Storage capacity of the Public Grain Elevator is 2,622,000 bushels. This is about 25 per cent of the grain elevator storage capacity of the port, but the Public Elevator handles 60 per cent of the business--proving its efficiency. Its unloading capacity is 60,000 bushels a day from barges or ships, and 200,000 bushels from cars. Loading capacity into ships is 100,000 bushels an hour--to one or four vessels, simultaneously. Fireproof and equipped with a modern dust-collecting system, this facility is considered one of the best in the country. Other grain elevators at New Orleans are operated by: Southern Railway: capacity, 375,000 bushels; Illinois Central Railroad two elevators, capacity, 2,500,000 bushels; Trans-Mississippi Terminal Railroad Company: two elevators, capacity, 1,350,000 bushels. Wharves owned and controlled by the Dock Board measure 28,872 linear feet in length, with an area of 4,230,894 square feet. Twenty of these thirty-four wharves are covered with steel sheds. Wharves operated by the railroads on both sides of the river increase the port facilities as follows: Southern Railway: Two concrete and steel covered docks, one a two-story structure; one is 150 by 1,300 feet, with a floor space of 195,000 square feet; one is 150 by 1,680 feet on the lower floor, and 120 by 1,680 on the upper, with a combined area of 453,000 square feet floor space. Illinois Central Railroad: covered wharf, 130-150 by 4,739 feet. Morgan's Louisiana and Texas Railroad and Steamship Company: wharf space, 112,000 square feet; covered space, 117,200 square feet. Trans-Mississippi Terminal Railroad Company: Wharf No. 1, three berths, 281,904 square feet; No. 2, one berth, 94,350 square feet; No. 3, one berth, 100,725 square feet--most of it covered; oil wharf, 15,000 square feet. The New Orleans Army Supply Base has a two-story wharf 2,000 feet long by 140 feet wide. The lower floor of the wharf is leased by the Dock Board. Back of it are the three warehouses, each 140 by 600 feet, and six stories in height. Seven industrial plants have loading and unloading facilities on the river. The Dock Board does not lease or part with the control of these, and controls the following charges: harbor fees, dockage, sheddage, wharfage, etc. Open storage on river front contiguous to wharves totals 1,169,900 square feet. There is a great deal of potential open storage space away from the wharves and along railroad tracks, which could be reached by switches. For the storage of coffee, alcohol, sisal, sugar and general commodities, private warehouses offer a floor space of 2,000,000 square feet.
