 bridge. While engaged in his college studies, he also made 

 a large collection of insects ; and made meteorological ob- 

 servations for the Smithsonian Institution which have re- 

 ceived much commendation. 



While yet at Acadia College pursuing his studies, Hartt 

 entered into correspondence with the author of this sketch, 

 and before he graduated, we made a visit together to the 

 mineral localities of Minas Basin and the adjacent shore of 

 the Bay of Fundy, where the rich harvest of zeolites and 

 showy varieties of quartz minerals, set free by the frost of 

 winter, still attract numerous summer visitors. This visit 

 was the beginning of a more intimate acquaintance, which 

 was continued when Mr. Hartt moved to St. John. 1 



Later in this year (1860) Mr. Jar vis Hartt removed with 

 his family to St. John for the purpose of establishing a 

 Young Ladies High School, which he carried on successfully 

 for many years. For some time his son aided him in con- 

 ducting the school, but the son's love for his favourite stu- 

 dies was such, that every spare moment which could be 

 snatched from the immediate duties of the school, was given 

 to explorations in the neighborhood of the city, and the 

 gathering of a rich harvest of fossils from the ballast of 

 vessels, arriving from the west coast of Ireland, the Medi- 

 terranean and elsewhere. 



When Mr. Hartt came to St. John, but little was known 

 to the Scientific World of its geology. Some twenty years 

 previously the late Dr. Abraham Gesner, then employed on 

 the Geological Survey of New Brunswick, had traversed the 

 neighborhood of the city of St. John, and had referred the 

 rocks of that vicinity to the " Grauwacke Formation," with 

 the reservation that certain portions near the city were " im- 

 perfect coal measures." He made the latter part of this 

 statement in consequence of the discovery of a fossil tree 

 in the sandstones East of the city. Dr. Jas. Eobb of King's 

 College, Fredericton. the successor of Dr. Gesner in the 

 study of the geology of New Brunswick, pronounced the 

 same rocks some years later to be Upper Silurian. It re-
