mitted the crew to go down into the already submerged sphere was 

 of frail construction. One thing was certain in any case : the second 

 solution called for a much more expensive machine than the first. 

 That is why, when building the FNRS 2, we gave up the idea from the 

 outset. It will be shown later that we were able to adopt it in the case 

 of the Trieste, thanks to the help that we received in Switzerland and 

 Italy. 



The third solution is a compromise: the bathyscaphe is built in 

 such a way that it can be taken in tow : it is loaded, empty, on to a 

 cargo-ship which transports it to the port nearest the diving-place, 

 and there it is launched. It is filled with petrol: then, when the sea 

 allows, it is towed to the place selected. That is the solution adopted for 

 the FNRS j which, as is known, was transported by cargo-ship from 

 Toulon to Dakar, where it was filled with petrol before going down 

 to 2200 fathoms. 



There remains one question to resolve: should the bathyscaphe 

 be loaded in one piece on the cargo-ship, or should the cabin and the 

 float be shipped separately ? This depends upon the cargo-ship itself.
