52 GEOLOGICAL SURVEY OF NEW JERSEY. 



large sumac was noted, 2 to 4 inches in diameter and 10 to 20 

 feet in height. On Jenny Jump mountain there has also been 

 some recent cutting of timber about the old silver mine. The 

 best growth is on the main ridge of the mountain, and it 

 includes some hemlock. The timber on the foot of the hills, 

 especially on the limestone, is inferior. A chestnut tree, 70 

 years old, measuired 5 feet in diameter at the stump, but was 

 rotten at the heart. About the foot of the mountain, in the 

 valley, oak, chestnut, cedar, ash and poplar were observed. At 

 Southtown some large sumac was noted, measuring from 2 to 6 

 inches in diameter and 10 to 25 feet in height. Just north of 

 Shiloh, at the foot of the mountain, there is a locust grove 

 covering about one and one-half acres, the origin of which was 

 not ascertained. Southward from Shiloh chestnut and oak 

 prevail, ranging from 2 to 16 inches in diameter and 10 to 45 

 feet in height, with some good timber near the Hope and Dan- 

 ville road. Southward from this highway, to where the road 

 crosses to Green's pond, there has been much cutting within 15 

 years, and the timber is now poor in quality. Just south of 

 Kishpaugh mine a chestnut stump showed 100 rings, and meas- 

 ured 36 inches in diameter. One ring was observed measuring 

 one-half inch in thickness. On the south end of Jenny Jump 

 mountain the timber is quite good, ranging from 6 to 18 inches 

 in diameter, and 25 to 50 feet in height. There has also been 

 some cutting here within 15 years. At the outlet of Green's 

 pond there is a tamarack swamp quite heavily timbered. Gen- 

 erally over this region of Jenny Jump mountain and Mount 

 Mohepinoke the steeper slopes are wooded, but some of the 

 gentler slopes have been cleared and are cultivated without 

 suffering from wash. It is generally the fact that there is little 

 or no evidence of wash where the Highlands ridges are 

 deforested on the slope, although it is true that almost invari- 

 ably the steeper slopes are well wooded. There is much more 

 wash on the slate ridges, shoM^ing that it is largely due to the 

 nature of the soil. 



Mr. L. V. Williams, of Danville, speaking of this region, 

 thinks that on an average timber is worth $20 per acre, and 

 most of the mountains have a growth ranging from 12 to 18 

 inches in diameter, with chestnut predominating, but there is
