As they sat on the bank, they were sideways to the three men watching them only a few feet above.

'Let's rush them!' whispered Hoole suddenly.

He seized Flanso's spear, pushed his revolver into Trentham's hand, and before the latter could utter a word, either in assent or in remonstrance, the American was half-way down the slope. Trentham had no choice but to back him up, and he dashed after his friend with scarcely a moment's delay.

The Germans heard the sound of Hoole's movements through the bush, turned their heads and sprang up. One of them raised his revolver to fire, but Hoole, now only three or four yards away, launched his spear. His sudden action flurried the German's aim, his shot flew wide, and the next moment he fell back, cursing, and tearing the spear from his shoulder. His companion, seeing Trentham rushing at him with levelled revolver, hesitated a moment, and caught sight of Flanso swooping down immediately behind the Englishman.

ONE OF THE GERMANS RAISED HIS REVOLVER, BUT BEFORE HE COULD FIRE, HOOLE LAUNCHED THE SPEAR AT HIM.

'Hands up!' cried Trentham, taking advantage of the man's momentary hesitation.

Up went his hands.

'Guess we 'll borrow your revolvers, gentlemen,' said Hoole, picking up the weapon dropped by the wounded man. Trentham took the other man's from his belt. 'Keep your eye on them, Trentham,' Hoole went on, 'while I kind of size up this machine of theirs.'

Trentham and Flanso stood guard over the Germans while the unwounded man bathed his comrade's arm and bound up his wound. Meanwhile Hoole examined the seaplane in a manner that took Trentham by surprise. There was a sureness, a purposefulness about him; he seemed to know exactly what he was looking for. Indeed, he pulled the engine about, as Trentham afterwards told him, as if he were its maker. A very few minutes' inspection sufficed to make him wise, as he put it.
