INTRODUCTION 11 



about the future possibilities of the cinematograph 

 in connection with science and education. 



The remarkable and unique application of the 

 cinematograph to obtaining details of submarine 

 life, the story of which will be told in these 

 pages, reflects the greatest credit on the persever- 

 ance and ability of the Williamson brothers, who 

 succeeded in perfecting the apparatus for taking 

 submarine motion pictures — truly a wonderful 

 achievement. The illustrations reproduced in this 

 book are taken from photographs filmed by the 

 Williamson Submarine Expedition. They enable 

 us to understand the apparatus employed, and 

 bring before us the panorama of a marvellous 

 submarine journey of thirty leagues along the 

 floor of the ocean. We shall read about the 

 famous Marine Gardens which form one of the 

 great attractions of Nassau, in the Bahamas, and 

 can picture in imagination the indescribable 

 beauties of the deep. Nature's wonders, whether 

 in plant life or in animal life, in their myriad 

 forms are placed before us. Scenes connected with 

 sponge fishing and coral fishing have been photo- 

 graphed ; we witness a diving scene ; and, probably 

 the most wonderful of all, we get a pictorial 

 representation of a desperate life-and-death struggle 

 between a daring swimmer, armed only with a 

 knife, and a huge, blue, man-eating shark, the 

 terror of the Bahama waters. This is undoubtedly 

 one of the most thrilling scenes ever beheld by 

 human eyes.
