The Hunting of the Snark he delights to tell."" The poem was printed in "The Hunting of the Snark" with permission from Chataway's mother. Included with many copies of the first edition of "The Hunting of the Snark" was Carroll's three-page, religious tract to his young readers, "An Easter Greeting to Every Child Who Loves "Alice"".

Gardner suggests that Carroll included the tract as a way of balancing the dark tone of the poem.
