NEW ESCAPEMENT. 



Interior of 

 Africa. 



they were often in the habit. of going. I have there spent one 

 day with them, and declared that I meant to proceed for Tan- 

 gier. They will accompany me to a certain distance, and give 

 out at Mogadore that I am on my way to Tangier. As soon as 

 I am left alone with my fellow-traveller, I mean to clothe 

 myself in my Moorish garb, and to enter the great road which 

 leads from Tafilet to Morocco. From thence I shall reach 

 Deminit, a town situated at the foot of Mount Atlas, where 

 I shall be safe from any searches which the governor of Moga- 

 dore might make, should he learn that I have not gone to 

 Tangier. At Deminit, I shall join a caravan, which will pass 

 there about that time, and with it I shall cross Mount Atlas, 

 covered with snow, and next enter the burning plains of Tafilet. 

 I shall remain at Tafilet with a German renegado. There are 

 in that city a number of Germans. There are some Germans 

 in Morocco, and to one of them I am indebted for some valua- 

 ble information. I expect to find a German in Tombuctoo, 

 and there I mean to remain six months, making it the centre of 

 my observations on the interior of Africa. I shall pass for a 

 physician : I have laid in a supply of medicines, of which I 

 know the application. It is my wish to penetrate towards the 

 south, and to be able to reach Wesemb, or the Cape. Should 

 I find this too difficult, I mean to return to Europe to publish 

 the journal of my travels ; and shall again return to Africa, 

 where I am destined to make some discoveries.'
