twinkly eyes, who has new method
for treating cirrhosis OF the acoustic3
Up to recent date. whenever an
architect put UP an auditorium or
something that was a poem from the
outside, but acousticaly was so i'm
possible as to make straightaway talk
sound like the last m0uthings OF John
Mccullough, there We're only couple
Of cures known. One of them was t0
line the inside Of the upper part Of the
auditorium with felt and clutter it al
up with fatty upholstered furniture
and draperies and soft stuff Of all
kinds, on the theory that it would soak
up the superfluous sound Another
method was to string a bunch OF
wires across the top Of the aulitorl.
um, This was in the hope that the
wires would strain the sound, letting
all the extra rumbllng and jumbling
filter through and go out the sky
lights. and bounce the useful noises
back at the audience.
These two methods do not amount
to much, but they comprise the whole
list The felt and furniture hang,
ings and other things used as sound
sponges made a building fearfully In

the air made it look like telegraph

But Mr. Harper has a brand new
method that has worked fine he says.
He discovered that sopnd doesn't trav-
Ell in waves like light, but jumps along
by magnetic impulse, and he has fig
lred out, too, that IL doesn't make
in building just so long as its shape
IS correct. This discovery simply de-
jtroys the regulation theory, and many
earned professors occupying chairs
n colleges have amused themselves,
Mr. Harper says, by jumping up and
