Hough, J.
The present action is founded upon two bonds executed to the county of Lafayette by Wm. Hixon as principal, and M. L. He Motte and L. S. Hixon as sureties, one for $100, given for township school funds, the other for $819, given for school funds of the county. On the 13th day of June, 1871, Wm. Hixon, in pursuance of the requirements of the statute, executed to the county of Lafayette a mortgage securing both of the aforesaid bonds. On the 14th day of May, 1872, William Hixon gave another mortgage to secure said bonds, and an entry of satisfaction of the original mortgage was made by the county clerk on the margin of the record .thereof, bearing date May 14th, 1872.. When this entry was in fact made, does not appear. On the 10th day of July, 1873, Wm. Hixon presented a petition to the county court asking permission to substitute for the mortgages theretofore made by him, a mortgage upon certain real property described therein, which he represented as sufficient to secure the payment of the money loaned him; whereupon the county court made *582the following order: “It is therefore ordered that the clerk of this court enter satisfaction in full on said original-mortgages, upon the said Hixon presenting a mortgage on the above described real estate, properly executed;” and on the 11th day of July, 1873, Wm. Hixon executed and delivered to the county a mortgage on the property referred to in the foregoing order. An entry of satisfaction, without date, appears upon the margin of the record of the mortgage of May 14th, 1872, which we px’esume was made after the order of the 10th of July, 1873, but the recox’d contains no testimony on this subject. The mox’tgage of July 11th, 1873, recites an indebtedness of $1,569. This sum is lax’gely ixx excess of the sum due on the bonds sued on when the mortgage was given, and there is nothing in the record showing a reason for this discrepancy. As this mortgage, however, was offei’ed in evidence as havixxg been substituted, under the ox’der of the county court, for the mortgages made to secure the payment of the bonds ixx suit, we feel justified, in the px’esent defective state of the record, ixx px’esuming that it was intended to secure the bonds in suit and other loans. The sureties, De Motte and Hixon, pleaded and testified that the mortgages of June 13th, 1871, and May 14th, 1872, were enteréd satisfied without their knowledge or consent, and they claimed that they were, therefoi’e, discharged. The circuit court rendered judgment against the principal and in favor of the sureties. Fx’om this judgment the county has appealed.

The statute provides that when money belonging to the school ftmd shall be loaned, the county coux’t shall cause ^ same to be secured by a mortgage in fee on real estate situated within the county, free from all liens and incxxmbrances, and of the value of double the amount of the loan, and also with a bond axxd personal security. 2 Wag. Stat., 1258, 1259, §§ 81 to' 90. No authority is any whex’e eonfex’red upon the county coux’t to dispense with the real estate security required to be taken. The taking of such security is not a *583matter of discretion, but of positive statutory regulation. If the county court may take a mortgage and immediately thereafter release it, without payment of the debt it was taken to secure, and without taking in lieu thereof any other mortgage, it would seem to follow that the court might lawfully dispense with such mortgage in the first instance. So, also, might it in the same way dispense with the bond and personal security required to be taken. In this way the conditions and restrictions with which the Legislature has thought it prudent to guard the management of the school fund by the county court, might be disregarded and annulled. We see no reason, however, why one security may not be substituted for another, when the convenience of parties may require it and the change can be made without detriment to the school fund. And though such substitution should be made .without the knowledge of the surety, still, unless the surety were injured thereby, he would not be discharged. But if injured, he would be discharged to the extent, only, of such injury. If the mortgage taken by way of substitution be sufficient to pay the debt, the surety cannot complain of the substitution. Saline Co. v. Buie, 65 Mo. 63.
2. township parties.
There is nothing in the point that the county cannot sue on the bond given for the money of the township. In the case of State to use, &c., v. Sappington, 68 Mo. 454, it was expressly decided that the county may sue for the use and benefit of the township in such cases. The judgment of the circuit court will, therefore, be reversed and the cause remanded.
All concur.
Reversed.
