New Jersey. 
The space- was smaller than the mining interests of New 
Jersey required, but it was neatly arranged. A relief map 
of the state on the topographical basis of the (oast and Geo- 
detic Survey, the horizontal scale being one inch to the mile or 
(;: , .^ G0 . and three vertical scales, presents the salient features 
of this important commonwealth. A very characteristic and 
interesting collection of minerals from Sterling Hill and 
Mine Hill, including calamine, rhodonite, willemite and frank- 
linite, forms the principal feature of interest in the exhibit. 
It is to be regretted that at the times of the visits to tlii~ 
State exibit neither catalogue, description nor attendant 
were found. The assemblage of building stones was worthy 
of notice.
