Most of the companies prospecting on Graham island have
furnished assistance, among them the Graham Island Collieries
Company, the Graham Island Coal and Timber Syndicate, the
B.C. Oilfields, Limited, and the Western Coal and Iron Cor-
poration, Limited. Mr. Milnor Roberts, in charge of the
development work for the latter company, and his assistants
Mr. Livingston Wernecke and Mr. J. M. MacDonald have been
particularly helpful, both in active co-operation in field work,
and by furnishing analyses and other data. Mr. J. H. Dawson,
Surveyor General of British Columbia, also, has given valuable
assistance by furnishing maps.

In the preparation of this report, the writer has frequently
received advice from the members of the Geological Department
of the Massachusetts Institute of Technology, Professors
Lindgren, Warren, Shimer, and Lahee. In no way, however,
are they to be held responsible for any of the statements
made.

AREA.

Graham island is the largest of the Queen Charlotte group,
and with the exception of Langara or North island, it is the most
northerly. Its total area is about 2,500 square miles.

The south-central part of the island, comprising the district
between Skidegate and Masset inlets, and containing about
300 square miles, was mapped on a scale of 1 inch to 1 mile.
The map on a reduced scale of 1 inch to 2 miles accompanies
this report. The portions of this area underlain by coal bearing
rocks were carefully examined and, outside of the coal basins,
sufficient work was done to determine the structure of the under-
lying rocks and the absence of coal measures with as much
certainty as the outcrops would permit.

Reconnaissance traverses were made through Skidegate
channel, and up the west coast nearly to Kano inlet; up the
east coast to Lawn hill, and thence westerly across the north-
eastern lowland to the valley of the Yakoun river. Hidden
creek, Ghost river, King creek, and other creeks west of the
