CHAPTER VII.

ADELAIDE TO MELBOURNE--THE RABBIT PEST--DANGEROUS EXOTICS.

The distance from Adelaide to Melbourne is about six hundred miles. Our

friends found that the journey was made very leisurely, the trains

averaging not more then eighteen or twenty miles an hour. For quite a

distance out of Adelaide the train ascends an incline as far as Mount

Lofty station, where the hill or mountain of that name is situated. On

the way up the last of the incline our friends watched with a great deal

of interest the plains stretching out below them, and the city which

they had just left lying at their feet like a section of carpet laid off

into ornamental squares. Beyond Mount Lofty station the route descended

into the valley of the Murray River, whose waters could be seen winding

like a thread through the yellow soil.

"This is the longest river in Australia, is it not?" queried Ned.

"Yes," replied the doctor, "it is the longest and largest river, and, as

you have already learned, it is the only one that remains a real river

throughout the year. Its mouth is not many miles from Adelaide, and a

considerable part of its course is through South Australia."

"I wonder they didn't establish the capital city at the mouth of the

Murray," remarked Harry; "they would have had the advantage of a

navigable stream, which they have not in the present location."

"Yes, that is quite true," Dr. Whitney replied; "and they would have

illustrated the saying of a philosopher, that great rivers nearly always

run past large cities, but there was a practical difficulty in the way,

of which you are not aware."

"What is it?"

"The Murray at its mouth has a bar that is very difficult and dangerous

to cross, and a large area at its entrance consists of shallow water.

The mouth of the river, furthermore, is swept by southerly winds, which

bring in great waves that have their origin in the neighborhood of the

South Pole. Consequently it was concluded that the location of the city

at the place with the largest entrance into the sea would not be

advantageous, and a location on Spencer's Gulf was considered

preferable."

"Very good reasons," said Ned, "and I have no doubt that the founders of

Adelaide acted wisely. They certainly have a very prosperous city where

they are, although their seaport is several miles away."

The train increased its speed as it descended the incline, and the

youths found plenty of occupation and amusement in studying the scenery

on each side of them, and noting the handsome residences of the

merchants and other well-to-do inhabitants of Adelaide. The river was

crossed by means of an iron bridge, a substantial structure which was

evidently built to last. After crossing the Murray, the railway

proceeded for awhile along its valley, and gradually left it to enter a

region of long-continued monotony.

"For hours in succession," said Harry in his journal, "we had little

else but scrub. I imagine that when the surveyors laid out the railway

line, they took their bearings by observation of the moon and stars, and

laid it directly across from one side of the scrub country to the other.

Scrub land is land covered with bushes. There are not many varieties of

bushes, and this fact helps along the monotony. There is one bush that

looks like an umbrella turned bottom upwards, and another that resembles

an umbrella standing upright, as one holds it to keep off the rain. Then

there are bushes and trees, some of them shaped like bottles, others

like sugar loaves, and some like nothing else that I can think of at

this moment. They vary from three or four feet in height up to fifteen

and twenty feet, and sometimes we found them of a height of thirty feet

or more.

"Mile after mile it is the same. I have heard what a terrible thing it

is to be lost in the scrub. I can well understand that it is terrible,

and can also understand how easily such a calamity could be brought

about. One mile of scrub is exactly like another mile, or so very nearly

like it that it is next to impossible to tell the difference. I have

heard that people who stepped only a few yards from the side of the road

have wandered for days before finding their way again, or have been

sought for by many people before they were found. Many a man has lost

his way in the scrub and never been heard of again, or perhaps years

after his bones were discovered bleaching at the foot of a tree, where

he had sat or lain down for his last rest when he could go no further."

A portion of the road from Adelaide to Sydney is called "the

ninety-mile desert," in distinction from the rest of the scrub region.

It was a great relief to any one to get out of this desert country, and

reach the region of farms, and fences, cattle or sheep pastures, and

cultivated fields. In some of the districts through which our travelers

passed they saw great numbers of rabbits, and on calling attention to

them, a gentleman who was in the railway carriage told them something

about the rabbit pest from which the Australian colonies are suffering.

