In 1862, Mark's father died, and the young man took charge of the business for the estate. When he closed up the store successfully, five years later, he knew all about the grocery business, and his energy was proverbial in the city of Cleveland. At the age of twenty-seven he married, and went into business with his father-in-law, Daniel P. Rhodes. The firm Rhodes & Company traded in coal, iron ore, and pig iron. That was a generation ago. Young Hanna threw himself into that business with passionate enthusiasm. He learned the iron trade from the bottom, omitting none of the details. He was insatiably curious.

After he had reduced mining to an intelligent system—for he had a genius for organization and administration—he added shipping the products; and he reduced that, too, to a system and turned to ship-building.

In the early eighties he bought the Cleveland opera house, and a little afterward entered the banking business, to the management of each of which he applied the same methods of industry, thoroughness and attention to mi-
