 the lake is bordered by the luittou bush (Cephalanthns occidentalis), osier 

 dogwood (Coi'nus stolonifera). Rosa Carolina. Ccvttonwood (I'opnlus luoiii-

 This succession of societies is carried a stej) further on the west shore 

 of the lake southwest of Yarnelle's landing. In addition to the foregoing 

 are swamp white oak MJuercus bit olori. silver maple (Acer dasyearpuni). 



Fig. 2. \'iew acrciss lake from Yarnelle's landing. The basin effect is more apparent 

 here. The transition in vegetative types is very rapid at this point, owing to the somewhat 

 abrupt rise in the topograi)hy. It quickly passes from hydrophytie through the marsh stage 

 to mesophytic. On the shore, zones of the button bush and osier dogwood are followed by 

 those of Carolina rose, willow and, lastly, elm. The coming of this tree means permanent 

 conditions looking to the mesophytic types. 



.and sycamore iPlatanus occidentalis). The land adjoining this on the 

 west, which is slightly elevated and better drained, and which might

 So we must look toward the south where the hand of man has not 

 interfered with the work of nature. Here, as we might expect, in the 

 same relation as to position, that is a step further from the lake, higher, 

 drier, and well drained, we tind the hazel (Corylus Americana), the grape, 

 Mayapple (Podophyllum peltatum). Catnip (Nepeta Cataria), Smilacina
