nigra, Liquidamber styraciflua, Acer rubrum tridens, and Nyssa 
sylvatica biflora. The undershrubs were Quercus myrtifolia, Q. 
minima, Pyrus arbutifolia, Rubus villosus, Rhus copallina, Ilex 
glabra, I. lucida, Hypericum fasciculatum, Vaccinium virgaium 
tenellum, Viburnum nudum, and V. molle. A common liana was 
Gelsemium sempervirens, but the most common plant of all was 
Serenoa serrulata (saw palmetto). The herbs about this station 
make a distinctive list, the majority being species of Compositae, 
as Helianthus angustifolius, Rudbeckia laciniata, Aster Tradescantt, 
Solidago fistulosa, and Bidens bipinnata; there were also Polygala 
lutea, Viola lanceolata, Sabatia gracilis, S. lanceolata, Pinguicula 
lutea, and Valerianella radiata. 
Stations no. 8 and no. g were located in October 1913 in the 
meadow of the Ocklocknee River. One was placed in a willow 
growth on the south bank, the apparatus being located in the outer 
border of the narrow strip of trees edging the stream and 5 or 6 ft. 
above the water at its normal stages. At this point a strip of bare 
sand, 15-20 ft. wide, separated the willows from a birch zone. 
Immediately bordering the river this meadow strip was about one- 
fifth of a mile wide, bounded on the east by a strip of Norfolk Sand 
with the long-leaved pines. The area occupied by the willows was 
subject to frequent overflow and no other plants seemed able to 
maintain themselves permanently in this zone. The growth here 
was not luxuriant, few of the trees exceeding a height of 10 or 12 ft. 
The records from these stations were interrupted by frost about 
December 21, 1913, and again on January 18, 1914, while from 
February 1 to March 28.the apparatus was covered by water tw0- 
thirds of the time and no records were secured. The birch station, 
4 ft. higher and 15~20 ft. farther inland than the willow station, 
suffered similar interruption, except that the interval due to the 
flood was two weeks shorter and the apparatus was reestablished 
March 15, at which time the willow station was still completely 
under water. On the whole, the growth here was more luxuriant, 
although few of the trees had trunk diameters greater than 6 
inches, or height greater than 15-20 ft. 
Laboratory examination of each of the soils at the several 
stations was made to determine the organic content and general
