of the negative being broken in transport or lost, a 

 copy of the subject would still be left. Development 

 presents no difficulties, if tanks be used and tabloid 

 chemicals taken. The Agfa Acid Fixing Salts are 

 convenient, as they are sold in tins containing 

 sufficient hypo, to make 35 oz. — approximately a 

 tankful. 



A spare mirror and ground-glass should be carried, 

 cut to Jit, as without them a reflex camera is practically 

 useless. The use of an actinometer will save a great 

 wastage of plates ; but it must be noted that the 

 sensitive paper darkens more slowly in a dry and 

 more quickly in a damp climate, and an allowance 

 must be made in calculating the exposure. An 

 invaluable rule, not often mentioned, is that the 

 actinometer gives the correct exposure for normal 

 subjects only ; for near objects, double the exposure 

 should be given, for distant objects, one quarter of 

 what is indicated by the actinometer. 



One word of warning is needed before I finish. 

 To penetrate into the little-known regions of Jubaland 

 requires a great deal of hard travelling ; many a 

 weary hour must be faced. Hunger, heat, fatigue, 

 illness and especially thirst must be endured almost 

 daily, and in the far interior there is always the 

 danger of an attack by the natives. But, on the 

 other hand, Jubaland contains a variety of game 

 unobtainable elsewhere, and the melancholy of its 

 scenery cannot but attract those who appreciate 

 Nature in her sterner moods.
