of the bushes and swarmed up a thick trunk of a huge tree to hide himself therein; and he sat upon a branch whence he could descry everything beneath him whilst none below could catch a glimpse of him above; and that tree grew close beside a rock which towered high above-head. The horsemen, young, active, and doughty riders, came close up to the rock-face and all dismounted; whereat Ali Baba took good note of them and soon he was fully persuaded by their mien and demeanour that they were a troop of highwaymen who, having fallen upon a caravan had despoiled it and carried off the spoil and brought their booty to this place with intent of concealing it safely in some cache. Moreover he observed that they were forty in number.——And as the morn began to dawn Shahrazad held her peace till The end of the Six Hundred and Twenty-sixth Night. Then said she:——I have heard, O auspicious king, that Ali Baba saw the robbers, as soon as they came under the tree, each unbridle his horse and hobble it; then all took off their saddle-bags which proved to be full of gold and silver. The man who seemed to be the captain presently pushed forwards, load on shoulder, through thorns and thickets, till he came up to a certain spot where he uttered these strange words, “Open, O Simsim!”[40] and forthwith appeared a wide doorway in the face of the rock.

Ali Baba remained still perched on the tree and watched their departure; nor would he descend until what time they were clean gone out of sight, lest perchance one of them return and look around and descry him. Then he thought within himself, “I too will try the virtue of those magical words and see if at my bidding the door will open and close.” So he called out aloud, “Open, O Simsim!” And no sooner had he spoken than straightway the portal flew open and he entered within. He saw a large cavern and a vaulted, in height equalling the stature of a full-grown man and it was hewn in the live stone and lighted up with light that came through air-holes and bullseyes in the upper surface of the rock which formed the roof. He had expected to find naught save outer gloom
