[April 18, 1896]

  I heard the first really full chorus of Hylas to-night
- in the little meadow by the landing but to my
surprise there were but few Leopard Frogs or Toads calling
anywhere. I suspect that they have literally worn
themselves out by their unceasing efforts during the
last two days & nights. But perhaps the weather
conditions this evening may have had something
to do with their comparative silence.
  Swamp Sparrows were trilling everywhere along the
river after sunset. There were also a good many
Robins singing. Indeed I fancy that the summer
quota of the latter birds is now about full.
