peculiarly adapted to all those afflicted with pulmonary com¬ 
plaints, and such a thing as consumption, produced by the cli¬ 
mate, is almost unknown. The Bay of Superior opened April 
1st, 1860. The propeller Burlington left Bayfield December 
8th, and went into Ontonagon the same day for winter quar¬ 
ters. This shows over eight months, or 250 days of naviga¬ 
tion in 1860. Lake Superior never freezes in the middle, and 
but for a short distance from the shores. 
The military road from Superior to St. Paul, and the road 
from Mille Lac and Crow Wing, Minnesota, is now in good 
order. The St. Croix <fe Lake Superior Railroad possesses a 
grant of land from Government of nearly 1,000,000 acres, which 
will complete it within a few years. The Lake Superior & 
Mississippi Railroad Company received a grant of swamp lands 
from Minnesota, amply sufficient for its completion. 
The exports of the port of Superior of lumber for 1860 were 
over 200,000 feet, and about the same quantity of shingles, 
and laths; about 600 barrels fish, potatoes, and furs, besides 
numerous cattle driven in from Minnesota, and shipped to the 
copper mines. 
The difference in distance between Superior to Europe, and 
Chicago to Europe is but trifling, each place being at the head 
of a great Lake. After passing the Straits of Mackinaw, the 
course of a Superior vessel and a Chicago vessel is identically 
the same. The trade of supplies for, and emigration to north¬ 
ern Wisconsin, British America, Minnesota, &c., will be dis¬ 
tributed from our docks. 
A copper mine has been opened on the Mineral Range near 
town. The shipments of copper and iron ore from Lake Su¬ 
perior are rapidly increasing. In 1860 the various mines 
shipped over 8,600 tons rough, equal to over 6,000 tons ingot 
Copper, valued at $420 per ton, or $2,500,000. The shipments 
of iron ore from Marquette exceeded 150,000 tons, valued at 
$588,239. This ore is from 60 to 75 per cent, pure, and for 
strength and tenacity is without a rival in the world. 
The importation into Lake Superior of merchandise, machin¬ 
ery, cattle, provisions, (fee., amounted to $5,298,000 ; and the
