In the Zoological Gardens of Adelaide I saw the only laughing jackass that ever showed any disposition to be courteous to me. This one opened his head wide and laughed like a demon; or like a maniac who was consumed with humorous scorn over a cheap and degraded pun. It was a very human laugh. If he had been out of sight I could have believed that the laughter came from a man. It is an odd-looking bird, with a head and beak that are much too large for its body. In time man will exterminate the rest of the wild creatures of Australia, but this one will probably survive, for man is his friend and lets him alone. Man always has a good reason for his charities towards wild things, human or animal when he has any. In this case the bird is spared because he kills snakes. If L. J. he will not kill all of them. In that garden I also saw the wild Australian dog--the dingo. He was a beautiful creature--shapely, graceful, a little wolfish in some of his aspects, but with a most friendly eye and sociable disposition. The dingo is not an importation; he was present in great force when the whites first came to the continent. It may be that he is the oldest dog in the universe; his origin, his descent, the place where his ancestors first appeared, are as unknown and as untraceable as are the camel's. He is the most precious dog in the world, for he does not bark. But in an evil hour he got to raiding the sheep-runs to appease his hunger, and that sealed his doom. He is hunted, now, just as if he were a wolf. He has been sentenced to extermination, and the sentence will be carried out. This is all right, and not objectionable. The world was made for man--the white man. South Australia is confusingly named. All of the colonies have a southern exposure except one--Queensland. Properly speaking, South Australia is middle Australia. It extends straight up through the center of the continent like the middle board in a center-table. It is 2,000 miles high, from south to north, and about a third as wide. A wee little spot down in its southeastern corner contains eight or nine-tenths of its population; the other one or two-tenths are elsewhere--as elsewhere as they could be in the United States with all the country between Denver and Chicago, and Canada and the Gulf of Mexico to scatter over. There is plenty of room. A telegraph line stretches straight up north through that 2,000 miles of wilderness and desert from Adelaide to Port Darwin on the edge of the upper ocean. South Australia built the line; and did it in 1871-2 when her population numbered only 185,000. It was a great work; for there were no roads, no paths; 1,300 miles of the route had been traversed but once before by white men; provisions, wire, and poles had to be carried over immense stretches of desert; wells had to be dug along the route to supply the men and cattle with water.
