[7] 247 Literary and Scientific In a recent lecture Prof. Beal, of the Michigan Agricultural College, mentioned some trees which have been of great value. A walnut tree at Potterville sold for $1,000, the wood being highly ornamental, in beautiful waves, and it was made into veneering. A black walnut at Brookfield, seven feet through, sold at $1,200 for the same purpose, in New York. Two thousand dollars were refused for a large blistered walnut at Saugatuck. At Grand Rapids a black cherry tree, with very dark wood, was shipped to Central America, and from there shipped back to this country and sold as good mahogany.
