Mr. Wilson is president of the bank through which the `` Harding System '' transacts most of its financial operations . `` You can do me a favour , if you will , Smith , '' he said . `` I shall stay over night in Oak Cliff . We have visitors coming to Woodvale to-morrow evening , and I should be back here to dine with them by six o'clock . There is no train from Oak Cliff within hours of that time , and it has occurred to me that the folks might come for me in the red machine . Of course the Kid thinks she can handle it , but I hate to trust her on so long and hilly a route . Could you come with them ? ''
