"Look in the hollow of the stone beneath you, silly Nial!" came the child's voice mockingly.
Nial stared; then, descrying nothing, leaped into the hollow. The next moment he recoiled with a look of horror.
An adder lay in a little ferny crevice at the base of the rock. Its writhing black body was trying to get out of sight, but could not. An adder was the one thing in nature that the outcast could not bear to look at. It gave him a horror, that at times moved him to frenzy, at times made him flee as a man accursed.
Now he stood as one fascinated. If the nàthair had wriggled toward him he would have stood motionless.
With a heavy swaying motion of his head he muttered:
"Anam nathrach, Anam nathrach!"[7]
But when the adder saw a crevice elsewhere, that promised better, and swiftly wriggled to it, Nial saw that it was only a crawling beast, this and nothing more.
With a dart like a hawk he seized it by the tail, swung it round his head while he shouted, "Droch spadadh ort! Droch spadadh ort! Bad death to you! Bad death to you!" and flung it against the face of the rock, so that when it fell across a bracken it lay as though stunned or dead.
A shout of elfish laughter came from Oona, who had sprung from her covert, and watched Nial's discomfiture with malicious glee. He turned slowly. His corrugated brows were knitted grotesquely, as with dull bewildered eyes he stared in the direction of the laughter. With a furtive motion he kept shifting his weight now to one foot, now to another, occasionally dragging one backward as though pawing the ground. His tormentor knew well these signs of perplexity, and her light tantalizing glee rippled afresh across the glade. She stood knee-deep in bracken, with her right hand clasping the black-and-silver bough of a birk: a golden-green hue upon her from beneath from the sunlit fern; upon her from above a flood of yellow sunshine, so that she stood out like a human flower, a new daffodil of the woods.
The wild, rude, misshapen creature who fronted her seemed less human now than his wont, with that bovine stare, that uncouth guise, his over-large and heavy head slowly swaying, his restless stamping and scraping. Suddenly it dawned upon him that Oona had not been in earnest: that she had played with, and now mocked him. His eyes grew red, as those of wild swine do of a sudden, or as those of an angry badger. A spray of froth blew from his hanging lip. His long horny fingers opened and closed like sheathing and unsheathing claws.
