REMAINDER OF GLACIATED RED SANDSTONE. 



In the four topographical subdivisions last considered, viz., 

 the Passaic Valley, Watchung Mountains, Hackensack Valley 

 and Palisades Mountain, we have included all of the glaciated 

 red sandstone except the portion east of the Watchung mountains, 

 extending from Newark and Orange southwest to the moraine 

 at Plainfield and Perth Amboy. This remaining country, drained 

 by the Elizabeth and Rahway rivers, is heavily covered with 

 drift in irregular hummocks and ridges, and is not specially 

 adapted for agriculture, but is being occupied by suburban homes 

 in the north, while southerly it is the well-known clay district 

 of Middlesex county. In general, about 25 per cent, of the 

 upland area is in forest. 



North of Westfield and Fanwood chestnut prevails, mixed 

 with oak, hickory, maple, etc. The wood looks thrifty. Some 

 is less than 20 years old, but more is older, and averages from 6 

 to 14 inches diameter, and 40 to 65 feet high. Just northwest 

 of Westfield some trees ran up to 24 inches diameter and 70 feet 

 high. Northwest of Cranford some ranged from 4 to 1*2 inches 

 diameter and 40 to 50 feet high, some 6 to 12 inches by 45 to 55 

 feet, and a few large trees were mixed in which ranged up to 20 

 inches by 70 feet. Along Rahway river the timber is small, 

 having been culled out. In the swamp at Union it is poor, with 

 much white birch. North of Roselle it was 6 to 24 inches and 

 50 to 75 feet high with some few pieces smaller, but all 

 healthy. All of the above is oak, chestnut and hickory, princi- 

 pally. 



Southeast of Fanwood it is of the same general character ; 

 large and thrifty. Near Netherwood it is a little smaller. 

 Southward from Westfield and Cranford the same general condi- 

 tions prevail, but the timber of Ash swamp is smaller, 2 to 14 

 inches by from 20 to 60 feet. Southeast of the Pennsylvania 

 railroad, between Rahway and Elizabeth, pieces of timber ranged 

 as follows : 2 to 6 inches by 20 to 40 feet ; 6 to 24 inches by 50 

 to 60 feet ; 6 to 20 inches by 40 to 50 feet ; and 8 to 14 inches 

 by 35 to 55 feet. Near New Dover the smallest timber ranged 

 2 to 7 inches in diameter by 10 to 20 feet high, and the largest 

 8 to 24 inches by 40 to 70 feet. The various parcels ranged 

 through all intermediate sizes.
