Bystanders watch as a column is set along the Wall Street elevation. The derrick holds the third column from the east while mechanics align the pre-drilled holes for the rivets. The two man crew just behind the hoarding at the left edge of the photo may be the forgeman and his helper preparing rivets. It is also likely that the column is being placed and held in place temporarily with bolts or pins and that the two man crew is excavating for the sidewalk vault under Wall Street.
