Br. C. C. Martin reports coal of good quality as occurring 
in Alaska from twelve to twenty-five miles inland from Con- 
troller bay, in the valley of Bering river. The coal occurs in 
several seams, one of which is reported to be twenty feet in 
thickness. Much of the coal is a hard bituminous variety ap- 
proaching anthracite, and in one locality, at least, is a seam o^ 
natural cok" Details concerning this district are given in Bul- 
letin 225.

IX A PAPER READ BEFORE THE NeW YoRK AcADEMY OF 
ScrENCES, Dr. Charles P. Berkey, of Columbia University, 
discussed "A Geological Reconnaissance of the Uintah Reser- 
vation, southeastern Utah.'' He said in part: "Observations 
made in connection with other lines of work last summer have 
shown an erosion unconformity in the Carboniferous strata of 
the western Uintahs. It is marked on the south side of the 
range by an unevenness in the floor and a development of con- 
glomerate the pebbles of which are of the preceding formation. 
The break comes just above the chief limestone member of the 
series. 
"The junction between the great basal quartzyte of the 
United States and the overlying strata is marked by a fault in 
this region with sufficient throw to bring two quartzyte beds 
together on the higher plateaus and be easily overlooked. This 
makes it impossible to confirm Powell's unconformity at the 
top of the quartzyte as described by him in the eastern Uintahs. 
"The discovery, however, of the Carboniferous erosion in- 
terval a "little higher in the series throws additional doubt upon 
the assumed Carboniferous age of the great quartzyte member. 
Allowing the break to cut out a part of the 'Wasatch' limestone 
and the 'Weber' quartzyte, as developed in the Wasatch up- 
lift, the lithologic succession is satisfied better bv assuming 
Cambrian age for the lowest member in the Uintahs. 
"There is no other break to the close of the Cretaceous. 
A progressive unconformity, which increases in value against 
the flanks of the range marks the development of Tertiary 
sediments in the Duchesne valley. A conglomerate formed 
in progressive overlap from the" stream vallevs to the higher 
mountain tops of the flanks, has peculiar characters near" the 
limestone belt, on account of which King called it 'Wyoming' 
conglomerate. These characters are too local to give it th^ 
assumed stratigraphic importance, while the flanking conglom- 
erates arc really of great rano-e."
