The wood of this catalpa has been thoroughly tried out for a number of purposes. Furniture and finish have been made of it with varying success, and molding and picture frames are listed among its uses. It is not a sawlog tree. Statistics of lumber cut seldom mention it, though now and then a log finds its way to a mill. Efforts have been made to pass the wood as mahogany, but with poor success. The counterfeit is easily detected, since the artificial color which may be imparted to catalpa is about the only resemblance to mahogany. In the lower Mississippi valley some success, but on a very small scale, has resulted from attempts to induce catalpa to grow in crooks suitable for small boat knees. The young trunk, after being hacked on one side, is bent and induced to grow the crook or knee. Natural crooks have been utilized in the manufacture of knees for small boats in Louisiana. Probably ninety per cent of all the catalpa ever cut has gone into fence posts. It is habitually crooked. A straight bole is the exception; though in plantations trees are crowded and pruned until they grow fairly straight, and sometimes trunks of forest grown trees of large size are nearly faultless in their symmetry. It was once believed in some quarters that catalpa would solve the railroad tie problem by growing good ties quickly. It must be admitted, however, that in spite of extensive plantings, the railroad tie problem has not yet been solved by catalpa. COMMON CATALPA (_Catalpa catalpa_) originated many hundred miles outside the range of hardy catalpa, to judge by the localities in which it was first found by white men. It is supposed to have been indigenous in southwestern Georgia, central Alabama, and Mississippi, and northwestern Florida. Its range has been greatly extended by planting, and it grows in most parts of the country east of the Rocky Mountains, as far north as New England. It has been planted in many parts of Europe. Its leaves, flowers, fruit, and the tree itself are smaller than hardy catalpa. The pods hang unopened all winter. The trunks sometimes are three feet in diameter and sixty high, but are generally small, crooked, rather angular, and poor in appearance, but the leaves and flowers are ornamental. The wood is durable in contact with the ground, and its largest use has been for posts, crossties, and poles.
