their going, besides rendering the ship 

 helpless, much damage was done and twice 

 at least a fine ship endangered. 



But speed was demanded and again came 

 the triumph of speed until we reach, by 

 gradual but definite stages, the splendid 

 Mauretania in 1907. For more than twenty 

 years she remained supreme amongst liners, 

 but then came the German ships Bremen 

 and Europa and beat the old Cunarder. 

 Even so she notched over 29 knots, more 

 than 30 miles an hour, when extended. 



Warships have already surpassed the 

 Mauretania and the forty mile an hour has 

 been well passed. 



But speed on the water belongs not to 

 steam, but to the petrol engine. Here we 

 have again the break between useful and 

 spectacular speed, between a great ship 

 with huge earning power and the splendid, 

 but not profitable, motor boats like Miss 

 America and Miss England, the late Sir 

 Henry Segrave's wonderful craft which 

 easily beat all records in the spring of 1929 

 and 1930.
