Honest Captain Cuttle, as the weeks flew over him in his fortified retreat, by no means abated any of his prudent provisions against surprise, because of the non-appearance of the enemy. The Captain argued that his present security was too profound and wonderful to endure much longer; he knew that when the wind stood in a fair quarter, the weathercock was seldom nailed there; and he was too well acquainted with the determined and dauntless character of Mrs MacStinger, to doubt that that heroic woman had devoted herself to the task of his discovery and capture. Trembling beneath the weight of these reasons, Captain Cuttle lived a very close and retired life; seldom stirring abroad until after dark; venturing even then only into the obscurest streets; never going forth at all on Sundays; and both within and without the walls of his retreat, avoiding bonnets, as if they were worn by raging lions.
The Captain never dreamed that in the event of his being pounced upon by Mrs MacStinger, in his walks, it would be possible to offer resistance. He felt that it could not be done. He saw himself, in his mind's eye, put meekly in a hackney-coach, and carried off to his old lodgings. He foresaw that, once immured there, he was a lost man: his hat gone; Mrs MacStinger watchful of him day and night; reproaches heaped upon his head, before the infant family; himself the guilty object of suspicion and distrust; an ogre in the children's eyes, and in their mother's a detected traitor.
A violent perspiration, and a lowness of spirits, always came over the Captain as this gloomy picture presented itself to his imagination. It generally did so previous to his stealing out of doors at night for air and exercise. Sensible of the risk he ran, the Captain took leave of Rob, at those times, with the solemnity which became a man who might never return: exhorting him, in the event of his (the Captain's) being lost sight of, for a time, to tread in the paths of virtue, and keep the brazen instruments well polished.
But not to throw away a chance; and to secure to himself a means, in case of the worst, of holding communication with the external world; Captain Cuttle soon conceived the happy idea of teaching Rob the Grinder some secret signal, by which that adherent might make his presence and fidelity known to his commander, in the hour of adversity. After much cogitation, the Captain decided in favour of instructing him to whistle the marine melody, 'Oh cheerily, cheerily!' and Rob the Grinder attaining a point as near perfection in that accomplishment as a landsman could hope to reach, the Captain impressed these mysterious instructions on his mind:
'Now, my lad, stand by! If ever I'm took - '
'Took, Captain!' interposed Rob, with his round eyes wide open.
'Ah!' said Captain Cuttle darkly, 'if ever I goes away, meaning to come back to supper, and don't come within hail again, twenty-four hours arter my loss, go you to Brig Place and whistle that 'ere tune near my old moorings - not as if you was a meaning of it, you understand, but as if you'd drifted there, promiscuous. If I answer in that tune, you sheer off, my lad, and come back four-and-twenty hours arterwards; if I answer in another tune, do you stand off and on, and wait till I throw out further signals. Do you understand them orders, now?'
'What am I to stand off and on of, Captain?' inquired Rob. 'The horse-road?'
