My whole you will probably pass.

300. Entire, I belong to the United States; remove one eye, and I belong to a horse; curtail me, and I belong to the human race; curtail again, and I am the child’s best friend; curtail again, and I am best known to the printer; curtail again, and I become invisible.

301.

Though for years I had lived, I was unknown to fame,

Till I rescued a slave, and I gave him my name.

Though then Abolitionist—still I enthrall,

And unless I imprison—of no use at all.

’Tis strange I should be both a boon and a blow,
