“We do not desire to be understood by this decision as approving of the broad proposition that private property may be taken in all cases where the taking may promote the public interest and tend to develop the natural resources of the state. We simply say that in this particular case, and upon the facts stated in the findings of the court, and having reference to the conditions already stated, we are of the opinion that the use is a public one, although the taking of the right of way is for the purpose simply of thereby obtaining the water for an individual, where it is absolutely necessary to enable him to make any use whatever of his land, and which will be valuable and fertile only if water can be obtained.” Again, in the very recent case of _Hairston_ v. _Danville & Western Railway Co._, 208 U. S. 598, the facts were that the Supreme Court of Virginia had sustained a proceeding by which a railroad condemned land for a spur track to a tobacco factory, the owner of which agreed to reimburse the company for the cost of acquiring the land. The decision of the federal court sustaining the judgment of the state court was delivered by Mr. Justice Moody, who said: “When we come to inquire what are public uses for which the right of compulsory taking may be employed, and what are private uses for which the right is forbidden, we find no agreement, either in reasoning or conclusion. The one and only principle in which all courts seem to agree is that the nature of the uses, whether public or private, is ultimately a judicial question. The determination of this question by the courts has been influenced in the different states by considerations touching the resources, the capacity of the soil, the relative importance of industries to the general public welfare, and the long-established methods and habits of the people. In all these respects, conditions vary so much in the states and territories of the Union that different results might well be expected.... No case is recalled where this court has condemned as a violation of the Fourteenth Amendment a taking upheld by the state court as a taking for public uses in conformity with its laws.... We must not be understood as saying that cases may not arise where this court would decline to follow the state courts in their determination of the uses for which land could be taken by the right of eminent domain. The cases cited, however, show how greatly we have deferred to the opinions of the state courts on this subject, which so closely concerns the welfare of their people. We have found nothing in the Federal Constitution which prevents the condemnation by one person for his individual use of a right of way over the land of another for the construction of an irrigation ditch; of a right of way over the land of another for an aerial bucket line; or of the right to flow the land of another by the erection of a dam.
