The expedition left Fatiko the second morning after its arrival, and continued on its journey to the south. Frank observed that the country was in many places flat and covered with tall grass, a change that was not at all agreeable after the undulating region through which they had been travelling. Abdul said that in the rainy season these flat areas became marshes, through which it was not at all easy to force one's way. "You have to do a great deal of wading," said he, "and sometimes the feet of the porters and animals of a caravan convert the road into a mass of mud. This was the case when Colonel Long made his journey to Ugunda; he frequently fell into mud-holes so deep that he was completely covered and plastered from head to foot, and when he went into camp at night there wasn't a dry or clean thread about him." This region is a favorite hunting-ground of the natives, as it contains few inhabitants, and the wild animals that roam over it are allowed to have their own way, except in the season of the chase. Hunting can only be carried on in the dry season, as neither animals nor man can get about when the rains are falling. The country abounds in game, from the largest size downward. Herds of elephants are numerous, though less so than formerly, owing to the persistency of the hunters and the improved methods of killing the huge beasts since the invention of elephant-rifles and explosive balls. An accident to some of the baggage caused a detention of a couple of hours, and Frank improved the opportunity to go on a tramp of a mile or more, in the hope of bagging something in the way of game. Just as he was ready to turn about to go back to camp he saw a couple of horns above the grass, and, looking closely, traced out the animal to which they belonged. Motioning to Abdul and the gun-bearer who accompanied them to keep perfectly quiet, he crept noiselessly forward, and soon obtained a good position for an effective shot. He fired, and the animal, after giving a single bound in the air, tumbled to the ground. While Frank paused to reload Abdul ran forward and secured the prize. [Illustration: N'SAMMA ANTELOPE.] "It's a N'samma antelope," said he, "one of the finest of the many varieties of antelope in Africa. It is well known to hunters in all the equatorial regions wherever there are wide plains, and is closely allied to the hartbeest, which belongs farther south, but is not uncommon here." "Yes," responded Frank, "we saw one on the day of the great hunt with the Shoolis, and I thought this was the same kind of animal when I spied his horns through the grass." "The name hartbeest was given to him by the Dutch colonists of the Cape of Good Hope," said Abdul, "and the proper name for it is kaama. In scientific works the hartbeest of South Africa is called the _Antilope caama_, while that of the central and northern regions is the _Antilope bubalis_."
