On entering the little ravine of Camp Run it seemed as if we were in
a new land, for since the last time we had been there a great change
had taken place.  At that time not a leaf was on a tree, to-day
they were covered with them.  The change was so great that we experienced 
a little trouble to find our way.  Our red marks, too, we
found, could not be seen.  Below our camp on Camp Run I
found Solea concolor -- a field of it -- hundreds of plants.  After
crossing the brook to see the Tipularia, which also could not be
found, all traces of it having disappeared we started, homeward
by way of Owl Camp and the open field.  We reached the cars
about 8 o'clock and were home by 9 P.M.  One nest with little
birds was observed as we entered the ravine.  It would have escaped 
my attention entirely had not the mother bird flown off as we
passed.
