It could not be expected that these new railroads would earn much, if anything, by way ofa return to those who would invest their money in theenterprise until the expected development of these new sources of wealth and com- merce should be realized; hence this exemption from taxation was pro- vided as an inducement for the investment. I therefore conclude that the exemption provided is a contract irrpealable under the constitution of the United States referred to. f It is insisted upon the part of the defendants that the eighth section of the charter does not embrace levee taxes, and, if it did mention them, that the levy of such taxes is an exercise of the police power of the state, which the legislature cannot contract away. I am unable to draw a dis- tinction between a tax to build and maintain a levee and a tax levied by a town or city for the purpose of building bridges, or making other im- provements for the benefit of the inhabitants of the town or city. And it is admitted by counsel for the defendants that the clause prohibiting towns and cities from imposing taxation on the company, its railroad, and other property connected with it, is a valid exemption. The char- ter provides an exemption from all taxation. ‘ ‘ The most difiicult point to be determined is as to the period of time at which the exemption commencesjwhether at the passage of the act or only from the time of the completion of the railroad or one of its branches to the Mississippi river. The act provides that the 20-years exemption shall extend for 20·years‘from the completion of the railroad to the Mississippi river, but not to extend beyond 25 years from the date of the approval of this act, after which time the property of the said rail- road might be taxed at the same .ra.te as other property in this state. It will "be observed that the eighth section of the act under which the ex- emption is given tixes no point on the Mississippi river. The-second section of the act provides that one of the lines, or a branch therefrom, shall reach the Mississippi river at or ·near a point opposite Arkansas City, if practicable, but this provision relates only to the practicability of reaching the Mississippi river at or nearly opposite Arkansas City. Thecompletion of the railroad to any point on thisriver will entitle the complainant corporation to the exemption provided, but it must be com- pleted to some point on this river to entitle it to the 20- years exemption. When that is done, the exemption will extend to all the railroads, and · property connected with it, used in their construction and operation un- der the charter, including its stock. It is argued by the learned counsel for the complainant, with great earnestness and plausibility, that the
