Fig. 67. {upper) The half-mile of solid rubber hose has now been unwound from its 

 spindle and coiled loosely on deck. One weak spot has been cleverly spliced by a friend 

 from the Wireless Station, and the four internal wires work perfectly, transmitting sound 

 and light. A squall is approaching, making diving impossible, and the bathysphere is being 

 lashed to keep it from rolling about. Fig. 68. {lower) Before a human goes down in the 

 bathysphere it must be sent for a test dive, deeper than the intended descent. The 400- 

 pound door is swung into place and fastened on.
