nywhere. We will nowhave the lights turned off and give the picture man a chance.Our first picture shows a gang of laljorers shovelling dirtfrom a string of gondolas. You will note there are some ninemen on each car. The next picture shows hopper cars being unloaded tomake a slag fill for a railroad grade raising, and yard extensionimprovement. Slag does not run readily out of hoppers, andin addition to hauling it from beneath the car, men climbaround the sides and poke the material down through thehopper openings. We next show a regularly appointed waste material dump.The cars have, Men to the front of themjMen to the side of themMen on the top of themLong suffering waste cars. This view shows a special type of car built for handlingore from the mines on the iron ranges to vessels at ports.There are several points of interest about this car which willbear mentioning. When the ore docks on the lakes were first built, the binsor pockets were made 12 feet long. The cars were made 24 194

Ore isfreqnently in a wet. sticky condition, and will not rnn easily.This presented another problem to the car builder, and wassolved by givinj^ the floor plates of the car a high slope angle.Coal cars seldom have greater than a 30 degree slope on theend floors whereas ore cars run up as high as 55 degTees. Thehopper opening was made horizontal too, and very large, andthe inside sheets of the car coming in contact with the oreare sloped so that the angle to the horizontal is constantlyincreasing. This tends to make the ore run faster as it ap-proaches the hopper opening, and get out of the way of therest of the load. The car is known as a self-cleaning car andby that is meant that all of the load will run out when thehopper doors are opened. No labor is needed to poke the oredown through the hopper.
