The J. M. White,, if not previously mentioned in mudcat, was launched in 1878, and was on the Greenville, Vicksburg, New Orleans run.
A powerful boat, capable of beating any other, it proved expensive to run and pushed the owner, Capt. John W. Tobin, towards bankruptcy. It burned at the Blue Store landing in 1888, with the loss of 28 lives.
