is quite easily to be distinguished from that of Gazella dorcas from its much greater 
length. We now unsaddled the horses, tied them up, and went off in two parties to 
hunt for Reem. The negro led the way in front of me, going slowly and with great 
caution, as the Reem is extremely wary and against the nearly white sand can detect a 
moving object a long way off. We had not walked very far when we saw the head of a 
Reem looking over the top of a sand-ridge at about 300 yards distance. We stayed for 
a long time perfectly still behind a tuft of tall alpha grass, till at last the head disappeared. 
As soon as it was out of sight we ran as hard as we could across the bare sand to the 
top of the next ridge, and again sheltered ourselves behind a tuft of alpha. When we 
looked out cautiously we saw that the Reem had moved on to another sand-hill more to 
our left, and was again showing just the top of his head over it. We had, however, 
considerably reduced the distance. Again he stopped perfectly still for a long time and 
then turned and moved off. We ran to another ridge, and I caught sight of him 
trotting to the top of the sand-hill beyond at about 150 yards. At the top he turned 
and I fired at once and got him. A lucky shot! as the distance was long for so small 
an animal. It was a good male, with horns 13 inches long. I have not seen any much 
longer than these. 
“* After taking the Reem back to the place where we had left the horses, we started 
off again, and during the day saw several small lots containing both males and females 
(4, 5, and 2), but did not get a chance of another shot. Pease also saw a few. 
“ We hunted the sand-hills for two more days; on the third day our negro guide 
took us much farther from camp, running before us with surprising speed and endurance 
for three and a half hours before we halted and tied up our horses. In the evening, 
after walking all day in a hot sun and on soft sand, he showed himself still untired and 
ready to run at the same pace back again to camp. ‘This remarkable man said that he 
had lived for seven years in the desert without sleeping in a house or tent, and had 
hardly tasted water, meat, or bread; during the whole of that time his food consisted 
of dates and camel’s milk, and he attributed his strength to this diet. The long distance 
of our camp from the sand-hills where the Reem is found was a great hindrance, as we 
could not hunt for them at the time they were feeding. By the time we got to the 
ground they were already lying down for the day, generally on the top of the sand- 
ridges, and keeping a watchful look-out. We saw several small herds each day, but 
neither of us ever got another chance of a shot. 
“We were lucky in having calm weather, as a sand-storm in that country is a very 
serious matter. The air gets as thick as during a bad London fog and one cannot see 
even a few yards ahead, making it quite impossible to regain camp, all tracks being 
blotted out in a few minutes by the wind. Our experience of sand-storms was limited 
to one day, our last day in the desert, luckily for us well outside the region of the sand- 
hills, when leaving our caravan behind we rode in 50 kilometres to Biskra in the teeth 
of a cutting wind filled with dust and sand, an extremely painful experience; but we 
were in no danger of losing our way as we were then on the broad track worn by the 
caravans travelling between Biskra and Touggourt.
