Jersey began in 1854, when lie became associated with the late 
Dr. William Kitchell, state geologist. He was assistant geol- 
ogist in charge of the southern division of the state for three 
years and made reports on the green-sand marl beds, on the 
clay beds, on the coast changes, and a final report on the 
county of Cape May. The most notable results of his survey 
were the discovery of a subsidence of the coast and the strati- 
graphical relations of the green-sand marl beds. A paper on 
the coast changes of level was read by him at the meeting of 
the American Association Adv. Sci. in Montreal in 1857. The 
relation of the several marl beds to one another and to the 
associated sand beds was worked out by him, and the stratig- 
raphy was proven to be correct by the instrumental observa- 
tions which he had made. Thus, almost at the outset of his 
long connection with the state survey, and his successful 
administration, he began the topographic work which has 
made that survey so useful to the people of New Jersey, and 
which upon its completion reflected so much credit and honor 
upon him. The structure of the whole southern part of the 
state was practically made out at that time. The studies of 
succeeding years have demonstrated the correctness of the 
stratigraphical order in the green-sand marl beds and added 
to the geological column the overlying and newer beds. 
The geological survey was suspended from 1856 to 1863. 
The state legislature put the property of the survey in his care 
in 1863, and he made a report of his work to the State at the 
close of the season. The advantages of a geological survey 
and the desirability of completing it, moved the Legislature 
to order its resumption and he was made state geologist by an 
act of the Legislature passed in 1864. He held this position 
for a quarter of a century — and to his death. The results of 
the first quadrennial term were published in 1868 in the ''Geol- 
ogy of New Jersey." ' They were found to be of so much 
value to the people of the state that the survey w^as ordered to 
be continued a further term of four years. Supplementary 
acts passed by the Legislatures of 1872, 1876, 1880 and 1885 
authorized the continuance of the survey. The almost unani- 
mous votes in passing these acts show the confidence placed 
in him as the head of the survey ; and the long official tenure
