The Green Lakes, of which there are several in the 
county, are also noted far and wide. ‘The bottom of those 
at Manlius goes down gradually for several yards, and 
then suddenly breaks off, going straight down to a maxi- 
mum depth of 180 feet. Their color is a beautiful green, 
especially so in the bright sunshine, while the water is so 
clear that trees and rocks lying at considerable depths can 
be clearly and distinctly seen. These trunks of trees, 
branches, etc., have for many years excited the curiosity 
of all beholders, for the persons living in that vicinity 
positively assert that they have occupied these same posi- 
tions from the time that the early settlers first saw them. 
Furthermore, these logs absolutely refuse to decay. An 
investigation will prove that these stories contain more 
truth than one might at first suppose. For, besides the 
fact that these lakes contain quite a strong solution of sul- 
phur, they also deposit marl, which slowly but surely cov- 
ers and encrusts everything that falls into them, and in 
this way the form of the substance is preserved. Green 
Lake, west of Jamesville, differs from those in Manlius, 
not only in the fact that its color is much darker, more 
dismal looking and awe inspiring, but also in the fact that 
it is almost completely surrounded by bold and precipitous 
walls of limestone, which rise up 200 feet above the sur- 
face of the water. Hence, should we happen to see the 
place for the first time while alone, and also on a dark fore- 
boding day, we could not but be impressed by the ex- 
treme stillness of the place, while a single glance down 
the steep banks and into the dark green water below 
would fill our hearts with the remarkable feelings, first, 
of awe and of fear, then of grandeur and sublimity at this 
wonderful manifestation of the Creator’s power in nature. 
These lakes have long furnished sources for conjecture, 
but it seems probable that at some time or other the water 
contained in them was on a level with the surrounding
