“Horned cattle, horses, and sheep were introduced and successfully raised. The wild dogs killed sheep and calves, and therefore the inhabitants set about killing them. As the dogs decreased in number the kangaroos increased, and they threatened to drive the sheep to starvation by eating up all the grass. Many a sheep run was rendered worthless by the kangaroos, and so it became necessary to establish methods of reducing the number of the latter. Battues or hunts were organized, the people gathering from all directions at an appointed time and place, and driving the kangaroos into pens or yards, where they were slaughtered by the thousand. You will probably have an opportunity of seeing a kangaroo hunt before you leave Australia.

“There were very few native fruits, and we introduced the fruits of England and other parts of the world very successfully. We introduced garden plants and vegetables in great numbers, and nearly all of them turned out to our satisfaction, though this was not uniformly the case.

“You know that innocent and very acceptable plant called the watercress, which is sold in great quantities for table use in London, New York, and other English and American cities. Well, we brought the watercress to the Australian colonies, and it grew and thrived wonderfully. It grew altogether too well and thrived a great deal more than we could have wished, as it has choked our rivers, and caused freshets and floods which have devastated farms and fields to a large extent, and on several occasions have been destructive to human life.

“We introduced the sweet briar, thinking it would form an ornament and fill the air with its perfume. Instead of being ornamental, it has become an impenetrable bush, which neither man nor cattle can go through. It has become a nuisance, spreading over the ground and destroying pasturage, and we heartily wish that not a twig of it was ever brought here.

“When we began to grow fruits we found ourselves annoyed by insects of various kinds, the same sort of insects that are known to fruit growers everywhere. In order to get rid of them, we brought the English sparrow here. He is of great use to the fruit grower in the old country, as he lives principally on insects, or at any rate has the reputation of doing so, and he does not often attack the fruit.

“Well, we got the sparrow here, and he increased and multiplied until he became very numerous, and what do you suppose the little wretch did?

“He did not do anything that we wanted him to do. He abandoned his English practise of eating insects, and lived wholly upon grain and fruit. In the fruit season he is a perfect terror in the devastation he makes among our fruit trees. A flock of sparrows will make its appearance in a cherry garden where there are twenty, fifty, or perhaps a hundred cherry trees bending beneath a burden of fruit just about ripe enough to be picked. They save the owner the trouble and expense of picking his fruit, as they take entire charge of it, and in a few days the whole crop is ruined. Other fruit suffers in the same way, and the testimony is the same from all parts of Australia. One of the colonial governments had an investigation of the subject at one time, and the testimony was something appalling. The sparrows abound here in countless millions, all of them descended from fifty birds that were imported about the year 1860. The owners of vineyards, as well as the fruit farmers, complain of the ravages of the sparrows, and at the official investigation that I mentioned one vine grower testified that his crop of grapes the previous year would have been two tons, but the sparrows destroyed the entire lot.

“Another bird almost as destructive as the sparrow is the mina or mino, a bird which was brought here from India. It is quite a handsome bird, and can learn to talk almost as readily as the parrot, and that is why it was brought here. It lives on fruits and vegetables, and has very nearly the same habits as the sparrow. The colonial government have placed a bounty upon the heads and eggs of the sparrow, and also on those of the mina. A great many boys and men, too, make a fairly good revenue in killing the birds or plundering their nests. The birds are trapped, shot, or poisoned, but their number does not seem to diminish.

“Somebody brought a daisy to Australia, as it is a very popular flower in England, and was expected to remind the English settler of his old home. It has spread very rapidly, and on thousands upon thousands of acres it has rooted out the native grasses and taken full possession of the soil. Another plant has a history which would be ludicrous if it were not so serious, and that is the thistle.”

“You mean the regular thistle, such as is known in England and the United States?”
