we fondly think, in the Philosophical Society, that they were 

 elected presidents because they were members of the Philo- 

 sophical Society. (Laughter.) 



And, I might remark that the recent election of President 

 Wilson has left all of the other members of the society in a very 

 receptive mood. (Applause.) 



In 1906 we celebrated the 2OOth anniversary of the birth of 

 Franklin, a very notable celebration, when addresses were made 

 by the most distinguished men of our own and other countries, 

 including the Ambassador who, unfortunately, has just left us. 

 There were also three other things that occurred at that time 

 that are rather notable. We published the calendar of Franklin

 the Philosophical Society. We have also the instruments that 

 were used by these distinguished engineers at that time to trace 

 the boundary line between the states of Maryland and Pennsyl- 

 vania the well known Mason & Dixon Line, which, I am glad 

 to say has been wiped off the political map, though it were by the 

 bloody sponge of war. 



We have a number of the earliest explorations also among our 

 archives : Dunbar's exploration of the Red River in 1804-1805 ; 

 the original field notes of the Lewis & Clark celebrated expedi- 

 tion into the great Northwest, the first that ever penetrated to the 

 Pacific Coast, deposited with the society at the request of Jeffer-
