143 the syncline and, apparently, deeper water conditions prevailed. It is scarcely possible to draw safe conclusions; but the prob- ability that coal was not deposited in the southeastern part of the syncline and that the Honna valley and Maude and Lina islands may be barren of coal seams cannot be ignored. This hypothesis should not be accepted as fact, however, and the careful prospecting of the small eastern tributaries of the Honna river is recommended. YAKOUN BASIN. Camp Wilson. Location. Camp Wilson is located on Wilson creek, in the N. W. 4, sec. 25, tp. 7. It is distant over 11 miles from Camp Robertson and about 20 miles from Queen Charlotte by the trail. A trail about three-fourths of a mile long leads from Camp Wilson to the Yakoun river, which is navigable for river boats at most stages of water from where the trail meets it to its mouth at Masset inlet 32 miles distant. Stratigraphic Position. The strata in which the coal seam at Camp Wilson is found belong to the Haida formation and the seam has been found by boring to be about 400 feet above the base of the formation. The rocks in this portion of the Yakoun basin are on the whole coarser than those in the Honna basin; and are composed of more angular, less sorted debris of the Yakoun volcanics. Coal Openings. The coal openings at Camp Wilson are three in number. No. 1 opening, on the right bank of Wilson creek, consists of an adit on the seam for a distance of 50 feet from the portal. At 8 feet from the entrance a winze 11 feet 6 inches deep gives access to a drift on the seam. From the winze this drift extends 20 feet south, and 24 feet north. Near the end of this northern portion a narrow crosscut exposes the full width of the seam. No. 2 opening is a shaft 14 feet deep from which a drift runs south on the seam for 20 feet.
