above the ground, the smaller about nine inches. As shown in the photo- 
graph, the trunks were separate to a height of about eight feet, where 
they were united by a large protuberance which seemed to have its origin 
in the larger tree, as it partially enveloped its trunk. A section of this 
connection would be of an irregular oval shape, the longer dimension in 
line with the axes of the trunks. This longer diameter would measure 
about two feet. The union seemed to be of a healthy, woody growth, cov- 
ered with rough bark. : 
Below the graft the trunks were about seven or eight inches apart and 
nearly parallel; above they diverged slightly. 
The lack of measuring appliances at the time of the examination pre- 
vents anything but an approximation of dimensions. 
Norres ON THE Cypress SwAMps oF Knox County, INDIANA. 
By Joon S. WriGHt. 
It has been stated frequently that in Knox County, Indiana, are the 
northernmost cypress swamps. According to the manual of Britton and 
Brown, the range of the cypress (Taxodium distichum (L), L. C. Rich) is 
given as “Delaware (possibly in southern New Jersey), Florida, west to 
Texas, north in the Mississippi Valley region to southern Indiana, Mis- 
souri and Arkansas.” Gray’s Manual also gives this range. The latitude 
of the swamps of Knox county is about 38° 30’, so that if cypress ranges 
over any considerable portion of southern Delaware it is in a higher lat- 
itude than that of Knox county, since Delaware extends from about 38° 
28’ toabout39° 50’. Cypress of New Jersey would also be above this latitude, 
since Cape May, the most southern point, is about 38° 50’. While it may 
be that the cypress swamps of Knox county are the most northern charac- 
teristic growths of this kind, they certainly do not mark the northern limit 
of the range of the cypress. The swamps of Knox county are located, 
so far as I could learn, almost wholly in the townships of Decker and 
Johnson, both southern townships, and bounded on the south by the White 
River. Decker Township, forming what is known as the pocket of Knox 
county, is the triangular tract included by the Wabash and White rivers 
near their confluence. (See map.) <A very large part of this territory is 
below extreme high-water level. Much of the southern and southwestern 
portions of Johnson, and a very considerable part of Decker Township, is
