If the lease made pursuant to court order, under section 2111.31 of the Revised Code is for the mining or removal of mineral or other substances on a royalty basis, within six months after the receipt of the first royalty under such lease the guardian shall report to the probate court the amount thereof and the court shall then fix a bond which will cover such royalty. At any time the court deems the bond insufficient to secure the royalty, it may increase such bond or require a new one.
