In 1901 there are four statutes, that of Minnesota also including a prohibition of boycotts, and the first piece of legislation upon the subject in the old Commonwealth of Massachusetts--an ordinary statute against exclusive dealing; that is to say, the making it a condition of the sale of goods that the purchaser shall not sell or deal in the goods of any other person. In 1902 both the Georgia and Texas laws were declared unconstitutional because they exempted agricultural pursuits. South Carolina has a statute actually prohibiting any sale at less than the cost of manufacture, doubtless also unconstitutional. In Ohio corporations are forbidden to own stock in competing companies. The Illinois anti-trust act was declared unconstitutional in 1903, while Texas amended its statute to meet the constitutional objection, and followed South Carolina in prohibiting the sale of goods at less than cost. In 1904 there is no anti-trust legislation. In 1905 the South Carolina law is held unconstitutional, and in 1906, that of Montana. In 1907, however, under the Roosevelt administration, there was a decided revival of interest, seventeen States adopting new statutes or amendments, but still I can find no new principles. Kansas copies the Massachusetts statute, and Massachusetts extends it to the sale or lease of machinery or tools. Minnesota and North Carolina have interesting statutes prohibiting discrimination between localities in the sale of any commodity. Most of the States by this time have statutes compelling persons to give testimony in litigation about trusts and exempting them from prosecution therefor. North Dakota has also a statute prohibiting unfair competition and discrimination as against localities, while Tennessee makes it a misdemeanor to sell any article below cost or to give it away for the purpose of destroying competition. In 1908 Louisiana and Mississippi adopted the principle forbidding discrimination against localities, and the new State of Oklahoma comes into line with the usual drastic anti-trust statute, and we may, perhaps, conclude this review of a somewhat unintelligent legislative history by perhaps the most amusing example of all. The Commonwealth of Massachusetts, which had so far refrained from unnecessary legislation on this great question, thought it necessary to adopt a statute making void contracts to create monopolies in restraint of trade, which well shows the necessity of a legislative reference bureau or professional draftsman, as discussed in a later chapter. That is to say, it says literally: "Every contract, etc., in violation of the common law ... is hereby declared to be against public policy, illegal, and void." As the law of Massachusetts is the common law, and always has been the common law, this amounts to saying that a contract which has always been void in Massachusetts is now declared to be void. But, moreover, on a familiar principle of
