30 a. Panicum boscii molle (Vasey) Hitche, and Chase. Much 
like P. boscii except not quite so tall and downy pubescent thru- 
out. Hamilton, Lawrence, Cuyahoga. 
31. Panicum chandestinum L. Hispid Panic-grass. An 
erect or ascending rather stout perennial, simple at first but much 
branched later in the season. Sheaths longer than the internodes, 
papillose-hispid, especially the upper ones; leaf-blades 2 to 8 inches 
long, to IJ 4 inches wide, cordate, clasping, glabrous, ciliate at 
the base; primary panicle 3 to .5 inches long, branches ascending, 
often long-exserted, secondary panicles often inclined; spikelets 
I inch long, pubescent, eliptic; outer empty glume § as long 
as the spikelet; the second empty glume 9 nerved. In moist 
thickets. General. 
MEETINGS OF THE BIOLOGICAL CLUB. 
Orton Hall, February 2 , 1914. 
The meeting was called to order at 7:30 by the President, 
Mr. Kostir. The minutes were read and approved. The fol¬ 
lowing were elected to membership: Eric S. Cogan, Fred Perry, 
Gertrude Bartlett, Malon Yoder, Rudolf Pintner and Newton 
T. Miller. 
The first paper of the evening was a review of the thesis on 
the study of “Capillary Movement of Soil Moisture, ” by Malcolm 
Sewell. There are three reasons why a plant may not get suf¬ 
ficient water. First the soil water may be gone, second the 
transpiration may be greater than the absorption and thirdly 
the transpiration may be greater than the capillary action of the 
roots. A plant may draw water from a much larger area than 
that in which the roots are, due to capillary action. Mr. Sewell 
then showed a dozen or more slides showing pictures of his tanks 
in which he grew the com on which he based his conclusions. 
One tank had no concrete bottom. The others had concrete 
bottoms in which he kept the water levels at three and five feet, 
respectively. He found that the best results were obtained in the 
tank without a concrete bottom. 
Prof. Osborn next gave an illustrated talk on his trip to 
Maine. He said that there is little known about Maine and that 
much of the State is unexplored. Much of the timber is wasted 
by poor means of lumbering. The path that he took up Mt. 
Katahden was that of an old avalanche. The trip up was a hard 
one due to the rough out-crop of huge rocks. The purpose of 
his trip was to collect leafhoppers. 
Mr. Reed gave a review of some papers read at the meeting 
of physiologists held in Philadelphia. 
Blanche McAvoy, Secretary.
