The Pioneer of Assumption says, that among the seventy-nine specimens of native woods already procured by the committee chosen for the purpose, and now in the possession of custodian E. P. Helluin, to be sent to the World's Exposition, is that of a cypress tree measuring 8 feet 2 inches in diameter. This mammoth tree was felled and hewed by Mr. John Christian, on Four-mile Bayou, some fourteen miles in the interior, which operation consumed seven days, as much as three or four men being employed at the same time. The tree, however, is what is known among lumbermen as "wind-shake" split, but otherwise sound as a nut; so much so, indeed, that a dug-out is being made out of a part of it.
