The respondents commenced an action in said Circuit Court to recover the sum of two thousand five hundred dollars which they alleged to be due from the appellant, as executrix of the estate of Charles Hodge, deceased, and which allegation was controverted by the appellant. The case was tried before the Circuit Court without a jury, and judgment given in favor of the respondents for said sum. The ’ only questions in the case that need be considered ai’e the rights and liabilities of the parties under an agreement of assignment of a half interest in a lease, made by the respondents to said Charles Hodge in his lifetime, and the sufficiency of the findings of the Circuit Court to sustain the judgment given thereon. Some other questions were raised by the appellant’s counsel, but the court regards them as untenable. The agreement of assignment is as follows: —
“ Mem. of agreement made between Reuben Doty and J. H. Ray of the first part, and Charles Hodge of the second part, witnesseth, that the parties of the first part, in consideration of one dollar U. S. gold coin to them paid, and for the considerations hereinafter mentioned, have agreed and do hereby agree to transfer, assign, and make over unto the party of the second part, one-half interest in a certain lease and agreement made between the Bonanza Gold and Quicksilver Mining Company and John Winterburn and Imes J. Napier, dated October 1, 1881. The consideration noted in the margin to be paid by the said second party to the said first parties.

“(Note in margin.) $750 cash, $1,250 when 250 flasks-of quicksilver produced, to each of the first parties.”
There is no claim but that the respondents carried out their part of the agreement by causing an assignment to be made of the one-half interest in the said lease. The transfer to Hodge, however, was made upon the express condition that the engineering and management of all the operations at the mine should be and remain in the hands of the orginal lessees, Winterburn and Napier. The lease referred to in the agreement of assignment was a five years’ lease of the mine. It required the lessees to keep two men constantly employed, and provided for the forfeiture of the lease (at the option of the company) on failure of the lessees to do so. The lessees were to pay the company as rent one tenth of the gross product of the mine; and it was further provided in the lease that whenever, in the judgment of the lessees therein named, five hundred tons of ore of a sufficient value to justify reduction should be extracted from the mine, that they should have the same reduced at the works of the New Idrian Mining Company, or immediately begin work for the construction of a furnace for that purpose. The agreement between the respondents and Hodge imposed no express obligation upon the latter to work the mine, though I think it fairly inferable therefrom that it was understood between the parties to it that he would, in connection with the said Winterburn and Napier, work it, and that the terms of the lease would be observed. Hodge agreed to make the deferred payment to the respondents when 250 flasks of quicksilver had been produced, and if he, or his representative, refused to go on with the work when there was a reasonable probability that the mine, if worked in the ordinary mode and process in which such affairs are carried on, would have produced quicksilver in such quantities as to justify its development, said pay
