Seventh of Henry Holiday's original ilustrations to "The Hunting of the Snark" by Lewis Carroll.

From Fit the Fifth: The Beaver's Lesson. The Butcher and Beaver hear the song of the Jubjub bird, and this causes the Butcher to be reminded of his childhood, and begin a lengthy lesson to he Beaver. Afterwards, they become friends. As for the strange creatures:

The Beaver brought paper, portfolio, pens,

    And ink in unfailing supplies:

While strange creepy creatures came out of their dens,

    And watched them with wondering eyes.

 

So engrossed was the Butcher, the heeded them not,

    As he wrote with a pen in each hand,

And explained all the while in a popular style

    Which the Beaver could well understand.
