Introduction 



Near Argostoli, on the southern coast of the island of Cephalonia, in 

 Greece, a stream of salt water has for an unknown period of time left the 

 almost tideless sea, and, flowing inland with a volume sufficient to fur- 

 nish water power to two mills, finally disappeared in fissures represent-

 the normal conditions of drainage and the disposal of the immense quan- 

 tities of water sinking into the limestone have long been themes for spec- 

 ulation. It remained for F. W. and W. 0. Crosby,* however, to offer