"If you want to make a fortune," said the gentleman, "find some way for

destroying the rabbits in Australia. There is a standing reward of

twenty-five thousand pounds (one hundred and twenty-five thousand

dollars of your money) for any method that proves successful. The reward

is offered by the colony of New South Wales, and the other colonies will

pay as much more."

"Were there rabbits in this country when it was first discovered?" Harry

asked.

"There were no rabbits here," was the reply; "nor any animals like them.

In 1851, a gentleman living near Dunedin, New Zealand, was on a visit to

the old country, and it occurred to him that it would be a nice thing to

have rabbits in New Zealand, so that they could amuse themselves by

chasing the little creatures with dogs. On his return from England he

brought seven rabbits, and they were the progenitors of all the rabbits

in New Zealand, Australia, and Tasmania. For a few years, as fast as

rabbits were obtainable they were distributed throughout the colonies,

but it was not long before the distributors found out their mistake.

"The rabbits increased and multiplied at a terrific rate. How many

there are now in the colonies, nobody can tell, as it is impossible to

take a census of them, but they certainly amount to many millions. They

have destroyed millions of acres of sheep pasturage, so that many farms

which once supported great numbers of sheep have been deserted in

consequence of the rabbits. Let me give you an illustration that I know

about, as I was one of the sufferers by these vermin. Fifteen years ago,

I owned an interest in a sheep run on the bank of the Murray River in

the colony of Victoria. Our holding extended back into the dry and

comparatively worthless country.

"The rabbits got in there, and gradually the sheep were starved out.

Year by year the number diminished, and five years ago I sold my

interest in the run for a very small sum. From two hundred thousand

sheep, the number had diminished to twenty-five hundred, and these were

dying in the paddock for want of food. The rabbits were the cause of the

whole destruction. They had eaten up all the grass and edible bushes,

and it was some consolation to know that they were themselves being

starved out, and were dying by the hundreds daily. When the rabbits

there are all dead the place can be fenced in, so that no new ones can

get there, and it is possible that the grass will grow again, and the

run once more become a place of value.

"The story I have just told you," the gentleman continued, "is the story

of a great many sheep and cattle runs all over Australia and New

Zealand. All sorts of means have been resorted to to get rid of the

pest, and while some have been partially successful, none have been

wholly so. The best plan is the old one, to lock the stable before the

horse is stolen; that is, enclose the place with rabbit-proof fences

before any rabbits have been introduced. The Australian rabbit is a

burrowing animal, and unless the fence is set well into the ground, he

is very apt to dig under it. Thus it has happened that many an estate

has become infested, even though the owners had gone to the expense of

enclosing it.

"Most of the cities of Australia and New Zealand have a rabbit-skin

exchange, just as you have a cotton exchange in New York. At these

exchanges ten or fifteen millions of rabbit skins are sold every year,

or an aggregate perhaps of fifty or sixty millions, and yet the number

does not decrease perceptibly. Factories have been established for

preserving the meat of the rabbits in tin cans, and sending it to market

as an article of food. It was thought that this would certainly reduce

the number of rabbits, but it has not yet succeeded in doing so.

"Various kinds of apparatus have been devised for filling the dens of

the rabbits with noxious gases that kill them, but the process is too

expensive for general introduction; and, besides, it does not work well

in rocky ground. Rewards are given both by the government and by the

owners of land for the destruction of rabbits, and these rewards have

stimulated men, who go about the country with packs of dogs to hunt down

the rabbits for the sake of the bounty. Sometimes the whole population

turns out in a grand rabbit hunt and thousands of rabbits are killed.

Pasteur, the celebrated French chemist, proposed to destroy the rabbit

population by introducing chicken cholera among them; he thought that

by inoculating a few with the disease he could spread it among the

others, so that they would all be killed off. He admitted that the

chicken population would be killed at the same time, but none of us

would object to that if we could get rid of the rabbits, as we could

easily reintroduce domestic fowls."

Ned said that he wondered why the rabbits increased so rapidly in the

Australian colonies and not in the United States or England.

