STEVENSON— INTERRELATIONS OF THE FOSSIL FUELS. 169 



republished in his report upon a reexamination of the region in 1895. 

 His studies were confined to the southern coast and the adjacent 

 islands. Coal was discovered long ago on Admiralty Island, which 

 is east from Baronoff Island, on which Sitka is situated. The first 

 opening was made on Mitchell Bay and the coal was tested on the 

 U.S.S. Saginaw, but the resin was so abundant as to render it 

 unfit for use. The beds are very thin but, owing to the urgent 

 need for fuel, they were studied carefully. The especial features 

 are the woody structure and the abundance of resin. Kachemak Bay, 

 near the mouth of Cook's Inlet, on the Kenai Peninsula, is 1,200 

 miles west from Admiralty Island. Furnhjelm, long ago, saw there 

 a bed of coal, 9 to 1 1 feet thick, underlying clays, pebble rock and 

 sands, and resting on partly bituminous laminated clay shale. It 

 was black, brilliant and contained grains of amber. From the asso- 

 ciated rocks he obtained Unio, Aninicola, Melania and elytra of a 

 beetle, along with 44 species of plants, both conifers and dicotyle- 

 dons. The bed was no longer exposed when Dall visited the locality, 

 but, at Coal Point, he saw a bed 7 feet thick. In 1895, this bed had 

 been opened ' at the Bradley mine, where it showed leaf-bearing 

 partings and the best coal was at the bottom. Two other beds were 

 examined on this bay, 4 feet 7 inches and 6 feet thick. These are 

 complex. The coal dififers in the several beds; that at the Bradley 

 mine is evidently a glance, not soiling the fingers and, on drying, 

 breaking into cubical fragments, whereas that from the Eastland 

 mine is fibrous, dull charcoal black. 



At Amalik Harbor, 150 miles farther west, some thin coal beds 

 were seen, as also at Chignak, nearly 300 miles beyond. Amber 

 has been obtained on the shore of Portage Bay southward from Chig- 

 nak and from several other places in that region, as well as from 

 several of the Aleutian Islands. Many thin 'beds of lignite were 

 seen on Unga Island. One of these is very complex ; the upper 

 portion has half a dozen benches of bright and dull coal, each 4 to 

 5 inches thick, with thicker partings of carbonaceous shale. The 

 bench is fairly clean and 18 inches thick. Analyses of coal from this 

 bed gave 



On the basis of pure coal, the volatile is 49.55 and 81.26 in the two
