laces, columns, towers, cathedrals, bridges,
viaducts, churches, and buildings of every description which the genius
of man has constructed; and as these are all described in chronological
order, according to the eras to which they belong, they form a connected
narrative of the development of architecture, in which the history and
progress of the art can be authentically traced. Care has been taken to
popularize the theme as much as possible, to make the descriptions plain
and vivid, to render the text free from mere technicalities, and to
convey a correct and truthful impression of the various objects that are
enumerated.

=Lighthouses and Lightships.=

LIGHTHOUSES AND LIGHTSHIPS. By W.H.D. ADAMS. With sixty illustrations.
One volume 12mo. _Printed on tinted paper_ $1 50

The aim of this volume is to furnish in a popular and intelligible form
a description of the Lighthouse _as it is_ and _as it was_, of the rude
Roman pharos, or old sea-tower, with its flickering fire of wood or
coal, and the modern Lighthouse, shapely and yet substantial, with its
powerful illuminating apparatus of lamps and lenses, shining ten, or
twelve, or twenty miles across the waters. The author gives a
descriptive and historical account of their mode of construction and
organization, based on the best authorities, and revised by competent
critics. Sketches are furnished of the most remarkable Lighthouses in
the Old World, and a graphic narration is presented of the mode of life
of their keepers.
