a few returned, the greater number breaking up into parties iff 
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 500 feet above the earth. 
Where do the Bank Swallows take their young? The 
large colony on Dakin’s Hill is dwindling fast, yet the 
Bank Swallows er 01 D ird.s 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.

rose irom the pickerel weed on the margin of the water, 
uttering, as it flew off, a series of short, hoarse croaks 
(oc-oc-oc or ac-ac-ac). 
The pickerel weed (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 grassT}
