198 Remarks on the Site of Troy 
veloped with trees ; the air over it is conse- 
quently highly charged with moisture, and 
the vapour from the spring will be condensed, 
and become visible much sooner than if the 
surrounding atmosphere were dry. 
The water of the cold spring, on the con- 
trary, being distilled from many crevices into 
a large reservoir, is actually of a lower tem- 
perature than the sources by which it is fed, 
and than the water in the other reservoir. In 
addition to this, as it lies in an open and ex- 
posed situation, the surrounding atmosphere 
is dry, and consequently the vapour from this 
reservoir, even had it been of the same tem- 
perature, which it is not, as the other, would 
neither so soon become visible, nor ever be 
so dense. In cold weather the real difference 
of temperature between the water of the two 
reservoirs will be much increased, for whilst 
that in the small one, or warm spring, will 
always retain its primitive heat, that in the 
large one, or cold spring, may be cooled 
down to almost any degree. 
But it is unnecessary to say more on this 
point, for whatever causes induce a belief 
now, that these springs are, one warm and 
the other cold, would be equally able to pro- 
duce a similar belief in the age of Homer ; 
and the business of the poet being widely
