Another stands on the place of Mr. A. P. Morgan at 

 Preston, also in Hamilton Co. In 1892, while collect- 

 ing Ohio forest trees for the World's Fair, Prof. Keller- 

 man found a tree at Brownsville, in Licking Co., but 

 it was cut down soon afterwards. The fourth one was 

 found by myself on a lot of about 20 acres, on which 

 there are still 30 or 40 forest trees, almost in the heart 

 of Columbus. 



This oak and the one from Preston, are the only 

 ones of which I possess both leaves and acorns, and 

 are therefore the onl}^ ones, on which I can form an 

 opinion as to their parentage. 



The Columbus oak is about 2 ft. in diameter, and 

 30 or 40 feet in height, with a rounded and spreading 

 top, caused, no donbt, by an injury which it had once 

 received. The bark and the whole tree have the aspect 

 of Quercus rubra, and I have seen Red oaks, which I 

 supposed, seeing them from a distance, to be other 

 hybrids, but which proved, on closer examination to be 

 Quercus rubra. The leaves are perfectly smooth on 

 both sides, some of the smaller ones are entire with a 

 w^avy margin, some have one lobe, others more, while 

 most of the larger ones have three regular lobes on 

 each side, all tipped with a short bristle. The acorn 

 has the appearance of a small sized acorn of Quercus 

 rubra, but differs from it in having the nut smooth, 

 and sometimes marked with distinct longitudinal 

 stripes. 



The leaves of the Preston oak are larger and more 

 regular, the larger ones generally being entire. They 

 are also pubescent beneath like those of Quercus im- 

 bricaria, and have much larger marginal bristles. The 

 acorn is very small, being no larger than that of 

 Quercus velutina. The cup resembles the cup of 

 Quercus velutina or Quercus coccinea, while the nut is 

 of a red brown color, covered with prominent longi- 

 tudinal stripes like Quercus palustris. But as the 

 acorn of Quercus coccinea is rather larger, I think that
