If they were powerful servants, they were also powerful tyrants. Their valor often reaped a harvest of victories, but their obstinacy again and again imperilled their triumphs. With the increase of their power their self-assurance increased likewise. It was not so much the Sultans and Viziers who commanded them as they who commanded the Sultans and Viziers. And if the rebellious Janissaries hoisted on the Atmeidan a kettle, the signal of revolt, it was always with fear and trembling that the Seraglio asked them what were their demands; and the whole Divan breathed more freely when the answer came that it was gold they wanted, and not blood--the blood of their officers. And when, after the great Feast of Bairam, there was the usual distribution of pilaf, and the dangerous kettles were filled full with this savory mess of rice and sheep's flesh, the Sultan, all trembling, would anxiously watch to see how the majestic Janissaries partook of their pottage. If they devoured it voraciously, that was a sign of their satisfaction; but if they only touched it in a finiking sort of way, then the Sultan would fly into the Seraglio, and lock himself up among the damsels of the harem, for it was now certain that their lordships the Janissaries were displeased, and it was well if their displeasure only expressed itself by reducing a whole quarter or so of the city to ashes. Two Sultans had tried to break in two this dangerous double-edged weapon, which inflicted as many wounds in the heart of the realm as ever it dealt outside; but the Janissaries' magic influence was so interwoven with, so ingrafted in, the mind of the nation that public feeling was on their side, and both rulers perished in the bold attempt. They dragged Sultan Osman forth from the Seraglio, and set him on the back of an ass with his face to its tail, carried him in derision from one end of the town to the other, and then flung him into the fatal Seven Towers, where the Turkish rulers and their relatives are wont to be buried alive and die forgotten. Mahmoud II.'s father, Selim, on the other hand, expired beneath the sword-thrusts of the rebels, and those swords were still sharp and those hands were still strong when the son of the man whom they had slain sat on the throne, and under no other Sultan did the throne tremble so much as under him.
