“He shall carry our knapsacks. Later we will tie him to a tree, and if he is lucky someone will find him in the morning.”

Their preparations were soon made; Rex was the last to leave the foundry which he had come so many thousand miles to search for the jewels of the Shulimoffs. It was with the greatest reluctance even now that he tore himself away.

In single file they crossed the garden; Simon put up a better performance than they had hoped with the rough crutches that they had made for him, but their progress was slow. It took them over an hour to reach the death-dealing fence.

They decided that it was better to allow the camp to settle down for the night before making their attempt. Simon lay stretched out on his furs in a little hollow they had found — the journey had tired him sorely. Rex spent a considerable time searching for a tall sapling that would bear his weight. At last he found one to his liking and made several practice jumps, sailing high into the air. They divided their last tin of sardines and a packet of stale biscuits. Rakov was tied securely to a tree, and at last they decided that it was time to start.

Rex took De Richleau in his strong arms, and lifted him clear above his head. With a great heave he pitched him feet-foremost over the deadly fence — four feet clear of the wire.

The Duke smothered a cry of pain as he landed partly on his bad shoulder, but he was soon standing ready on the other side; the rugs and knapsacks were then passed over.

Marie Lou was easy. To Rex she was like a baby, and he dropped her gently in De Richleau’s arms.

Simon was lifted over with the greatest precautions — to throw him was to risk injuring his leg. De Richleau, being so much shorter than Rex, the business was not accomplished without difficulty, and Simon passed some apprehensive moments while he was within a few inches of the wire — but they got him safely to the other side.

“Stand clear,” Rex warned them, and with a rush his big body hurtled through the air; he dropped his pole neatly as he sprang, and cleared the fence by a yard at least.

Together they crept forward the two hundred yards to the edge of the trees. A row of hangars stood, a dark bulk, no great distance away. They crouched in a small runnel while Rex gave his last instructions.
