Deep. In New South Wales by the 30th of June 1903, the government had put down 101 bores producing 66 flowing wells and 22 sub-artesian wells, with a total discharge of 54,000,000 gallons a day; and there were also 144 successful private wells.
In South Australia there are 38 deep bores, from 20 of which there is a flow of 6,250,000 gallons a day.
The shores are covered with coral; earthquakes and tidal waves are frequent, the latter not taking the form of bores, but of a sudden steady rise and equally sudden fall in the level of the sea; the climate is rather tropical than temperate, but sickness is almost unknown among the residents.
After a longer or shorter period it enters the alimentary canal of its proper host with drinking-water, or it bores through the skin and reaches the bloodvessels, and is so conveyed through the body, in which it becomes sexually mature.
The female is viviparous, and the young, which, unlike the parent, are provided with a long tail, live free in water; it was formerly believed from the frequency with which the legs and feet were attacked by this parasite that the embryo entered the skin directly from the water, but it has been shown by Fedschenko, and confirmed by Manson, Leiper and others, that the larva bores its way into the body of a Cyclops and there undergoes further development.
The male next casts his cuticle, and by means of his spine bores FIG.
It bores through and enters the developing seed, where it undergoes a moult and becomes legless.
There it feeds first as an internal parasite of the waspgrub, then bores its way out, moults and devours the wasp larva from outside.
In the stomach it casts its membranes and becomes mobile, bores through the stomach walls and encysts usually in the bodycavity of its first and invertebrate host.
If, however, it encounters the host the larva bores its way in, and attacks the liver, mouth or gonad in which it comes to rest.
In this process it is aided by the stylet with which it actively bores its way, throws off its tail FIG.
The evidence therefore of these bores (3 and 4) indicates some material derangement, which is then proved by other bores, either towards the dip or the outcrop, according to the judgment of the borer, so as to ascertain the best position for sinking pits.
The female lays an egg in the unripe nut, on the kernel of which the larva subsists till September, when it bores its way through the shell, and enters the earth, to undergo transformation into a chrysalis in the ensuing spring.
This is shown by palaeontological evidence; and some of the most successful bores, such as those at Coonamble, Moree, Gil Gil and Euroka, have pierced rocks of Triassic age, corresponding with the Ipswich Coal Measures.
When the nuts are about half-grown, the female bores, with its rostrum, a minute hole in the still comparatively soft nut-shell, and deposits an egg within the nut.
The nuts which are infested by this insect are usually the first to fall to the ground; the larva then bores a round hole through the nut shell, by means of its jaws, and creeps out.
