more or less continuit3M)f the ore development, or at least oc- 
casional replacements of disrupted masses of limestone on the 
flank of the syenite summit for a few hundred feet from the 
old working.* Search in this direction was not resumed. But 
the admixture of pyrite in the ore exposed in that working is 
in deleterious proportion. Heavy float overspreads the sur- 
face below the ore bluff, and outcrops of ore, apparently in 
place, on the same slope below, point to a probable occurrence 
of other ore bodies at lower elevations on the same strike. A 
similar tendency to recurrence of ore developments at differ- 
ent elevations on terminal edges of disrupted limestone belts 
on Redonda island, and on Broughton peak, Barclay sound, 
was likewise suspected. In neither instance however have ex- 
cavations been made to uncover concealed ore lenses, if such 
they be, on the strike of the terminal ore bodies exposed at 
these several localities, all discoveries of the kind having been 
in natural exposures on the face of cliffs, bared by erosion 
and at considerable elevations. Ore bodies, like the three on 
Texada first described, whose longer axes are with the crest of 
elevations on the sides of which they are lapped, are, on the 
contrary, all developed toward the base of moderate elevations 
an apparant rule to which the ore body of the same type on the 
Serita, Barclay sound, proves no exception. In such circum- 
stances there is of course no scope for recurrence of ore in a 
given cross section except under cover of a low talus or mantle 
of drift, as on Texada, below the level of the swamp. That 
any development of ore occurs below water level — there seems 
no reason to conclude. 
Besides the occurrences above noticed, other small indica- 
tions of magnetite along the extension of the limestone belt 
have been observed b}' previous visitors,! notably one occur- 
rence on the northeast side of the island. At tlie point re- 
ferred to, crystalline limestone, according to Dr. G. M. Daw- 
son, occurs in association with hard greenish altered volcanic 
rock of the usual character. 
"It is in some places quite free from magnetite, but is generally high- 
ly charged with that material, which, though forming in it iu very ir- 
regular masses of hard ore, has generally more or less of a stratiform
