 not remarkable for eloquence, but he always imparted to 

 his hearers something of his own passion for botany. 



Mr. Nuttall was called to Harvard College at the end 

 of 1822. The endow^ment not being sufficient to support 

 a professor, he was appointed curator of the Botanic Garden, 

 with light duties of instruction, so that the greater part of 

 his time was devoted to study and to the culture of rare 

 plants. In Cambridge, as well as in Philadelphia, he led a 

 retired life."^ 



Mr. Nuttall became dissatisfied with his position at

 United States and Canada," in two volumes of about six 

 hundred pages each and illustrated with excellent wood-cuts. 

 While at Cambridge he contributed papers to various scien- 

 tific journals, and issued a text-book entitled " An Introduc-

 bridge, he resigned his position and spent the time before
