eplied Jack; "perhaps they can speak if they
liked--probably they have an idiom of their own. You, that know all
languages, and a great many more besides, possibly can converse with
them."

"I should like to know," said Becker, "why you two gentlemen are
always snarling at each other; it is neither amusing nor amiable."

"Ernest is continually showing me up, father, and it is but fair that
I should be allowed to retort now and then. But to return to plants,
Ernest; you say they have nerves?"

"If they have," said Willis, "they do not seem to possess the bottle
of salts that most nervous ladies usually have."

"No," replied Ernest, "they have no nerves, properly so called; but
there are plants, and I may add many plants, which, by their
qualities--I may almost say by their intelligence--seem to be placed
much higher in the scale of creation than they really are. The
sensitive plant, for example, shrinks when it is touched; tulips open
their petals when the weather is fine, and shut them again at sunset
or when it rains; wild barley, when placed on a table, often moves by
itself, especially when it has been first warmed by the hand; the
heliotrope always turns the face of its flowers to the sun."

"A still more singular instance of this kind was recently discovered
in Carolina," remarked Becker; "it is called the _fly-trap_. Its round
leaves secrete a sugary fluid, and are covered with a number of ridges
which are extremely irritable: whenever a fly touches the surface the
leaf immediately folds inwards, contracts, and continues this process
till its victim is either pierced with its spines or stifled by the
pressure."

"It is probably a Corsican plant," observed Jack, "whose ancestors
have had a misunderstanding with the brotherhood of flies, and have
left the _Vendetta_ as a legacy to their descendants."

"There is nothing in Nature," continued Ernest, "so obstinate as a
plant. Let us take one, for example, at its birth, that is, to-day, at
the age when animals modify or acquire their instincts, and you will
find that your own will must yield to that of the plant."

"If you mean to say that the plant will refuse to play on the flute or
learn to dance, were I to wish it to do so, I am entirely of your
opinion."

"No, but suppose you were to plant it upside down, with the plantule
above and the radicle below; do you think it would grow that way?"

"Plantule and radicle are ambitious words, my dear brother; rec
