358 RECENT DEVELOPMENTS WITH THE CALYX DRILL 
exactly at one of these points where the strata would probably 
be much distorted and broken. However, be that as it may, it 
will be adm itted that the following attempts on the part of the 
operators have proved eminently successful, not only in estab- 
lishing the fact that large bodies of ore exist; but in assisting 
to prove that the formation here is a true synclinal basin. 
The position for this hole was ch osen after some deliberation, 
and it proved to be a happy one. Ata point on F, Wheelock’s 
farm, about 2 miles to the west of the above workings, the 
three veins spoken of in the first part of the paper, were proved 
on the surface, and the drill was set up 40 feet to the south of 
the most southerly of the three (the “Shell Ore” vein). (See 
Plate V.) The crops of the other two were respectively 84 feet, 
and 124 feet northerly from the drill. The three veins were 
intersected at the depths shown, and by reference to the sectional 
view, it will be seen that they are widening and flattening as 
they descend. Boring commenced here on Jan. 3, 1901, and 
finished on April, the drill operating for 1560 hours:

On the completion of this very satisfactory boring, the drill 
was moved over on the south side of the valley, formed by the 
Torbrook or Black River, and boring was commenced well up 
on the South Mountain ridge. The drill was situated close to a 
vein of compact magnetite, whose surface measurements gave 
the writer the following results taken from north to south:
