The attorneys thus employed shall work in conjunction with the district attorney for the parish in which the land is situated. The compensation of the district attorneys shall remain as now fixed by law; but the compensation of the other attorneys employed shall be fixed by contract between the respective school boards and the attorneys employed, and shall in each case be a contingent fee, conditioned upon recovery. The fee shall in each case be a fixed percentage of the amount recovered, and shall in no case exceed twenty-five per cent of the amount recovered. If more than one attorney is employed for the same cause, the same fee shall be paid to the whole number of attorneys, as if only one had been employed.
