The Silent World is the first book of a series by the authors that chronicle the conception of OC SCUBA and the early adventures of JYC and his companions. It has been reprinted many many times in both hardcover and paperback editions (photo is of a Perrenial Library paperback). The one I am currently referencing is a hardcover copy published in Great Britian by Hamish Hamilton Ltd. 1953. 148 pg's with 64 pg's of photographs.
I will offer a brief synopsis of the main chapters but will leave the details up to the reader. What can I add anyways. But first a condensed set of quotes from chapter one that always brings a smile to my face:
"One morning in June 1943, I went to a railway station at Bandolon onthe French Riviera to collect a wooden case expressed from Paris. In it was a new and promising device... We hurried to a sheltered cove which would conceal our activity from curious bathers and Italian occupation troops...My friends harnessed the three cylinder block on my back... I looked into the sea with the same sense of trespass that I have felt on every dive... I went down to sixty feet. We had been there many times without breathing aids, but we did not know what happened below that boundary. How far could we go with this stange device?"
and thus, the modern era of OC SCUBA diving was born.

Epilogue.
Some people criticize JYC for some of his groups early disregard of the environment but what they did must be taken into account with the prevailing opinions/understanding of the day. If it were not for the evolution and popularization that SCUBA afforded Cousteau and others we might still hold many of those same values. In reading this, and other early diving accounts I am always struck by how much these pioneers were continually pushing the envelope of the unknown. They were literally "flying by the seat of their pants" and making things up "on the spot". At each step they had to confront what amounted to millenia of superstition and presumptions about the sea. In this book JYC gives us a glimpse of that audaciousness yet with a voice that is at times comical and very human. Modern diving owns a great deal to this inventor, adventurer, poet, educator, and it all starts here.
As you can probably tell I give this book 2 thumbs up!
