As they shot past the _Susan_ the boys waved their hands to Master Lirriper, who, after coming down in the morning and receiving their letters for their parents, had returned at once to the city and had taken his place on board the _Susan_, so as to be able to tell their father that he had seen the last of them. The distance between London Bridge and Deptford was traversed in a very short time. A vessel with her flags flying and her canvas already loosened was hanging to a buoy some distance out in the stream, and as the boat came near enough for the captain to distinguish those on board, the mooring-rope was slipped, the head sails flattened in, and the vessel began to swing round. Before her head was down stream the boat was alongside. The two officers followed by the boys ascended the ladder by the side. The luggage was quickly handed up, and the servitors followed. The sails were sheeted home, and the vessel began to move rapidly through the water. The boys had thought the _Susan_ an imposing craft, but they were surprised, indeed, at the space on board the _Dover Castle_. In the stern there was a lofty poop with spacious cabins. Six guns were ranged along on each side of the deck, and when the sails were got up they seemed so vast to the boys that they felt a sense of littleness on board the great craft. They had been relieved to find that Captain Vere had his own servitor with him; for in talking it over they had mutually expressed their doubt as to their ability to render such service as Captain Vere would be accustomed to. The wind was from the south-west, and the vessel was off Sheerness before the tide turned. There was, however, no occasion to anchor, for the wind was strong enough to take them against the flood. During the voyage they had no duties to perform. The ship's cook prepared the meals, and the officers' servants waited on them, the lads taking their meals with the two officers. Their destination was Bergen-op-Zoom, a town at the mouth of the Scheldt, of the garrison of which the companies of both Francis Vere and Captain Allen formed part. As soon as the low coasts of Holland came in sight the boys watched them with the most lively interest. "We are passing Sluys now," Captain Vere said. "The land almost ahead of us is Walcheren; and that spire belongs to Flushing. We could go outside and up the channel between the island and Beveland, and then up the Eastern Scheldt to Bergen-op-Zoom; but instead of that we shall follow the western channel, which is more direct." "It is as flat as our Essex coast," Geoffrey remarked.
