They are, however, erratic animals, and, although they will follow the shepherd wherever he may lead them, they will not mix with the sheep. The latter will walk in a compact flock along the valley, the shepherd leading the way, and the sheep following him, led in their turn by the sound of the bell tied round the neck of the master-ram of the flock. The Goats, however, will not submit to walk in so quiet a manner, but prefer to climb along the sides of the rocks that skirt the valleys, skipping and jumping as they go, and seeming to take delight in getting themselves into dangerous places, where a man could not venture to set his foot. In the evening, when the shepherds call their flocks to repose, they often make use of the caverns which exist at some height in the precipitous side of the hills, as being safe strongholds, where the jackal and the hyæna will not venture to attack them. When such is the case, the shepherds take their station by the mouth of the cave, and assist the sheep as they come sedately up the narrow path that leads to the cavern. The Goats, however, need no assistance, but come scrambling along by paths where no foot but a Goat's could tread, mostly descending from a considerable height above the cave, and, as if in exultation at their superior agility, jumping over the backs of the sheep as they slowly file into the accustomed fold. Friendly as they are, the Goats and sheep never mingle together. There may be large flocks of them feeding in the same pasturage, but the Goats always take the highest spots on which verdure grows, while the sheep graze quietly below. Goats are specially fond of the tender shoots of trees, which they find in plenty upon the mountain side; and, according to Mr. Tristram, by their continual browsing, they have extirpated many species of trees which were once common on the hills of Palestine, and which now can only be found in Lebanon on the east of the Jordan. [Illustration: GOATS ON THE MARCH.] Even when folded together in the same enclosure, the Goats never mix with the sheep, but gather together by themselves, and they instinctively take the same order when assembled round the wells at mid-day. This instinctive separation of the sheep and the goats naturally recalls to our minds the well-known saying of our Lord that "before Him shall be gathered all nations, and He shall separate them one from another, as a shepherd divideth his sheep from the goats: and He shall set the sheep on His right hand, and the goats on His left."
