For purposes of [subdivision](/usc/16/539m–1.md?p=15) (1) of [section 164 of this title](/usc/16/164.md) the value of all patented lands within said [park](/usc/16/410r–5.md?p=c-3), including the timber thereon, offered for exchange, and the value of the timber on [park](/usc/16/410r–5.md?p=c-3) lands, or on Government lands within the metes and bounds of the national forests within the [State](/usc/16/590q.md?p=a) of Montana, proposed to be given in exchange for such patented lands, shall be ascertained in such manner as the [Secretary](/usc/16/410r–5.md?p=c-1) of the Interior and the [Secretary](/usc/16/410r–5.md?p=c-1) of Agriculture may jointly in their discretion direct, and all expenses incident to ascertaining such values shall be paid by the [owners](/usc/16/429b–3.md?p=4) of said patented lands.
