640 Life of Count Rumford. 



age. Professor Treadwell first made cannon of steel 

 and wrought iron, of large calibre, in a manner since 

 repeated by Armstrong, and now in common use. For 

 this he received the Rumford Medals from the Ameri- 

 can Academy. He has made valuable experiments on 

 the force of fired gunpowder, which, together with 

 some valuable papers on Force, have been printed in

 to the Rumford cabinets at the College.

 best characteristics of mind and genius. We recall the 

 time of his own boyhood, when with young Baldwin 

 as his guide and patron, after long walks, he reached the 

 halls of the College, and there nourished the ardor 

 which gave the impulse to his mature life. We recall 

 also another scene in which he appears, a few years after, 

 on the same spot. When in early manhood, amid the 

 passions and alarms of war, he was brooding over 

 the calumny and injustice of which he felt himself to be 

 the subject, he hastened to Cambridge, then a camp, 

 that he might help in removing from the College shelves
