174 LIFE OF BENJAMIN SILLIMAN. 



from recollection, 1 have been surprised by the fidelity, 

 with which that faithful prompter, memory, summons up 

 scenes and thoughts that have apparently long since passed 

 into oblivion, and have faded away from our minds. Asso-

 mountain, I had nearly reached its western extremity, when 

 I was induced by a place that looked, very promising,
