expedition Of the National Geographic
Society.
DR.. Thomas A. Jaggar. late resident
a. the slopes of kilauea, Hawaii, Is on
hA way to Unga Island. in the Alaskan
Archipelago after conferrlng with the
research committee of the National
Geographic Society and members OF the
United States Geological Survey.
The yolcanologist will establish base
In the heart of the great battery OF
craters. Along the far-fiung Alaska
peninsula AT least so volcanoes rise Ike
bliSterS out of the water, dividing the
Pacific Ocean from the frigid Bering
Sea.
Into this sparSely inhabited. roadleSS
region DIR. Jaggar will bring his strange
amphibian boat. which will enable him
to maneuver on land and water 10
navigate straits. sounds and rivers, 10
traverse beaches and other natural
roadWayS.
The expedition viii find itself near
Paylof Bay, which is overlooked by
Mount PaXlof, Mount NeSuvluS' OF the
Alaska -Aleutian chain. Southwest OF
Pavlof is Mount Dutton, 5000 feet high,
and named only last Summer by Dr.
Jaggar on a reconnaissance survey.
All around are peaks, craterS and
snowy sky lines. And what they hold
is today almost as much matter of
speculation as at the time when Secre-
tary Seward engineered his famous
acquisition Of the Alaska Territory.

but also one of the most enhancing
scenic wonderlands, where the multiple

self mainly with volcanoes in the Mount
Psvlof sector, 1t also will investigate
animal and vegetable life of the area
The party will observe habits and mode
OF life among the little known Aleuts
on the south shore and ESkimoS on
the north shore These, with a few
Scandinavian fishermen and trappers
and American cannery employees, make
up the population.
Fur-tearing animals may be found in
abundance. There are brown bears.
CARIBOU, ptarmiganS, wolverines. foxes
and large fiocks of geese. The walruS
garnbol on the north and the sea lions
on the south.
The long, Jagged coast line contains
many haroors, some OF which un-
doubtedly are deep and navigable for
ocean liners. II is estimated that along
600 miles of the Aleutian coast there
are as many as $50 natural harbors.
Yet no ship Of large tonnage would
dare venture along this unchaTted
coast. Hidden rocks that can rip the
tin1bers Of the stsnchest craft arc
known TO abound. Until suitable maps
are made most of this wonderland will
remain unvisited.
This Summer. Or. Jaggar and his
staff viii begin the work of exploration,
mapping the interior and the coasts.
RY their intensive study OF repre-
sentative Alaskan volcanoes the
investigators hope TO add much to the
store of knowledge. Results in Alaska
viii be correlated with those in Hawaii
an6 Japan. where active volcano are
under constant scrutiny Having DEM
cnStrated that science can predict
disastrous eTuptions. DR.. Jaggar believes
that further study will do much toward
pcrfecting the method.
The mysterious interior Of Mother
Earth is as active as ever. Within the
past few years some Of the most DAM
aging eruptions Of human history have
taken hundreds Of thousands Of lives.

ciated Eith volcanoes. II is through a

resemble those of the north coast Of
