professor Marsh, penetrated the unknown west in the early seventies.

FOUR POINTS IN THE INDICTMENT OF THE SMOKE NUISANCE
MELLON INSTITUTE OF INDUSTRIAL RESEARCH, UNIVERSITY OF PITTSBURGH

JOHN O'CONNOR
IN all papers and talks concerning the smoke nuisance, it has become customary to refer to the economic cost of the nuisance both to the public and to the smoke makers. This is the indictment which is supposed to strike home. When a speaker on this subject says The abolition of the smoke nuisance, unlike many other social nuisances against which outcry has been, would result in direct and immediate gain both to the public at large and to those who are chiefly responsible for the nuisance itself, he feels that he has said the last word.

PRESIDENT P. R. KOLBE
IN these modern days of municipal extravagance, of crowded city budgets, and of frantic legislative attempts to control undue rates of taxation in our centers of population, any new source of expenditure is almost pre-fated to encounter the shrug of suspicion—the stony stare of hostility.

M. E. HAGGERTY
REVOLUTIONS are a part of our modern world. Men have come to look upon them as natural moments in national life. So much experience have the western nations had with social upheavals and the reversal of political practises that they have learned how to revolute without war or violence.

BIOLOGICAL EFFECTS OF RACE MOVEMENTS

CHANCELLOR DAVID STARR JORDAN
THERE are but three ways in which the force of a race or a nation may be permanently lowered : ( 1 ) Emigration, the transfer of stronger elements to other regions; (2) immigration, filling up the gaps with people of lower native ability or energy; (3) war, the destruction of the virile and soldierly.

PROFESSOR LYNN THORNDIKE
PROBABLY ninety-nine out of every hundred educated persons would be surprised to learn that there was any such thing as natural science in the middle ages. Lest I seem to impute too much ignorance to my present audience, perhaps I should lower the ratio to nine persons out of ten.

A HISTOIRY OF FIJI
PART III

[no value]
DR. ALFRED GOLDSBOROUGH MAYER
OF all established customs in Fiji the most odious was cannibalism, yet it was always tabu for women and the lower classes, and the custom was extensively practised only by the chiefs and warriors. It is possible that in Fiji it was primitively a religious rite and did not originate in time of famine, or through motives of mere revenge.

THE POPULAR SCIENCE MONTHLY, since its establishment in 1872 by J. W. Youmans and the firm of D. Appleton and Company, has endeavored to perform two functions which are somewhat distinct. On the one hand, it has aimed to popularize science, and, on the other hand, to publish articles reviewing scientific progress and advocating scientific, educational and social reforms.
