Not illustrated. 1909 edition. Excerpt: ...manholes about 75 feet apart, where iron pipe and terra-cotta single-duet are joined, as just described. The conduit crosses a Fio. 12.--Subway crossing at Twenty-third and Market Streets; twenty-six wrought-iron pipes (one tier buried). large filtration main at this point, and lies so close to the surface of the street that iron pipe was necessary at the crown. For each duct in the section one 20-foot length of iron pipe was used, and the run then continued with terra-cotta. On top of the conduit was placed a 6-inch concrete slab reinforced with J-inch and %-inch rods to withstand surface loads and prevent crushing of the ducts (Fig. 11).. A shallow run of conduit across the top of the subway at Twentythird and Market Streets, consisting of twenty-six ducts, wroughtiron pipe, furnishes another example of the joining of iron to terracotta (Fig. 12). It also illustrates the method of changing section between manholes, from four horizontal tiers, six and seven ducts wide, to the standard section, four ducts wide (Fig. 13). Subsidiary Ducts. Connections to buildings or poles consist, as a rule, of one duct of creosoted wood. They are generally laid at a less depth than the main run, the average cover being from 18 inches to 24 inches. Drainage is always toward the manhole, where possible, not toward the building or pole, so as to prevent water from entering the building or collecting at the base of the pole. When it is not possible to have the pipe slope continuously toward the manhole, provision for drainage is made by perforating the duct at its lowest point. Connections terminating in buildings are carefully sealed at both ends, as soon as laid, to exclude gas or water. For connections to distributing boxes on buildings or poles a 2-inch...

"This book is not as much about answers as it is about questions. It is not intended to be a guide to the built world around us, but a spur to encourage us all simply to be more inquisitive. The first half of the book shows the struggle that goes into making ubiquitous objects do their jobs and the triumph that engineers experience when the objects succeed, and it tries to reveal some of the thought processes behind their work. In the second half of the book, stories unfold. In these stories, pieces of engineering and design are deployed in the world to carry out their useful functions, beyond the protective reach of the people who created them." -foreword.

A classic work in the field of practical and professional ethics, this collection of nine essays by English philosopher and educator Henry Sidgwick (1838-1900) was first published in 1898 and forms a vital complement to Sidgwick's major treatise on moral theory, The Methods of Ethics. Reissued here as Volume One in a new series sponsored by the Association for Practical and Professional Ethics, the book is composed chiefly of addresses to members of two ethical societies that Sidgwick helped to found in Cambridge and London in the 1880s. Clear, taut, and lively, these essays demonstrate the compassion and calm reasonableness that Sidgwick brought to all his writings. As Sidgwick explains in his opening essay, the societies he addressed aimed to allow academics, professionals, and others to pursue joint efforts at reaching "some results of value for practical guidance and life." Sidgwick hoped that members might discuss such questions as when, if ever, public officials might be justified in lying or in breaking promises, whether scientists could legitimately inflict suffering on animals for research purposes, when nations might have just cause in going to war, and a score of other issues of ethics in public and private life still debated a century later. This valuable reissue returns Practical Ethics to its rightful place in Sidgwick's oeuvre. Noted ethicist Sissela Bok provides a superb Introduction, ranging over the course of Sidgwick's life and career and underscoring the relevance of Practical Ethics to contemporary debate. She writes: "Practical Ethics, the last book that Henry Sidgwick published before his death in 1900, contains the distillation of a lifetime of reflection on ethics and on what it would take for ethical debate to be 'really of use in the solution of practical questions.'" This rich, engaging work is essential reading for all concerned with the relationship between ethical theory and. practice, and with the questions that have driven the study of professional ethics in recent years.
