Queensland's annual output is between 750,000 and 800,000 oz.; the number of men engaged in goldmining is io,000.
In New South Wales the greatest production was in 1852, soon after the first discovery of the precious metal, when the output was valued at £2,660,946; the production in 1905 was about 270,000 oz., valued at £1,150,000.
In 1905 the production amounted to 1,983,000 oz., valued at £8,300,000.
The electromotive force of each cell is i 07 volts and the resistance 3 ohms. The Fuller bichromate battery consists of an outer jar containing a solution of bichromate of potash and sulphuric acid, in which a plate of hard carbon is immersed; in the jar there is also a porous pot containing dilute sulphuric acid and a small quantity (2 oz.) of mercury, in which stands a stout zinc rod.
For the first oz., and i3/4d.
The internal rate is 15c. (i3/4d.) per 3/4 oz.; post-cards foe.
The less robust species, such as Sphacelaria scoparia, which do not adhere well to paper, may be made to do so by brushing them over either with milk carefully skimmed, or with a liquid formed by placing isinglass (4 oz.) and water (11 oz.) in a wide-mouthed bottle, and the bottle in a small glue-pot or saucepan containing cold water, heating until solution is effected, and then adding i oz.
Gold-mining and quartz-mining are its principal industries, and in 1907 Nevada county's output of gold (104,J90.76 oz., worth $2,162,083) was second only to that of Butte county (134,813.39 oz., worth $2,786,840) in California; the county is the leading producer 1 Died the 21st of September, 1890, and Frank Bell became governor by virtue of his office as lieutenant-governor.
In West Siberia, however, quartz-mining is steadily increasing in importance: whereas in 1900 the output of gold from this source was less than 10,000 oz., in 1904 it amounted, to close upon 50,000 oz.
On the other hand gravel-washing gives a declining yield in West Siberia, for while in 1900 the output from this source was approximately 172,000 oz., in 1904 it was only 81,000 oz.

If the ray be parallel to OX, and the direction of vibration parallel to OZ, we have E =o, 7 7 = o, while I is a function of x and t only.
The force operative upon the positive half is parallel to OZ, and of amount per unit of area equal to - b 2 D = b 2 kD cos nt; and to this force acting over the whole of the plane the actual motion on the positive side may be conceived to be due.
According to (18), the effect of the force acting at dS parallel to OZ, and of amount equal to 2b2kD dS cos nt, will be a disturbance - dS sin cos (nt - kr) (20), regard being had to (12).
This therefore expresses the secondary disturbance at a distance r and in a direction making an angle cp with OZ (the direction of primary vibration) due to the element dS of the wave-front.
Deep. The yield of the Rand mines, in 1887 but 23,000 oz., rose in 1888 to 208,000 oz.
In 1892 the yield was 1,210,000 oz.: in 1896 it exceeded 2,280,000 oz.
In 1905 when a full supply of labour was again available the output was 4,760,000 oz., in which year the sum distributed in dividends to shareholders in the Rand mines was over £4,800,000.
Though several large nuggets have been found (the largest weighing 215 oz.), the total production is not great, the highest output obtained by washing being worth about £300,000 in one year.
Work was begun in 1895, and the yield of gold in that year was 274 oz., which increased to 893 oz.
As an example of the general equations, take the simplest case of a uniform field of gravity, with Oz directed vertically downward; employing the gravitation unit of force, 1 dp i dp t dp dp/dz = p = pzn (4) z n+I pz 1 /n p-p n-H ?t), (5) supposing p and p to vanish together.
If homogeneous liquid is drawn off from a vessel so large that the motion at the free surface at a distance may be neglected, then Bernoulli's equation may be written H = PIP--z - F4 2 / 2g = P/ p +h, (8) where P denotes the atmospheric pressure and h the height of the free surface, a fundamental equation in hydraulics; a return has been made here to the gravitation unit of hydrostatics, and Oz is taken vertically upward.
(7) Interchanging these values =m log r, 4, = mO, 4,+4,i =m log rei e (8) gives a state of vortex motion, circulating round Oz, called a straight or columnar vortex.

For in a rigid body, rotating about Oz with angular velocity the circulation round a curve in the plane xy is x ds yds) ds = times twice the area.
Yes, my dear; I am Oz, the Great and Terrible.
"It's better," replied Oz, promptly.
"Now," said the Wizard of Oz, "having created something from nothing, I will make something nothing again."
"The Wizard of Oz has always been a humbug," agreed Dorothy.
Our friend Oz is merely a humbug wizard, for he once proved it to me.
"The girl that rules the marvelous Land of Oz," was the reply.
She's a friend of mine, for I met her in the Land of Ev, not long ago, and went to Oz with her.
Yes. The first time I went to Oz I found you there, ruling the Emerald City.
But the second time I went to the Land of Oz I owned the Nome King's Magic Belt, which is much more powerful than were the Silver Shoes.
Anyone in a fairy country like the Land of Oz can do anything with it; so I left it with my friend the Princess Ozma, who used it to wish me in Australia with Uncle Henry.
"And when you make a sign she will bring you to her in the Land of Oz?" continued the boy.
"They live in Oz yet," said the girl, "and are very important people."
You'll just love the folks in Oz, when you get acquainted.
Why, it's Oz, the Wonderful Wizard, come back again!
His fame had not been forgotten in the Land of Oz, by any means.
"Oh, no," she hastened to say, "there may be many more like you in the place you came from, but in Oz any horse but a Sawhorse is unusual."
Please tell me, Mr. Wizard, whether you called yourself Oz after this great country, or whether you believe my country is called Oz after you.
I ordered the Emerald City to be built just where the four countries cornered together, and when it was completed I announced myself the Ruler of the Land of Oz, which included all the four countries of the Munchkins, the Gillikins, the Winkies and the Quadlings.
"That is quite a history," said Ozma; "but there is a little more history about the Land of Oz that you do not seem to understand--perhaps for the reason that no one ever told it you.
"Oz can do some good tricks, humbug or no humbug," announced Zeb, who was now feeling more at ease.
I'm very certain, Oz, that you gave me the best brains in the world, for I can think with them day and night, when all other brains are fast asleep.
I won't have any quarrelling in the Land of Oz, I can tell you!
How stupid and ignorant you are, in the Land of Oz, and what dreadful things you feed upon!
I know I'm not much account; but I'm the only horse in all the Land of Oz, so they treat me with great respect.
Just then the girlish Ruler of Oz opened the door and greeted Dorothy with a good-morning kiss.
