Lake Umbagog.
1909. 
June 16 [June 16, 1909]
  Clear with strong W. wind through day and light S. E. breeze 
at evening. Early morning cool & bracing. Middle of day very warm. 
  Most of the forest trees except the black ash are now in 
nearly or quite full leaf. Lilacs are just coming in to blossom. 
The blossoms of the Apple and Rhodora are fading and many 
of the petals have fallen. [?] cherry still in flower. Dwarf cornel 
nearly at its best. Its blossoms form belts of snowy whiteness 
along the borders of the wood paths & around openings in the woods. 
The Canada Elder is out of flower. Buttercups in full blossom.
A few dandelion blossoms still showing in the fields & pastures. 
Wild strawberry just [at] its prime. 
Vegetation.
  The nuptial concerts of the Common Toad are fast waning 
but I hear their trilling in a few places about the lake 
this evening. Its waters already swarm with their tiny black 
tadpoles. Bullfrogs bellowing and every direction after sunset. 
They are almost as numerous this season as they were thirty 
odd years ago. Green Frogs are about equally common but 
not in full cry as yet. I hear no Fowler's Toads & doubt 
if they occur here. 
Batrachians.
  I have seen a few Ephemera daily ever since my 
arrival but they have not been numerous previous to yesterday 
when I noted them by scores. This evening the air over 
the lake, even in the middle of the flooded meadows, was
 swarming with them. They did not dip in the water 
at all but soared & hovered and drifted about 6 to 10 feet
above it. My canoe sail was literally covered with them 
at times. All seemed to be of one kind a small, dark-colored 
that I do not see in summer or autumn.
