The weather was remarkably fine. For some time previous, the atmos 
phere was cloudy, with some rain, and the prospects were very discourag- 
ing ; yet only an hour or two before the eclipse came on, the clouds broke 
away, and presented a sky as clear and serene as could possibly be de- 
sired. Indeed, we were great gainers by the previous state of the atmos- 
phere, the-sky being washed clean of all, vapors, while yet the sun had 
not shone.long enough to disturb the tranquillity of iha:eedinm, by as- 
cending and descending currents. Hence, there was a r_shatp- 
hess in the line presented by the solar disk. _ ae
