 His replacement, Charles A. Ballantyne, had a difficult assignment recruiting workers due to the widespread negative reaction to Trewavas' death, and a general desire by the public to end the project.Ballantyne was eventually able to secure a group of quarrymen who knew nothing of the tragedy, and was able to resume work on the rock.Transportation to and from the rock involved the use of a derrick line attached with a breeches buoy, and in May 1880, they were able to completely blast the top of the rock to allow the construction of the lighthouse's foundation.
