1917] GANO & MCNEILL—EVAPORATION RECORDS 321 
Station no 4. At this station the evaporimeter was broken by 
frost once in the second winter of its history, on January 11; it 
was shot to pieces once; and was once in the immediate path of a 
June cyclone which blew down most of the trees in a track 800 ft. 
wide. By this storm the cup was demolished but the reservoir 
was unbroken. The location was then changed a few rods to the 
east. This station was peculiar in that the trees were essentially 
like those of the Leon Sand station (no. 7) near Lake Jackson, and 
the herbaceous plants like those on the sandhill soil. At the outer 
border of this soil, where the Norfolk Sand and the sandhill join, 
the scrub oaks gave way abruptly, the line between the two soils 
being generally as sharp as if the planting had been artificial. 
e Leon Sand station, no. 7, was in operation more or less 
continuously for 18 months, being broken by frost once the first 
winter and twice during the second winter; it was also once in the 
path of a fire. This Leon Sand is situated 9 miles northwest of 
Tallahassee, being a strip of long-leaved pine forest about 200 yards 
wide. This small area is bordered on the north by a slough which 
is directly bordered by Norfolk Sand, and to the south the soil is 
the Norfolk Fine Sand, each with characteristic vegetation. This 
strip of the Leon Sand is an outlying neck of a larger area of the 
same soil 2.5 miles wide and 1 mile long, the only area of this 
particular soil in the northern part. of the county which is accessible 
to the railroad. However, in its growth it is typical of the larger 
area of the flatwoods to the southeast. This soil, wherever it 
occurs, is very level and poorly drained and therefore excessively 
wet a large part of the year. Station no. 7, therefore, was on the 
wettest soil of any, and its vegetation should be compared with that 
of station no. 6, which also supported a long-leaved pine forest on 
the Norfolk Sand, one of the driest soils of the region. The wood on 
the Leon Sand was very open and the destruction caused by turpen- 
tining had still further thinned it. Owing partly to frequent fires 
and partly to the general quality of the soil and the drainage, the 
undershrubs were very low, seldom exceeding 2 ft. in height. The 
forest floor was sparsely covered with wire grasses. Apart from 
the pines, the trees noted about this station were occasional small 
specimens of deciduous trees, as Quercus falcata, Q. virginiana, Q.
