CHAPTER I. HOW DIAMOND CUT DIAMOND, AND HOW THE SPARKS FLEW. The windows are all wide open, and through them the warm, lazy summer wind is stealing languidly. The perfume of the seringas from the shrubbery beyond, mingled with all the lesser but more delicate delights of the garden beneath, comes with the wind, and fills the drawing-room of The Place with a vague, almost drowsy sense of sweetness. Mrs.... more...

Bart Neely was fighting the hypo. They'd slipped that over on him. Now he had to struggle to keep his brain ready for plan B. The alternate plan. He nodded feebly at his reflection in the mirror over the white enamel dresser. This throat-trouble wasn't going to lick him. He lay back on the cool white pillow. Medical men always thought theirs was the final answer; well, psychologists like... more...

CHAPTER I ACTION OF STEAM ENGINES A steam engine is a device by means of which heat is transformed into work. Work may be defined as the result produced by a force acting through space, and is commonly measured in foot-pounds; a foot-pound represents the work done in raising 1 pound 1 foot in height. The rate of doing work is called power. It has been found by experiment that there is a definite... more...

SANDWICHES Sandwiches may be made from one of three or four kinds of bread; whole wheat bread, Boston brown or oatmeal bread, white bread and rye bread made into square, deep loaves; in fact, all bread used for sandwiches should be made especially for the purpose, so that the slices may be in good form, and sufficiently large to cut into fancy shapes. The butter may be used plain, slightly softened or... more...

THE window of Randolph Reed's office was almost completely covered by magnificent gold block lettering. This to any one who had time and ability to read it—and the former was more common in the community than the latter—conveyed the information that Reed dealt in every kind of real estate, from country palaces to city flats. The last item was put in more for the sake of symmetry than accuracy,... more...

Duncan MacLeod hung up the suit he had taken off, and sealed his shirt, socks and underwear in a laundry envelope bearing his name and identity-number, tossing this into one of the wire baskets provided for the purpose. Then, naked except for the plastic identity disk around his neck, he went over to the desk, turned in his locker key, and passed into the big room beyond. Four or five young men,... more...

he rifle lay comfortably in his hands, a gleaming precision instrument that exuded a faint odor of gun oil and powder solvent. It was a perfect specimen of the gunsmith's art, a semi-automatic rifle with a telescopic sight—a precisely engineered tool that could hurl death with pinpoint accuracy for better than half a mile. Daniel Matson eyed the weapon with bleak gray eyes, the eyes of a hunter... more...

In studying the kinds of mammals known from Kansas, I had occasion to examine a series of Perognathus flavus from the western part of the state. Comparisons of these specimens with topotypes of named subspecies revealed that the specimens from Kansas belong to a heretofore undescribed subspecies which ranges through western Nebraska, eastern Colorado, western Kansas, and western Oklahoma. This... more...

Section I THE history of mankind is the history of the attainment of external power. Man is the tool-using, fire-making animal. From the outset of his terrestrial career we find him supplementing the natural strength and bodily weapons of a beast by the heat of burning and the rough implement of stone. So he passed beyond the ape. From that he expands. Presently he added to himself the power of the... more...

CHAPTER I ON RAYS PROPAGATED IN STRAIGHT LINES s happens in all the sciences in which Geometry is applied to matter, the demonstrations concerning Optics are founded on truths drawn from experience. Such are that the rays of light are propagated in straight lines; that the angles of reflexion and of incidence are equal; and that in refraction the ray is bent according to the law of sines, now so well... more...
