Ox-powered quarry
transport on Cape Ann during the local granite industry's Middle Ages1 |
Boston thought of itself as The Cradle of Liberty. The
Battle of Bunker Hill had been one of the decisive moments in the War for
Independence. As the Revolutionary veterans' numbers dwindled and the young
nation flourished, patriotic visionaries sought a suitable commemoration. They invited
the Marquis de Lafayette, who was touring the United States on the 50th anniversary
of the War, to lay the cornerstone of the Bunker Hill Monument on June 17, 1825.
Daniel Webster delivered the oration.

The railway was conceived by a young engineer named Gridley
Bryant. He was able to construct the three-mile bed so accurately over varied
terrain that a single horse could pull the loads, to the wonder of a newspaper
reporting on the first delivery of granite to Bunker Hill in 1826:
This railroad, the first we believe in this country, was opened on
Saturday in the presence of a number of gentlemen who take an interest in the
experiment. A quantity of stone weighing sixteen tons, taken from the ledge
belonging to the Bunker Hill Association, and loaded on three wagons, which
together weigh five tons, making a load of twenty-one tons, was moved with ease
by a single horse from the quarry to the landing above Neponset Bridge, a
distance of more than three miles. The road declines gradually the whole way
from the quarry to the landing, but so slightly that the horse conveyed back
the empty wagons.... Sketch of the Granite Railway3 |

Once the stones were maneuvered onto a
pallet the car would be backed over it. Chains ran to a geared lifting mechanism
atop the car. One man could raise a six-ton block above the track for
transport.6
An
inclined plane brought the blocks down from the quarry to the railroad. An
endless chain and pulley system controlled the descent and returned the empty
cars.
