The Fabulous Roc.
The roc, the huge bird that gave Sindbad the sailor his ride through the air, is not to be compared with some of those mentioned in the Talmud. Some mariners saw one of those large birds standing up to the lower joint of the leg in a river, and thinking the water could not be deep, they were hastening to bathe, when a voice from heaven said: "Step not in there; seven years ago a carpenter dropped his axe there, and it hath not yet reached the bottom."
