Thus, contrary to the stories that have been so widely published, the Edisons, while not rich by any means, were in comfortable circumstances, with a well-stocked farm and large orchard to draw upon also for sustenance. Samuel Edison, on moving to Port Huron, became a dealer in grain and feed, and gave attention to that business for many years. But he was also active in the lumber industry in the Saginaw district and several other things. It was difficult for a man of such mercurial, restless temperament to stay constant to any one occupation; in fact, had he been less visionary he would have been more prosperous, but might not have had a son so gifted with insight and imagination. One instance of the optimistic vagaries which led him incessantly to spend time and money on projects that would not have appealed to a man less sanguine was the construction on his property of a wooden observation tower over a hundred feet high, the top of which was reached toilsomely by winding stairs, after the payment of twenty-five cents. It is true that the tower commanded a pretty view by land and water, but Colonel Sellers himself might have projected this enterprise as a possible source of steady income. At first few visitors panted up the long flights of steps to the breezy platform. During the first two months Edison's father took in three dollars, and felt extremely blue over the prospect, and to young Edison and his relatives were left the lonely pleasures of the lookout and the enjoyment of the telescope with which it was equipped. But one fine day there came an excursion from an inland town to see the lake. They picnicked in the grove, and six hundred of them went up the tower. After that the railroad company began to advertise these excursions, and the receipts each year paid for the observatory.
