By degrees he calmed down, ceased breaking the point of his pencil, and used his india-rubber less frequently. Then he took to colour and the brush, and here the tide began to turn in his favour. _Such_ a subject surely never before sat to painter since the world began! He became engrossed in his work. The eyes became intent, the hand steady, the heart regular, the whole man intense, while a tremendous frown and compressed lips told that he "meant business!" Not less intense was the attention of the Moor. Of course we cannot tell what his thoughts were, but it seemed not improbable that his eccentric recklessness in violating all his Mohammedan habits and traditions as to the seclusion of women, by thus exposing Hester to the gaze of a young infidel, had aroused feelings of jealousy and suspicion, which were not natural to his kindly and un-Moorish cast of soul. But while young Foster was employed in the application of his powers to energetic labour, the old Moor was engaged in the devotion of _his_ powers to the consumption of smoke. The natural results followed. While the painter became more and more absorbed, so as to forget all around save his sitter and his work, the Moor became more and more devoted to his hookah, till he forgot all around save the soporific influences of smoke. An almost oppressive silence ensued, broken only by the soft puffing of Ben-Ahmed's lips, and an occasional change in the attitude of the painter. And oh! how earnestly did that painter wish that Ben-Ahmed would retire--even for a minute--to give him a chance of exchanging a word or two with his subject. But the Moor was steady as a rock. Indeed he was too steady, for the curtains of his eyes suddenly fell, and shut in the owlish glare with which he had been regarding the middy. At the same moment a sharp click and clatter sent an electric thrill to the hearts of all. The Moor's mouthpiece had fallen on the marble floor! Ben-Ahmed picked it up and replaced it with severe gravity, yet a faint flicker of red in his cheek, and a very slight air of confusion, showed that even a magnificent Moor objects to be caught napping by his slaves. This incident turned Foster's thoughts into a new channel. If the Moor should again succumb to the demands of nature--or the influence of tobacco--how could he best make use of the opportunity? It was a puzzling question. To speak--in a whisper or otherwise--was not to be thought of. Detection would follow almost certainly. The dumb alphabet would have been splendid, though dangerous, but neither he nor Hester understood it. Signs might do. He would try signs, though he had never tried them before. What then? Did not "Never venture, never win," "Faint heart never won," etcetera, and a host of similar proverbs assure him that a midshipman, of all men, should "never say die."
