8 REPORT OF NEW JERSEY STATE MUSEUM. 
“The rocks, clays, peats, sands and fossils should be characteristic of for¬ 
mations, strata, beds and layers. The minerals, ores, rocks, &c., of economical 
value, should be characteristic of localities, such as deposits, mines and quarries. 
“Label each specimen (in accordance with the accompanying label) with its 
name (when known), its precise locality, date of collection and name of col¬ 
lector, and carefully wrap it in strong thick paper. 
“Let the label of each specimen refer to the particular page of a note-book 
on which it is described. Carefully pack each series of speciemns in strong¬ 
boxes, in such manner that their surfaces cannot come in contact or be scratched 
or injured by rubbing together The weight of each box should not exceed 150 
pounds. Choice specimens of crystallications and fossils should be wrapped in 
cotton and packed separately. 
“Prepare a list of specimens in each box, numbering each to correspond with 
a number on the outside of the w r rapper, and place it on top of the specimens, 
when the box is filled. Mark distinctly, and number each box to correspond 
with the note-book in which the specimens are described, and address it as 
follows : (-) 
“Whenever an opportunity may allows collect specimens of Natural History, 
such as plants, birds, animals, reptiles, fishes, insects, bugs and infusoria. Pre¬ 
serve and pack them carefully, in accordance with the accompanying 
directions.” 
The present Geological Survey was established in 1864, with Dr. 
George Cook as State Geologist. During the earlier years of Dr. 
Cook’s Survey, the work was all carried on from Rutgers College, New 
Brunswick, and such specimens as were collected were deposited in the 
College Museum. 
The Centennial Exposition in 1876 gave opportunity for making ex¬ 
tensive collections, as is shown by the following extract from the An¬ 
nual Report of the State Geologist for 1875: 
“Collections of representative specimens of rocks, ores, minerals, soils, 
fertilizers, building stones, glass sands and other natural and useful products, 
have been needed for our State collection and for institutions of learning. 
The demand for such specimens, in order to exhibit properly the richness and 
variety of the natural products of New Jersey at the approaching Centennial 
Exposition in Philadelphia, has necessitated making the collection this year.” 
“Professor J. C. Smock, with two assistants, has been steadily at this work 
since July 7th. The collection of rock specimens, iron and zinc ores and 
minerals, in all the northern part of the State and in the clay district, is 
finished. Specimens have been collected from at least 370 localities, one hun¬ 
dred of which were iron mines, and the specimens number more than tw r o thou¬ 
sand. There are still about one hundred localities to visit, and perhaps three 
hundred specimens to collect, and when this is done the series wall be completed 
as fully as desirable at present. 
“The specimens for the Centennial will be arranged in the State Cabinet at 
Trenton this winter, and removed to the Exposition in the spring. At the close 
of the Centennial they will be brought back to the State Cabinet and arranged 
there for permanent exhibition. 
“Duplicate specimens have been collected for the geological museums at 
Princeton and Rutgers Colleges.”
