the clatter of the little white ball seeking its owner's salvation, the musically liquid swickety 'swish-'swish of the American cocktail, the tap'tap'tap of hammers where joy palaces are being shot up overnight to accommodate the business of this prohibition
1.does swish-swish mean sound of glasses?2what is the meaning of swickety3. what does the underlined clause mean?
The person seeking salvation from the little white ball isn't its owner; it's the customer. (The owner does seek to make money, but not salvation.)
The business of this prohibition is the gambling business (which isn't prohibited, just restricted - that is, prohibited in certain circumstances). The reference is presumably to Prohibition - Wikipedia, the free encyclopedia . This sort of ban can result in the rapid growth of criminal organizations developed to get round the law.
'Swickety' is probably a made-up word (in which several other onomatopoeic words are combined: swish, click, and clatter...). Swish swish isn't the sound of glasses (which 'chink' when they're banged together) - the whole thing ('swickety swish swish') is the sound of a cocktail being stirred with a 'swizzle stick'. 'Swickety' just makes 'swish swish' sound more percussive; the cocktails, presumably have ice in them.
I really don't think this is good enough writing to merit the attention of anyone - certainly not an ELT student.
