The European name of Mogador, is supposed to be derived from Mugdul, or Modogul, a Moorish Saiut. The Governor of Mogador told me to go to look at his slaves, and see that they were well fed and well clothed. But every rich man's horses and dogs are well-fed and well-housed. Mr. Davidson did not visit Morocco as an abolitionist. Head what impression this Maroquine slavery made upon his mind.
