Nut shell

Definition and stakes

Portrait of Eleanor Stackhouse Atkinson Eleanor Stackhouse Atkinson,  The How and Why Library — Section III (1915)

“ How did the nuts get their hard shells, and their tough or prickly or mossy husks and cups? Just as the apple got its rosy skin, its sweet pulp and its horn-lined seed nests. The shell of a nut is like the seed nest of the apple. It is the hardened covering of the baby egg in the blossom. The cup or husk of the acorn, is really the twig on which the blossom grew. A plant can grow stem and root and bark and leaf and flower, all so very different. So it isn't hard to take a twig bud and turn it into a thorn on the rose, or a tendril on the grape vine, or a cup or husk on a nut tree. ”

Jason Elmer Hammond,  Suggestive programs for special day exercises… (1898)

“ This stolid old chap is a hard nut to crack.
Butternut—
Old Mr. Butternut, just from Brazil,
Is rugged and rough as the side of a hill.
But like many a countenance quite as ill-favored.
He covers a kernel deliciously flavored.
All—
Now, dearest schoolmates, I'm sure we have told
All the queer rhymes that nut-shell can hold.

“ This kernel then dries as you see here, but when the nut falls on favourable soil, the germ within the kernel swells until it bursts through the shell, and, taking root, springs up a new tree.'
`I do not understand,' said Fritz, `how the little germ manages to get through this great thick shell, which is not like an almond or hazel-nut shell, that is divided down the middle already.'
`Nature provides for all things,' I answered, taking up the pieces. `Look here, do you see these three round holes near the stalk; it is through them that the germ obtains egress.
