"In you get, Trefusis," ordered his companion, in a tone that would brook no refusal.

By dint of hunching his shoulders and bending his knees, Ross managed to get into the basket. The lid was shut, and Jan, assisted by the Sub, lifted the heavy load on to his shoulders.

Jolting over the cobble-stones, the cart proceeded at a rapid pace for nearly a quarter of an hour. Then Jan called to the dogs to stop. The lid was thrown back and Ross told to get out.

He found himself outside a small cottage by the side of a canal. Katje was on her knees washing a bundle of clothes; the operation assisted, with disastrous results to the interned officers' effects, by means of two large stones with which she pounded the saturated garments. Without even turning her head to watch the midshipman's exit from the basket, she proceeded vigorously with her task.

Jan led him into the cottage and pointed to a heap of clothes.

"Put these on you," he said. "I will now go for your friend."

Before the Flight-Sub rejoined him, Ross was rigged out as a Dutch youth, in voluminous trousers, long coat, stock, tall cylindrical hat, green stockings, and wooden shoes. His companion had to look twice before he recognized him.

"Now you come with me to Mynheer Guit," said Jan. "He is a bulb merchant, and lives just outside Ymuiden. You will then go on board a barge that brings the boxes of bulbs from Mynheer Guit's warehouse to the ship. I will be with you. The men in the barge will say nothing. Before to-night you will be safe on board the Hoorn."

Jan was as good as his word. That night the fugitives slept comfortably in the cabin of the mate of the steamship Hoorn; and at tide-time, early on Saturday morning while it was still dark, the vessel glided between the breakwater of Ymuiden, and shaped a course for the mouth of the Thames.
