This struck Rob very strongly as he stopped at last peering round the bole of a huge tree. He was about thirty yards from the lizard now, and in a position which commanded its side as it stood gazing straight before it at some object, bird or insect, in front.

It was just the position for resting the bow-arm against the tree for steadiness of aim, and feeling that he could do no better, but doubtful of his skill and quite as doubtful of the likelihood of the wooden arrow-head piercing the glistening skin of the iguana, Rob took a careful aim, as he drew his arrow to his ear in good old archer style, and let his missile fly.

Roughly made, unfeathered, and sent by a tyro, it was no wonder that it flew far wide of the mark, striking a bough away to the left and then dropping from twig to twig till it reached the undergrowth below.

Where it struck was some distance from the lizard, and the sound and the falling of the reed gave it the idea that the danger point was there, so that it directed its attention in that quarter, stood very erect, and swelled itself out fiercely.

This gave Rob ample time to fit another arrow to his string, correct his aim, and loosen the shaft after drawing it to the head. This one whizzed by the iguana, making it flinch slightly; but treating it as if it had been a bird which had suddenly flashed by, the lizard fixed its eyes on the spot where this second arrow struck.

“I shall never hit the thing,” thought Rob as he fitted another arrow and corrected his aim still more, but this time too much, for the arrow flew off to the lizard’s right.

“Three arrows gone!” muttered the lad as he prepared for another try, took a long aim, and, to his great delight, saw the missile strike the bough just below where the iguana stood, but only for it to make a rush forward out of his sight.

“But I should have hit it if I had only aimed a little higher,” he thought.

The lizard being invisible, he was about to return to Shaddy, thinking of his companion’s disappointment, when, to his surprise, he suddenly saw the reptile reappear upon a lower branch, where it stood watchful and eager, and once more presenting a splendid opportunity for a skilled archer.

“It’s of no good,” thought Rob. “I must practise every day at a mark,” and once more taking aim without exercising much care, but more with an idea of satisfying his companion if he were watching his actions than of hitting his mark, he drew the arrow quickly to the head, gave one glance along the slight reed at the iguana, the bow-string twanged, and the next moment the reptile was gone.
