that had been removed, showing that the roots readily pro- 
duce a coppice. Attention was first called to these trees by 
finding twigs torn off and scattered over the ground bya 
heavy storm of wind. Among them were some carrying 
leaves of an unfamiliar kind of oak, which were soon traced 
to the trees from which they came. The trees were mixed 
with others, mostly oaks represented in the hybrid, within an 
area of a couple of acres. The soil was of a gravelly nature, 
almost exclusively bearing oaks and hickories, with an under- 
growth of hazelin the more open spaces. The hybrid trees 
were from fifty to sixty feet high, their bolls free from limbs 
for the first fifteen or twenty feet, except from the occasional 
presence of adventitious shoots. The largest tree was three 
feet nine inches in circumference at a foot and a half above 
the surface of the ground, just beyond the swelling occasioned 
by the roots. The rest were about a foot in diameter, 90 
nearly of the same girth and height as to indicate that they 
were of about the same age. The outer bark could not be 
distinguished from that of the typical shingle oak of the same 
age and size, being but slightly furrowed, close and rather 
smooth, and of a dark gray color. The trunks did not have 
the black, rough and deeply furrowed bark so characteristi¢ 
of the black oak even on small trees, for it begins to ie 
this character quite early in life. A section of the ¥ 
showed essentially the same characteristics as that of ns 
shingle oak, the inner bark being of a reddish or reddis 
yellow color.
