GRASSHOPPER WARBLER. 
81 
This species is found in Sweden and Denmark, in the 
south of Russia and Siberia, in many parts of Fj-ance and 
Italy, and also in Germany, Holland, and some parts of 
Switzerland. It is only to be met with in low, swampy, and 
wet situations; and, as far as our experience goes, it appears 
to prefer standing to running water, as it does not, that 
we are aware of, frequent river-sides, but confines itself en¬ 
tirely to the vicinity of bogs, morasses, and similar situations 
of a wet and springy nature. We have found it on Ditton 
Marsh in Surrey, in a boggy enclosure overrun with long, 
coarse grass ; also in the unenclosed part of Claremont, 
near the black pond, we have heard its cry. On one occasion 
we sought for it during a considerable time in the vicinity 
of this spot, which is eminently calculated to suit the peculiar 
habits of the species. It was on a very hot day, in the 
middle of summer, that we were walking among the fir-covered 
hills of this beautiful district, and enjoying the fresh and 
fragrant perfumes shed by the pine, the larch, and the red fir, 
that chance led us to the edge of one of the bogs, that are 
there interspersed among the hills. While considering in 
what direction we could best cross this morass, for it was 
of the black and quaking sort, which affords no safe footing 
even in summer, we suddenly heard the singular note of this 
little warblei’, proceeding, as it appeared, from a small birch 
tree, so thin in foliage, and so near to us, that its concealment 
in such a place undetected could be hardly possible. We 
examined the tree with the utmost minuteness, and were 
satisfied that the bird did not escape : but could perceive 
nothing. We next traversed the bog across and across in 
pursuit of the note, which appeared to come sometimes from 
one side, and sometimes from the other. We dissected and 
dispersed tufts of grass, which seemed to conceal the little 
ventriloquist, but in vain. Still the note rung upon our ears 
at intervals, sometimes appearing near, and sometimes dis-
