THE GEOLOGICAL SURVEY EXHIBIT AT THE CENTENNIAL EXPOSITION 
AT PHILADELPHIA., 1876. 
This exhibit consisted of specimens of building stones, roofing 
slate, flag stones, limes, cement, &c., besides 256 specimens of iron 
ores; 20 specimens of zinc ore, 7 specimens of copper ore, 26 speci¬ 
mens of potters clay and glass sand, 10 specimens of barytes, manga¬ 
nese, 20 or more specimens of fire brick, pottery, alum, glass, &c. 
There was also a collection of characteristic fossils, 24 maps and pub¬ 
lications of the Geological Survey, &c. 
The following award was conferred: 
“GEOLOGICAL SURVEY OF NEW JERSEY. 
“Prof. George H. Cook, State Geologist. 
“Report—Large, well selected and well arranged collections, showing (1) all 
the rocks of the various formations known in New Jersey, including the potters 
clay and the green sand ; (2) the ores of iron and zinc, and the products of 
their metallurgical treatment; (3) the building stones; (4) a fine collection 
of rare crystalline minerals of the State ; (5) plans illustrating the mode of 
occurrence of the magnetic iron ores, a model of the Franklin Furnace zinc 
mine, and the geological maps published by the State Survey; the whole giving 
a very complete and most instructive view of the scientific and economic 
geology of New Jersey.

AGRICULTURAL EXHIBIT. 
“The Geological Survey furnished specimens of soils, sub-soils, marls and 
other natural fertilizers, and a collection of all the woods growing in New 
Jersey for this collection. It contained samples of 114 soils and sub-soils, 
representing the kinds found on the several geological formations and from all 
parts of the State, seventy-nine green sand marls, four calcareous marls and 
seventeen fertilizers, as shells, lime, muck, &c. 
“These specimens were exhibited in glass bottles, enough of each being put in 
to show its characteristic appearance. They represented very fully the green 
sand marls and miocene marls in nearly all their common forms, as found in 
the clay marls, in the lower, middle and upper marl beds, and in the miocene 
localities. The soils of the marl region were also well represented by good 
and fairly average specimens, showing all the varieties of soil found in that 
part of the State. From northern New Jersey we have a few good soils, 
typical of large areas of some of our best and most productive land. These 
make the nucleus of a collection which will represent all the varieties of soil 
found within our limits, and they are all good specimens for chemical examina¬ 
tion and study. 
“Of the woods there were seventy-two specimens, brought from one hundred 
different localities, and each specimen was represented in three sections, one 
being cut crosswise, one lengthwise and the third aslant. It is a fine collection 
of native woods. At the close of the exhibition these specimens were returned 
to the museum of the Geological Survey at Trenton, for permanent exhibition 
and are now arranged there.”*
