James Lafferty, U.S. Patent 268503
“ An upper story, J, may be supported on the body B, access whereto is had from the floor a by means of stairs c, which are properly located in the walls of the body B and sustained in position, said story J being in the form of a howdah, which, completing the semblance of a bedecked elephant, acts as the observatory of the building. It will be seen that the structure is novel and unique. The body is supported on hollow legs, which are strong and enabled to endure the great weight superimposed upon them. ”
