Howard loves to visit his grandparents in Sutter Creek, California. Nestled deep in the Sierra foothills, the old mining town provides a glimpse of the Gold Rush days. One can almost see the prospectors galloping down the hill, their saddlebags filled with gold nuggets, or feel the heat of a pour day at the water-powered iron foundry, where equipment was made to accommodate the rush to mine gold from the hills. The old Knight Foundry is Howard's favorite building on Eureka Street. Built around 1873, the foundry still operates today. Invited inside the heavy rolling doors, Howard meets iron men of the past and present who show him their craft: how patterns are created, molds are made, and molten iron is poured into shapes to make everything from huge water wheels to delicate machinery parts. Seen through the eyes of a modern-day apprentice, this fascinating look at one of America's earliest foundry machine shops provides readers with a wealth of information. Engineering, design, history
