Through the years I've known a little bit of something about the Freedman's Bureau, but I think I've never known its full name:
This was an act of federal relief proposed by Abraham Lincoln in 18651 empowered to help the newly-freed slave transition to their new life. The "Abandoned Lands" part was very unsettling, in a way equating refugees and newly-freed slaves with real estate. But it was the language and practice of the time, and economy of presentation, and logic, I guess, that lead to this title. The bureau here was the Military, which was run by General O.O. Howard. The Bureau functioned from 1865 until it ran out of steam (along with other Reconstruction efforts and measures) in 1872.
In a way it reminded me somewhat of the fight for the capitalization of the "N" in the word "Negro" (see here)--something that seems beyond the scope of thinking about nowadays, but it was a battlefield for decades after the Civil War, with that "N" not being decided positively until the 1920's in common usage. "Abandoned Lands" is not the same thinking-point as "N", though it does make one think about what was in the common thinking that these three titles could be brought together as a single bureau, regardless of the hyper- and sub-text of the meaning associations via proximity
Sec. 1. "...a bureau of refugees, freedmen, and abandoned lands, to which shall be committed, as hereinafter provided, the supervision and management of all abandoned lands, and the  control of all subjects relating to refugees and freedmen from rebel states, or from any district or county within the territory embraced in the operations of the army..."
Sec. 2 "And be it further enacted, That the Secretary of War may direct such issues of provisions, clothing, and fuel, as he may deem needful for the immediate and temporary shelter and supply of destitute and suffering refugees and freedmen and their wives and children..."
