who had, by working at less than full pay, been kept out of the poorhouse; and the selectmen of some towns, notably Plymouth, have refused to obey such a vote. The California Code of 1906 provides a minimum compensation of two dollars per day for public labor, except as to persons regularly employed in public institutions. Delaware has copied the New York statute as to the prevailing rate. Hawaii, in public labor, provides a minimum wage of one dollar and twenty-five cents per day. Nebraska goes further, and provides not only for two dollars per day for public work, but that it must be done by union labor in cities of the first class, while Nevada has a minimum wage of three dollars and an eight-hour day for unskilled labor in public work. On the other hand, the Constitution of Louisiana prescribes that no law shall ever be passed fixing the price of manual labor.[1] [Footnote 1: This matter will be found further discussed in chap. XI.] Coming lastly to _tolls_, or rates of persons or corporations enjoying a franchise, that is to say, a legalized monopoly, or exclusive legislation, or special privilege, such as eminent domain, or the right to occupy the streets; such are, in fact, identical with what we term public-service corporations, the older, the most universal, and certainly the most, if not the only, justifiable example of legal regulation of the returns for the use of property or personal services. Whatever may be thought of the economic wisdom of attempting to regulate any rate or prices by law (and for a discussion of this subject as to railways, at least, the reader may well be referred to the valuable treatise of Mr. Hugo R. Meyer, "State Regulation of Railways"), such legislation was at least in England constitutional; but in this country, owing to our specific adoption of the principle of property rights and freedom of labor and hence of freedom of contract in our Federal and State constitutions, and as it has been repeatedly decided that to take away the income from property or a reasonable return for labor by legislation is to infringe on the property or liberty right itself, we have a universally recognized constitutional objection which has, in fact, made impossible all regulation of prices and wages, except as above mentioned, and as we are now about to discuss. The first attempt to regulate rates (with the possible exception of some early colonial laws) was the so-called Granger legislation, as shown in the Illinois Constitution of 1870, authorizing a warehouse commission to fix charges for elevating grain, the Act of Iowa of 1874 establishing reasonable maximum rates for railways, a similar act in Wisconsin of the same year relating to railroad, express, and telegraph companies, and in Minnesota; which legislation was all sustained by a divided opinion in the so-called Granger cases headed by Munn _v._ Illinois, 94 U.S. 113.
