Well, I've got reasonable answers for all of them. Five of my answers are HIGHLY questionable, though. Is anyone else having problems with

 1) London's cathedral
 4) Good place for standing on a soap box
11) A reasonable trim for hedgerows or trees
13) Is this a dressmaker's assistant, or someone who puts up displays?
25) Main terminus for trains to Manchester and Glasgow

I can't decide if that last one is truly a puzzle or if it's a "real question". If they really want to know the train terminal to Manchester and Glasgow, I won't have a daydream of a chance at figuring it out.

But I actually have answers for all of them. *shrug*
