CHAPTER I THE ENGINE LATHE—TURNING AND BORING OPERATIONS The standard “engine” lathe, which is the type commonly used by machinists for doing general work, is one of the most important tools in a machine shop, because it is adapted to a great variety of operations, such as turning all sorts of cylindrical and taper parts, boring holes, cutting threads, etc. The illustration shows a lathe which,... more...

They caught up with him in Belgrade. The aliens had gone by then, only a few shining metal huts in the Siberian tundra giving mute evidence that they had been anything other than a nightmare. It had seemed exactly like that. A nightmare in which all of Earth stood helpless, unable to resist or flee, while the obscene shapes slithered and flopped over all her green fields and fair cities. And the... more...

CHAPTER I. Geology defined—Compared to History—Its relation to other Physical Sciences—Not to be confounded with Cosmogony. Geology is the science which investigates the successive changes that have taken place in the organic and inorganic kingdoms of nature; it inquires into the causes of these changes, and the influence which they have exerted in modifying the surface and external structure of... more...

You can't be too suspicious when security is at stake. When everybody who is after a key military job wears a toupee, it is obviously a bald case of espionage. A job as laboratory technician with the Army Weapons Development Center carried about as much prestige as a bat boy in a World Series. George Fisher was a laboratory technician. He was a shy but likeable fellow, a diligent worker and... more...

INTRODUCTION Writings of the first Quakers, even minor writings, often kindle in us today an ardor to seek what they sought and to find what they found. The excellent book by Luella M. Wright entitled "The Literary Life of the Early Friends, 1650-1725" is a pleasant and convenient introduction to these numerous and often lengthy productions of which 2600 have been listed for the first 75 years.... more...

I THE ART OF ARCHITECTURE One of the advantages of a thorough assimilation of what may be called the theosophic idea is that it can be applied with advantage to every department of knowledge and of human activity: like the key to a cryptogram it renders clear and simple that which before seemed intricate and obscure. Let us apply this key to the subject of art, and to the art of architecture in... more...

Preface After the Turkish War (1877-1878) I made a series of travels in the Orient. From the little remarkable Balkan peninsula, I went across the Caucasus to Central Asia and Persia, and finally, in 1887, visited India, an admirable country which had attracted me from my earliest childhood. My purpose in this journey was to study and know, at home, the peoples who inhabit India and their customs, the... more...

Intellectual advance occurs in two ways. At times increase of knowledge is organized about old conceptions, while these are expanded, elaborated and refined, but not seriously revised, much less abandoned. At other times, the increase of knowledge demands qualitative rather than quantitative change; alteration, not addition. Men's minds grow cold to their former intellectual concerns; ideas that... more...

ONE of the most delightful books in my father's library was White's "Natural History of Selborne." For me it has rather gained in charm with years. I used to read it without knowing the secret of the pleasure I found in it, but as I grow older I begin to detect some of the simple expedients of this natural magic. Open the book where you will, it takes you out of doors. In our broiling... more...
