THE RED SEA HILLS 355 



morning good Mahomed Maghazi told me (the camelry 

 not having arrived) that our choice lay between 

 (i) a wash, and (2) coffee for breakfast. Now I must 

 have both . . . and I got them. For, having first 

 splashed my face in the wash-basin, we made coffee 

 with its contents afterwards. My two companions, 

 luckily, still remain unaware of this outrage! Even after 

 boiling, the water was bitter I refer, of course, to 

 unused water. 



Ariel are distinctly migratory and at this period 

 (March- April) were moving northwards ; nor among the 

 thousands seen, 'do I recollect observing any fawns. A 

 corresponding counter-movement occurs in autumn when, 

 after the rains, vast herds of ariel pass southward towards 

 the Atbara and beyond. They are among that class of 

 wild animal that seasonally shift their ground, higher or 

 lower, according to pasturage. Thus hundreds may be 

 seen in a locality which a month later is deserted ; 

 though the abandoned haunt may then be reoccupied 

 by gazelles, which also wander afar, but whose require- 

 ments differ. 



Another predisposing cause for seasonal movements 

 perhaps more potent even than food-supply is a seroot- 

 fly of sorts, which in spring invades the higher grounds 

 in ferocious swarms which drive both game and Arab 

 herdsmen, along with their flocks, pell - mell from the 

 hills. 



If it be permissible to hazard a tentative opinion based 

 solely on such narrow limits as personal observation afford, 

 I would suggest that such animals as ariel, which season- 

 ally shift their pasturage between higher and lower levels, 

 become the more predisposed to extend their migrations, 

 since a mobile habit grows. 



The ariel, with a wide migratory range, has developed 

 two very distinct forms, -to wit : the Sudan type, and that 

 of Somaliland. The extreme divergence between these 

 two has never been adequately recognised. If the reader
