There has existed at Goldfield, which is exclusively a mining town of an estimated population of between 15,000 and 20,000 in South Nevada, for over a year past, and especially since the spring of 1907, a disturbed industrial situation, due to frequently recurring labor difficulties between the mine operators on the one hand and the miners on the other. The two sides were represented almost completely by the Goldfield Mine Operators' Association, ... on the one hand and by the local union of the Western Federation of Miners on the other, a union comprising substantially all the miners in Goldfield. This union, known as Goldfield Miners' Union No. 220, is a branch of the general organization known as the Western Federation of Miners. It has carried on its rolls a membership estimated at above 3,000 men, which number, however, included members of crafts in Goldfield other than workers in and about mines. Figures furnished us by the mine operators showed that about 1,900 mine workers went on a strike on Nov. 27, 1907. Although a number of strikes and minor difficulties had occurred during 1907, the only acute situation arising prior to the call for troops existed in the spring of 1907. This controversy involved not only a dispute between the mine owners and the miners at Goldfield, but also between the members of the miners' union and the members of other crafts in Goldfield affiliated with the American Federation of Labor. The Goldfield Miners' union was also affiliated with the organization known as the Industrial Workers of the World, and an effort was made to force members of other crafts not affiliated with this organization to join its ranks. Not only the Mine Owners' Association and members of the miners' union went armed, but members of crafts not affiliated with the Industrial Workers of the World felt it necessary to carry arms to protect themselves while at work. The condition of Goldfield at that time was that of an armed camp, and for a time a serious clash seemed imminent. The controversy resulted in the murder of a restaurant keeper[361] and aroused such opposition against the Industrial Workers of the World that a ban was practically put upon them, and the organization under that name was forced to abandon Goldfield. This acute situation disappeared before the spring of 1907. A succession of miners' strikes, however, had taken place throughout 1907, some of them with apparently little justification; and although the operators had yielded to nearby all the demands of the union, it seemed impossible to secure any settled industrial conditions.
