as the Paxton and Lake lenses on Texada. It rises to a hight 
of 75 feet above tide, its base near water level being concealed. 
(Plate III, Fig. 3). Longitudinally its outline in section is 
that of a crescent. At the east end of the bluff-like elevation 
it is exposed in cross section, and its structure full}^ revealed 
as a replacement of marble of which the axial portion remains- 
unaltered. On both sides of this midrib of unaltered marble 
ore is developed to a maximum thickness of about 30 feet, 
with reverse dips of 84° to 85°, resulting in an anticlinal config- 
uration. The length of the ore-body may be taken as about 
200 feet. Prismatic blocks of magnetite were found developed 
around angular masses or cores of marble. These are here 
represented by photogravures. No other discoveries have 
been made along the extension of the same marble belt. The 
environment of this belt is eruptive rock of the usual dioritic 
type, more or less epidotic according to degree of secondary 
alteration. 
Sooke Harbor. On the second headland facing the Strait 
of Fuca south of Sooke harbor, a differentiation of magnetite 
from weathering action on exposed surfaces of a basaltic dio- 
rite has led to the enumeration of this locality among the 
known occurrences of iron ore on the island of Vancouver.* 
A number of shallow excavations, while affording some mate- 
rial of excellent quality, sutfice to show the superficial char- 
acter of this development upon glacial surfaces of a consid- 
erable area bordering the precipitous shore of the strait. A 
correct notion of the character and limitations of this occur- 
rence may be formed from its description as an incipient and
