Harrison Grant and Dixie Mason were in the vanguard of the forces which were detailed to resist the revitalized I.W.W. Both had a well definited theory as to where the unexpected wealth had come from, and knew that in meeting the agitation of the I.W.W. they were in reality working against another German plot in America. Raid after raid was made on local headquarters of the I.W.W. and many prisoners were made and hauled into court on charges of almost every felony on the docket, from murder down. Yet the organization continued to flourish. Outbreaks occurred all over America, some serious, others quelled almost before they were started. Grant and Dixie devoted their time to investigation and very seldom were engaged on a particular case when the time for raiding came. They discovered the plotters, an outline of the object toward which they were working, then turned the clearly defined trail over to other less skilled workers to pursue, while they gave attention to other fields which indicated a plot was brewing. Masses of documents teaching sabotage, destruction of all sorts, the making and firing of bombs, sedition and many other things detrimental to the industrial health and strength of a nation were the natural accompaniment of every raid. Sabotage was the most dangerous of all and it was to this branch of the I.W.W. activity to which Grant and Dixie devoted most of their time. Machinery in various plants suddenly broke down, despite the reliability of its manufacturers. Grant and Dixie discovered that emery powder had been mixed with lubricating oil, and as a result locks were placed on lubricating cups, and trusted men attended to the duties of oiling, using only oil that had been strained and inspected and kept under lock and key. There were epidemics of typhoid in colonies of workers and after their first investigation Grant and Dixie made a report which put every health officer in the country on guard against diverted sewage. Then came the fires in the wheatfields of the country. Grant and Dixie were already on their way to Minnesota when the announcement was made that their fields burst into flames under their own eyes, without another person being in sight. But Grant and Dixie did not accept this explanation. They knew that almost anything was possible where there was money to be obtained and they knew that Germany was supplying funds recklessly. Convinced that the fires were of incendiary origin, despite the testimony of the farmers, Grant and Dixie went directly to one of the devastated fields. There was nothing to be seen except acre after acre of charred soil where a few days earlier had stood bushels and bushels of wheat ready for harvest. The farmer pointed out to them the spot where the fire had started. Grant began an examination of the ground, while Dixie looked over the surrounding country. A railroad ran about a quarter of a mile distant. "It couldn't have been a spark from an engine?" she asked the farmer.
