Myth of the Ship-holder. 305 



layer of fresh water are all moving forward at the same rate. 

 Little, if any, of the rudder reaches down into the under- 

 lying salt water, and hence the vessel loses steerage. 



There is little else to be said concerning Ekmau's claim 

 to have explained dead-water. He had done so in a wonder- 

 fully clear and explicit manner. In his paper he refers to 

 the Myth of the Echeneis, and notes that the phenomenon 

 of dead-water effectually clears it up. So it does, and 

 another myth of the ancients is dissipated in thin air under 

 the searching investigation of modern science.
