Shipping Three Cars Daily.
At the Superior & Boston the relief
from car shortage that came during
the last days of May resulted in steady
shipping at the rate of three so ton

Iron Cap Production.
The Iron Cap management predicts
a June output Of 500 tons Of high grade
ore. Its prediction Of 800 tons for
May was exceeded by the actual ship
ment- The $50 foot level is now AL
feet from the mouth Of the drift and
the rich ore body is still holding up
in size and value. The company has
not yet crOsscut, sunk or raised on the
ore, following It with drift two
sets wide, exposing an average of II
feet wide. A raise has been started
20 feet back from the face Of the drift
to ascertain the height of the ore body.
CrOsscuts and wines also viii be driven
to explore the body. The ore holds
an average of u percent copper and
the streak Of high grade in the center,
varying from u to "A inches, runs as
high as so percent copper, and over
100 ounces in silver The Iron caps
May shipments were greatly retarded
by car shortage, but the railroad seems
