ace a quarter of a mile off; for they
furrow the water slightly, making a conspicuous ripple bounded by two
diverging lines, but the skaters glide over it without rippling it
perceptibly. When the surface is considerably agitated there are no
skaters nor water-bugs on it, but apparently, in calm days, they leave
their havens and adventurously glide forth from the shore by short
impulses till they completely cover it. It is a soothing employment,
on one of those fine days in the fall when all the warmth of the sun
is fully appreciated, to sit on a stump on such a height as this,
overlooking the pond, and study the dimpling circles which are
incessantly inscribed on its otherwise invisible surface amid the
reflected skies and trees. Over this great expanse there is no
disturbance but it is thus at once gently smoothed away and assuaged,
as, when a vase of water is jarred, the trembling circles seek the shore
and all is smooth again. Not a fish can leap or an insect fall on the
pond but it is thus reported in circling dimples, in lines of beauty, as
it were the constant welling up of its fountain, the gentle pulsing of
its life, the heaving of its breast. The thrills of joy and thrills
of pain are undistinguishable. How peaceful the phenomena of the lake!
Again the works of man shine as in the spring. Ay, every leaf and twig
and stone and cobweb sparkles now at mid-afternoon as when covered with
dew in a spring morning. Every motion of an oar or an insect produces a
flash of light; and if an oar falls, how sweet the echo!

In such a day, in September or October, Walden is a perfect forest
mirror, set round with stones as precious to my eye as if fewer or
rarer. Nothing so fair, so pure, and at the same time so large, as a
lake, perchance, lies on the surface of the earth. Sky water. It needs
no fence. Nations come and go without defiling it. It is a mirror which
no stone can crack, whose quicksilver will never wear off, whose gilding
Nature continually repairs; no storms, no dust, can dim its surface ever
fresh;--a mirror in which all impurity presented to it sinks, swept and
dusted by the sun's hazy brush--this the light dust-cloth--which retains
no breath that is breathed on it, but sends its own to float as clouds
high above its surface, and be reflected in its bosom still.

A field of water betrays the spirit that is in the air. It is
continually receiving new life and motion from above. It is intermediate
in its natu
