[Ger-Poland-Volhynia] "skasky"

[Richard Benert]

I've just been reading a few pages in Michail Kostiuk's new book, "Die 
Deutschen Kolonien in Wolhynien".  He talks at one point about financial 
inducements and privileges given by the government to newcoming German 
immigrants, and he calls these privileges "skasky".  He cites a 1994 source 
for this, but it's in Ukrainian, and he says nothing about what these 
"skasky" were.
He's a bit vague about the time frame.  I'm not sure if he's talking about 
the 1830s or the 1860s, or both.

Do any of our knowledgeable experts know anything about this?
