76 ALASKAN MINERAL RESOURCES IN 1906. 
both soundness and quality of the marble greatly improve, and flaw 
less blocks of large size may be quarried. The dimensions of these 
blocks, however, are dependent on the handling capacity of the; 
machinery. Small shipments of this product have been made to 
many of the large cities as far east as Ohio, though the greater por- 
tion is sent to Tacoma, where a cutting and polishing plant has been 
built. Last year the capacity of the mining plant was materially 
increased with a view to an enlarged production in 1907. 
On the opposite side of the low mountain range a similar marble 
deposit is exposed, and has been partially developed by the El Capi 
tan Marble Company. This property is located on the north side of: 
Klawak Passage, 6 miles from Shakan village. The marble exposed 
in the quarry close to tide water is comparable with that at Marble 
Creek above described, except in solidity. Thin fragments of the 
marble crumble more readily in the hand, and the position of the; 1 
present workings is less favorable for extensive quarrying. A thou- 
sand feet back from tide water surface cuts and stoppings have 
exposed a much firmer and better marble at the foot of a steep bluff. 
This company began operations in 1904, installed channeling and i 
gadding machines, erected a marble-sawing plant, and made a small I 
shipment. During the last two years no further quarrying has been i 
done and only small developments have been made. 
A number of marble claims were located in 1902 about 30 miles to 
the south of Shakan, on the northwest side of Marble Island, in David- 
son Inlet, but practically no work was done on them and they were 
relocated in 1906. Several varieties of marble of good quality are 
exposed and the deposits appear worthy of further investigation. 
At Baldwin, near the head of North Arm, an inlet on the east side 
of Prince of Wales Island, beds of marble have been located and devel- 
oped by the American Coral Company. The deposit at this point con- 
sists of marble beds interstratified with chloritic schists striking N. 
65° W., with a nearly vertical dip. The marble varies greatly in color J 
and composition, and although some of it is of excellent quality it! J 
would probably be difficult to obtain any large quantity of a uniform 
grade. Most of the product contains a small percentage of silica andij 
some alumina and magnesia. Pyrite in disseminated particles was 
also observed in some of the marble. The surface exposures were 
badly fractured in places, but this condition is probably confined to a 
depth of 10 to 20 feet from the surface. In 1905 a wharf was built, 
machinery installed, and buildings erected. In 1906, however, prac- 
tically no work was done. 
At the north entrance to Johnson Inlet, about 3 miles east of Dolomi 
a second group of claims has been located by this company on a simi- 
lar marble belt. Work at this point has been meager and but litth 
was accomplished during 1906.
