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.^ 
Later in this year (1860) Mr. Jarvis 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 eveiy 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 Scientitic World of its geology. Some twenty jmars 
previously the late Hr. Abraham Gesner, then employed on 
the Geological Survey of New Brunswick, bad 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 Hr. Gesner in the 
study of the geology of New Brunswick, pronounced the 
same rocks some years later to be Upper Silurian. It re-
