that it breeds in the higher mountainous districts 
of this state, as do many other of our spring visitaB** 
that regularly pass a week or two with us in the lo"'*'? 
parts, and then retire to the mountains and inla®*^ 
forests to breed. 
But Pennsylvania is not the favourite resort of 
species. The cane brakes, swamps, river shores, 
deep watery solitudes of Louisiana, Tennesee, and 
Mississippi territory, possess them in abundance ; thf* 
they are eminently distinguished by the loudness, sWf®.*' 
ness, and espressive vivacity of their notes, which beSf'" 
very high and clear, falling with .an .almost irapercept'^' 
gTiidiition till they are scarcely articulated. At thf^ 
times the musician is perched on the middle br.anch^ 
of a ti’ce over the brook or river bank, pouring B j 
his charming melody, that may be distinctly he«S 
for nearly half a mile. The voice of this little h'** 
appeared to me so exquisitely sweet .and express!^ 
that I was never tired of listening to it, while traversi”: 
the deep shaded hollows of those cane brakes where '' 
usually resorts. I have never vet met with its nest. 
The water thrush is six incKcs long, and nine ai'^ * 
half in extent ; the whole upper parts are of a uuifo''''! 
and very dark olive, with a line of white extending 
the eye, and .along the sides of the neck ; the 
parts are white, tinged with yellow ochre ; the whB* 
breast and sides are marked with pointed spots ^ 
stre.al£s of black or deep brown ; bill, dusky bro"''*: 
legs, flesh coloured,- tail, nearly even; bill, forn**’., 
almost exactly like the golden-crowned thrush j''! 
described ; and except in frequenting the water, wbL 
resembling it in manners. Male and fem.ale 
alike.
