  Besides the Snipe and Sora I heard many other
 interesting, if common birds, while floating in my canoe
this evening at the mouth of Beaver Dam Lagoon.
While the daylight still held there were Red-wings
and Swamp Sparrows singing far & near and a Wood
Thrush chanting at the base of Holden's Hill. A King bird
mounted skyward and went through its trembling song flight.
As twilight deepened the Bitterns (two of them) "pumped"
a few times. Then a Whippoorwill began in the
woods on the southern edge of the meadows. A Greater
Yellow-legs & a Spotted Sandpiper were wandering through
the marshes, calling at short intervals. Hylas were 
peeping by thousands all about me. These are the
river meadow ones who hold high carnival after those
in inland pools have become silent or nearly so. I heard three
Bull Frogs trump. Four Musk rats in sight at once, all swimming.
