fY1Y1TYYY,1mfTYYfiYYY me to count up the scores, if we have a-ny, and to tell what day and time we play. It helps me in playing handball by counting up points, and it helps me in all sports in making the places to play, as in handball I k-now how far back to put the short line and long line, and how wide to make it. In baseball, I know how big to make the bases and how far apart, and in basketball how high to put the basket and how large to make the basket and where to put the outside lines.- Ralph Beck. HOW ARITHMETIC HELPS ME IN SHOP Arithmetic helps me many ways in shop. We have to know how to read the ruler which we use so ofte-n. We also have to make out our lumber bills, and one mistake might make adifference in dollars. One must know how to'set the shop machine. There are many numbers on the machine, and you must be able to set them correctly. ln the tin shop we are now making cookie cutters, a-nd have a great deal of measuring to do. ln the print shop one must do much measuring. A beginning printer learns to measure and space with accuracy. These different steps in the job demand a sort of mathematical brain. Many slugs and leads are to be measured and cut for the many jobs. There is a cutting machine by which all paper is cut, and this must be done accurately. HOW MATHEMATICS HELPS ME IN MECHANICAL DRAWING Mathematics is the key to mechanical drawing, because if there were no mathematics we could not do any drawing. You must know mathematics to use the scales on the triangular ruler and to figure out the dimensions on blue prints and blocks. There is no way you can draw a projection drawing unless you have studied mathematics, because you have to figure out dimen- sions on 30 and 40 degree lines. A mechanical draftsman has to be a very good mathematician, because when he draws plans of buildings and houses, he does all the figuring of the plan, and one little mistake on the part of the man drawim-' the plan would be very costly, and sometimes very danger- ous.-Ernest Brooks. MATHEMATICS AS A HELP TO HOME ECONOMY Miss Noble: Those who can draw a draft, please stand. QAII girls stand but onel. Miss Noble: tsurprisedl Johanna, do you know where all of you learned to draw drafts? Johanna: ln mathematics, of course. Miss Noble: Mathematics comes in handy in sewing after all, fi!

L 1 YTYTYIYYWWVYYVYVY Punctuation Punctuation is very necessary, but many .people do not think so. You can tell that by listening to them read, or by reading their let- ters or themes. A sentence can have more than one meaningg all you -need to change is the punctuation. Probably the story of Mrs. Fiske and Miss Anglin ftwo of America's greatest actressesl can show you this. Mrs. Fiske went to call upon Miss Anglin, but found her out. So she left a note, which read, Mrs, Fiske says Miss Anglin is America's greatest actress. When Miss Anglin came back, she found the note, read it, then changed the punctuation, and sent it back to Mrs. Fiske as a com- pliment. This is how she changed it: Mrs Fiske, says Miss Anglin, is America's greatest actress. There is another story about two men who had a quarrel. One man called the other a liar. The insulted man said the offender ought to apologize for calling him that in public. After thinking it over, the man asked, How shall I apologize? Put it in the paper like this, said the so-called liar, I called you a liar, it is true, and I am sorry for it. The man agreed tol put it in just those words, but he punctuated it differently, so that it read thus: I called you a liar. It is true, and I am sorry for it. In all themes and letters you should be very careful in your punctu- ation, because punctuation comes next in importance to the correct spelling of words.--Compiled by Elma Hedberg, A8. The Story of My Life I fBy Math E. Maticsj When I was very little and started in the kindergatren, I was in the shape of colored papers and blocks that were placed on strings. Then I was promoted to the first grade in the form of One and One are Two, and things' of that sort. I tell you I was very puzzling to the little children. I-n the subtracting, multiplying, and dividing age, I was terrible, according to some peopIe's idea. As a fraction, the chil- dren wished I never lived. As a decimal I grew rich and poor by one turn of a pencil. In the Junior High School I was a trifle easier in the seventh grade, but I made up for it i-n the eighth. Then they. turned me into an alphabet-and of all the tests they made over me! But' I have led a useful life, as the following testimonials will tell: I ' ARI'I'l-IMETIC AS A HELPER IN PLAY Arithmetic helps me in my ball playing by finding the percentage of games we have won and lost, and my batting averages.

TYfTYYY1WifTYV'YfY doesn't iti All girls: Yes, uh-huh. I Miss Noble: fto girl who did not standj Why didn't you stand, Florence? Florence: The truth is, Miss Noble, I never have been taught to draw drafts. Miss Noble: Too bad! All these girls have learned to draw them, and can cut and make their princess slips with ease. Esther, will' you show Florence how to make a draft some day after school? Esther: Yes, Miss Noble. Miss Noble: Thank you, Esther, that's O. K. We shall now have some puzzle drafts. We will practice on a piece of material 16 inches lo-ng and 14 inches wide. Don't forget to leave six inches on the selvedge, and 2 inches from the bottom leave 2 inches more than that. Now, Esther, how are you going to cut? ' Esther: How long is the material down, Miss Noble? Miss Noble: You hnd that out for yourself. Take the yardstick and measure it. Now, how much isit? Esther: The width is 14 inches and the le-ngth 16 inches. Miss Noble: How much is that all around? You may do it on the blackboard. Before you do it, Esther, I want to ask a question. Estelle, how do you find the area of any square? Estelle: The length times the width. Miss Noble: All right. Now back to the begin-ning, Esther. How are you going to cut? Miss Noble: Correct. Now, Esther, how much is it all around? Esther: If it is measured from corner to corner it is 6X4 inches around. Esther: Let me see. The length of the material is 16 inches. I'll cut six inches from the selvedge for 14 inches, then the last two inches l'll cut eight inches from the selvedge. There now, it's done. Miss Noble: Very well done. You may take your seat now. Now, Florence, do you understand? Florence: Yes, ma'am, I understand now, and l'm sorry that I never learned drafting. Any way I never thought that it would help in sewing. Miss Noble: Yes, Florence, mathematics helps in nearly all sub- jects, and just where you think it won't help, is the place it does- Estelle Menacker, Johanna Kingry, and Esther Pressman.
