Oklahoma v. Texas (267 U.S. 7)…
“ The special master shall receive an allowance covering his actual expenses and a reasonable compensation for his service. This allowance, together with the cost of his stenographic and clerical assistance and the cost of printing his report, shall be charged against and be borne by the several claimants in such proportions and in such manner as the court hereafter may direct. Each claimant, however, shall make to the clerk an advance payment of $50 towards such costs within 20 days from this date, and in default thereof the claimant shall be deemed to have abandoned his claim. ”
