Image: Casting a marine engine cylinder at the Etna Iron Works, 1866
Description: Casting the giant marine engine cylinder for either the steamboat Bristol or her sister ship Providence (probably Bristol) at the Etna Iron Works of New York on February 3, 1866. These 110-inch cylinders were the largest-bore marine engine cylinders ever cast in the United States at the time. The illustrator appears to have understated the diameter of the cylinder bore as it only looks to approximate the height of the men surrounding it (5 to 6 feet) when in fact the bore was more than 9 feet in diameter.
