Ore and TimberAs ore traffic increases, machines are developed to speed up the job. They use a row of overhead cranes to drop a row of buckets down every hatch, hauling up loose ore by cable until clear of the hatches. The buckets then travel sideways, on long overhead rails, to a position over the dump zone. Ore accumulates in huge piles, to be later scooped up into rail cars for the continuing journey to Pittsburgh. |

Huge Traffic Boost The Soo locks dwarf anything previously seen in America. The original lock is three times longer than those being used in the Erie Canal, but within 25 years a larger lock is added, which is half-again bigger. By 1890, there is yet another new lock in operation, this time eight times the size of the Erie Canal locks, and designed to handle four ships at once. Soon enough, however, ore boats grow to such a size that only one can fit through at a time. | |||||||||

Wood for Housing During the same period, loggers are hauling huge loads of virgin timber from central Michigan. This is mostly white pine, which is hauled in astonishing loads over snow and ice. As the areas close to rivers are logged out, timber companies build their own private railroads to reach further into the interior. Even more timber is cut on the western shore of Michigan, bound for Chicago and Milwaukee. After 40 years, Michigan is effectively logged out by 1900. | |||||||||
