 this branch. 



" Blessed with an accurate and retentive memory, he 

 had accumulated by extensive reading and intercourse with 

 intelligent men at home and in different parts of our 

 country, large stores of precise and miscellaneous informa- 

 tion, from which he drew freely on appropriate occasions. 

 He was fluent in conversation, and ready in debate, unsen- 

 sual and unselfish in constitution, placidly cheerful in dis- 

 position, and always self-possessed and respectful in his 

 deportment to all. He quickly made friends, and was rarely 

 deserted by any whom he had once attached to himself. 

 He was considerate towards his inferiors, charitable to the 

 indigent, generous to the unfortunate, and ever ready to 

 contribute from his stores of knowledge to assist others in 

 their pursuits."
