Although the strength of an elephant is prodigious whenever it is fully exerted, it is seldom that the animal can be induced to exhibit the maximum force which it possesses. A rush of a herd of elephants, with a determined will against the enclosure of palisades used for their capture would probably break through the barrier, but they do not appear to know their strength, or to act together. This want of cohesion is a sufficient proof that in a wild state they are not so sagacious as they have been considered. I do not describe the kraal or keddah, which is so well known by frequent descriptions as the most ancient and practical method of capturing wild elephants; but although in Ceylon the kraal has been used from time immemorial, the Singhalese are certainly behind the age as compared with the great keddah establishments of India. In the latter country there is a ditch inside the palisaded enclosure, which prevents the elephants from exerting their force against the structure; in Ceylon this precaution is neglected, and the elephants have frequently effected a breach in the palisade. In Ceylon all the old elephants captured within the kraal or keddah are considered worthless, and only those of scarcely full growth are valued; in India, all elephants irrespective of their age are valued, and the older animals are as easily domesticated as the young. The keddah establishment at Dacca is the largest in India, and during the last season, under the superintendence of Mr. G. P. Sanderson, 404 elephants were captured in the Garo Hills, 132 being taken in one drive. It is difficult to believe that any district can continue to produce upon this wholesale scale, and it is probable that after a few years elephants will become scarce in the locality. Nevertheless there is a vast tract of forest extending into Burmah, and the migratory habits of the elephant at certain seasons may continue the supply, especially if certain fruits or foliage attract them to the locality. This migratory instinct is beyond our powers of explanation in the case of either birds, beasts, or fishes. How they communicate, in order to organise the general departure, must remain a mystery. It is well known that in England, previous to the departure of the swallows, they may be seen sitting in great numbers upon the telegraph wires as though discussing the projected journey; in a few days after, there is not a swallow to be seen.
