Flying at night was colder than flying by day, but it was more thrilling, too. They whistled through an immense blackness. Stars glittered overhead, and quicksilver patches of moonlight and shadow flashed across the clouds below. They were going to Ireland, but why, David did not know. The Phoenix was playing its wait-and-see game again. In an hour or so they shot out over the edge of the cloud mass, and David could see a rocky coast below, dark and cold in the half-light. The Phoenix began to slant down toward it, and presently they landed in a little meadow. One side of the meadow ran down to a bog filled with reeds, and on the other side was a gloomy wood. Everything was dark and indistinct, but David thought he could tell why the Phoenix had called this the Emerald Isle. The grass beneath their feet was the thickest he had ever felt. He touched a boulder and found it furry with moss. With the wood and the reed-choked bog, the whole place would be rich with various greens in the daylight. Just then they saw a little man approaching them from the wood. He was three feet tall, dressed all in green, and had a long white beard. When he reached them he raised his cap politely and said, "Good evenin' to you." "A fine evening to you, my good Leprechaun," said the Phoenix. "Could you kindly tell us--" "Will you have a cigar?" the Leprechaun interrupted. With a surprised "Thank you very much," the Phoenix took the cigar, bit off the end, and popped it into its beak. The Leprechaun lighted it, and the Phoenix puffed away. "Stick o' gum, lad?" said the Leprechaun to David, holding out a pack. "Why, yes, thank you," said David. He took the stick of gum from the pack, and was immediately sorry for it. The stick was made of wood and had a small wire spring, like a mouse trap, which snapped down on his finger and made him yelp with pain. At the same instant the Phoenix's cigar exploded, knocking the startled bird backwards into a bush. "Haw haw haw!" shouted the Leprechaun, rolling on the ground and holding his sides. "Haw haw haw!" In a trice the Phoenix had pounced on the Leprechaun and pinned him to the ground. "Let him up," said David furiously. "I'll punch his head for him." "I think, my boy," said the Phoenix coldly, "that I shall carry the creature up into the clouds and drop him. Or should we take him back with us and hand him over to the Scientist?" "Now, don't take offense, Your Honor," said the Leprechaun. "I thought you'd look at it as kind o' comic." "Exceedingly comic," said the Phoenix severely. "I am quite overcome with mirth and merriment. But perhaps--_perhaps_--I shall let you off lightly if you tell us where the Banshee lives." "The--the Banshee of Mare's Nest Wood?" "The same. Speak!" A new light of respect and fear came into the Leprechaun's eyes. "She's a terror, she is. What'll you be wanting--" "None of your business!" roared the Phoenix. "Where is she?"
