The Dakota Central Telephone Company is a corporation carrying on a long-distance telephone business in territory including the city of Milbank, S. D., and having a local exchange in -the city of Milbank. The Grant County Telephone Company has a local exchange a-t the city of Milbank. The local exchanges of these two companies not being connected, anti therefore subscribers of the latter company being required to resort to the ■exchange or some local phone of the first company in. order to send long-distance messages over its lines, this proceeding was initiated before the Board of Railroad 'Commissioners of this state to require the physical connection of the two exchanges, to the end that a- subscriber of the Grant County 'Company could, through the medium of the wires of such company, transmit and receive long-distance messages over the other company’s wires. After a hearing, the Board of Railroad1 Commissioners issued its order requiring" such connection to be made at the expense of the Grant County Company. From, such order the Dakota Central Company took an appeal to the oircu'it court, where a trial was had and findings of fact and judgment rendered; the judgment being a virtual affirmance of the order of the Board of Railroad Commissioners. From such judgment an appeal has been taken to this court.
[1] Appellant contends that the Board of Railroad Com*507missioners were without jurisdiction to grant any relief in this proceeding. It bases this contention upon the ground that this proceeding was not initiated 'by any telephone company, and that, under the express provisions of -the statutes of this state, such proceedings can only be initiated 'by a telephone company desiring •connection with another company. It is unnecessary and would serve no useful purpose to1 quote the various provisions of our statute, but from a consideration1 of the same we are led to the opinion that the Board of Railroad Commissioners has a right to act upon the complaint of any person or corporation having an interest in the relief sought, and that therefore this’ proceeding-was initiated by proper parties. To hold otherwise would destroy the efficiency of our statutes. When both companies desire connection, the power of the law is not needed. When neither company desires it, the public would be helpless. It would only be where one company seeks an advantage at the expense of the •other that .the power.of the state would be invoked.
[2] Appellant contends that the effect of making the connection ordered would be to deprive it of its property without due process of .law; that to require it to connect its local exchange with that of another company, and by so doing- give the patrons of such other company a right to' the use of its wires for long-distance service, is the exercise of the power of eminent domain; and that our Constitution prohibits the taking of property under such power without compensation therefor paid in advance. We are satisfied (that the connecting of telephone exchanges, in order to facilitate the transmission of messages, and therefore advance the purpose for which the public service franchises are granted, is not an exercise of the power of eminent domain, but is entirely analogous to .the power exercised by a Railroad Commission, in ordering connecting switches between competing- lines of railway; that, instead of being an exercise- of power of eminent domain, it is a mere regulation of a public service corporation, if not under an implied power resulting from the nature of the franchise enjoyed 'by. the corporation, then under the police powers of the state.

Ct. 115, 45 L. Ed. 194, affirming Jacobson’ *508v. Wis. M. & P. R. Co., 71 Minn. 519, 74 N. W. 893, 40 L. R. A. 389, 70 Am. St. Rep. 358; Notes, 50 L. R. A. (N. S.) 652-659.
[3] In discussing this contention the appellant has- laid great stress upon what it claims will be the necessary results flowing from the connection ordered, and argues (that, from the situation of these two companies — the comparative amount of local exchanges, etc. — the result of such connection will be to destroy the Dakota Central Company’s local business at Milbank. We are not convinced that appellant is correct in its conclusion, nor that such fact would be controlling herein-. In order to- arrive at such conclusion, appellant has assumed the -existence o-f many facts not stated by the findings1 herein, many of which this court could not take judicial notice of, being matters the peculiar -subject of expert knowledge. If it were desired to- urge such matters before this court, it wo-ukl have been well for appellant to have introduced- evidence to support -its- assertions-, and then to have procured proper findings o-f fac-t u-pon which to base its contention. The facts found by the trial court fully justify the judgment of such court.
[4] It will be seen that the' application was for connection so that the patrons of the local -exchange -of the Grant County Company could- h-arve the use o-f the- long -distance or toll system o-f -the Dakota Central -Company. The application filed herein did not seek a -connection making 'the exchanges intercommunicating so far as -the local business of such exchanges was concerned. Appellant contends that, if the connection .is ordered at all, it should be required to be such as to render the two exchanges intercommunicating for all purposes. From -the findings of fact made by the trial court it w-o-ul-d seem- that no good reason exists why such a connection should not he made; -but the evidence submitted, upon which these findings depend, w:as submitted upon the issues raised by the application and -answers herein. The Dakota Central Company did not seek the relief now prayed for, which they .might readily have done, either in th-e -original answer -or in an amended answer submitted in time, s-o that the other parties hereto might -have had opportunity to- offer -such testimony, if any, as woul-d be material under the changed issues. It is impossible for us to s-ay that facts could not and would not have -been shown to the Railroa-d Commissioners and to the circuit court such as would *509have justified such commission and such court in refusing the relief now sought by appellant. We do not think that this court would be justified in granting relief not sought under the pleadings herein, merely because the findings of fact upon which this appeal rests were such as would have justified the relief now sought, provided the parties were entitled thereto under their pleadings.
The judgment appealed from is therefore affirmed; but such judgment shall in no manner prejudice the righit of the appellant to apply to the Railroad Commission for the relief now sought in this court. To that end the appellant may, within 30 days from the date of the filing- of our remittitur in the trial court, apply to the Railroad Commission for an order allowing it to amend its answer herein, and through such amendment to seek such relief in the present proceeding, or, at its election, it may seek such relief at any (time in another proceeding.
