Page 80. Quercus lyrata. The largest tree measured stood 

 near the town of Mount Carmel (almost within the corporation), 

 and was 8| feet in circumference. The height was estimated at 

 between 90 and 100 feet. 



Page 81. Quercus macrocavpa. A felled tree, in bottoms just 

 above Coffee Creek (Wabash county, Illinois), measured in Octo- 

 ber, 1882, was 139 feet long, the trunk 87 feet clear, the diameter 

 across top of stump (at 5J feet from ground) being 4 feet, and 

 only 1 foot less at end of last cut ! 



Page 81. Quercus Michauxii. In the spring of 1883, I found 

 this species very abundant, in fact, the prevailing "white" oak 

 in certian portions of the bottom lands near Wheatland, Indiana. 

 On a tract not exceeding 10 acres in extent, 16 trees, including 

 apparently all of this species growing in that particular locality, 

 were measured, with the following result. Being, with a single 

 exception, all standing trees, it was necessary to estimate the 

 height and length of the trunk : 



Average, 11.83, or nearly 4 feet in diameter. 



\ The general character and appearance of this tree are those of 

 both Q. Muhlenbergi and Q. bicolor. It is most like the former 

 in foliage (which, however, is much more coriaceous, darker in 

 color, and more velvety beneath), but is more like the latter in 

 form, being one of the most robust of all the oaks, while Q. 

 Muhlenbergi is decidedly the most slender of the white oak group. 

 In the character of its bark, it is like other species, exceedingly 

 variable, some specimens agreeing exactly in this respect with 

 Q. Muhlenbergi while others could not be distinguished from Q.
