And so up to fifteen, when the stave was concluded with a shrill “Spell, oh!” and the gang relieved, streaming with perspiration. When the saltpetre was well mashed, they rolled ton water-butts on it, till the floor was like a billiard table. A fleet of chop boats then began to arrive, so many per day, with the tea-chests. Mr. Grey proceeded to lay the first tier on his saltpetre floor, and then built the chests, tier upon tier, beginning at the sides, and leaving in the middle a lane somewhat narrower than a tea-chest Then he applied a screw jack to the chests on both sides, and so enlarged his central aperture, and forced the remaining tea-chests in; and behold the enormous cargo packed as tight as ever shopkeeper packed a box--nineteen thousand eight hundred and six chests, sixty half chests, fifty quarter chests. While Mr. Grey was contemplating his work with singular satisfaction, a small boat from Canton came alongside, and Mr. Tickell, midshipman, ran up the side, skipped on the quarterdeck, saluted it first, and then the first mate; and gave him a line from the captain, desiring him to take the ship down to Second Bar--for her water--at the turn of the tide. Two hours after receipt of this order the ship swung to the ebb. Instantly Mr. Sharpe unmoored, and the _Agra_ began her famous voyage, with her head at right angles to her course; for the wind being foul, all Sharpe could do was to set his topsails, driver, and jib, and keep her in the tide way, and clear of the numerous craft, by backing or filling as the case required; which he did with considerable dexterity, making the sails steer the helm for the nonce: he crossed the Bar at sunset, and brought to with the best bower anchor in five fathoms and a half. Here they began to take in their water, and on the fifth day the six-oared gig was ordered up to Canton for the captain. The next afternoon he passed the ship in her, going down the river to Lin-Tin, to board the Chinese admiral for his chop, or permission to leave China. All night the _Agra_ showed three lights at her mizen peak for him, and kept a sharp look out. But he did not come: he was having a very serious talk with the Chinese admiral; at daybreak, however, the gig was reported in sight: Sharpe told one of the midshipmen to call the boatswain and man the side. Soon the gig ran alongside; two of the ship's boys jumped like monkeys over the bulwarks, lighting, one on the main channels, the other on the midship port, and put the side ropes assiduously in the captain's hands; he bestowed a slight paternal smile on them, the first the imps had ever received from an officer, and went lightly up the sides. The moment his foot touched the deck, the boatswain gave a frightful shrill whistle; the men at the sides uncovered; the captain saluted the quarter-deck, and all the officers saluted him, which he returned, and stepping for a moment to the weather side of his deck, gave the loud command, “All hands heave anchor.” He
