This is an action of ejectment for certain land in the city of Fayette, Missouri. The peti*529tion is in the usual form; the answer, a general denial, with an “equitable defense,” which is fully shown in the statement introductory to the report of the case. The new matter was denied by plaintiff’s reply. The cause was tried by the court. The substantial defendant is Mr. Eisher. His co-defendant, Mr. Senf, is his tenant in possession.
Both parties trace their claims of title to Mr. A. M. Fielding, who, in September, 1880, borrowed of Howard county $600 of the road and canal fund and gave a mortgage to'the county to secure his bond for that sum and interest, payable on or before December 31st of that year. The mortgage was duly acknowledged, and recorded shortly after its date. It provided that in default of payment of the bond, according to its tenor, “the then sheriff of said county shall have power to, and may, without suit on this deed of mortgage, proceed and sell the property herein conveyed and mortgaged, first giving twenty days’ public notice of the time, terms and place of sale, by publication in some newspaper printed and published in said county, if any such there may be; if not, then by six posted or written hand bills posted up at public places in said county, at . which sale the property shall be- sold to the highest bidder for cash in hand, and the said sheriff shall make an absolute conveyance in fee of the property thus sold to the purchaser or purchasers thereof, which shall be effectual to all intents and purposes as if such sale were made by virtue of a judgment of court of competent jurisdiction, foreclosing said mortgage.”
There was a default in meeting the bond and the property was advertised and sold according to the terms of the mortgage, June 11, ,1888. At that sale plaintiff bought the land for the sum of $567, and received a sheriff’s deed on which she now relies.
*530Before the sale by the sheriff the county court had made formal orders, first, reciting fully the facts of the loan and security; finding that default had been made; that Fielding was indebted to the county, for the use of the road and canal fund, in the sum of $529.33; directing judgment therefor, and that an order of sale of the property described in the mortgage should issue to satisfy the debt; second, commanding the sheriff of the county to levy the indebtedness, so found, upon the realty; to sell the same to Satisfy said debt and costs, and to make return of his proceedings under the order to the next term of court.
At the time designated he made return, reporting the sale to plaintiff for $567, and the conveyance to her after the required publication of notice, etc.
The sheriff’s deed to plaintiff recites the mortgage, its conditions and the power of sale as stated, the orders of the court, the facts showing his compliance with the terms of the power in respect of the giving of twenty days’published notice by advertisement, etc., that plaintiff was the highest and best bidder at the sale, and that the property was struck off to her; and then transfers and conveys to plaintiff all right, title and interest of the mortgagor t© the realty in question (to quote literally) “that I might sell as sheriff as aforesaid by virtue of aforesaid execution and notice,” etc.
It was properly acknowledged and recorded.
Defendants showed that there had been two entries ■on the margin of the record of the mortgage, purporting to release certain specified parts of the tract, upon two several partial payments on account of the debt .secured.
■ The land in suit is included in that mentioned in /'the entries of release, defendants having acquired Fielding’s title thereto after the making of those entries. *531One of the latter was signed by the county treasurer, and the other by the presiding judge of the county court. But neither purports to be based on any order of the court and it appeared affirmatively that no action of the court, authorizing any such release, had ever been taken.
The facts controlling the judgment are all conceded.
The trial court found for the plaintiff and entered judgment accordingly. Defendant appealed.
I. It is first insisted that the deed to plaintiff is of no force, because based on orders of the county court in the nature of a foreclosure which that court had no jurisdiction to make. Those orders were evidently designed to follow the procedure marked out for the enforcement of mortgages of school funds. Revised Statutes, 1889, secs. 8057-8059. But in the law governing the management of the road and canal fund, nothing is said as to the necessity or propriety of such orders.
By section 7782 (Revised Statutes, 1889, identical with Revised Statutes, 1879, sec. 6925) the county is authorized to loan such funds, “taking care in every instance to require good and ample security. ” No form is prescribed. The bond and mortgage in the case before us followed the form appropriate for school fund loans. It is evident that one of these ' blanks intended for those loans was used, after changing the recitals so as to apply it to the road and canal .fund, instead of to the school fund.
A grant of power is generally supposed to tacitly comprehend a grant of such incidental powers as may be necessary to make the principal grant effective. Broom’s Legal Maxims [8 Am. Ed.] pp. 479, 486.
The power to loan this fund and to “require good and ample security,” clearly implied the right to accept *532a mortgage on real estate as security for the loan. When it was executed, the property become subject to the terms and power of sale expressed in that instrument. Mann v. Best (1876), 62 Mo. 491; Grant v. Huston (1891), 105 Mo. 97. The county acquired thereby the right to resort to the security to realize the amount of the loan, to the extent, and in the manner defined in the mortgage. We need not consider whether or not the county' might have bought the land at the sale had it become necessary. That matter is now the subject of express legislation; but the latter was not in existence when the mortgage here in view was given, Revised Statutes, 1889, secs. 7788-7791.
As the land was sold to plaintiff, and the amount of the loan thus realized for the road and canal fund, the case, on this branch of inquiry, is simply whether the county could enforce its security, having taken it. Defendants stand in privity to the mortgagor. The sale actually made by the sheriff, under the express power vested in him, conformed strictly to the conditions prescribed for the exercise of that power. The county court had previously declared the debtor in default and directed the enforcement of the security.
It cannot affect the validity of the mortgage, or the rights conferred by its agreements, that the county court went further in its orders and undertook to follow the practice applicable to school loans, commanding a levy and special execution against the land, as well as ordering the sheriff to take the identical steps for the enforcement of the loan which the mortgage sanctioned. Those parts of the orders may be regarded as invalid without affecting the rights of the parties now before the court.
In the sheriff’s deed he referred his action to the notice (published in accordance with the terms of the mortgage, preliminary to the sale) as well as to the ‘ ‘exe*533cution,” as lie was pleased to term the order directing him to enforce the security for the county’s benefit. But his sale was plainly supportable under the mortgage and notice, and that is enough. The useful is not vitiated by the useless.
II. Next, it is claimed that the entries of release discharged the particular part of the mortgaged premises now in question from the lien of the incumbrance.
The court had control of the fund (Revised Statutes, 1889, sec. 7778), was authorized to make the loan and did so; but neither the treasurer nor the presiding judge, without authority from the court itself, could effectively release a part of the security on payment of part of the debt only. Nor could proof of a local custom to the contrary give defendant a greater right, or cut down the positive law in relation to a topic of this nature. Knox Co. v. Goggin (1891), 105 Mo. 182.
These entries we therefore hold were ineffectual to lessen the security of the county, or to release the land mentioned in them.
III. The “equitable defense,” so called, presents no equity. That plaintiff was informed that the releases, above discussed, were not valid; that the purchaser at the sheriff’s sale would not acquire a title to the land now in suit, or that Mr. Fielding told plaintiff that that land had been released, were facts which did not impair the force or effect of the security or diminish the estate or interest conveyed to the county, or to the plaintiff. There is no evidence whatever of any statement or act of plaintiff which would estop her from asserting her legal rights under the mortgage. She made no representation and did absolutely nothing, so far as this record shows, inducing any move on defendant’s part. She may have ‘thought her purchase' less extensive when made than it was in fact; but that furnishes no legal or equitable ground to deprive her of its full fruits.’
*534We see nothing substantial in the points advanced to sustain the appeal; and hence affirm the judgment.
