Answer

Here, “to work up a stake” just means to save money. “Blow their stake” means to spend all their savings quickly and recklessly. “Pound their tail” means to work hard (in this context; it could have a sexual meaning in another context).

Answer

This is old-style American slang.  It means they work on a ranch to earn money, then spend all their money in town. Because they have no money left they go to another ranch and repeat the same thing all over again.
