APPARATUS TO BE INSTALLED IN ALL
wARsHIPS AND SHORE STATIONS.

Washington, July S.-W'reess telegraphic equip
ment for the entire navy, including Offices at all
shore stations and apparatus on every ship is to
be Installed as rapidly as possible. under plans
made by Admiral Bradford and approved by Secre-
tary Moody. Orders have been issued and are now
being carried out at the New-York Navy Yard to
mt all ships in commission for the apparatus by
setting up wooden masts above the fighting tops,
which will carry wires from yardarms 1S5 feet
above the water line. and poles of similar height
have been ordered put in position at the New-York
yard, on the Navesink heights and at Norfolk and
Key West. Poles with crossarms and wires
already placed in the Naval Academy grounds at
Annapolis and in the Washington Navy Yard. and

subject and regardless of exclusive claims by vari

associated with him have become convinced that

returning with eight sets of instruments, with
which his petty officers have made themselves
familiar. The success of the mission was largely
due to Commander F. NJ Barber. U. S. N, retired,
who has been in Europe watching the development
of wireless telegraphy and progress along other
lines valuable to the navy for several years.
