Station no. 5, that of the scrub oaks, gave 15.52 cc. daily for 
18 months, and 15.30 cc. daily for the period from January to May 
1913. For the summer (June to November) the average was 
13-95 cc. daily, corresponding to the short-leaved pine and the 
pastured beech wood. The winter rate was 14.1 cc., intermediate 
between that of the oaks and pine. The period of greatest evapora- 
tion was April; while December, January, and February showed

about the same minimum. The actual minimum was 7.39 Cc. 
in late December, and the actual maximum 27.97 cc. in early May. 
This forest, therefore, does not show such wide variation for the 
seasons as do the others given, and the curve representing the 
years’ averages runs more evenly for this forest than does that of 
any other except the flatwoods. This evenness may be related 
to the fact that, although the trees are deciduous, their leaves, 
after dying and turning brown, remain on the branches most of
