The plaintiff, respondent Great Salt Lake Authority, seeks to take by proceedings in eminent domain the property of the defendant, appellant, on the north end of Antelope Island. Defendant moved to dismiss the complaint which motion was denied. The defendant’s petition for an interlocutory appeal was granted. An opinion was filed June 2, 1966, which appears in 18 Utah 2d 45, 414 P.2d 963. A rehearing was granted and the case resubmitted. Plereafter we shall refer to the parties as plaintiff and defendant.
The Great Salt Lake Authority was created and derives whatever power it has from Chapter 161, S.L.U.1963 (now Chapter 8 of Title 65, U.C.A.1953). The defendant contends that the act is invalid because 1) : It fails to prescribe definite limits to plaintiff’s territorial boundaries; and 2) : That it contains an unlawful delegation of legislative power; and 3) : That in any event it does not grant plaintiff authority to take defendant’s property by eminent domain.
The defendant in its first contention claims that the act does not delineate the limits of the territory over which the plaintiff shall have authority to act. Sections 1 and 6 refer to “development of the Great Salt Lake and its environs.” The title to the act makes reference to the “Meander Line Established by the United States Surveyor General,” but the title is not a part of the act. We are inclined to the view that the legislature by the use of the words “and its environs” created an uncertainty in failing to spell out the area over which the plaintiff was to exercise its functions and by reason thereof the act is invalid.1
The defendant’s second objection to the statute is that it contains no definite standards or limitations on the authority granted and is an unlawful delegation of legislative authority. The act makes several references to the accomplishment of objectives and purposes set out in this act; but the act does not define what the objectives and purposes are. The only section of the statute 2 which attempts to set out objectives is as follows:
“The authority shall co-ordinate multiple use of property for such purposes as grazing, fish and game, mining and mineral removal, development and utilization of water and other natural resources, industrial, and other uses in addition to *278recreational development, and adopt such reasonable rules and regulations as the authority may deem advisable to insure the accomplishment of the objectives and purposes of this act.”
A careful reading of the act in its entirety fails to disclose any limitation on the power granted to the plaintiff. It is also observed that the act fails to identify with any degree of clarity the powers, duties and responsibilities of the plaintiff.3
It is the defendant’s third contention that the act does grant to the plaintiff the right to take defendant’s property by eminent domain. It is noted that Section 65-8-6 of the act provides as follows:
“The authority shall have power to construct facilities and to acquire real and personal property in the name of the authority by all legal and proper means, including purchases, gifts, devise, eminent domain, lease, exchange, or otherwise.”
The last paragraph of the same section which deals specifically with Antelope Island provides as follows:
“The authority is authorized to take any steps that are necessary to secure such part of Antelope Island by donation, purchase agreement, lease, or other lawful means as deemed necessary for recreational use.”
It will be observed that the legislature in speaking of the property we are concerned with failed to include as a means of acquisition the taking by eminent domain. We must assume that the legislature intended that language, otherwise it may well have omitted the above quote provision altogether. We must conclude that the legislature intended a manner of acquisition of Antelope Island other than eminent domain. We conclude that the plaintiff was not empowered by the act to bring these proceedings.4
It is directed that the complaint be dismissed. No costs awarded.
