Engineer Bureau, March 28, 1864
  Special authority was obtained more than a month since to construct the bridge over the Tombigbee River, near Demopolis, and Maj. Minor Meriwether placed in charge. Major M.'s reputation for skill and efficiency induces me to believe that everything will be done that can be to secure the prompt completion of the bridge.
  Owing to the size of the river and the character of the freshets, however, the undertaking is one of such magnitude that in the present limited mechanical resources of the Confederacy it can scarcely be accomplished before midsummer.
