It is remarkable how long it takes for a good idea to travel from one country to another. The black walnut was introduced into England from America in 1656, but the fact that it is a far superior tree for timber to the old English walnut, has only recently been recognized. It is not only said to be a better timber, but to grow in ten years as much as the other will in twenty. Large quantities of the walnut logs are sent to Liverpool almost weekly by the American Line of Steamers from Philadelphia, and this fact has probably induced lumber men to take note of how well the tree itself grows there.
