I could not avoid a good hearty laugh at this quaint story of a phenomenal fall of the mercury in a barometer; for it was easy to conjure up a picture of the rapidly growing alarm and dismay of the captain as he watched the steady and speedy shrinkage of the metallic column, and of the feverish anxiety and haste with which he would proceed with his preparations to meet the swoop of the supposedly approaching typhoon, as also of his disgust at the discovery that all his alarm and anxiety had been brought about by the unsuspected leakage of a leather bag! But the story served as a hint to me; what had happened once might happen again; and I forthwith retired to the cabin and carefully examined our own instrument to discover whether, haply, such an accident had occurred in our case. But no, the bag into which the base of the glass tube was plunged was perfectly sound and intact; and, meanwhile, during my brief colloquy with Tasker a further fall of a full tenth had occurred. I lost no time in returning to the deck. "The scare is quite genuine this time, Mr Tasker," I said; "there is no leakage in our mercury bag to account for the heavy drop; moreover, the drop has increased by a full tenth. Therefore, although the present aspect of the weather may not be precisely alarming, we will proceed to snug down at once, if you please, in view of the fact that the crew we carry is not precisely what might be called efficient, and will probably take an unconscionably long time over the work." "Ay, ay, sir," answered Tasker. "I expect the mercury ain't droppin' exactly for nothin', therefore, as you says, we'd better be makin' ready for what's in store for us." Then, facing forward, he gave the order: "Clew up your royal and t'garns'l, furl 'em, and then get the yards down on deck. Hurry, you scallywags; the more work you does now, the more time for play will you have a'ter breakfast." The "snugging down" process occupied us until nearly four bells of the forenoon watch; but when at length it was completed we felt that we were prepared to face anything, our royal and topgallant-mast and all our yards being down on deck, the fore and main-topmasts and the jib-boom housed, the great mainsail snugly stowed and the heavy boom securely supported in a strong crutch, and the ship under fore and main storm staysails only.
