It appears from this record that Carlos Bean in 1927, being then in the United States Navy, and stationed at Washington, D. ti., executed and delivered to his brother, Nat B. Bean, the following power of attorney:

A few days after the above power of attorney was delivered to Nat Bean, a suit for partition of the lands described in the power of attorney was filed in the district court of Busk county by owners of certain interest in the land, and Nat Bean and Carlos Bean were made defendants in that suit. A final judgment of partition was entered in 'the partition suit on the 9th day of January, 1929, and the decree as entered set apart to Nat Bean and Carlos Bean jointly what is known as a 59-acre tract of land, a part of the Isaac Bud-die and Jacob Lewis surveys in Busk county. And it is the title to the mineral estate in this tract of land that is involved in this appeal. The 59-acre tract, according to a recent survey, was found to actually contain 64.54 acres.
On October 16, 1930, Nat Bean for himself individually, and as attorney in fact under the above power of attorney for Carlos Bean, executed to Prank Elder an oil and gas lease for a period of ten years, and for a consideration of $3 per acre cash. The lease contained the many usual provisions found in such instruments. On January 31, 1931, a correction lease was executed to Prank Elder by Nat Bean, and which he also signed as attorney in fact for Mary Bean, the wife of Carlos Bean, from whom he had no power of attorney. This lease was assigned to various individuals, all of whom are parties to this suit. Nat Bean'also executed a mineral deed to J. W. Barton for a one-fourth interest in the minerals in the tract of land, signing the •same individually and as attorney in fact for Carlos Bean. Those claiming an interest to the minerals by virtue of this deed are also parties to this suit.
This suit is by Carlos Bean in trespass to try title against Nat Bean and the other parties who claim the interest of Carlos Bean in the minerals of the land involved by virtue of the conveyances of Nat Bean as attorney in fact for Carlos Bean. In his petition Carlos Bean also seeks an accounting from the defendants for the oil taken from the land. The several defendants answered by general demurrer, general denial, pleas of not guilty, and some of them claim to be innocent purchasers for value, and certain others who have developed the property for oil set up im*654provements in good faitli and seek to recover the value of same in the event the plaintiff ■ should be successful in recovering the title to the respective interests claimed by them. The case was tried before the court without a jury and resulted in judgment for the plaintiff, Carlos Bean, for a 42½ per cent, interest in the land involved and adjusted the equities between the parties with reference to the improvements placed upon the land. From this judgment the defendants have prosecuted an appeal to this court.
The appeal presents for determination the controlling and all-important proposition of law as to whether or not the power of attorney executed by Garlos Bean to Nat Bean had the legal effect of authorizing Nat Bean to sell and convey the mineral estate which the appellants claim.
. In determining this question we have reviewed many authorities with respect to the rules which should govern courts in construing the legal-effect of a power of attorney where such powers-are required, as here, to be in writing, a few of which we will briefly refer to.
To begin with, there is a general rule universally applied by the courts of various jurisdictions that all powers conferred upon 'an agent by a formal instrument are to receive a strict interpretation, and the authority is never extended by intendment or construction beyond that which is given in terms or is necessary for carrying the authority into effect,- and that authority must be strictly pursued. Frost v. Erath Cattle Co., 81 Tex. 505, 17 S. W. 52, 26 Am. St. Rep. 831; Skaggs v. Murchison, 63 Tex. 348, 353; Gouldy v. Metcalf, 75 Tex. 455, 12 S. W. 830, 16 Am. St. Rep. 912; Reese v. Medlock, 27 Tex. 120, 84 Am. Dec. 611; McAlpin v. Cassidy, 17 Tex. 449; Meador v. Wagner (Tex. Civ. App.) 70 S.W.(2d) 794; and authorities therein cited.
The purpose for which an authority is given is to be ascertained from the words or language used by the parties in the instrument conferring the authority. Reese v. Med-lock, supra. And under no circumstances can the principal toe bound beyond the plain import of the language of the instrument. Henry v. Lane (C. C. A.) 128 F. 243; Skaggs v. Murchison, supra. The words used in the instrument construed will be given their commonly understood, everyday meaning. Wynne v. Parke, 89 Tex. 413, 34 S. W. 997.
With the foregoing rules of construction as our guide, we have reached the conclusion that the power of attorney under consideration, as a matter of law, did not authorize Nat" Bean to sell and convey by lease or deed the minerals under the land. The language of the instrument construed most favorably to the appellants grants only a naked power of sale of land, and such power does not include the right to lease it. 2 C. X § 290, p. 646. The very question here involved as to whether the power to .sell land authorized the agent to execute a mineral lease on the same was before the Louisiana Supreme Court in the recent case of Bolton v. Rouss, 144 La. 134, 80 So. 226, and it was there held that the agent had no such power. The Supreme Court of Louisiana is the only court, so far as our investigation discloses, that has had the precise question before it; but the point, to our mind, is in all respects analogous to the situation of one who, having the power to sell the land; conveys instead only the timber on the land; and it has been held that such a power confers no authority for the sale of the timber. St. Louis S. W. R. Co. v. Bramlette (Tex. Civ. App.) 35 S. W. 25; 2 C. J., § 249, p. 613; 1 Clark c% Sayles Law of Agency, § 235, subsec. hi, p. 552.
It is insisted by appellants that an oil and gas lease or deed to the minerals in land in Texas is a conveyance of a distinct portion of the realty, and for that reason a power to sell and convey the fee-simple title to the land should include the power to sell and convey the minerals separate and apart from the land itself. It is true that our courts have held the legal effect of a conveyance of the minerals is to convey a distinct portion of the •land ; but this construction, in our opinion, is of no importance in ascertaining the intention of the parties to the instrument to toe construed. We are concerned only with the .gathering of the intention of the parties from the language used as understood in common, everyday parlance; and surely to the average owner of real estate a right to sell the land does not carry with it the right to sell the minerals separate and apart from the land itself.
We have reviewed the authorities cited by appellants and relied upon as supporting their contention that the power of attorney did authorize the sale and lease of the minerals separately from the land as a whole, but we do not believe they are applicable to the situation presented by the power of attorney under consideration.,
Finding no error in the record, the judgment of ihe trial court will be in all things affirmed.
