Lake Umbagog.
1907.
literally riddled with holes. All these could not well be
examined and even long experience in this particular kind of
field work failed to enable its possessor to distinguish
certainly between such as would repay investigation and
such as might safely by passed by. Indeed he was sure to
waste much valuable time in climbing to promising looking
but untenanted cavities and equally so to commit, every now
and then, the still graver mistake of neglecting others of
unpromising appearance which, as he might afterwards learn
to his sorrow, had contained rare or coveted eggs. Or again
he might find, upon breaking into and thereby ruining a
nest from which a bird has been seen to fly, that he was
either too early or too late for a full set of fresh eggs.
These and similar difficulties and disappointments only added,
of course, to the pleasure and interest of a day spent
about the shores of Lake Umbagog looking for the eggs of
stub nesting birds. And its material rewards in the way 
of specimens secured, if not perhaps equal to those which
have been attained in other and still more favoured regions,
were, nevertheless, often very satisfactory.

  The water among the stubs was anywhere from two
or three to six or eight feet deep in spring. Hence our
work was always done in boats - the pleasantest of all
methods of collecting - and usually with the assistance of
one of the local guides. While engaged in it we often
disturbed Bats which were spending the day in hollow trunks
or under loose scales of bark. An experience which I had
with them on June 18 was so very unusual and 
interesting that I am tempted to describe it here.
