In 1831, he contracted with the Government officers to build the light-house on Water street. In 1836, he built a light-house at Sandusky. 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 eighty-three years of age, his health is good, his memory remarkably active, and all his faculties unimpaired. He has two sons and one daughter yet living, having lost two children. He has had nine grandchildren, and five great-grandchildren. Noble H. Merwin. In classifying the early commercial men of Cleveland, the name of Noble H. Merwin is justly entitled to stand among the first on the list. In fact he was the founder and father of her commerce, and a man not only noble in name, but noble in character.
