"Very well," said Mr. Crawshay. "I shall expect you to lunch. We'll talk over things then more at leisure."

While Warrender went off to do the necessary shopping, Armstrong and Pratt, in the dinghy, set out for their new camping-place. It lay on the shore of a little natural bay some fifteen yards deep and about half that width. Mr. Crawshay's gardeners had already mown the long grass and lopped some of the lower branches of overhanging trees. A ten minutes' walk through the wood and across fields brought the two boys to the house, where Mr. Crawshay had already arrived. Having seen that none of his men were about, the old gentleman led them to the outhouse in which he kept his pram; and by the time that Warrender, conveying his purchases in the motor-boat, reached the new encampment, the others had carried the odd little craft across the fields, and found a secure hiding-place for it in the wood a little distance from the bay, almost opposite to the north end of the island, near a spot convenient for landing under cover of the trees. With it Mr. Crawshay had lent them a couple of light oars.

After erecting their new tent--a sorry specimen compared with the one that had been destroyed--they went up to the house for lunch, discussed their plans with Mr. Crawshay privately in his study, and returned to fence the camp with barbed wire and get things in order. So far there had been no sign of the enemy; but in the course of the afternoon Armstrong climbed a tree from which, unobserved himself, he could obtain a view of the opposite bank of the river, and discovered without surprise that a spy was lurking among the bushes. No doubt all their ostensible proceedings had been watched, and they congratulated themselves on the illusion of mere defensiveness which their business-like activity must have created.

During the remainder of the day they were careful not to depart from their usual procedure. They had an early supper; when they had cleared away and washed up, they placed three oddly assorted and shabby deck-chairs, purchased from Blevins, in front of the tent, and while Armstrong and Warrender read newspapers, Pratt warbled sentimental ditties to the accompaniment of his banjo.

Just before dark Pratt and Armstrong went into the tent to go to bed, while Warrender perambulated the camp armed with a thick club. The spin of a coin had decided that he should remain on guard while the others paid a nocturnal visit to the island.

About midnight, when it was quite dark, the two raiders crept out of the tent, and striking inland for a little, made their roundabout way to the spot where the pram was hidden. Reconnoitring carefully, to assure themselves that their movements had not been followed, they lifted the pram, lowered it gently into the water, and pushed off, floating on the tide near the bank, and steering with one oar in the stern. They struck the shore of the island about midway, seized a projecting branch, and drawing their craft into the bank, pulled it up among the reeds at the edge. Then they started to cross the island.

It was pitch-dark in the thicket. Spreading roots and trailing brambles tripped their feet; their faces were lashed by the foliage as they pushed their way through; thorns caught at their clothes. It was difficult to avoid noise. Twigs snapped underfoot, branches creaked and rustled, and every now and again there was a strident shriek of rent clothing as they tore themselves from the embrace of some clinging bramble. Heedless of the obstacles, hot and weary, they plodded doggedly on, and presently, after making unconscionably slow progress, they emerged upon the bank of the river. The stream looked much wider than they had expected.

"Whereabouts are we?" whispered Pratt.

"We've come too far south, I fancy," returned Armstrong.

They peered up and down, trying vainly to discover some landmark. They stood listening; there was breeze enough to cause the moaning, but they heard no sound except the rustle of the leaves and the gentle gurgle of the tide. They cast about, taking wary steps up stream and down; hoping in one direction or the other to come upon the wilderness garden.
