The city has a considerable trade in grain, lumber, fish, livestock, dairy products and oil; its manufactures include boilers, machinery and canned and pickled fish, especially salmon and herring.
East Chicago is industrially virtually a part of "Greater" Chicago; among its manufactures are iron and steel, cement, lumber, boilers, hay presses, chains, chemicals and foundry products.
There were four boilers made of thin hammered copper and weighing a little more than 7 lb each; these occupied the middle portion of the fish.
Other important industries include the making of boilers, steam-engines, locomotives, anchors, chain-cables, sailcloth, ropes, paper, woollen and worsted goods, besides general engineering, an aluminium factory, a flax-spinning mill, distilleries and an oil-refinery.
Locomotives, boilers and machinery of all kinds are made in other great establishments.
