each other, until some of them get broad-leaved and succulent, and
you have a coarse vegetable tapestry which Raphael would not have
disdained to spread over the foreground of his masterpiece. The
Professor pretends that he found such a one in Charles Street,
which, in its dare-devil impudence of rough-and-tumble vegetation,
beat the pretty-behaved flower-beds of the Public Garden as
ignominiously as a group of young tatterdemalions playing
pitch-and-toss beats a row of Sunday-school-boys with their
teacher at their head.

But then the Professor has one of his burrows in that region, and
puts everything in high colors relating to it. That is his way
about everything. I hold any man cheap,--he said,--of whom nothing
stronger can be uttered than that all his geese are swans.--How is
that, Professor?--said I;--I should have set you down for one of
that sort.--Sir,--said he,--I am proud to say, that Nature has so
far enriched me, that I cannot own so much as a duck without seeing
in it as pretty a swan as ever swam the basin in the garden of the
Luxembourg. And the Professor showed the whites of his eyes
devoutly, like one returning thanks after a dinner of many courses.

I don't know anything sweeter than this leaking in of Nature
through all the cracks in the walls and floors of cities. You heap
up a million tons of hewn rocks on a square mile or two of earth
which was green once. The trees look down from the hill-sides and
ask each other, as they stand on tiptoe,--"What are these people
about?" And the small herbs at their feet look up and whisper
back,--"We will go and see." So the small herbs pack themselves up
in the least possible bundles, and wait until the wind steals to
them at night and whispers, "Come with me." Then they go softly
with it into the great city,--one to a cleft in the pavement, one
to a spout on the roof, one to a seam in the marbles over a rich
gentleman's bones, and one to the grave without a stone where
nothing but a man is buried,--and there they grow, looking down on
the generations of men from mouldy roofs, looking up from between
the less-trodden pavements, looking out through iron cemetery-
railings. Listen to them, when there is only a light breath
stirring, and you will hear them saying to each other,--"Wait
awhile!" The words run along the telegraph of those narrow green
lines that border the roads leading from the city, until they reach
the slope of the hills, and the tr
