We have on hand here 25 new flat cars; at Cairo 9 more; at Michigan City, completed or nearly so, 20 more; in all, 54 cars, all of 5-foot gauge. We have sent the last week to Jeffersonville, for General Rosecrans, 25 box and 18 flat cars, also early in the month 19 box and 12 flat cars, making already sent to Jeffersonville, opposite Louisville, during the month, in all, 74 cars, and making, with what we now have ready, or nearly so, 128 cars. We can send a part of the 25 cars this week, the balance in the early part of next week. We can have from 2 to 4 cars per day changed to 5-foot gauge, but the Pacific Railroad will have to furnish them, and they are already getting short, having just furnished us some for General Steele in Arkansas. Telegraph more definitely to-morrow. No effort will be wanting to forward the cars with the least possible delay from all points.
