2nd verse of The Dreary Black Hills
The round house in Cheyenne is filled every night
With loafers and bummers of most every plight
On their backs is no clothes, in their pockets no bills
Each day they keep starting for the Dreary Black Hills.

7th verse of Buffalo Skinners
Oh, it's now we've crossed Pease River and homeward we are bound.
No more in that hell-fired country shall ever we be found.
Go home to our wives and sweethearts, tell others not to go,
For God's forsaken the buffalo range and the damned old buffalo.

That one may be technically about those who are home-sick, not home-less, but I don't think homeless always means unemployed. alice, in mt
