appropriated $20,000 for the construction of a screw-pile structure out in the bay, Thomas Point Shoal Light . With an additional $15,000 appropriation in 1875, the light was built and activated in November of that year. It took 30 workers to set each cast iron beam into the Chesapeake Bay's bottom. Ice was a perpetual threat to screw-pile lights on the Chesapeake, and in 1877 the original lens was destroyed when it toppled by shaking from ice floes. This lens was replaced, and the additional piles and
