HOW TO MAKE.A MODEL GRAIN ELEVATOR. John Messer, better known among the boys as Jack Kneiff, (pronounded Jack- ), was proudly happy. For years he had been working at as education with sc¢hool, college and travel &y a basis and some hard knocks since in getting started In the world; but at Jast be had come into his own, and was scttied In a most unique position enda orie he never dreamed of occupying, even when he left college. n, or Jack, as we shall call him, was always Interested In boys and in making things, and soms way he Dever could § &ive up that hobby of his of getting the boys sbout him once in a and telling them how to make ingenious toy or model machine he contrived, until he had several boys, with whom he met or hom he wrots ebout his new,ideas n time to time. it was his work, and Jsek it work—he so thor- of - But now smiled at calling oughiy enjoyed it On a certain memorable trip to Metrop- & fow weeks before he had made ances on the train to whom, chance drawing, he had vs end his habit to make things. some acqua it chanced, was promi- n the newspaper world of Metropolls us it was that Jack now stood n workshop satisfied with know- was to write and draw up the boys every for thely amuse- while he would be machine for and instruction the boys themselves in able to meec his shop after school hours and help them about things they weres making or in the selection of tools—in fact, every- thing pertaining to making things, is shop was fixed up mainly for his k, experimenting and working things he got up for the boys. had several extra manual tramn- ing benches 0o in the shop for the e when he was showing them contrivance which they wanted to work out right away. in en adjoining room Jack had his office with the usual office turmiture, & drawing table, and typewriter, and here i was he worked out the ideas begun in his shop and got them into shaps by drswing end writing for publication in the papers every week. The newspaper offices were in the same bullding. A friend of Jack’s came into his office the first day after he had opened i up to congratulate him on his success. Jack wag et the typewriter when he came in but arose and came forward, greeting him with a friendly handclasp. “What's up now? asked the new- comer. ““What kind of & scheme is this?” he continued, his eye eatching sight of e large drawing near Jack. “Oh, that's my stunt for next week, A miniature grain elevator.”” “A grain glsvator?” eghoed the lother, © 7 Traucisco Sunday Call “Looks good In the drawing, it kind of hard to make?” “Not half as hard as it looks.” There isn’t anything used in making it that can. not be picked up around any house, and there’s no fine fitting to be done, so, al- together it's an easy thing to make.” “But what does it o7 Jack yowuted to the picture at the bot- tom of the page. “Here,” he sai@ “Is the whole works, with the drawings at the top there to help out. “You see first there’s a frame, sort of box shaped. made of two side pleves A with pieces ¥ at the ends. A cigar box set on end would make a good frame for this if you were making a small one.’ “One of the ends, the one on the right hand in this drawing, Is cut off a little short and from fhere three thin wooden pieces fitting inside the box at G, (a), and (e), form a sort of Z-shaped frame, a lit- tie space being left between the end pisce F and the slanting plece G. “Down in the trough-shaped part be- tween (a) and G a spool S is mounted on en axle (5) and another spool is mounted just above where (¢) and (a) join. This 8pool you see too at S above. “Then we run a belt between the two spools with Jittle tin buckets on and then if we pour the grain in at the hopper formed by G it will go down sround the spool 8 fn the trough so when we turn a crank that will turn the shaft (s), the buckets on the revolving beit will scoop up the grain, carry it up and dump it into the bin above The other was interested. “It doesn’t look very hard” he sald. “How do you make the belit and buckle part though and how are the spools fast- ened on?” “That's easy. You drive a tight wood- en shaft through the hole in the spool, this shaft being long enough so it will just fit nicely inside the box crosswise, between the sides A. “You punch brad awl holes in the -side of the box at the place you want the spools to be mounted gnd then through thess holes you drive small brads or needles into the wooden axles you put in the spool, being careful that they go just In the middle. ““T'he bottom spool has the shaft left Jong on one cnd running through a hole in the side of the box part; the other short end has a brad or needle bearing the same as the upper spool. Then out- side a crank is fastened to the shaft () o turn the lower spool. In the drawing up ebove T have shown it fixed with a Iittle wheel or pulley P with a cranked bandle fastened to it et H. In this way if you have a little metor, water motor, or steam engine, or somcthing of the kxind, you can run & belt around this pulley and then you won’t need to turn the crank by hand but can work your elevator from the power of your water metor. “The belt B is just some ordinary cot- ton tape such as your mother uses for sewing. If you are making a larger ele- vator you can get a military brald up to several inches in width which will an- swer the purpose, but, of course, then you would have to use some gther kind of roliers instead of spools at S. “l am taking it for granted that the boys will use this narrowey tape and so I am giving my description accordingly. but isn't KKR s — DSSNS N o oS N NS S S EI P~ TSt ._;‘:\\\ A o Z ZZ ZZ AN =2 SRR Do O 7 NS N N S SSSTR VA S SN NS N ST AN N R}\}\\\\ e N N S > AN NS N N SR Moo \O S it stretches, it may be tightened enouzh the upper one—has & shoitar shaft and or oats, or the liki, for your elevator, and (¢).

Middle-Aged Man Emancipated From the Thrall of Petty Things. *“I find.,” said the middle-aged man, that I am now, in writing, more and mere inclined to leave the dots off my I's and the crosses off my t's. “Once, when I was myself more precise, such omissiong seemed to me to indicats slovenliness or undue haste on the part of a writer, and so they might reveal & lack of proper consileration for the per- son addressed; but now when I find that I am myself falling into such ways X have a feeling of greater lenfency toward those whom I once thought offending. “Now it no longer seems to me thal failure to dot our I's and cross one's t's indicates carelessness or indifference; it may show simply an effort to save time on the part of a writer hurried, or & philosophical desire to avold the wasts of time, the most valuabla of all things to us, and the only thing that is allotted tq all men without regard to worth or ca- pacity, in absolutely equal and Inallen- able shares. “Ang so now, If T get from & friend & fetter without all the ,I's and t's duly dotted and crossed. it may not Indicate that he is careless himself. or thoughtless of me, but that he values time and trusts me not to be offended that he Writes o me in his accustomed way. “As grow older time, which We so thoughtlessly waste In our youth, Dbe- comeg more and more precious to us. Fortunately for us, however, we neves realize how little of it we now have left, else we ghould worry over that, and s, 48 we grow older—if blessed with good heaith—we fiud more and more joy & existence. “So it is in my growing years and keener knowledge of the value of time that I find one reasom for my dropping my dots and crosses, but I am Inciined to think, after ail, that the controlling rea~ zon for this lies in our common later life tendency to make less of detalls. As we grow older we comae to discover that prin- ciples are the things, not the milllon petty details. “In youth, withgour narrow vision, ail details are fmpofant to us, and they may seem all important: their punctilious observance may then constitute for us our main duty, but as we grow oider and take a broader view we are lkaly to smile and perhaps to wonder over the time we wasted and the worries we once Save ourselves over innumerable things that seemed to us of importance. but thax really wers of no account at all. As we grow older we gain that great advastage in life—a freedom and power likely to come to us only as the result of observa- tion and experience—an gbllity to get along without worrying over triffes, ~And so I am inclined to think that It is neot so mueh the seving of time thereby as it is this later life emancipation from the thraldom of petty things that moves me now in my manner of writing. I am not less careful of the substance; I think, indeed, that 1 am now more thoughtful of that and more thoughtful as well of mak- ing my meaning clear and even my Writ- ing plain and easy to read, but I no long-~ er worry as I once did about the dots and crosses.”—New York Sun.
