GEOLOGICAL AND NATURAL HISTORY SURVEYS. 809 



with the general course of the river at Trenton, and thence prolonged 

 to the seashore, south of Barnegat; fourth, a section across Glou- 

 cester, reaching from the Delaware River, at Camden, to the sea- 

 shore near Leeds Point; fifth, a tract traversing Salem, Cum- 

 berland, and Cape May counties, from the Delaware to the seacoast. 



This plan as carried out has furnished the basis for all the geo- 

 logical investigations which have since been made in the State. 



In his report for 1837 the general plan outlined above was ad- 

 hered to, but investigations w-ere conducted with an eye to more 

 system and greater scientific accuracy. In place of "crossing the 

 strata, as hitherto, in certain lines with a view to determining their 

 more obvious contents and relative situations, they have this year 

 been traced also longitudinally, in order to delineate on the map, 

 with precision, their true boundaries, and to behold throughout tlieir 

 entire area every modification their rocks or mine)'al deposits might 

 present." 



It w^as noted that considerable chemical work was done and many 

 specimens collected to form a cabinet for the better elucidation of the 

 final report and geological map. No library was formed. 



The field work of this survey was practically finished in 1838 and 

 the final report printed in 1840. 



Eicpe7ises. — The entire cost of the survey, exclusive of })ublication, 

 would appear to be— 1835, $1,000: 1836, $2,000; and 1837, $2,000. No 

 appropriations were asked for after that for 1837.

SECOND SURVEY UNDER WILLIAM KITCHELL, 1854-1856. 



In his annual message to the legislature, dated January 17, 1854, 

 Gov. R. M. Price made the following recommendation : 



It is reported thnt valuable mineral depos'ts nre frequently discovererl by 

 foreifmers, and lunds purchaspd from our landholders at nominal prices. A 

 thorough geological survey of the State would doubtless discover mineral de- 

 posits to the advantage of our citizens and prevent the speculation now prac- 

 ticed upon them, and increase the value of taxable property beyond the cost 

 of the survey and promote the great interest of agriculture. Fifteen years ago 

 a survey was made which does not meet the progress of scientific discovery. 

 The benefits and practical returns from that survey greatly increased our 

 agricultural productions. The value of marl previous to the survey was un- 

 known, and its use as a fertilizer has greatly enhanced the value of lands.
