Dog Holes

A single round hole on the face of this piece of granite is called a dog hole. Large granite blocks typically had a dog hole drilled into each end to hold the tips of giant hooks called dogs that were suspended by cables and chains from a derrick. The loop of chain tightened the grasp of the dogs as the block of granite was lifted from the quarry.

Once the block reached the surface, it was moved by oxen, horses or train to nearby sheds where men shaped it into paving blocks, curbing, building stone or ornamental pieces. Here at Halibut Point granite was transported directly to the wharf at Folly Cove where it was then shipped to its destination.
