--We were yesterday shown a hat made of rye straw, which, in point of beautiful appearance and elegant finish, we have never seen excelled. It was made by J. R. Holleman, an invalid soldier from Isle of Wight county, Va., and intended for His Excellency Jefferson Davis. The number of knots tied in making the hat was 18,500, and we learn that the whole of it was done by the hand. The straw itself was as fine as an ordinary sized darning-needle.
