Lastly, there is the blue vegetable substance called indigo, which is obtained from small bushes or plants by a simple process of fermentation. It is mostly used to dye clothing, and has been known in Europe since the Indian campaign of Alexander.
Wild Elephants
The home of the wild elephant is the forests of India, the Malay Peninsula, Ceylon, Sumatra, and Borneo, while another species is found in Africa. They live in herds of thirty or forty, and every herd forms a separate community. The leader of the herd is a full-grown bull with large, strong tusks, whom all the others obey with the greatest docility. When they wander through the forest, however, or fly before danger, the females go in front and set the pace, for they alone know how fast their young ones can travel. Their senses of smell and hearing are remarkably acute; they are of a good-tempered and peaceable disposition, and do not care to expose themselves to unnecessary risks. They are therefore not very dangerous to man, unless when attacked; but man is their worst enemy.
In India wild elephants are caught to be tamed and employed in labour. They are captured in various ways, but usually tame elephants are used to decoy the wild ones. Expert elephant-catchers hide themselves as well as they can on the backs of tame animals and drive them into a herd of their wild relations. When a full-grown male has been separated from the herd, he is beset on all sides by his pursuers and prevented from sharing in the flight of his companions. They do him no injury, but only try to tire him out. It may be two whole days before he is so exhausted that, come what may, he must lie down to sleep. Then the men drop down from the tame animals and wind ropes round his hind legs, and if there is a tree at hand they tie him to it.
In Ceylon there are wonderfully smart and expert elephant-catchers who hunt their game in couples without the help of tame decoys. They search through the woods and thickets and follow a spoor when they come across it, being able to judge from the footprints how long ago the trail was tramped out, how many elephants there were, and whether they were going fast or slowly. The smallest mark or indication on the way, which a stranger would not notice, serves as a guide to them. When they have found the troop they follow it silently as shadows; they creep and crawl and sneak along the woodland paths as cautiously as leopards. They never tread on a twig which might crack, they never brush against a leaf which might rustle. The elephants, for all their fine scent and sharp hearing, have no suspicion of their proximity. The men lie in wait in a close thicket where the elephants can only move slowly, throw a noose of ox hide before the animal's hind leg, and draw it tight at the right moment. Then the elephant finds out his danger, and, trumpeting wildly, advances to attack, but the men scurry like rats through the brushwood and strengthen the snares time after time until the animal is fast.
In India whole herds are also captured at once, and this is the most wonderful sight it is possible to conceive. A place is known in the forest where a herd of perhaps a hundred animals has made its home. Natives who are experienced in elephant-catching are called out, and all the tame elephants procurable are assembled. A chain of sentinels is posted round the herd, making a circle of several miles. The men construct a fence of bamboos as quickly and quietly as possible, and keep to their posts for nearly ten days. The elephants become restless and try to break through, but wherever they turn they are met with cries and shouts, blank gunshots and waving torches. They retire again to the middle of the enclosure. If they make an attempt in another direction, they are met in the same way, and at last, submitting to their fate, they stand in the middle where they are least disturbed.
Meanwhile within the circle a very strong enclosure has been erected of poles, trunks, and sticks 12 feet high, with a diameter of 160 feet at most. The entrance, which is 12 feet broad, can be closed in a moment by a huge falling wicket or gate. Now it stands open, and from the two sideposts run out two long palisades of stakes, forming an open passage to the entrance. The two fences diverge outwards and are nearest to each other at the entrance.
When all is ready the great ring of beaters closes up round the herd, and scares and chases them with shouts and noise towards the opening between the palings. Fresh parties of beaters rush up, and when the elephants can find no other way free they dash in between the fences and into the pen, whereupon the entrance is closed with the heavy gate. They are caught as in a trap. They may, indeed, gather up their strength and try to break through the fence of poles, but it is too stoutly built and the beaters outside scare them away.
