This bar of clay is moved along by ma-chinery to a great wheel or cylinder havdng wirespokes. The distance between two adjacentwires is equal to the width of a brick. As the 120 HOW WE ARE SHELTERED wheel turns, the wires cut the bar of clay intobricks. The bricks are now carried by machinery toa machine where they are powerfully are then loaded on to small cars, and runinto a dryer.
