‘and avenues of an ancient and ruined city. Hence the name by 
which the place is known:—“ Rock City.” Here, in sheltered spots, 
the snow and ice sometimes remain all the year long. And here 
Epigea repens, Ilex monticola, Listera cordata, the two Clintontas, 
and other plants delighting in a cool and moist atmosphere, luxuriate. 
The lake shore, on either side, affords plants well recognized as 
maritime :—as, for example, Cakile Americana, Lathyrus martitimus, 
Euphorbia polygontfolia, and Triplasis purpurea. Hudsonia tomentosa, 
attributed to the shores of the great lakes, has not yet been seen. 
But with the others grow some plants, not known to inhabit the sea- 
coast, and not met with inland; such as Artemisia Canadensis, Gly 
cyrrhiza lepidota and Corispermum hyssopifolium. With us, Ptelea 
trifoliata, and Juniperus communts are always lake-shore plants; and 
Lithospermum hirtum is rarely met with elsewhere. 
The atmosphere at the Falls of Niagara is charged, in an extraor- 
dinary degree, with moisture. Thespray of the cataract, descending 
in some places in an incessant shower, ‘produces a fitting habitat for 
several species of plants, elsewhere, rarely, if ever, seen within our lim- 
its. Aypericum Kalmianum, Parnassta Caroliniana, Lobelia Kalmit, 
Campanula rotundifolia, Utricularia cornuta, Gentiana crinita, Carex 
(deri, etc., here find congenial environment. At Portage, similar 
conditions sustain several of the same species, and beside them 
Saxifraga aizotdes, Primula Mistassinica and Pinguicula vulgarts. 
In the gorge of both rivers, Pterospora Andromedea is found. 
At Point Abino, on the Canadian shore of Lake Erie, at the dis- 
tance of eleven miles from Buffalo, the sand of the beach has been 
drifted by the winds into dunes, sometimes a hundred feet in height, 
covered with trees of ancient growth. We have not met, in any 
other place, with Corydalis flavula, Sisymbrium Thaliana, the rose- 
colored Arabis Drummond, nor, of late years, the most fragrant of 
our native plants, Joneses uniflora. UHere, too, in the crevices of 
the corniferous limestone, lying but a little above the surface of the 
lake and kept constantly wet by its waters, Linum striatum is 
found, growing in abundance :—its only locality known in our 
vicinity. Near it occurs a form of Mypericum Kalmianum, with 
smaller corymbs, but larger flowers, than it produces at the Falls. 
In the immediate vicinity of Buffalo only small patches of 
sphagnous bogs are found. But at the distance of ten or fifteen
