Help greatly appreciated parsing these.....
30d. Powder dropping from the horse? (7) - SAWDUST (Powder?)
31d. Does it show any alacrity? Some (5) - NYALA (Hidden ...aNY ALAcrity)
Where is the definition?
45d. Satellite: is it not rising over far side of the sea? (7) - TITANIA (Satellite)
I can see AINT for 'Is it not', but what's the rest?
