The Admiralty lent the entire crews for the three destroyers and skeleton crews for the two cruisers, consisting of petty officers, seamen gunners, engine-room artificers, armourers, and also a small detachment of marines, whilst, acting on the advice of the Foreign Office and the Chinese Embassy, both of which threw out hints of the possibility of treachery, the remainder of the crews were taken exclusively from Naval Reserve men of known good character. During the following three weeks several suspicious incidents occurred which suggested that influences were at work to retard or damage the expedition. Thorneycroft’s destroyer broke down on two occasions. On the second trial the finding of a loose nut in the high-pressure cylinder whilst the engines were being preliminarily turned, averted a terrible catastrophe. It was highly probable that it had been placed there intentionally. Laird’s cruiser developed several small break-downs, attributed to improperly fastened locking nuts, whilst the main bearings of one of her screw shafts became almost red-hot, and it was found that sand had been mixed with the water that was pumped over it during the full speed trial. This alone delayed the departure of the expedition for a month, as the huge casting had to be removed. Laird’s destroyer was also run down one night by a tug-boat whilst lying anchored off Birkenhead, and as it was a perfectly clear night, and she was not in the usual course of tugs, this was very suspicious. Fortunately the damage was not serious. Most serious of all was the discovery of a man, dressed as a dockyard labourer, tampering with the magazine locks of Armstrong’s cruiser, with many yards of fuse and a dynamite cartridge in his pocket, which naturally he could not account for. However, three months after the receipt of Ping Sang’s letter, Armstrong’s cruiser, named by Helston the _Strong Arm_, the three destroyers "No. 1", "No. 2", and "No. 3", and a stout little merchant steamer, the _Sylvia_, to be used as store-ship, were lying at Spithead, gaily flying the Yellow Dragon at their ensign staffs, and only awaiting the completion of the repairs to Laird’s ship, which Helston named the _Laird_. Helston, the Doctor, and two or three officers were still remaining in London completing the work of fitting out the squadron. *CHAPTER IV* *The Pirates are not Idle* A Disaster—"The Mysterious Three"—Suspicions Confirmed—Three Chinamen—Helston Desperate One night after dinner, whilst they were playing billiards, the folding doors were flung open and Hopkins, whom Helston had not seen since he had first met him on his way to Newcastle, rushed in, nearly upsetting the waiter.
