"A Spectre has first choice, by right,
In filling up a vacancy;
Then Phantom, Goblin, Elf, and Sprite -
If all these fail them, they invite
The nicest Ghoul that they can see.
[...]
"My father was a Brownie, Sir;
My mother was a Fairy.
The notion had occurred to her,
The children would be happier,
If they were taught to vary.
"The notion soon became a craze;
And, when it once began, she
Brought us all out in different ways -
One was a Pixy, two were Fays,
Another was a Banshee;
"The Fetch and Kelpie went to school
And gave a lot of trouble;
Next came a Poltergeist and Ghoul,
And then two Trolls (which broke the rule),
A Goblin, and a Double -
"(If that's a snuff-box on the shelf,"
He added with a yawn,
"I'll take a pinch) - next came an Elf,
And then a Phantom (that's myself),
And last, a Leprechaun.
