lete after the visit he
made to Orange to pose for the motion pictures in the earliest days of
their development. On looking up under the second gallery at this end
is seen a great roll resting in sockets placed on each side of the room.
This is a huge screen or curtain which may be drawn down to the floor to
provide a means of projection for lantern slides or motion pictures, for
the entertainment or instruction of Edison and his guests. In one of
the larger alcoves is a large terrestrial globe pivoted in its special
stand, together with a relief map of the United States; and here and
there are handsomely mounted specimens of underground conductors and
electric welds that were made at the Edison Machine Works at Schenectady
before it was merged into the General Electric Company. On two
pedestals stand, respectively, two other mementoes of the works, one
a fifteen-light dynamo of the Edison type, and the other an elaborate
electric fan--both of them gifts from associates or employees.

In noting these various objects of interest one must not lose sight
of the fact that this part of the building is primarily a library,
if indeed that fact did not at once impress itself by a glance at the
well-filled unglazed book-shelves in the alcoves of the main floor. Here
Edison's catholic taste in reading becomes apparent as one scans the
titles of thousands of volumes ranged upon the shelves, for they include
astronomy, botany, chemistry, dynamics, electricity, engineering,
forestry, geology, geography, mechanics, mining, medicine, metallurgy,
magnetism, philosophy, psychology, physics, steam, steam-engines,
telegraphy, telephony, and many others. Besides these there are the
journals and proceedings of numerous technical societies; encyclopaedias
of various kinds; bound series of important technical magazines; a
collection of United States and foreign patents, embracing some hundreds
of volumes, together with an extensive assortment of miscellaneous books
of special and general interest. There is another big library up in
the house on the hill--in fact, there are books upon books all over the
home. And wherever they are, those books are read.

As one is about to pass out of the library attention is arrested by an
incongruity in the form of a cot, which stands in an alcove near the
door. Here Edison, throwing himself down, sometimes seeks a short rest
during specially long working tours. Sleep is practically instantaneous
and profo
