I've filled the grid apart from:
Helps for Ed's horses if day's moved earlier (6).
I've got STED?S. Stedds and Stedes both fit and "steads" is helps in Spenser. Shouldn't it be if day's moved later so that steeds becomes stedes?
I've also got the instruction but that makes little sense at the moment. I need to think like Fred Flintstone, it seems.
