The most massive ore-handling machinery in the world is in use at this great lower lake port. Here come untold millions of tons of ore to be transhipped to Pittsburgh, Youngstown, and other blast furnace points. The big Hulett unloader dumps its burden into a bin almost as soon as it is out of the hatchway. While it is diving down into the hold for another load, the bin, which is mounted on wheels, moves away and dumps its contents into waiting cars, as seen in the picture. By the time another mouthful is ready the bin is back to receive it. The cars are standing under the rear end of the unloader.
