It is not impossible that some useful information may be conveyed by this book. Should these pages prove of such service, their cost in labor is most cheerfully donated. This volume is composed of a series of articles which appeared in a Trade Journal, covering a period of two years from 1887 to 1889. It must be accepted as but a brief history of an industry long identified with Baltimore. Thanks are due the Librarian of the Maryland Historical Society and Mr. B. R. Sheriff for favors in lending rare and valuable old City directories; also to the many citizens who kindly aided and assisted in the search for needed information. The Author.

Chapter: 10 | Listen: 1

“In this little volume are brought together a number of sketches and memoranda, illustrating the history of discovery, and the lives and labours of inventors and explorers, not of our own country alone, but of others, for knowledge is of no country, but of all. The object of the collector has been rather to present the popular than the strictly scientific side of his subject, to furnish materials of interest and amusement, as well as instruction; and if now and then he has been tempted to stray into bye-paths of anecdote and gossip, excuse may readily be found in the fact that the private life of our men of science, often singularly noble and full of character, is apt to be altogether obscured by the brilliancy of the results of their secret and silent toil. This volume will have served its purpose, if it excites an appetite for fuller and deeper inquisition into the sources of British greatness and of modern civilization.” Since there are no chapter or other divisions of these anecdotes, the reader has chosen to read entries for about thirty minutes per section. There is an index of topics in the printed book available on gutenberg.org. (From Book Introductory Note and David Wales)     [chương_files]

John Kenlon became a New York City firefighter in 1887, and was appointed Fire Chief in 1911. In 1913, he wrote this authoritative book surveying the history of fire-fighting from ancient Rome to 20th-century New York. The first part of the book explores the evolution of fire-fighting techniques in various countries and the development of equipment and organization, and describes several famous historical fires and how they were fought. The remainder of the book discusses in greater detail some particular types of fires confronting an urban fire department in 1913, such as hotel, theater, factory, hospital, and school fires, sea port fires, and skyscraper fires. The author also emphasizes the need for high pressure water delivery systems, sprinkler systems, modern apparatus, and proper training for firefighters, and touches on the role of underwriters and salvage corps. – Summary by Maria Kasper     [chương_files]

In the following pages we shall peep into the history of typical companies in Great Britain, the United States, and elsewhere; consider the various forms of traction, signals, and other mechanical appliances connected with the working of a railway; notice the effects of railway communication on a country for its peaceful development, or its conquest in war; and make the tour of a typical locomotive factory. These and other matters have been treated as simply as may be, but with sufficient fullness to give the reader a fair idea of what the railway really is, how it has been made, and what the future may have in store for it. – Summary by from the preface.     [chương_files]

Chapter: 20 | Listen:

The electric telegraph, together with the railway-train and the steamship, constituted the three most conspicuous features of late 19th century civilization. Indeed, it may be truly said that the harnessing electricity to the service of man for human communication has effected a change in political, commercial, and social relations, even more complete than that wrought by steam locomotion. This is the story of how the electric telegraph cable was laid across the floor of the Atlantic from Newfoundland to Ireland. – Summary by modified from the introduction     [chương_files]

“… this war was not one of mere destruction. It set men to thinking as they had never thought before. It intensified their inventive faculties, and as a result, the world is richer in many ways. Lessons of thrift and economy have been taught us. Manufacturers have learned the value of standardization. The business man has gained an appreciation of scientific research. The whole story is too big to be contained within the covers of a single book, but I have selected the more important and interesting inventions and have endeavored to describe them in simple language for the benefit of the reader who is not technically trained.” Bond was the sometime editor of Scientific American magazine.

Chapter: 23 | Listen: 1

Since being sworn in on February 6, 1986, the Commission has been able to conduct a comprehensive investigation of the Challenger accident. This report documents our findings and makes recommendations for your consideration. Our objective has been not only to prevent any recurrence of the failure related to this accident, but to the extent possible to reduce other risks in future flights. Each member of the Commission shared the pain and anguish the nation felt at the loss of the seven brave Americans in the Challenger accident on January 28, 1986. The nation’s task now is to move ahead to return to safe space flight and to its recognized position of leadership in space. There could be no more fitting tribute to the Challenger crew than to do so. (Summary from the letter of commission)     [chương_files]
