Plant remains and insects, however, were not the only 
organisms discovered by Mr. Hartt in these interesting beds, 
for crustaceans also were found. These were of peculiar 
types and others found since in the same beds are not less 
remarkable. 
Hartt’s restless enei-gy would notallow him lo be content 
with field work alone, so in conjunction with several other 
young men of kindred tastes, in the city of St. John, he 
formed the ‘‘ Steinhammer Club” an association devoted to 
the study of Geology. Subsequently at the suggestion of 
Sir Wm. Dawson of Montreal, this club was changed into 
a public society under the name of the Natural History So- 
ciety of New Brunswick, whose meetings have been the 
means of sustaining an interest in the natural sciences in 
St. John, and in whose publications are recorded much that 
is of value relating to the Natural History of the Province 
of New Brunswick. — In this society Mr. Hartt took the 
warmest interest, attending its meetings, reading papers 
germain to its object, and devoting much material and time 
to the enlargement and arrangement of its museum. 
Absorbed as he was in geological studies Mr. Hartt could 
not long remain content with his work in the High School. 
Accordingly he resolved to seek a larger field for study and 
work. Prof. Louis Agassiz had then recently come to 
America, and had already become widely known on this 
continent, as a successful teacher and instructor in Natural 
History. To his Zoological museum Mr. Hartt resolved to 
go in order to complete his studies. He sold his Devonian 
collections to the Natural History Society of New Bruns- 
wick, and proceeded to Cambridge to avail himself of the 
great stores of material for study in Agassiz Museum, and 
to obtain instruction from that talented and most attractive 
teacher of Natural History. Here, with such kindred spir- 
its as Yerrill, Morse, Putnam, Hyatt, Scudder and St. JohnJ 
he devoted himself for several years to the investigation of 
Nature under the intelligent eye of Agassiz. 
The writer of this sketch had meanwhile commenced the 
study of the older slates at Saint John, whose age hitherto
