Concord.- up into parties of from fifty to one hundred birds
each and seeking other resting places. As on the 15th
there were Barn and Bank Swallows flying about over
this roost but I saw none actually alight there.

  The Eave Swallow feeds its young on wing the two birds
meeting in the air and rising straight upward six
or eight feet face to face until the bills finally come
together one or both uttering the tcha note rapidly the
while. I saw this to-night shortly after sunset when
the two birds engaged were fully 300 ft. above the
earth.

  Where do the Bank Swallows take their young? The
large colony on Dalkin's Hill is dwindling fast
yet the number of birds which frequent the river
meadows is also decreasing and I have not as yet
seen a single young bird. Of course it is possible
that no young have been reared in this bank but
most of the holes have certainly not been molested
by man.

  As I was sailing down river this afternoon a
Bittern rose from the pickerel weed on the
margin of the water uttering, as it flew off, a series
of short, hoarse croaks (ŏc - ŏc - ŏc or ӑc - ӑc - ӑc).

  The pickerel weed (Pondenteria[sic: should be Pontederia]) is by far the most
beautiful flowering plant along the borders of this
river. where almost everywhere it forms a broad
border between the belt of lily pads and the meadow grass.
