In the following year he constructed seven hundred feet of the stone pier
on the east side of the Cuyahoga river mouth. The first thing done in the
latter work was the driving of spiles. Mr. Johnson became dissatisfied
with the old system of driving spiles by horse-power, and purchased a
steam engine for four hundred dollars. Making a large wooden wheel he
rigged it after the style of the present spile-drivers, and in the course
of two or three weeks, had the satisfaction of seeing the spiles driven
with greatly increased speed and effect by steam-power.

About 1839, he took his new spile-driver to Maumee Bay and drove about
nine hundred feet of spiling around Turtle Island, filling the enclosed
space with earth to the height of three feet, to protect the light-house.
In 1840, he built the Saginaw light-house, sixty-five feet high, with the
adjoining dwelling. In 1842-3, he built the light-house on the Western
Sister Island, at the west end of Lake Erie. In 1847, he completed his
light-house work by building the Portage River light-house.

Besides his light-house building, Mr. Johnson erected in 1842 his stone
residence on Water street, and in 1845, the Johnson House hotel on
Superior street. The stone for the former was brought from Kingston,
Canada West. In 1853, he built the Johnson Block, on Bank street, and in
1858, he put up the Marine Block at the mouth of the river. This completed
his active work.

Since 1858, Mr. Johnson's sole occupation has been the care of his
property and occasional speculations in real estate. By a long life of
activity and prudence, and by the steady rise in real estate, he is now
possessed of personal and landed property to the value of about six
hundred thousand dollars, having come to the city with no other capital
than his kit of tools, a strong arm, and an energetic purpose. Though
