To Ball's Hill at 9 A. M. paddling down in the open 
canoe. Spent most of the day with Pat cutting down trees 
on the oak knoll near Bensen’s landing. At 4 P. M. started 
for a walk, traversing the woods between Ball's and Davis’s 
Hill, The air was soft and warm and the water over the 
meadows perfectly calm. The sun had just come out and 
Robins, Bluebirds, Song Sparrows and Red-wings were singing 
joyously. A Dove was cooing near the glacial hollow and 
in the pines on the hillside above, a Pine Warbler (the 
first) singing. An Osprey whistled several times in the 
direction of Davis's Hill. Saw two Fox Sparrows with some 
Tree Sparrows but both species were silent. Suddenly, as 
if at a. given signal, a great number of Wood Frogs began 
croaking on the Bedford shore of the river. They are the 
first I have heard and I have heard no Hylas since the 
single individual that piped a few times in Davis's swamp 
on the afternoon of the 1st, 
I started for the Buttricks' at 5.20 and,paddled 
up in forty minutes, crossing the meadows. The water was 
as smooth as glass and the evening delightful. Red-wings 
and Song Sparrows were singing all along the lines of trees 
and bushes. I saw two Wood Ducks flying together near 
Hunt's Pond and two Musk Rats swimming near shore. A King¬ 
fisher near Hunt's landing, rattling. 
There was a marked increase in the number of Robins 
to-day but either they are scarce here this spring or else
