Book Description
Excerpt from Lightships and Lighthouses Romances innumerable have been woven around the flaming guardians of the coast, but it is doubtful whether any purely imaginative work is so fascinating and absorbing as the plain unvarnished narrative of how some famous lightship or lighthouse has been brought into existence. And the story of construction is equalled in even, way by that relating to the operation and maintenance of the light, against all odds, for the guidance of those who have business upon the ocean. This volume is not a history of lightships and lighthouses; neither is it a technical treatise. Rather my object has been to relate how the difficulties, peculiar and prodigious, have been overcome by the builders in their efforts to mark some terrible danger-spots, both on the mainland and isolated sea-rocks. While the lines of the lightship and lighthouse are familiar to all, popular knowledge concerning the internal apparatus of the building or ship is somewhat hazy. Therefore I have explained, with technicalities simplified as much as possible, the equipment of the tower and vessel, and the methods whereby both visual and audible warnings are given. The very latest developments in this field of engineering and science are incorporated, so as to render the subject as comprehensive as possible within the limits of a single volume. In the compilation of this book I have received the heartiest assistance from those who are prominently associated with the work of providing adequate aids to navigation.

Book Description
Excerpt from Lighthouses and Lightships of the United States The lighthouse and the lightship appeal to the in terest and better instinct of man because they are symbolic of never-ceasing watchfulness, of steadfast endurance in every exposure, of widespread helpful ness. The building and the keeping of the lights is a picturesque and humanitarian work of the nation. But this work is not all romance, as, unseen by the passing mariner, and back of the lighthouse and ship and buoy, there must be a great engineering and business machine with its endless contracts, plans, specifications, appointments, the routine of office and depot and ship and light-station. Scarcely a day passes, however, that there does not gleam in the mass of dry routine a fact of interest, an act of brav cry, a risk cheerfully taken to aid another, a record of long and faithful service, an improvement of light or of fog signal, of vessel or of lighthouse, an historic record of the past, or a photograph of the present.
