Induction of Electric Currents. 6. About twenty-six feet of copper wire one twentieth of an inch in diameter were wound round a cylinder of wood as a helix, the different spires of which were prevented from touching by a thin interposed twine. This helix was covered with calico, and then a second wire applied in the same manner. In this way twelve helices were superposed, each containing an average... more...

INTRODUCTION THE DECLINE AND FALL OF THE OLD ISLAMIC WORLD The rise of Islam is perhaps the most amazing event in human history. Springing from a land and a people alike previously negligible, Islam spread within a century over half the earth, shattering great empires, overthrowing long-established religions, remoulding the souls of races, and building up a whole new world—the world of Islam. The... more...

CHAPTER I. INTRODUCTION. THE NECESSITY OF FORM IN MUSIC.—So much uncertainty and diversity of opinion exists among music lovers of every grade concerning the presence of Form in musical composition, and the necessity of its presence there, that a few general principles are submitted at the outset of our studies, as a guide to individual reflection and judgment on the subject. Certain apparently... more...

INTRODUCTORY The American method of teaching the mechanical arts has some disadvantages, as compared with the apprentice system followed in England, and very largely on the continent. It is too often the case that here a boy or a young man begins work in a machine shop, not for the avowed purpose of learning the trade, but simply as a helper, with no other object in view than to get his weekly wages.... more...

INTRODUCTION The Use of Punctuation.—Punctuation is a device for marking out the arrangement of a writer's ideas. Reading is thereby made easier than it otherwise would be. A writer's ideas are expressed by a number of words arranged in groups, the words in one group being more closely connected with one another than they are with those in the next group. An example will show this grouping... more...

I THE SILENT, SUBTLE BUILDING FORCES OF MIND AND SPIRIT There are moments in the lives of all of us when we catch glimpses of a life—our life—that is infinitely beyond the life we are now living. We realise that we are living below our possibilities. We long for the realisation of the life that we feel should be. Instinctively we perceive that there are within us powers and forces that we are... more...

Before the dawn of history mankind was engaged in the study of dreaming. The wise man among the ancients was preëminently the interpreter of dreams. The ability to interpret successfully or plausibly was the quickest road to royal favor, as Joseph and Daniel found it to be; failure to give satisfaction in this respect led to banishment from court or death. When a scholar laboriously translates a... more...

Approach to the Silence Wrong thinking produces inharmony in our body, which in turn produces sickness. Our bodies sometimes are instantly re-harmonized while in the Silence. In the Silence our minds become passive, open, free and loving, at which time the Infinite Master of harmony touches the mental chords of our being and we are well. Just as the piano can be tuned, so can the mind. Man's body... more...

CHAPTER I PRELIMINARY The problem as to the understanding of the Scriptures is with some no problem at all. All we have to do is to take the narratives at their face meaning. The Book is written in plain English, and all that is necessary for its comprehension is a knowledge of what the words mean. If we have any doubts, we can consult the dictionary. The plain man ought to have no difficulty in... more...

PREFACE It seems eminently fitting and proper in this year, the fiftieth anniversary of the Proclamation of Emancipation that the Negro should give pause and look around him at the things which he has done, those which he might have done, and those which he intends to do. We pause, just at the beginning of another half century, taking stock of past achievements, present conditions, future... more...
