Geological Survey of New Jersey. 1 — The Annual Report of 

 the State Geologist for the year 1894 contains an account of the pro- 

 gress made in the study of the surface geology, by R. D. Salisbury; a 

 report on the artesian wells in southern New Jersey, by L. Woolman, 

 and a statement of the results of the surveys made with reference to 

 ascertaining the forest area of the state, by C. C. Vermeule. 



Mr. Salisbury makes an especial point of the influence that " stag- 

 nant ice " has had upon the deposition of the stratified drift of the 

 valleys of the northern part of the state. In his description of Flat 

 Brook Valley he remarks that " the form of topography characteristic 

 of this valley, and of stagnant ice deposits in general, is the following : 

 A broad and somewhat swampy flood plain in the axis of the valley 

 is bordered on one or both sides by a strongly-marked kame belt a 

 few rods in width. This kame belt is lowest near the axis of the valley. 

 It rises in the opposite direction, and finally grades into a flat-topped 

 terrace." These terrace differ from normal river terraces pr 

 the fact that the slopes which face the axis of the valley are not erosion 



The forestry report includes a paper on the forest conditions of south 

 Jersey, by John Gifford. The interest of this paper centers in the 

 practical suggestions it contains as to the treatment of forest lands, 

 both for their preservation, and for pecuniary return for money and 

 labor spent in their care. The paragraphs on Forest Influences, and 

 Forest Economics should, in the interest of the people, be quoted in 

 every local paper of the State. 



Nine page-plates are used for illustrations, and a geological map of the 

 valley of the Passaic — topographic sheet 6 in envelope, accompanies 

 the Report.
