Lake Umbagog.
Aquatic Insects.
1907
August 12.
  A still, warm, cloudy morning.
Crossing the widest part of the lower
Lake (ie opposite Lakeside) I
find it dimpled everywhere, even
in the very middle, by the ceaseless
movements of innumerable water
spiders or skaters as they are
called. They look smaller than
those we have near Cambridge and
seem lighter and more active of
movement. As I sit watching them
from my canoe a breeze from
the S.W. reaches the Lake &
ruffles the surface (?) every
movement. This at once sends the
skaters shoreward. They hurry past
me like frightened sheep and now
all are gone most of them to windward.
Like the lucky bugs (which I do not
see this morning although they are
common in the Lake) they are timid 
boatmen after all. I find them floating
in great rafts in shore behind rocks
& drift wood when the wind
blows strong.