"Here is the reason of it," said the gentleman. "In America there are

plenty of wild animals, like wolves, weasels, foxes, ferrets, and the

like, to keep down the rabbit population, but here there is not a single

animal to interfere with them. They have no natural enemies whatever,

and consequently have things entirely their own way. They breed several

times a year and begin to breed very young, so that a pair of rabbits

let loose in a given locality will in a few years amount to thousands or

even to millions. There, look at that piece of ground and see what you

think of it."

The boys looked where the gentleman indicated, and saw what seemed to be

a field of tall grass or grain waving in the wind. A nearer inspection

showed that the ground was covered with rabbits, and it was the

movements of the animals that caused the illusion just described.

"Rabbits are not the only pests from which the colonies have suffered,"

the gentleman continued; "I will tell you about more of them.

"You must bear in mind," said their informant, "that when Australia was

settled it contained very few of the products, either animal or

vegetable, of other parts of the world. Among the animals there were no

noxious ones except the dingo, or wild dog, which was found in various

parts of the country. His origin has been a matter of conjecture, some

believing that he is descended from dogs which were left here by those

who discovered the continent, while others think he is indigenous to the

soil. All the other animals, and they were not numerous, were harmless

in their character. There are eight kinds of kangaroos, all of them

herbivorous. They are, as you are doubtless aware, marsupials, that is,

they carry their young in a pouch until they are able to run about by

themselves. The dingo lived by feeding on the kangaroos, and thus kept

down the number of those animals.

"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?"

"I refer particularly to the Scotch thistle," said the gentleman, "which

is not particularly unlike the other thistles with which we are

familiar. You know that the thistle is the emblem of Scotland, and may

be said to be worshipped by all patriotic Scotchmen. Well, it happened

that a Scotch resident of Melbourne, while visiting the old country,

took it into his head to carry a thistle with him on his return to

Australia. So he placed the plant in a pot and watered it carefully

every day during the voyage from London to Melbourne. When he arrived

his performance was noticed in the newspapers, and a subscription dinner

was arranged in honor of the newly arrived plant. About two hundred

Scotchmen sat down to the dinner, at which the thistle was the

centerpiece and the great object of attraction. Speeches were made, and

the festivities continued to a late hour of the night. The next day the

thistle was planted with a great deal of ceremony, and more speeches in

the public garden at Melbourne, and it was carefully watched and tended

by the gardener, who happened to be a Scotchman.

"Well, the thistle blossomed and everybody rejoiced. You know how the

seeds of that plant are provided with down, that enables them to float

on the wind. The seeds of that thistle were borne on the breezes, and

all over the colony of Victoria they found a lodging in the soil, grew

and prospered, and sent out more seeds. That thistle has been the cause

of ruin to many a sheep and cattle run all over Australia. Thousands,

yes, millions, of acres of grass have been destroyed by that pernicious

weed. Anathemas without number and of the greatest severity have been

showered upon the thick-headed Scotchman who brought the plant to

Australia, and the other thick-headed Scotchmen who placed it in the

public garden.

"While I am on this subject," the gentleman continued, "I may as well

tell you of a very curious circumstance in New Zealand."

"What is that?"

"When the sheep farmers first established their business in the mountain

regions of New Zealand, they observed flocks of parrots occupying the

forest, and living entirely upon fruits and vegetables. They were very

pretty birds and nobody thought that any harm would come from them, in

view of their habits of life. The farmers used to kill some of their

sheep for food purposes, and leave the meat hanging out over night in

the cool air. It was observed that the parrots got in the habit of

coming down to the meat frames and picking off the layers of fat,

particularly those around the kidneys. Their fondness for this kind of

food seemed to increase as time went on, and they finally became such a

nuisance as to compel the herders to give up their practise of leaving

the meat out of doors in the night-time.

"After a while the farmers occasionally found the fattest and best of

their sheep dead or dying of wounds across the smaller part of the back

directly in the region of the kidneys. Nobody could tell how the wounds

were made, but it was evident that the mischief-makers were numerous, as

a good many sheep, always the finest of the flock, were killed. Finally,

one of the men employed about a sheep run ventured to suggest that it

must be done by the parrots. His suggestion was ridiculed so earnestly

that the man was sorry he had made it, but he gave as his reason for it

the fact that he had seen a parrot perched on the back of a sheep and

the bird flew away when he approached.

