character. The Orangeburg Fine Sandy Loam soil from the 
Spanish oak-post oak station, when dried, was a dark brownish 
gray. It is an excellent soil, rich in humus, and the drainage in the 
locality of the station was good. The soil from the short-leaved pine 
station was a medium brownish gray, similar to the preceding but 
containing a larger proportion of sand (Orangeburg Sand), and less 
humus. The soil from the beech wood was the same according to 
the classification of the United States Soil Survey Report, and it 
resembled that of the pine wood in the samples taken in the course 
of this study, but both soil and subsoil were of a brighter reddish 
tinge. The area of the beech station was hardly so well drained as 
that of the pine wood. The soil from the Pinus palustris forest on 
Norfolk Sand was very similar in color (both soil and subsoil) to 
that of the short-leaved pine, but contained decidedly less clay, 
separating in loose grains when dry, while the other dried in small 
lumps. It was also less rich in humus. The drainage was excellent 
to excessive. The soil from the scrub oak forest (which adjoined 
the preceding on the south) was very similar to Norfolk Sand in 
texture but a brighter red and perceptibly poorer in humus. The 
soil from the Leon Sand station was a medium gray sand with a 
very small admixture of organic materials. It was too wet for 
agricultural crops. 
The evaporation records from the mesophytic forest (station 
no. 1), during the time it was steadily running, showed a consistently 
lower average and actual rate than any other station. The 
minimum monthly rate for this station was 6.05 cc. per day in 
January. The actual minimum was 4.5 cc. in January. The 
maximum monthly rate was 10.27 cc. daily in April, and the actual 
maximum was 11.9 cc. the first of May. The mean average rate 
for the 4 months covering the time from the minimum to the maxi- 
mum was 8.5 cc. per day, an interesting result in comparison 
with the record of evaporation for beech-maple forests in the 
north. 
Station no. 2, the Spanish oak-post oak forest, in comparison, 
gave a record of 9.90 cc. per day for the same period of the same 
year. The average of this station for 18 months’ continuous and 
unbroken record, however, is 14 cc. daily. The minimum monthly
