Lumber and Grain, Coal and Ore
Beginning in the 1840s, the Great Lakes became busy highways for moving wheat, corn, lumber, coal, and iron ore. Crops from midwestern farms crossed the lakes to markets in the East. Lumber from the region’s vast pine forests made Chicago the world’s busiest lumber port in the 1870s. Iron ore from the region traveled east on ships that returned filled with coal from Pennsylvania. To this day, iron ore makes up nearly half the cargo on the lakes.

Freighters in the Soo Locks, Sault Ste. Marie, Michigan, about 1900
Canals helped the Great Lakes prosper. The state of Michigan built the St. Mary's Falls Ship Canal, called the Soo Locks, from 1853 to 1855 to speed ore and grain from Lake Superior to markets and industries along the lower lakes.

Farms on the American prairies produced the grain that was shipped east through the Great Lakes or down the Mississippi River. Threshing time—when the grain was removed from the stalks—required many hands to help process the grain for shipment.

Logging thrived around the Great Lakes from the 1850s through the 1880s, cutting whole forests from the landscape. Even past logging’s peak, demand for lumber kept loggers and shippers in business. The sled of logs displayed here—surrounded by stumps—yielded 13,562 board feet of lumber.

Iron miners at the Jackson Mine, Michigan, about 1870s
Mines in Michigan’s Marquette Range, such as the Jackson Mine, supplied all the iron ore shipped on the Great Lakes until 1877. Workers mined iron by hand until 1884, when steam shovels were adopted.

The first trestle ore dock was built at Marquette, Michigan, in 1859. The design took advantage of gravity to unload railroad cars and fill the holds of waiting ships.

Scow Schooner Milton
The Milton spent 20 years hauling lumber on Lake Michigan, along with hundreds of other small boats nicknamed the “mosquito fleet.” Built to carry as much cargo as possible, many of these boats did not sail well. The Milton collided with another ship and twice ran aground. In 1885, five men died—three of them brothers—when the Milton sank during an autumn storm.
Bulk Cargo Carrier
Schooners like this dominated the movement of grain and lumber on the Lakes from the 1820s into the 1890s. The Ed McWilliams was designed with a shallow hull to enter small harbors. The crew bunked under the forecastle at the front of the ship, but they ate in the deckhouse at the stern, surrounded by the master, mate, and cook’s cabins. The schooner’s long middle held the cargo.
Wind and Steam
Early steam engines freed ships from unpredictable winds, but they were inefficient and costly to run. Many Lakes boats relied on both sail and steam. The Edward Smith could sail its cargoes of lumber, ore, or coal on the open lakes and still use its engine to maneuver in confined channels. In 1926, the ship sank in a storm on Lake Superior, with no loss of life.
To make vessels more stable, steamer captain Alexander McDougall patented a rounded hull that would be almost submerged when loaded. He called his boats “whalebacks,” but others nicknamed them “pigs.” Many ended their working lives as barges. The Frank Rockefeller carried iron ore, sand, grain, petroleum, and even automobiles for 73 years.

In 1899, ships on the Great Lakes carried 12.5 million tons of ore, and 12.1 millions tons of coal. Even though dockyards began using unloading hoists like these, workers still shoveled most ore, coal, stone, and grain out of ships’ holds by hand.
The James Barker
Three thousand boats worked the Great Lakes in 1893. By 2000, the number was less than 200, but the huge vessels in use today carry more cargo. The James R. Barker is one of the largest ships working the Lakes today. In one trip, the Barker can carry more than 60,000 tons of ore, enough to produce the steel for 16,000 automobiles.
