to succeed his father. President Jefferson 

 wrote this endorsement : 



''I have constantly refused to give in 

 to this metliod of making offices heredi- 

 tary. Whenever this one ])ecomes ac- 

 tually vacant, the claims of Jared Hand

 competitors. "Thomas Jefferson." 



In a matter respecting the conduct of 

 the keeper of Cai)e Henry lighthouse he 

 wrote : 



"I think the keepers of light houses

 sufficient authority for the removal of 

 the present keeper.

 mark harbors, inside channels, and dan- 

 gers. Along the navigable rivers numer- 

 ous post lights are maintained to indicate 

 the channels. 



For Xew York harbor and immediate 

 approaches alone 268 aids to navigation 

 are recjuired, including 46 shore lights, 

 2 light vessels, and 36 lighted buoys; 

 there are 192 buoys of all classes and 37 

 fog signals, including sounding buoys. 



A chart of Xew York harbor in 1737 

 shows not a single aid to navigation 

 there at that time. One may imagine the 

 difiiculties of Henry Hudson when in
