 Approved March 7, 18S8. 



Under the act of 1864 work in the survey was resumed with the 

 purpose of collecting together all that could be found relating to the 

 geology and natural resources of the State in the four years allotted 

 to the work, and to prepare and put these in such form as might 

 be most useful and acceptable to the people. Short pamphlet reports 

 of the conditions and progress of the survey were made every year 

 to the governor. That of 1864 contains 24 pages, with a colored 

 geological map and a profile of the rocks of the State, each in an 

 octavo page. The report of 1865 contains only 12 pages; the one 

 of 1866 has 27 pages ; and that of 1867 has 28 pages. The matter in 

 these, however, is all reproduced in the Geology of New Jersey, which 

 was printed in 1868, and is the only report of that year. 



The organization of the survey for those years was as follows: 

 George H. Cook, State geologist ; John C. Smock, assistant geologist. 

 Maj. T, B. Brooks was engaged in topographic and magnetic sur- 

 veys of iron mines and iron-ore lands in 1864; Dr. David Murray 

 was engaged in preparing projection for a new map of the State, and 

 in collating and revising in the field the materials for such a map in 

 1864-05; Dr. Charles C. Abbott voluntarily devoted himself to the 

 preparation of catalogues of the vertebrate animals of the State dur- 

 ing the j^ears 1864-1867; and G. M. Hopkins, civil engineer, com- 

 piled the maps for the use of the survey and for publication, using 

 such material as was available from former surveys and from old 

 maps. He also surveyed and drew a topographic map of about 80 

 square miles of the district of Morris County in which the largest 

 iron mines are located. His work was done in 1865-1867. Edwin H. 

 Bogardus was employed as chemist through the years 1866-67; 

 Francis C. Van Dyck was engaged in chemical researches during part 

 of the years 1866-67; Paul Cook was occupied in tracing lines of 

 magnetic attraction and beds of iron ore in 1866-67; lines of mag- 

 netic attraction were also traced by John Hance and others. 



The work of the four years was completed as proposed, and at an 

 expense within the appropriation made for it. The report, however, 

 was not ready for publication, and the section requiring its com- 

 pletion in four years was repealed March 24, 1868. 



The report, which was issued the latter part of 1868, was entitled 

 The Geology of New Jersey. It is an octavo of xiv and 899 pages
