“There are very large firms throughout the country whose sole business is for this line of merchandise, and who are at all times anxious to make contracts with parties in the countr y who will give the work business-like attention, such as would attend the production of other farm articles, and which is so necessar y to the success of the work. If one could visit the buyers of such firms and ask how reliable they have found their sources of supply for the various kinds required, it would provoke much laughter. It is quite true that not more than one in one hundred who write these firms to get an order for some one or more kinds they might supply, ever give it sufficient attention to enable a first shipment to be made. Repeated experiences of this kind have made the average buyer very promptly commit to the nearest waste basket all letters received from those who have not been doing this work in the past, recognizing the utter waste of time in corresponding with those who so far have shown no interest in the work.”
