travelling in Marocco, and before the necessity for a consider- 

 able correction to the readings of Secri^tan's aneroid had become 

 apparent. The difference arising from this and other correc- 

 tions applicable to the highest points reached by lis is con- 

 siderable, and requires a deduction of about 500 feet from the 

 estimated height of the Tagherot pass, and about the same from 

 the calculated altitude of Djebel Tezah. The corresponding 

 error in the calculated altitudes for the low country stations, 

 e.g. those between Mogador and Marocco, averages about 

 200 feet.

APPENDIX B. 



Itineraries of Routes from the City of Marocco through the Great 

 Atlas. 



The information respecting the routes here given was supplied 

 by a Jew named Salomon ben Daoud, an inhabitant of the city 

 of Marocco engaged in trading operations with the natives of 

 the portions of the Great Atlas wherein the authority of the 

 Sultan is recognised. In the absence of more accurate reports, 

 it appears desirable to publish this slight contribution to the 

 topography of a country altogether unknown to Europeans, 

 excepting so far as we were able to visit a few of the places 

 enumerated. To assist those who may hereafter seek to follow 

 any of these routes, the names of places inserted in the French 

 map of Marocco by Captain. Beaudouin, or in the map annexed 

 to this volume, are distinguished by an asterisk. The distances 

 are reckoned by hours, one of which may be counted as equi- 

 valent to four miles in the plain, and to a somewhat lesser 

 distance in the mountain. A day's journey usually varies from 

 eight to ten hours. The spelling of the names is made to agree 

 with that adopted throughout this work, the vowels having the 

 same sounds as in most European languages, and not those 

 peculiar to our country.
