The genial Mr. Vebeck pictured above, has been in the Comptometer organization since 'way back in 1905.

During all these years he has been compiling methods for problems sent in from the field, and amplifying these thousands of ways of doing any and all kinds of figuring on the Comptometer.

''If you have any problem that's puzzling you, send it along. (I'd like to see him stumped.—Ed.)''

HE Ed. knows well enough that the party pictured so nicely doesn't know every short cut or how to do every figure problem presented, but after handling the Operating Instruction Department for about 20 years, a great many short cuts and methods have been learned and worked out, so that he is able to assist on about every kind of figuring imaginable. Right now the Correspondence Operating Instruction Service Department is instructing by mail over 400 operators, and so far this month (November), 92 operators have written special thanks for the operating help given them.

Even though you know how to add, multiply, divide and subtract on the Comptometer, you may be still in kindergarten as far as efficient Comptometer operation is concerned. Even with the volume of information available here, there is yet much to learn about Comptometer application and short cuts, so just imagine what some operators don't know about Comptometer application. We would like to suggest as a good idea, that every operator procure one of the Correspondence Instruction Service Sheets which gives about 50 Comptometer uses, and then check it to see with how many of these uses they are familiar. Of course, even the uses on this Instruction Service Sheet are just an inkling of the figure work for which the Comptometer is used.

Do you know how to subtract on the Comptometer, February 4th, 1925, from November 8th, 1926, almost as easily as you can subtract $5.25 from $6.50—or how to multiply 47$1/2$ x 193$3/4$ and from that subtract 67.3 x 17$1/3$ and get the answer without writing any figures down on paper and without cancelling―or how to subtract an amount that's already in the machine from any other amount without first clearing the register―or how many figures of the divisor it is necessary to hold if you divide, for instance, 483621. into 2164835. so as to get three decimal places of accuracy―or do you know how to figure percent of profit by just making one division and not finding dollars profit―or how  (Cont'd on page 12)
