INTRODUCTION. 5 



but it is the length of line over which the patient marine surveyor has h€id 

 to toil in the execution of his arduous but most important duties. These 

 figures, however, but faintly express, as indeed anything we could say 

 here would fall short of teUing, how nuch has been done to brines the 

 hydrogi-aphy of this ocean to its present condition. It is enough here to 

 draw the seaman's attention to a few of the results of those costly and 

 laborious surveys by which he benefits. 



Of the 62,834 miles of sea-coast, the English Government have surveyed 

 about 23, COO miles, and foreign governments about 31,600 miles, the re- 

 mainder being unsurveyed. 



Of the coasts of Europe, the English Admiralty and Ordnance have only 

 surveyed about 4,0©0 miles out of 19,000 miles. 



The following Table of the details of the length of the coast, &c., of each 

 country, is therefore given rather as a matter of cm-iosity than material 

 utility, and will form a fitting introduction to the Geographic Tables 

 which follow.
