The appellant, Thomas Evans, was indicted with George Rae for a violation of section 7193 of the Revised Statutes of Idaho, which, as amended by act of the fifteenth legislative assembly, reads: “It is unlawful for any person in this territory to make any dam, or use any nets, seines, fish-traps, or any similar device or measures for catching fish, or to ship the same out of this territory for speculative purposes.” The appellant, Evans, alone, was tried upon this charge, and from the judgment rendered against him upon his conviction thereof he has appealed to this court. While the record contains various specifications of alleged error, the appellant has in his argument of the cause referred to but two, viz.: That the statute does not prohibit the exportation of fish, and, if it does, it is in violation of section 8, article 1 of the constitution of the United States.
It is true the statute does not read as it undoubtedly was intended it should, and it is surprising that it passed unchallenged the ordeal of six readings in the presence of careful legislators. Construed as it reads, it prohibits the exportation from this territory only of dams, and the use of nets, fish-traps, and other devices for catching fish, and not the fish themselves. *660As dams cannot be shipped, and the use of a thing is an incorporeal right, this statute, if construed by its words, undertakes to prevent the performance of an impossibility, hence, in effect, is void. Conceding, however, that it may be construed to prohibit the exportation of fish, as the legislature undoubtedly designed it, is it in violation of the section referred to of the supreme law of the land? This question was involved in the court below, in the demurrer to the indictment, on the exceptions to the instructions, and in the motion for arrest of judgment, and is saved by appellant's exception to the ruling of the court in those matters. The provision of section 8, - article 1 of the constitution of the United States, that “Congress shall have power .... to regulate commerce with foreign nations and among the several states,” having been so frequently and fully considered by the ablest, including the highest courts in the nation, it will not be expected we shall, to any length, now attempt its discussion. It is clearly settled and conceded by all, that the above provision of the constitution confers upon Congress the exclusive power to regulate commerce between the states, and any statute which attempts to prohibit the shipment into or out of a state of any lawful commodities or articles of commence or trade is in conflict therewith, and necessarily void. To each state is reserved the power of regulating commence within its borders, but not that extending across its boundary lines. The state may also, under its police power, enact such laws as are necessary to the protection of the lives, the health and comfort of its citizens, and for the promotion of good order within its limits. But whenever, under the pretense of an exercise of its police power, the state enacts any statute which operates to prevent the free exchange between the states of lawful articles of trade, it is void because in conflict with that constitutional provision. This is clearly illustrated in a number of recent and interesting cases. Railroad Co. v. Husen, 95 U. S. 468, is a ease in which the state of Missouri, under the claim of exercising its police prerogative,’ and to prevent the spread of contagious cattle disease in the state, enacted a statute forbidding the unloading of Texas cattle within the state, but allowing their passage through it on board of ears or vessels. The court held that *661cattle were subjects of lawful commerce, and could not be excluded, except when diseased; that the statute practically operated, not in the exclusion of diseased cattle alone, but of all Texas cattle, and was void. The business of butchering cattle, and shipping the dressed fresh meat into the surrounding states from the place of slaughter, has in recent years become an important pursuit,' but one which came in conflict with local dealers. To prevent this, statutes were enacted in several of the western states, purporting to be in pursuance of their police power, and to promote the health of their inhabitants by preventing the importation of diseased meat. They required that all animals should be inspected within twenty-four hours before their slaughter, and the sale of meat of animals not so inspected should be prohibited. The courts have uniformly held that such statutes are not within the police power of the state, and that, whatever their design, they operate as a prohibition to the importation of dressed meat, which is a lawful article of trade, and whenever these statutes have come before the courts for consideration, they have been held void. The following eases on this subject will be found of interest, and in them the whole subject is fully reviewed: Swift v. Sutphin, 39 Fed. 630; In re Barber, 39 Fed. 641; In re Christian, 39 Fed. 636; Harvey v. Huffman, 39 Fed. 646; Ex parte Kieffer, 40 Fed. 400. In the state of Indiana a statute prohibiting the exportation of natural gas from the state through pipes has, upon the same principle, recently been held void. The state of Kansas has had a statute to prevent the shipment therefrom of fowls and other game. For a violation of this, an express agent was indicted for shipping to Chicago four prairie chickens. The act only prevented the exportation of chickens, and did not prevent their capture and use by the denizens of Kansas, but seemed rather to preserve them for their exclusive use and comfort. It was held void in State v. Saunders, 19 Kan. 128, 27 Am. Rep. 98. By the law of this territory we recognize fish as a lawful article of trade. The statute only attempts to preserve them for us, and to deprive our neighbors of their use, which, in the light of the authorities, we must conclude is in violation of the constitutional provision referred to, and therefore void. It follows that the demurrer to the *662indictment above referred to sbonld be sustained, and it is therefore ordered that the judgment appealed from be set aside, and the indictment dismissed.
