speed Of Q hundred lines . minute. It
moves an inch minute across the
cylinder transmitting each minute In
the form Of electric impulses q strip
Of photograph / inch wide and IL
inches long.
These electric impulses pass over
the wires from Los Angeles to re-
ceiving machines In all the other
cities in the network. When the wire
photo attendant In Los Angeles pressed
the button which set into motion the
cylinder of his sending machine, with
the picture mounted on it, he auto
matically set into motion at the same
instant all the receiving machines.
Each receiving machine has light
proof cylinder around which is
clamoed an unexposed negative.
When the electric impulses from the
sending machine in Los Angeles reach
the receiving machines. they are re-
converted, again by q photo-electric
cell, into lignt beams. In each ma
chine these light beams strike the
negative, as it revolves on the cylin-
der in perfect synchrony with the
picture at the other end Of the wire,
and expose 1t in exact proportion to
the amount Of light reflected from
the picture On the distant-sending
cylinder.
Exact Reproduction.

IF the original picture was II by II

minutes to send 1t from Los Angeles
to all the other cities on the wire
photo network. The picture received
is exactly the same size as the picture
that was sent.
Pictures have been sent by wire

The inauguration of wirephotos on
this first day of a new year marks
an epoch not only because wirephotos
represent so remarkable an advance
toward perfection of transmission: not
only because of the increased speed
at which pictures can be sent over
the network which was opened today:
not only because the wirephoto circuit
reached into IS cities; but most Of all
because wirephoto has been created
and is maintained by and for news
papers as their own servant; because
it is theirs "a hours a day and seven
days a week: because for the first time
paralleled networks Of leased wires
carry side by side the story and the
picture into newspaper Offices.
Other Uses Possible.
Nor is wirephoto limited to trans
mission of pictures by wire. 1t can
and will bring to newspapers all man.
