Jewett, then in tlie vigor of youth, enlisted in the army, and 

 continued in active service until peace was proclaimed. Dur- 

 ing this military service he was under General Scott, being in 

 the brigade of that celebrated soldier, and received promotion 

 for his gallantry as exhibited on various occasions. He was in 

 the battles of Luudy's Lane, Chippewa and Fort Erie, and at 

 the latter his courage was notably conspicuous. He served his 

 country with distinguished fidelity and bravery, and the com- 

 mendation of his commanding general was bestowed upon him. 

 The war with Great Britain being over, and about this time 

 the South American republic of Chili, then a province of Spain, 

 having revolted against the Spanish rule, Jewett, and a few 

 others of his companions-in-arms chivalrously espoused the 

 cause of the Chilians, and pledged their services to the Chil- 

 ian leader, General Carrera, in behalf of Chilian independence. 

 Crossing the South American continent from Buenos Ayres to 

 Chili, the passage of the Andes was made in a most inclement 

 season and at great peril. When near the crest of the cordil- 

 lera a fearful snow storm of four days' duration was encoun-

 it was with great difficulty he saved himself from freezing. Ar- 

 riving in Chili, he took command of the cavalry, and served 

 with distinction until the successful close of the war, when he 

 sailed for Rio Janeiro, and returned to his native village in 

 1818. 



Soon after he married a woman of superior culture and char- 

 acter, Elizabeth Arnold, of Westmoreland, New Hampshire, 

 who proved not only a devoted and affectionate wife, but a 

 sympathetic companion and an appreciative associate in his 

 scientific labors, for whom he ever manifested a most tender 

 regard. In 1826 he removed to Fort Niagara, where he re- 

 mained in charge seventeen years, his leisure houi^ occupied 

 with the study of the natural sciences ; he also improved 

 the advantages which the locality furnished by making a col- 

 lection of ethnological material pertaining to the American 

 aborigines. In 1843 he removed to Lockport, New York, and 

 his entire time was now given to the study of geology. In this 

 connection he travelled extensively throughout the United 

 States, including several journeys to the Lake Superior coun- 

 try in the years, 1844, 5, 6, where he was engaged in the
