Minnesota -- Description and travel; Northwest, Canadian; Northwestern States; Red River of the North
The new city of the Northwest is sheltered from northerly winds by
the high lands behind it. The St. Louis River, a stream as large as
the Merrimac, after its turbulent course down the rocky rapids, with
a descent altogether of five hundred feet, flows peacefully past the
town into the Bay of Superior. The river and lake together have thrown
up the long and narrow strip of land called Minnesota Point, reaching
nearly across the head of the lake, and behind which lies the bay. It
is as if the Titans had thrown up a wide railway embankment, or had
tried their hand at filling up the lake. The bay is shallow, but the
men who projected the city of Duluth are in no wise daunted by that
fact. They have planned to make a harbor by building a mole out into
the lake fifteen hundred or two thousand feet. It is to extend from
the northern shore far enough to give good anchorage and protection to
vessels and steamers.
The work to be done is in many respects similar to what has been
accomplished at both ends of the Suez Canal. When M. Lesseps set about
the construction of that magnificent enterprise, he found no harbor on
the Mediterranean side, but only a low sandy shore, against which the
waves, driven by the prevailing western winds, were always breaking.
The shore was a narrow strip of sand, behind which lay a shallow lagoon
called Lake Menzaleh. There was no granite or solid material of any
description at hand for the construction of a breakwater. Undaunted
by the difficulties, he commenced the manufacture of blocks of stone
on the beach, mixing hydraulic lime brought from France with the sand
of the shore, and moistening it with salt water. He erected powerful
hydraulic presses and worked them by steam. After the blocks, which
weighed twenty tons each, had dried three months, they were taken out
on barges and tumbled into the ocean in the line of the moles, one of
which was 8,178 feet, nearly a mile and a half, in length; the other
5,000 feet, enclosing an area of about five hundred acres. More than
100,000 blocks of manufactured stone were required to complete these
two walls. They were not laid in cement, for it has been found that a
rubble wall is better than finished masonry to resist the action of the
waves. Having completed the walls, dredges were set to work, and the
area has been deepened enough to enable the largest vessels navigating
the Mediterranean to find safe anchorage.
These breakwaters were required for the outer harbor, but an inner
basin was needed. To obtain it, M. Lesseps cut a channel through the
low ridge of sand to Lake Menzaleh, where the water upon an average was
four feet deep. A large area has been dredged in the lake, and docks
constructed, and now the commerce of the world between the Orient and
the Occident passes through the basin of Port Said.
