This effort to do away with the law of combinations in labor matters with that aimed at forbidding or controlling the injunction in labor disputes, and with also the statutes which give a special privilege to union labor, we have found to be among the most important pieces of modern legislation. Alabama and Colorado have statutes legalizing "picketing," but a similar bill in Massachusetts failed repeatedly of enactment. But when we come to the statutes applying to _combinations_ solely, and defining them, there have been many statutes declaring blacklisting and boycotts to be unlawful--which is merely the common law--and a few statutes especially forbidding them. Thus, by the year 1907, twenty-two States and the United States had statutes against blacklisting, five had statutes against boycotting, ten had adopted laws regulating strikes in cases of railway employment, Minnesota a law forbidding any employer to require as a condition of employment any statement as to the participation of the applicant in a strike for more than one year immediately preceding, Oklahoma a law requiring him to advise new applicants for employment of any labor dispute then pending with him, and to give such notice in his advertisements; which statute barely failed of enactment in Massachusetts. The best definition of the boycott is, perhaps, to be found in the law of Alabama: "Any two or more persons who conspire together for the purpose of preventing any person, persons, firm, or corporation from carrying on any lawful business, or for the purpose of interfering with the same, shall be guilty of a misdemeanor." The most cumbrous is that of Indiana, which, attempting to express the matter in more detail, is far too long to quote.[1] Many acts which are really part of a boycott, or unlawful, _i.e._, sympathetic strikes, will be found under the heading "Intimidation" or "Interference with Employment" in other States; such is the recent statute of Washington (see above, p. 251). Unless the function of a statute be to instruct the ignorant, it would probably be better to forego all such definitions and rely upon the elasticity of the common law. [Footnote: Indiana Revision of 1901, Sec. 3312 M. There is also an elaborate definition of "trusts," "conspiracies," and "boycotts" in chapter 94 of the Laws of Texas, 1903.] As an example of the most advanced labor legislation we may briefly digest the Oklahoma laws of 1907-8:
