Our Readers' Service
Department
Since our editorial pages must he kept free from advertising matter of any kind, we cannot mention manufacturers' names, trademarks and the like. But if you want to know more about some simple tool or appliance which you can use in the shop or the home and which was described or illustrated in the Popular Science Monthly, if you want to know who can supply more information on a subject which has been discussed in our pages, write to our Readers' Service Department. Of the two hundred articles and three hundred pictures published each month by the Popular Science Monthly, there must be many that interest you in a personal way.
Even if the subject in which you are interested has not been taken up in the Popular Science Monthly, the Readers' Service Department will help you, either by giving you the actual information which yon want or by telling you from whom it can be obtained.
