But every second brought also the scout nearer to the hanging nest. Up, up he went, now straddling some bending limb, now swinging himself with lightning agility to one above. Once, crawling on a horizontal branch, he slid over and hung beneath it, like an opossum.

Twisting and wriggling his way out of this predicament, he scrambled on, handing himself from branch to branch, and once losing his foothold and hanging by one hand.

Tom Slade watched spellbound, as the agile form ascended, using every physical device and disregarding every danger. More than once Tom almost shuddered at the chances which his young companion took upon some perilously slender limb. Once, the impulse seized him to call a warning, but he refrained from a kind of inspired confidence in that young dare-devil who by now seemed a mere speck of brown moving in and out of the darkened green above him. Once he was on the point of shouting advice to Hervey about what to do in the unlikely event of his reaching the nest before the eagle, or in the more serious contingency of an encounter with that armed warrior.

For, thrilled as he was at the young scout’s agility and fine abandon, he was yet doubtful of Hervey’s power of deliberation and presence of mind. But no one could advise a creature capable of being carried away in a very frenzy of nervous enthusiasm, and Tom, sober and sensible, knew this. Hervey Willetts would do this thing or crash his brains out, one or the other, and no one could help or hinder him.

Amid the crackling sound of breaking limbs and a shower of leaves and smaller twigs, the mighty bird of prey, extricating himself from every obstacle, tore his way into the leafy recess where his little victim waited, trembling. Every branch seemed agitated by his ruthless, irresistible advance, and the hanging nest swayed upon its slender branch, as the cruel talons of the intruder fixed themselves in the yielding bark. The weight of the monster bird upon the very branch which his little victim had chosen for a home caused it to bend almost to the breaking point, and the hanging nest, agitated by the shock, swung low near the end of the curving bough.

HERVEY SAVES THE LITTLE BIRD FROM THE EAGLE.

That was bad strategy on the part of the invader. As the end of the bough descended under his weight, there was the appalling sound of a splitting branch, which made Tom Slade’s blood run cold, and he held his breath in frightful suspense, expecting to see the form of his young friend come crashing to earth.

But the boy who had ventured out so far upon that straining branch had swung free of it just in time, and was swinging from the branch above. The great bird had played into the hands of his dexterous enemy when he had placed his weight upon the branch above, from which the nest hung.

Hervey could not have trusted his own weight upon that upper branch, and he knew it. But even had he dared to do this he could not have passed the enraged bird who stood guard within a yard or two of his little victim. When the weight of the bird’s great body bent the branch down, Hervey, close in toward the trunk just below, saw his chance. He did not see the danger.
