"No operation in submarine engineering is more important or attended with greater personal risk than diving. The art has, however, been so far advanced, and the apparatus for diving has been so far perfected, that divers now descend to depths of over 100 feet. There are about thirty professional divers in the United States, and the annual mortality has been on the average about four of this number."
Wow. So far advanced and perfected that the annual mortality is just over 13 percent. Sign me up.
