| Description: | Bowers Quarry, Portland. Jack for lifting blocks of Portland Stone. The earliest known method of removing blocks of stone in the Isle of Portland was by means of hand-jacks, blocks being raised to hand-carts and hauled out of quarries up an inclined plane. Few of these hand-jacks now remain on the Island. Later the method of crab-winch and shear-legs was employed, until about 1850. |
