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 energy would not allow him io 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 io 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 Verrill, Morse, Putnam, Hyatt, Scudder and St. John, 

 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
