leaves of Q. rubra and also those of Q. 2'exana on and beneath 

 the same tree ; and also many intermediate forms. It was not 

 onl_y one tree, hut man}', which showed these differences. 



Quercus rubra attains a large size in Eastern Texas ; but west 

 of the Trinity River it is seldom more than two feet in diameter. 

 Its wood here is harder, firmer and better than that of the 

 Northern red oak. 



About two miles from Raleigh, North Carolina, on the F'ayette- 

 ville road, in 1858, I measured a Quercus rubra which was 20 feet 

 8 inches in circumference at three feet from the ground. It was a 

 low tree, with a remarkable spread of very large limbs, whose 

 length on the south side was 72 feet and 71 feet. The longest on 

 the north side was 66 feet. Near the base of its limbs at ten feet 

 from the ground it was 27 feet in circumference. The circum- 

 ference of the largest limb, at two feet from the trunk, was 9 feet 

 7 inches. Another limb was 7 feet 7 inches in circumference. 



In September, 1859, I measured a Q. rubra in Wilcox County, 

 Alabama, which was 24 feet 7 inches in circurnference at three 

 feet from the ground. It was a tall, well-developed, healthy tree. 

 Another one not far distant was 18 feet 2 inches in circumference 

 at three feet. In the town of Romulus, Seneca County, N. Y., 

 I measured another, in 1865, which was 17 feet 2 inches in in cir- 

 cumfererence at three feet high. Most of the large red oaks of 

 the Northern States have been cut down to make staves for flour 

 barrels, etc.
