The mounted carriers' mail route in the third, second and first wards has been laid out and will be carried for the first time tomorrow. Wüliam Baxter, carrier No. i., has been transferred to the mounted service and will take the new route. He will be armed with a whistle, which will notify those getting mail that the carrier has passed. The citizens on the new route have promised to put out boxes, which is the only way in which the new carrier can carry the extensive route. He starts in at the corner of Main and Summit streets and goes to the Gott addition, making the side streets; thence through Seventh street to Madison, taking in West Liberty, West Washington, down Madison and Mosely streets to South Main, thence to the city liraits. He trien carries Hill, Brown, Lincoln, etc, and the Lawrence addition. In a few days, it is expected to get the other horse carrier in active operation. George Blum, carrier No. 2, will carry the district given up by carrier No. 1, and Charles Meyer, who has been promoted from substitute carrier to a full carrier will take district No. 2.
