Thank you Chris
.... we are all so much richer for your comment.
I assume that you are testing us by not having a period after "etc", since you appear to be using abbreviation of the Latin words "et cetera".
This would translate your sentence to read along the lines of: "Logs, eyes, motes and other things and other things"
I am, however, at a loss to understand why you are missing a comma after motes and the first "etc". I will however refrain from sarcasm and pointing our you obvious lack of command of basic grammar.
I would like to point out that there are three general cases where there can be confusion in when to use an apostrophe: wankers indicating a number of wankers has no apostrophe, wanker's as in ownership of an item by a single wanker has the apostrophe placed before the "s" and wankers' indicating a group of wankers places the apostrophe after the "s"..
"Under what circumstances should the apostrophe s be used?" Could possibly be written to "Under what circumstances should the apostrophe be used in conjunction with s?" but that is probably a matter of taste.
Good reference to logs and eyes - very Freudian.
