director of the show. Mr.. Lawrence
, came into radio fame through the
broadcasting Of the community sings

Mr.. Lawrence already has started

Plans Grow Rapidly.
Plans for the show are progressing
rapidly. Washingtons radio dealers
have secured more than so per cent of
the available space for exhibits. A
number of nationally known manu-
facturers of radio products also have
reserved space, and Alfred l.. Stern,
director of the show, predicts that
every inch of the $4,000 square feet
of floor space will be contracted for
by exhibitors within the next few
weeks.
Besides the manufacturers and
dealers exhibits there will be dis
plays by the various government de-
partmentS interested directly or in
directly with the development of ra-
dio. The bureau of standards, Army,
Navy and Marine Corps are making
arrangements to exhibit apparatus of
a historical nature showing the steps
the government has taken to set the
pace In the ever progressing science
of radio.

offers to, place his exhibit at radio

home city" he has agreed TO brlng
out from his laboratory for the first
time for public display that remark
able little machine that makes 1T pos
sible for pictures, movable or i'm

that the one lens in Washington may

tographic plates in as many different
cities at the same time, and at dis
