This affidavit with five others was laid before the customs officers, but the evidence was adjudged to be insufficient to warrant the detention of the vessel. Determined not to neglect any possible chance of stopping the "290" from getting to sea, the energetic United States minister placed copies of the affidavits before an eminent English lawyer, Mr. R. P. Collier, who arrived at a very different conclusion in regard to them. He said: "It appears difficult to make out a stronger case of infringement of the foreign enlistment act, which, if not enforced on this occasion, is little better than a dead letter." Armed with this opinion, Mr. Adams lost no time in laying it before Lord Russell, together with the affidavits upon which it was based. His success was an agreeable surprise. An official opinion was at last obtained to the effect that the "290" might lawfully be detained, and an order was issued in accordance therewith. The Confederate agents were well aware of the efforts of Mr. Adams and his assistants, and suspected the nature of the errand of the Tuscarora. Friends of the builders and others were invited to participate in a trial trip of "No. 290" on July 29th. Her armament was not yet on board. The still unfinished deck was decorated with flags, and occupied by a gay party of pleasure seekers, including a number of ladies, and several British custom house officials. The vessel dropped down the Mersey, and the revellers partook of luncheon in the cabin. Then a tug steamed alongside, and the surprised guests were requested to step on board. Bunting and luncheon were hastily hustled out of the way, and holiday ease instantly gave way to the work of getting to sea. Anchor was dropped in Moelfre Bay on the coast of Wales, and preparations for a voyage were rapidly pushed forward. A tug brought out about twenty-five more men, and the crew signed shipping articles for Nassau. At two o'clock on the morning of July 31st "No. 290" turned her prow toward the Irish sea. On the same morning came the British officials with the order for her detention. Information of the proposed seizure had leaked out through the medium of Confederate spies, and the bird had flown. Meanwhile the Federal agents had discovered the location of "No. 290" at Moelfre Bay, and the Tuscarora proceeded to Queenstown and thence up St. George's Channel in quest of her. Mr. Adams telegraphed Captain Craven: At latest yesterday she was off Point Lynas; you must catch her if you can, and, if necessary, follow her across the Atlantic. But the fleeing steamer passed through the North Channel, around the north coast of Ireland and vanished in the broad ocean. The Tuscarora at once abandoned the chase. CHAPTER III.
