MtlTiiillCS 0 Scene IX THE 6000-FOOT LEVEL Facing the facts is our first duty with regard to every problem. Sir J. Arthur Thomson, in Biology for Everyman This is the section which represents mathe- matics. What a waste of paper in om' pre- cious school magazine! you may say. Well, you have made a mistake if you hold that opinion of this most useful of all subjects. Perhaps you sympathize with yourself bc:- cause of all the hard, brain-racking, heart- rending work you are required to put into this subject. Poof! Why, Al-Khowarzimi spent a lifetime trying to solve a quadratic equation. He finally succeeded, Nowadays we are taught how to do such a thing in a single period. And what is more, we go home that night a.nd do twenty or thirty. Pythagoras was another old-timer in the history of mathematics. He was born in 582 B.C. He was a great expense to his father, as he had a great liking for going places, and his hotel bills were always sent to Papa Pytha- goras. One day, when Pythagoras the Younger was in Egypt, somebody put the silly idea into his head of inventing a new theorem in Geometry. This he did, and called it Theorem Twelve, Book TWO. Al- though he did not know it at the time, he was laying the foundation for a great many other geometrical theorems. Imagine that you are in Greece, a great many years ago, and that you Wish to buy a pair of sandals, or Grecian oxfords. You en- ter a little shop and the purchase is made as as it would be in 1935-until the storekeeper finds that you have given him too much money. At this stage, you might as well sit down, for the storekeeper is about to begin the long and tedious operation of paying you the correct change. He takes a. peculiar- looking board from a hook on the wall, and picks up a handful of counters, or checkers, Is he going to play a game with you? No! This board is the Abacus, that wonderful in- strument with which the storekeeper calcu- lates the amount of change he owes you. The counters are placed on numbered lines in what seems to be a pattern of strange de- sign. Then the dealer counts them, length- wise, crosswise and everywise. After a great deal of counting on his fingers and of mum- bling to himself lmental arithmeticll, he gives you your change, which you must trust to be correct. If you think that you have been cheated, you are out of luck, for no amount of coaxing would persuade that dealer to repeat his work. The mental arithmetic that the store- keeper of that period did on his hands was really part of a queer system of numbers. Each number was made by holding the hand in a certain position, with the fingers twisted into knots and other shapes, to form a sign numeral. How queer it would be if we did our pre- sent daily shopping under such conditions as these! It might be a means of saving more of our income, because our days Would be much too short, and our purchases too numerous. for all this tedious counting and reckoning. All branches of mathematics have advanced a great deal since the time of the early Greeks and Egyptians, and our present explorers in those subjects are not as handicapped as were their ancient masters. ESSES You will find good reading to the last page.

46 ..... ., The PORCUPINE QUILL l on his shoulder. I also remember how I smacked my lips on that deer the next day at dinner. The thing that stands out most and was of the greatest importance is the making of my kiddy-car. My father made it for me and then took the wheels off my crib to c0m- plete the toy. .That kiddy-car was the best in the world in my estimation, and I can still see it standing on the wheels from my crib.

Everything must be settled, once and for all, before the story ended. My youthful feeling of justice de- manded that good People should be re- warded, and bad people punished, and unless the story worked out in that way, there was something Wrong with it. To me fairies were the most enticing, the inhabitants of the earth. most important Every flower cup was a fairy's bedroom, every mushroom a dining-table.

48 The PORCUPINE QUILL 'T Tool After Tool At evening when our chores are done, We take our books out one by one, And look them over carefully, For homework is our specialty. First to our 'imaths we always turn, We like them for the things we learn Which sharpen, clear and train the mind And urge us on our goals to find. And later on, in years to come, When we, our long-sought goals have won, We'll see that maths -tool after tool- Just as we used them while at school, Have paved the way for us to win A peaceful place 'midst the world's mad din. LESTER I-HLL For those readers who like to try their mathe- matical ability in working out unusual pro- blems, I submit the following:- 1. If a third of six were three, What would a fourth of twenty be? 2. By using all the digits from 1 to 9 in- clusive, and putting them down in two columns, arrange them so that the sum will be 100. 3. Arrange 6 matches in the following form whose value is L- .L By moving 7 V11 only one match to another position, change the value from Lto 1 7 Scene X: THE 2800-FCOT LEVEL To exalt the present and fthe real. To teach the average man the glory of his daily work or trade. Walt Whitman The Process of Extracting Gold from the Rock in Mclntyre Mill The rock is first crushed down to six-inch boulders underground. When the ore comes to the surface it passes a magnet which takes all the steel out, then it goes through a gyratory or cone crusher which crushes the rock to fine pebbles. The ore is then taken up past another magnet and goes through a weightometer which measures the number of tons of ore. It is then taken across a tripper which distribultes the ore evenly into ore- pockets. From the ore-pockets it goes across vibrating screens which separate the large particles from the small. The large particles go to the rolls while the small ones are taken across a tripper and evenly distributed in an ore bin. In the rolls the ore is ground t0 a fine mass and taken across the screens again. This is called a circulating load. From the screens, large bins or tanks con- taining water and flotation agents could be seen. The large ore-bins have a safety-device. If a man should fall into the bin, he could save himself by catching the cable, and so break a fall of forty feet. The small particles are so minute that they look like powder. From the bins the ore goes through tubes into six tube mills, six classi- ners and six notation cells which are called the primary cells. The ore is mixed with water and flotation agenits coming from the tanks mentioned above. The large particles o back to the tube mill, and the small ones are sent to another set of flotation cells, called the secondary cells. This is called a circulating load. The tailings from the pri- mary cells are checked on a vibrating table, and then taken into froth 'tanks and pumped outside. lFrom the secondary cells the floated material, sulphides and gold, is taken into two more tube mills which grind the mass down still finer and it is then ptunped into de-water filters. The de-water nlters extract all the water by means of vacuum pumps, leaving the dry caky metallics. Then the ore is taken through cyanide filters. The concentrates are taken to a bhickener which separates the heavy ores from the light ones: then they go through presses which extract all the lime. The solution then goes through a meter, which measures the amount going through. Zinc dust is added to precipitate the gold. Precipitation presses extract all the cyan- ide, leaving either the barren solution or the gold bullion which is taken to bullion fur- naces to be shaped into Gold Bricks which are sent to the Mint.
