Field and Forest for August, a very interesting scientific serial of the more popular type,published by Mr. C. R. Dodge, of Washington, has an article on the Catalpa, to prove that it is not an introduced tree. We have read the arguments carefully, but think it does not take in the point fully. There is no doubt it was here when the white man found the country, but there are many reasons for doubting it is an aborigine, in the sense that other trees are. The probabilities favor the idea that it and the Honey Locust are wanderers in the far away past from Asia. How they got here we have as yet no means of knowing.
