The extensive collection of Mexican mammals made by Mr. J. R. Alcorn for the University of Kansas Museum of Natural History contains fourteen piñon mice from lava rocks eight miles northeast of the city of Durango, Mexico. These mice are all much darker than the piñon mice, Peromyscus truei gentilis, of adjoining areas in Durango and Zacatecas and show a superficial resemblance to the widespread P.... more...

CHAPTER I The Wrecked Space-Ship When I came to, it was dark; so dark that the night seemed all but fluid with black pigment. Breathing was difficult, but in spite of that, however, I felt exhilarated mentally. Also I felt strong, stronger than I ever had in my life before. I tried to raise my hands, and found that I was handcuffed. I lay sprawled out on a sharply canted floor of metal, and from... more...

PREFACE I The superficial, no doubt, will mistake this little book for a somewhat laborious attempt at jocosity. Because, incidentally to its main purpose, it unveils occasional ideas of so inordinate an erroneousness that they verge upon the ludicrous, it will be set down a piece of spoofing, and perhaps denounced as in bad taste. But all the while that main purpose will remain clear enough to the... more...

Yesterday morning this thing happened to me: I was reading the New York Times and my eyes suddenly fell upon one word, and that word rang a little bell in my memory, “Kirkwall!” The next moment I had closed my eyes in order to see backward more clearly, and slowly, but surely, the old, old town––standing boldly upon the very beach of the stormy North Sea––became clear in my mental vision.... more...

I. THE SUCCESSORS OF NEWTON IN ASTRONOMYHEVELIUS AND HALLEYSTRANGELY enough, the decade immediately following Newton was one of comparative barrenness in scientific progress, the early years of the eighteenth century not being as productive of great astronomers as the later years of the seventeenth, or, for that matter, as the later years of the eighteenth century itself. Several of the prominent... more...

HISTORY My theme is history. It is an old subject, which has been discoursed about since Herodotus, and I should be vain indeed if I flattered myself that I could say aught new concerning the methods of writing it, when this has for so long a period engaged the minds of so many gifted men. Yet to a sympathetic audience, to people who love history, there is always the chance that a fresh treatment may... more...

Chapter One: Education as a Necessity of Life 1. Renewal of Life by Transmission. The most notable distinction between living and inanimate things is that the former maintain themselves by renewal. A stone when struck resists. If its resistance is greater than the force of the blow struck, it remains outwardly unchanged. Otherwise, it is shattered into smaller bits. Never does the stone attempt to... more...

ust looking at Ellaby, you could tell he was going places. He was five feet nine inches tall and weighed a hundred and fifty pounds. He had an I. Q. of ninety-eight point five-seven, less than four hundredths off the mode. His hair was mousey and worn slightly long for a man, slightly short for a woman. Back in High Falls, where he was born, he was physically weaker than sixty percent of the men but... more...

It was his greatest pride in life that he had been a soldier—a soldier of the empire. (He was known simply as "The Soldier," and it is probable that there was not a man or woman, and certain that there was not a child in the Quarter who did not know him: the tall, erect old Sergeant with his white, carefully waxed moustache, and his face seamed with two sabre cuts. One of these cuts, all... more...
