1 Down - Its contents are carried by caddies or put into bags (3,5)
?e? C????
13 Down - Sid's upset about being told to go and refuses to agree (8)
D?s?e?t?
2 Down - Silver part of a clarinet - that's not in dispute (6) ?g?e??
I'd agree ubasses if the clue was "They are carried..." but the clue is "its contents..." and tea leaves don't have contents. I wondered at first if it was TEE something (as in golf) but I can't make it work.
Is a TEA CHEST also something carried by caddies- maybe a golf term?
