Have You a Clear Understanding of the Alany Uses to 

 Which the Comptometer is Being Put ? 



FOR PAY-ROLL AND COST-KEEPING accounts, tlie Comptometer, once 

 used, becomes indispensable. It has no sutistitute. liut that is oidy a part of it. On 

 trial balances, or any other kind of adding, it turns out the work witli absolute accuracy 

 and so easily and rapidly as to pay for itself several times a year. Then there is the 

 multipljing and dividing. To those who have used the Comptometer on multiplication or 

 division, from the simplest bill extensions and checking to the large computations involved 

 in railroad accounting, the mental process by comparison seems absurd and foolish. 

 They wonder why anyone would waste time and useless pain by pursuing the old, slow, 

 uncertain, and nerve-rackinj; methods. 



You could use the Comptometer and though not a mere toy it does not cost too much. 

 Light to carry, small and convenient to set on a book or desk. 



WITH MULTIPLICATION OF ANY KIND it cuts the time of the most 

 expert mental computer two thirds ; makes hard work a pleasure, and insures accuracy 

 beyond the possibilities of any other known method. So simple and easy that a child can 

 learn to multiply accurately and rapidly in ten minutes. From extending or checking bills 

 of any kind — fractions and all — to computing railroad tonnage, there is absolutely nothing 

 that can compare with it. 



It will save you money ; also worry. It really does the work. All you have to do is 

 simply touch the keys and read the answer ; and you touch them in bunches ; two, three, 

 four at a stroke, and the answer will be correct just the same. Nothing else like it in all 

 the world. It will do all your adding, multijilying and dividing in a mere fraction of 

 the time it takes to do it mentally, and so easily and surely that you will wonder whv 

 you did not look into it before. The only ma:;hine that is rapid on all classes of adding 

 and calculating, and it is more rapid than any other on any class of work. Thousands of 

 our customers started with one machine who to-day use from 2 to 100. WHY DID 



THEY BUY MORE ? 



A GOOD CALCULATING MACHINE gives better satisfaction and saves 

 more money than almost any other modern invention. Saves overtime and headaches, too. 

 The best is not necessarily the most expensive, neither is it a toy. 



The Western Electric Co., New York, writes : — " We have over 20 Comptometers in use in 

 our ditt'ereut houses. We have experiniented with most all the adding and multiplying machines on 

 the market, and have come to the conclusion that for all-around work the Comptometer is the best." 



The Hartford Fire Insurance Co., which uses six Comptometers, writes : — " Most of our 

 work reijuires results only, and for this purpose we find no other machine as reliable and rapid as the 

 Comptometer. We use in om' banking department a 375.00 dollar adding and listing machine. We 

 make use of this only where a list is required." 



Meyer Bros.' Drug Co., St. Louis, Alo., writes: — "We use the Comptometer exclusively 

 in our billing department : wjiilst we have other adding machines in different departments, ninety 

 per cent, of our addition-^ are made on the Comptometer. A great time saver, executing work 

 accurately and ijromptlv."
