25 U.S.C. § 148 — Appropriations for supplies; transfer to Indian Service supply fund; expenditure

This section is a single, undivided rule. It lets the Secretary of the Interior combine money that comes from different appropriations and funds set aside to buy supplies for the Indian Service. The Secretary can transfer whatever amount is estimated to be needed. That money moves into one place: a fund the Treasury tracks as the "Indian Service supply fund." The Secretary is authorized to spend from this combined fund to pay for supplies purchased through Indian warehouses for the Indian field service. Afterward, the government makes necessary adjustments. Each original appropriation or fund is ultimately charged only for the cost of the supplies it was legally supposed to pay for. So combining the money into one fund is just a bookkeeping convenience — it doesn't change which appropriation is truly responsible for which supply costs.
