Prior to 1840, and before coffee-plantations had been extensively opened in the Kandyan ranges, there was not a mountain or a lofty feature of land of Ceylon which they had not traversed, in their periodical migrations in search of water; and the sagacity which they display in “laying out roads” is almost incredible.  They generally keep along the backbone of a chain of hills, avoiding steep gradients:  and one curious observation was not lost upon the government surveyors, that in crossing the valleys from ridge to ridge, through forests so dense as altogether to obstruct a distant view, the elephants invariably select the line of march which communicates most judiciously with the opposite point, by means of the safest ford.[1] So sure-footed are they, that there are few places where man can go that an elephant cannot follow, provided there be space to admit his bulk, and solidity to sustain his weight.

[Footnote 1:  Dr. HOOKER, in describing the ascent of the Himalayas, says, the natives in making their paths despise all zigzags, and run in straight lines up the steepest hill faces; whilst “the elephant’s path is an excellent specimen of engineering—­the opposite of the native track,—­for it winds judiciously.”—­Himalayan Journal, vol. i. ch. iv.]

This faculty is almost entirely derived from the unusual position, as compared with other quadrupeds, of the knee joint of the hind leg; arising from the superior length of the thigh-bone, and the shortness of the metatarsus:  the heel being almost where it projects in man, instead of being lifted up as a “hock.”  It is this which enables him, in descending declivities, to depress and adjust the weight of his hinder portions, which would otherwise overbalance and force him headlong.[1] It is by the same arrangement that he is enabled, on uneven ground, to lift his feet, which are tender and sensitive, with delicacy, and plant them with such precision as to ensure his own safety as well as that of objects which it is expedient to avoid touching.

[Footnote 1:  Since the above passage was written, I have seen in the Journal of the Asiatic Society of Bengal, vol. xiii, pt. ii. p. 916, a paper upon this subject, illustrated by the subjoined diagram.

The writer says, “an elephant descending a bank of too acute an angle to admit of his walking down it direct, (which, were he to attempt, his huge tody, soon disarranging the centre of gravity, would certainly topple over,) proceeds thus.  His first manoeuvre is to kneel down close to the edge of the declivity, placing his chest to the ground:  one fore-leg is then cautiously passed a short way down the slope; and if there is no natural protection to afford a firm footing, he speedily forms one by stamping into the soil if moist, or kicking out a footing if dry.  This point gained, the other fore-leg is brought down in the same way; and performs the same work, a little in advance of the first; which is thus at liberty