"Watchers were set over the sheep, and the suggestion of the man proved

to be the correct one. How the birds ever connected the existence of the

fat which they tore from the carcases on the meat frames with the

location of the same fat in the living animal, no one can tell, but

certain it is that they did so. It was found that a parrot bent on

securing a meal, would fasten his claws in the wool of the sheep, and

then with his powerful beak he would tear away the skin and flesh until

he reached the fat of which he was in search around the kidneys of the

struggling animal. It was impossible for the sheep to shake him off;

whether it ran or lay down and writhed in its agony, the bird retained

its hold until its object was accomplished."

"Of course this led to a war of extermination against the parrots, did

it not?"

"Certainly it did. As soon as the fact was well established the colonial

government offered a reward of one shilling for each parrot's head, and

the business of hunting these birds began at once. Formerly they used to

come freely into the presence of man, but now they shun him, and it is

very difficult to find them. They live in the forest, concealing

themselves in the daytime, and only coming out at night. In fact, their

depredations were committed in the night-time, and that is the reason

why their offences continued so long without being discovered."

"Did they cause great destruction among the flocks of sheep?"

"Yes, until they were found out and the war began against them they were

terribly destructive. One man lost two hundred sheep out of three

hundred, another lost nineteen out of twenty, and several others in the

same proportion. Even now, although the number of parrots is diminished

enormously, the flocks in the region where they abound lose at least two

per cent. every year from that cause."

"Is there any way of exterminating them by poison?"

"No way has been discovered as yet, as the birds are very cunning and

cannot be readily induced to take poisoned food. They are more wary in

this respect than rabbits and sparrows, as both of these creatures can

be poisoned, though the danger is that in attempting to poison them the

food is apt to be taken by domestic animals or fowls."

"Speaking of poisoning reminds me of an instance in Queensland some

years ago, where there was a large number of blacks inhabiting the

forest near a sheep station.

"The owner of the station had been greatly annoyed by the blacks, who

had killed many of his sheep, and in several instances had threatened

the shepherds with death, and driven them from their places. He

determined to get even with them, and this is the way he did it. He

loaded a cart with provisions such as flour, sugar, bacon, tea, and

other things, which were distributed to the shepherds once a week. Then

the cart started apparently on its round. Near the place where the

blacks were congregated one of the wheels of the cart came off, and at

the same time the vehicle became stuck in a gully. The driver took his

horses from the shafts and rode back to the station for help, leaving

the cart and its load unguarded.

"Here was a fine opportunity for the blacks to exercise their thieving

propensities, and they did not miss it. In less than an hour the cart

was stripped of everything edible, flour, sugar, and everything else

being carried away. When the driver returned, he found only the empty

vehicle with which to continue his journey.

"That afternoon the blacks had a grand feast over the stolen property.

All the members of the tribe came together and took part in the feast,

about two hundred in all. It so happened that everything edible had been

dosed with strychnine before the cart was loaded, and in a few hours

all who had partaken of the feast were dead. Much as the white people

around there had been annoyed by the blacks, there were few, if any, to

approve of this wholesale poisoning which the sheep owner had undertaken

entirely on his own responsibility."

"I suppose it is due in some measure, at least, to performances of this

sort that the blacks are diminishing in number," Dr. Whitney remarked.

"No doubt that has a good deal to do with the matter," was the reply. "I

don't know of any other instances than this of wholesale poisoning, but

I do know that in a good many instances, black men have been shot down

by whites for the reason that they had speared cattle or committed other

depredations. The blacks have been treated very much the same way as

your American Indians, and generally with as little provocation; but,

beyond all this, it is well known that the number of births among them

every year is considerably less than the number of deaths from natural

causes. Some people believe that the blacks are addicted to infanticide,

and that many of their children are put to death to save the expense of

bringing them up. Understand me, nobody knows positively that this is

the case, but only surmises it."
