In my lists for Oklahoma and Arkansas, not a Stereodon appears and only 
one Polytrichum. That is probably my fault and not the fault of the localities 
visited, but certainly neither genus is as common as in the northeastern states, 
and we, who do most of our collecting in New England, miss them both as only 
old and constant friends can be missed. 
A little transgression before my list: the red-bud or Judas tree made the 
thickets along the river beds a blaze of color, and the flowering dogwoods were 
scattered through the woods in all their beauty. Of the birds, three were of 
special interest: the tufted titmouse, the road-runner or chaparral-bird, and the 
scissor-tailed fly catcher, the latter being exquisitely colored and the most grace- 
ful bird imaginable. The geology of the region is at once the despair and the 
delight of its students. There is a great deal of limestone which ought to mean 
more limestone mosses than I collected.
