Any pointers on my last two, please?
4d Gauge measurement for English city (7)
?E?G?N?
(not confident about the G)
17d Hole in small chamber where bread absorbs much water (3,4)
?O? S?A?
I'm a bit cross about this crossword (not enough clues; too many solvable from letter pattern alone), so I don't intend knocking my brains out on it.
