sea cliff and boated off to the ships through the surf. There 
is no harbor for vessels nor protection from any but south 
winds. In 1903 a small amount of coal, probably not exceed- 
ing 20 or 30 tons, was produced at the Cor win mine. In 1904 
about 20 tons were taken by the steamship Corw'm and about 
10 niore tons were mined for consumption at the Point Hope 
whaling station. 
The Paleozoic coals outcrop at three points along the coast, 
4, 8 and 12 miles, respectively, south of cape Lisburne. The 
coal-bearing formation extends southward for a distance of 
about 40 miles, and reaches the coast again at cape Thompson. 
Beds over four feet in thickness occur at each of the localities 
noted. No analysis of these coals has yet been made. They 
are bituminous and of considerably better grade than the 
Mesozoic coals of the region. They are totally undeveloped, 
but in 1903 a few tons were mined from croppings in the sea 
cliffs and used at the Point Hope whaling station. 
The American Institute of Mining Engineers is plan- 
ning for an excursion to British Columbia and Alaska as its 
summer meeting. The excursion party is expected to leave 
Chicago June 24th, by special train, running direct to Victoria. 
After the sessions at Victoria, an excursion of about 21 days 
will be made by chartered steamer and special train to Snet- 
tisham bay, the Treadwell mines on Douglas island, Juneau, 
Shakan, Skagway, White Horse, Lake Labarge, Dawson (at 
the mouth of the Klondike), the neighboring mining camps, 
and back to Victoria. On the way east from Victoria, five 
days will be spent in visiting mining districts in British Colum- 
bia (including, probably. Nelson, Rossland, Trail, Greenwood, 
etc.) ; and the party will reach Chicago about August 3d.
