184 DISTRICT OF TROAS. 
CHAP, reached these, we found, in front of them, a 
beautiful natural bason, six or eight feet deep, 
serving as a reservoir for the water in the first 
moments of its emission, and before its fall. 
It was so clear, that the minutest object might 
be discerned at the bottom. The copious over- 
flowing of this reservoir causes the appearance, 
to a spectator below, of different cascades, 
falling to the depth of about forty feet; but 
there is only one source. Behind are the chasms 
whence the water issues. We passed through 
one of these into a cavern. Here the water 
appeared rushing with great force beneath the 
rock, towards the bason on the outside. It was 
the coldest spring we had found in the country; 
the mercury in the thermometer falling, in 
two minutes, to 34", according to the scale 
of Fahrenheit. When placed in the reservoir 
immediately above the fall, where the water 
was more exposed to the atmosphere, its tem- 
perature was three degrees higher. The whole 
rock about the source is covered with moss. 
Close to the bason grew hazel and plane trees ; 
above were oaks and pines ; all beyond was a 
naked and tremendous precipice '. 
(l) Upon GaroarDs we found a beautiful new species, both of 
Crocus, and of Anemone. The first we have called Crocus caiididus, 
and the second Anemone j'ormosu. They may be thus described :
