MAPPING FOREST
Forest Service Plans AeriaI
Survey Of Timber Lands
and Power Sites.

Experiments in the practicability OF
using an aeroplane for reconnaissance
work in Southeastern Alaska will be
undertaken within the next 10 days
by the Forest Service, according to
an announcement made here today by
District Logging Engineer B. f,
Heintzelman. The expercent will be
made by Aviator Roy L. Jones Of
Ketchikan. using his flying boat and
accompanied by ]. C. bort, in charge
of the Forest Services waterpower
survey activities.
This will be the first attempt ever
made to locate possible waterpower
sources and sites by aerial surveys
according to Mr. Heintzelman Fire
patrol by aviators and aerial timber
mapping have been successfully car
ried out. The first in the United
States and the latter on a substan-
tial scale in the province of Quebec
he said
Nature of Experiments
Topographic conditions in this part
of the country are, however so
dis-s similar to the territory covered
in Quebec that the success of aerial
mapping here can only be determined
through experiments, he said. The
experiments will be undertaken in
the Ketchikan district and will prob
ably start within two weeks The
plane will cover territory not easily
accessible to the coast, searching
for lakes back in the mountains from
which power might be obtained and
photographs taken of heavily wooded
areas difficult of land reconnais
sance. Mr.. Jones, who owns and
operates the plane, is said to be an
experienced flyer and an expert
aerial photographer He recently
flew his hydroplane from Seattle to
Ketchikan.
bort Covers Power Sites
Mr.. bort, who will accompany hvia
tor Jones on his flights is this
season cruising Southeastern Alaska
investigating reported power site To-
cations which are not mapped and
looking for additional sites. He has
already reported two new sites which
are not shown on any maps. Last
year he covered all of the known
sites and compiled estimates on the
cost of development per available
horsepower and probable cost of total
development
Bio Tract Is Crulsed
Mr. Heintzelman returned Saturday
on the Alameda from Ketchikan.
During his absence from local head
quarters he visited the Bradfield
Canal district, where a party is
cruising a timber unit adjacent to
the Guggenheim's projected power
developments. This crew probably
finished its work yesterday, having
covered approximately $4,000 acres of
fine timber land. 1t will move at
once to Prince of Wales Island and
later come North to Thomas Bay.
New Development Planned
The power site at Thomas Bay
and Cascade Creek is now under
preliminary permit issued to Frank
F. Dougherty, OF San Francisco, and
Hutton & MoNair, New York brokers.
Mr.. Heintzelman had talk with Mr.
Dougherty at Ketchikan relative to
the latter's plans. The San Fran
cisco man had just completed trip
to Thomas Bay with two engineers
and was very well satisfied with the
outlook for economic power develop
ment and with the timber stands ad
jacent to the site He frankly ad-
ritted. that he had not definitely
capitalized his project but said he
hoped to put through a deal where
by the construction OF a large paper
mill, possibly between $50 and 800
tons capacity Mr.. Dougherty also
said he would return in September
or October with Eastern capitalists
who were considered as prospective
investors.
