bly of the Presbyteiian church in
tho United States of Amorica to
day adopted a far-raaching recom
mendation : looking towards or
ganic union of flvo largo Protest

The proposal, made on the floor
Of tho assembly, provided for
appointment of commissions to

from the Protestant Episcopal
church, the Methodist '( Episcopal j
church, tho Methodist 'Episcopal!
Church, South, and the ' Presbyte- I
rian church of the United States,

. The action was taken tin answer
to an invitation for a commission
to consider union, extended by
the Protestant Episcopal church
at its general convention In Wash
ington in October, 1928. . Similarly
the other church bodies have had
under 'consideration the proposal
for union for some tlmo, but to

in tho . annual .report presented
"today to the .lilst- Presbyterian
general assembly- of i Walter - Irv-,
ing Clarke, national director of
publicity for the denomination.
"The business world spends. mil
lions . for publicity whoro the
church spends dollars," said Mr.
Clarke. "The church gets a. great
deal of reading spaco In tho news
papers as legitimate news. But
tho church has a message for
humanity which it could to ad
vantage express In tho large uso
of paid advertising space. Cities
of the United States upend 6,000 -000
a year for publicity to ex
ololt their attractions.
"One single brand of cigarettes
of tho many brands advertising.
appropriated 112,600.000 for this
year's advertising, ono half of
wh.chls being spent In newspapers
alone. The continued experience
of regular advertisers demonstrates
that newspapers offer the nipst
effective medium of appeal. Pio
neers in the use of tho radio ap
peal, apportion their advertising
budgets accordingly
"Tho Presbyterian publicity de
partment has faith that some day
religion will bo adequately adver
tised and will roap vast rewards
as are now accumulated by less
worthy enterprises."

Fish and game wardena operating
in tho section have had no 4 easy

practically powerless to cope with
the situation. These officers have
found tires slashed, automobile

sometimes filled with Byrup.

several streams have been depleted
by commercial fishermen and said
one commercial fisherman had

him had only beon able to catch
200 worth, Indicating how thuruly

government could take an active
hand and place the section under
Its direct care, as it has dono In

A remedy for this serious prob
