The leafing goes on now rapidly, these warm and moist showery days.

May 14.

P. M. — To Hill by boat. 

A St. Domingo cuckoo, black-billed with red round eye, a silent, long, slender, graceful bird, dark cinnamon (?) above, pure white beneath. It is in a leisurely manner picking the young caterpillars out of a nest (now about a third of an inch long) with its long, curved bill. Not timid. 

Black willows have begun to leaf, — if they are such in front of Monroe's. 

White ash and common elm began to leaf yesterday, if I have not named the elm before. The former will apparently open to-morrow. 

The black ash, i. e. that by the river, may have been open a day or two. 

Apple in bloom.

Swamp white oak perhaps will open to-morrow.

Celtis has begun to leaf. 

I think I may say that the white oak leaves have now fallen; saw but one or two small trees with them day before yesterday. 

Sumach began to leaf, say yesterday. 

Pear opened, say the 12th. 

The leafing goes on now rapidly, these warm and moist showery days.
