ferriferous material is generally derived from extraneous though contiguous
sources through simple permutations and reactions.” ‘ :

Of the Vancouver Island deposits, he describes the Sarita River
occurrence (Logan location) with a section, and an occurrence at Sechart
with two sketches (either Crown Prince or Bald Eagle deposit). These
are both classified as replacements of limestone. Reference is also made
to the occurrence described by Dawson near Sooke harbour, and this is
described as belonging to the second group mentioned above.

In 1902, Webster (7) and Hayeock (8) made a geological reconnais-
sance of the west coast of Vancouver island from the vicinity of Victoria
northwesterly to and including Nootka sound. Their field mapping
was done on the Admiralty charts, but unfortunately no geological maps
accompany their reports. They state that the outline of the geology
given by Dawson for the north end of the island applied in general to
the coast line they examined: but Webster believes that the crystalline
limestones which Dawson includes with the Vancouver series belong
to an unconformably older formation. He also states that ‘the tracing
of the boundaries of these various limestone bands is of importance, as
almost invariably the deposits of iron and copper ores are found at or
near the contact of the limestones with the igneous or voleanic rocks.’”!
Both writers give brief descriptions of the Newton magnetite deposit on
Gordon river and of the magnetite deposit on Copper island, Barkley
sound; and Haycock mentions the occurrence of magnetite on Sooke
peninsula.

The first systematic investigation of the iron deposits of the west
coast of Vancouver island was undertaken in 1902 by Carmichael (4) for
the Department of Mines, British Columbia. In his report Carmichael
outlines briefly the economic and industrial aspects of the iron and steel
situation of the Pacific Northwest, summarizes the geology of the west
coast as laid down by Dawson, and gives detailed descriptions, in some
vases accompanied by sketches and plates, of the deposits on Nootka
sound, Hesquiat lake, Sechart peninsula, Henderson (Anderson) lake,
Alberni canal, Sarita river, Copper island, Bugaboo creek, Gordon river,
and Sooke peninsula. <A table is also submitted giving complete analyses
of samples from most of the deposits described.

The magnetite deposits of Vancouver island were again the subject
of detailed investigation in 1907 when Lindeman (16) examined the prin-
cipal locations for the Dominion Department of Mines. His report con-
tains descriptions of most of the deposits examined by Carmichael, accomp-
anied by a few analyses, as well as statements of the amount of develop-
ment work done upon each one. It provides, also, a magnetometrie map
of the Iron Chief or Western Steel claim on Sechart peninsula; and the
first authentic description of the limonite deposits of Quatsino sound.

During the summers of 1908, 1909, and 1910 Clapp (17) was engaged
in making the first systematic geological reconnaissance of the southern
part of Vancouver island for the Geological Survey. The country examined
included the east coast, southeast of Nanaimo, the west coast, southeast
of Barkley sound, and all the accessible parts of the island southeast of a
line joining these two districts. In addition to the areal and stratigraphical
geology, Clapp paid some attention to the mineral deposits, amongst which
he mentions the magnetite deposits of Gordon river, Bugaboo creek, and
