CH. VII. MAEOCCO CARPETS. 153 



Our regret at not having been able to accompany 

 Maw on this excursion was much increased when towards 

 evening he returned with a number of interesting plants, 

 several of which proved to be additions to the ]Marocco 

 flora. The most notable of these was an undescribed 

 species of the tropical and subtropical genus Boorhavia, 

 and a curious Reseda, seemingly distinct from any de- 

 scribed species. Besides these, he had gathered a variety 

 of Forskahlea tenacisaima described by the late Mr. 

 Webb as F. Cossoniana, Andropogon lanir/er, a fine 

 grass whose leaves have the scent of Verbena, Echinojps 

 strigosus, and one or two more species characteristic of 

 the flora of Southern Algeria. 



Maw also visited some of the bazaars, and described 

 them as miserable and repulsive, and we preferred to 

 let the carpet merchant who had been recommended to 

 us bring his goods to our quarters. The carpets made 

 here are not considered equal to those of Eabat, but they 

 are comparatively cheap and durable. On inquiring how 

 our purchases could be forwarded to Mogador, we found 

 that the hire of a camel with his driver for this weary 

 four or fi\'e days' joiu-ney amounted only to about seven 

 shillings of our money, and that the risk of robbery was 

 considered too trifling to be worth mentioning. 



The comparison of five observations, taken on as many 

 successive days, gives for the altitude of our station in 

 Marocco a height of 511*9 metres, or 1,679 English feet. 

 Allowing for the difference of level, the height of the 

 great square may be taken to be very closely 500 metres 

 or 1,640 English feet. The observations were calculated 

 on the assumption that the barometer at sea level at 

 Mogador stood at 760 millimetres, and hence it is not 

 surprising that the results of each day's observation vary 

 form the mean, in some cases as much as fifty feet ; but, as 

 settled weather prevailed at this period, the mean adopted 

 is probably very near the truth. ]\Iost of the results of 

 our observations (see Appendix) agree well with the few
