haustive analyses of all iron ores
shipped from the Lake Superior
district in 1921, or available for
shipping in 1922 says Skilling's

Iron Ore BY Ranges.
OF the Guyana grades the Croft
Bessemer (the only Bessemer ore
quoted on the range) contains the
highest dried iron, COLL, highest
natural iron, 53.97, and lowest
phos., .039, on the range. The
highest manganese ore is the Again.
ing 1859, the lowest silica is the
Sycamore Lump, the lowest moist
ure the Maroco No. 2 washed, the
highest moisture, the Portsmouth
and Whitmarsh, 1900.
The Cahoon ore is quoted from
the Baraboo range, it being a non
Bessemer ore with a 1892 natural
iron. The Mayville ore from the
Mayville range shows natural
iron of 40.79, and a phos. of
1920.
On the Gogebic range the Yale
ore shows the highest dried iron
1888, the lowest phos., .O35, and
lowest silica, $50. The Ashland
ore has the highest natural iron,
57.61, also the lowest moisture.
The Plymouth Rex shows the high
est moisture.
Of the Marquette range ores
the Republic Basic and Bessemer
Lump shows the highest dried iron,
64.0O, the lowest moisture rs. The
Basic Lump is the highest natural
iron, the Holmes Bessemer the low
est phos., the Cliffs Shaft Lump

ore the highest moisture.
On the Menominee range the
highest dried iron is the Brier Hill,

shire, .681. The highest moisture
quoted is the Ernst, 10.39Ro.
On the Mesabi range the Mesabi

Summary of Iron Ranges.
MANY OF the grades quoted are
special ores, representing very small
tonnages. In some instances a com
paratively small product from a
property is divided into 4 or 5
