THE INDIA RUBBER WORLD

handling. The rubber compound is spread upon a sheet of thick, 

 soft felt The simpler forms, cut in a die press, are backed with 

 protective cloth and are ready for market. They are in two 

 shapes, round for corns and oval for bunions. A more modern 

 type has as an addition a strip of fabric, coated on one side with 

 rubber compound and placed over the toe in the felt plaster, 

 where it, together with the backing cloth, protects the dab of 

 paste that softens the corn, the rubber-coated circular felt pad 

 acting simply as a guard. In the manufacture of this type an 

 automatic machine cuts the strips, puts the dabs of paste in the 

 right place, sticks the felt pad just where it belongs, and finishes 

 by adding the strip of backing cloth. 



MOVING PICTURES OF BUSINESS RECORDS 



WH.\T we call the moving picture is not, properly speaking, 

 a moving picture at all. It is merely a sreies of pictures 

 each of which is seen at such a short interval after the pre- 

 ceding one that the image of one does not fade from the vision 

 before the next picture appears. It is this rapid succession that 

 gives the appearance of continuity and motion. The same pic- 

 tures when not seen in rapid succession do not give as vivid and 

 clear an impression. 



In much the same manner, data from business records, ar- 

 ranged in columns or tables and explained by text, does not 

 give the clear impression that it would if reduced to picture 

 form. If all the data can be connected in such a way as to give 

 the appearance of continuity, showing the relation of one item 

 to another, then practically the same result has been secured in 

 regard to business records that the motion picture secures in 

 regard to pictures. 



Various methods are now in -use for reducing business records 

 to picture form. Some are simple and some complicated. Some 

 serve their purpose admirably and some are deceptive. The 

 best of them blend the different data together in much the same 

 manner as the mo\-ing picture. They show exactly what is 

 going on, and whether the business is going ahead or behind. 

 A study of the pictured record shows what to do to increase 

 profits. There are many features of the business that show 

 up which would be overlooked without these records. 



These records serve their purpose in much the same manner 

 that a motion picture of a growing plant shows plant growth. 

 If one watches a flower grow, there are sure to be many details 

 of that growth which he either does not notice or fails to re- 

 member. However, suppose that at proper intervals a picture of 

 that plant is taken, the exposures extending over a period of 

 many weeks. When they have been completed and the picture 

 projected upon a screen, every detail of growth is seen. It is 

 the continuity that gives the motion picture its great value. 

 It is the continuity of properly made graphic charts, curves, 

 maps, etc., that gives them their value. 



Photographic moving pictures have served science and busi- 

 ness in many ways. For example, pictures are taken showing 

 the action of automobile and truck tires under various condi- 

 tions of load and road conditions. These are taken at as rapid 

 a rate as possible. They are then projected at a very much 

 slower rate and every detail of the motion and the action of 

 the tires at once becomes clear and vivid. 



Again, photographic records may be made of the motion of 

 machines, workmen, factory operations, anything that it is de- 

 sired to study. These can then be studied in far greater detail 

 than would be the case if attention was confined to the machines, 

 workmen, or factory operations. The motion picture gives a 

 record that is superior, so far as research is concerned, to the 

 actual thing or person studied. 



Curves, charts, etc., serve exactly the same purpose in the 



study of business records that the moving picture serves in study- 

 ing all tj'pes and kinds of motion. These give a continuous- 

 record of the growth of days, weeks, months or years in such, 

 form that trends, effects, causes, everything that affects the 

 business may be studied with detailed accuracy. Information is- 

 gained that could not possibly be gained in any other way. No 

 one could possibly study the same data in printed or writteni 

 form and be able to see as clearly the cause and effect, tlie trend 

 and the probable future results. 



The electric lighting business, which has grown from nothing 

 to a very large and a very important industry during the last 

 forty years, is an example of what picture records can accom- 

 plish. In this business question of rates was an exceedingly 

 important one. Unless the current could be sold at a suffi- 

 ciently low price it would not be possible to sell it. Cost of 

 production, market possibilities, and all other features bearing; 

 upon the proposition were reduced to picture records. These 

 were studied. New rates were established. Their effects were 

 studied by means of ne\v picture records. Those companies which. 

 made the greatest use of picture records have invariably been 

 the ones which have enjoyed the greatest degree of prosperity. 



Moving pictures of business records, that is, charts, curves, 

 maps, and the like, that show a continuity similar to that of the 

 photographic motion picture serve the business man as nothing 

 else can. They give accurate related data. Data that is unre- 

 lated does not always convey the correct impression. For 

 example, a table showing the cost of living and how it 

 has increased during the past few years may be decidedly mis- 

 leading Make a curve showing the change in the cost of living 

 during the past half century and on the same sheet draw another 

 curve showing average earnings of any particular class of people 

 and the result is accurate related data that tells the truth. It is 

 a moving picture that shows all the details in a manner that they 

 could not be shown by tables and descriptions, any more than 

 could the growth of a plant be pictured by tables and descrip- 

 tions as accurately as it could be by the motion picture. 



There is no other way in which the relation of cause to effect 

 can be shown with equal clearness. Make a graphic representa- 

 tion of the effect and also one of the causes and the relation 

 becomes transparently clear. As an example, make a picture of 

 commodity prices over any given period. Suppose it is made 

 from the period just preceding the Civil War up to the present 

 time. Also on the same sheet make a graphic representation 

 of the number of men killed in war, and the value of property 

 destroyed, the percentage of population in arms and the like. 

 The result is .\ perfectly clear representation of the relation of 

 war to the variation in the cost of commodities. Such a moving 

 picture will show what to expect during the coming years, as it 

 reveals the relation between cause and effect and the basic cause 

 of the present general price changes. 



Graphic records save an immense amount of time and make it 

 possible to secure data at a glance which would otherwise re- 

 •■juire wading through a great mass of statistics. They save 

 time in exactly the same way that moving pictures save time in 

 studying the growth of plant life. All this time saved is avail- 

 able fur planning bigger and better things in the future. It does 

 not have to be devoted to learning what has actually happened 

 in the past or what is happening at the present time. A single 

 glance gives most of this information. A few minutes of study 

 gives more information than hours of concentration could pos- 

 sibly give without these picture records, these graphic charts, 

 curves, maps, etc., that give true motion picture continuity to 

 business records. 



The Svensk.a Gai-oschforsaljnings Aktiebolaget, Stock- 

 holm, Sweden, wholesale dealer in rubber shoes, has increased its 

 capital to 180,000 kroner.
