Continuance of land offices when required by public convenience

The Secretary of the Interior may continue any land district in which is situated the seat of government of any one of the States, and may continue the land office in such district, notwithstanding the quantity of land unsold in such district may not amount to one hundred thousand acres, when, in his opinion, such continuance is required by public convenience, or in order to close the land system in such State.
