Tracy: ROUGHING IT TO THE YOSEMITE 113 
of rock at the foot of the Yosemite Falls. Four years 
ago I gathered a few at this place, and this year I found 
even less growing there, so I left them, just noting that 
they were there. Prof. Hall, in Flora of the Yosemite, 
speaks of collecting this fern in this same place. 
One trip, which lost us twe days of time and which > 
resulted in a disappointment, was our journey to Lake 
Tenaya. It was a disappointment in that I expected 
more than we realized, and in that we were driven out 
by those “demons” of the high mountain regions, the _ 
mosquitoes. I think we might have stood them, but the 
horses could not protect themselves and were nearly 
crazed. One horse was white when traveling in other 
places but in the Lake region she became very dark — 
gray, so completely covered was she by the mosquitoes. 
_ Upon this trip we reached our highest altitude, ae 
_ ft., and just on one side of this point was growing ee 
-luxuriantly Cryptogramma acrostichoides, and with it one 
_ Filix fragilis. No other fern of interest was seen on this 
trip unless it was Pellaea ornithopus-W rightiana. I run 
these two names together, for I certainly saw almost 2 ae 
every stage intermediate berwe the pes 98 both, see oe
