their perception, outrun by the shower, shaken by the light, denied by
the shadow, eluded by the distance, makes the lingering picture that is
all our art. One of the most constant causes of all the mystery and
beauty of that art is surely not that we see by flashes, but that nature
flashes on our meditative eyes. There is no need for the impressionist
to make haste, nor would haste avail him, for mobile nature doubles upon
him, and plays with his delays the exquisite game of visibility.

Momently visible in a shower, invisible within the earth, the
ministration of water is so manifest in the coming rain-cloud that the
husbandman is allowed to see the rain of his own land, yet unclaimed in
the arms of the rainy wind. It is an eager lien that he binds the shower
withal, and the grasp of his anxiety is on the coming cloud. His sense
of property takes aim and reckons distance and speed, and even as he
shoots a little ahead of the equally uncertain ground-game, he knows
approximately how to hit the cloud of his possession. So much is the
rain bound to the earth that, unable to compel it, man has yet found a
way, by lying in wait, to put his price upon it. The exhaustible cloud
"outweeps its rain," and only the inexhaustible sun seems to repeat and
to enforce his cumulative fires upon every span of ground, innumerable.
The rain is wasted upon the sea, but only by a fantasy can the sun's
waste be made a reproach to the ocean, the desert, or the sealed-up

unfruitfully.

Baby of the cloud, rain is carried long enough within that troubled
breast to make all the multitude of days unlike each other. Rain, as the
end of the cloud, divides light and withholds it; in its flight warning
away the sun, and in its final fall dismissing shadow. It is a threat
and a reconciliation; it removes mountains compared with which the Alps
