But all these earlier steamers had large wheels on theirsides, and ^vere not suited for ocean voyages. In 1836, John Ericsson, a Swede, invented the propeller,which is placed at the end of a ship, and is nearly alwaysunder water. This brought it into use, and made ocean travelrapid and safe.

More mills w^ere built and our cotton cloth w^assoon sold everyw^here. The Erie canal reduced the cost of was very difficult to separate the seed from the fiber, and thisadded greatly to the cost of producing it. In 1793, Eli Whitney, an ingenious young man from Massa-chusetts, who was then teaching in Georgia, undertook to makea machine to do this work. He inventedtlie cotton gin, which could clean as muchcotton in a day as five hundred negroes. This made cotton-raising more profit-able, and it soon became the chief productof the Southern States. It also greatlyreduced the price of cotton cloth, and thusJohn Ericsson. increased the demand for it. To supply this demand, mills were built, Avater power and, later, steamwere used to run the looms, and our cotton cloth was soonknown and sold in every part of the world.
