Mr. C. B. Paddock, Albany, 111., writes: "On the northern limit of the Pecan, it may be of interest to note I have frequently seen the matter mentioned and have never noticed that any one had seen it further north than between St. Louis and Quincy. Last fall I was shown a few nuts by a person on whose word I should rely, who declared they were gathered on what is locally known as the Wapsie river bottoms, properly, I suppose, the Wapsiepin-nacon river. This river comes into the Mississippi river a few miles below here, say twenty or twenty-five miles above Davenport, and the locality where these trees are found is some twelve or fifteen miles west or southwest of Camanche, Iowa. Two or three other persons have since assured me that Pecans grow in the district described".
