Today’s Saturday Stumper

Today’s Newsday  Saturday Stumper is by the puzzle’s editor, Stan Newman, composing as Lester Ruff (“less rough”). I found it an easier Stumper, with some tough spots, but always with a way to keep going.

Some clue-and-answer pairs of note:

4-D, six letters, “Advisor to Achilles.” Well, yes, if giving advice once is enough to make someone count as an advisor. I think that this characterization better befits Patroclus.

5-D, eleven letters, “Lone Ranger’s grand-nephew.” It’s true. I didn’t read enough comic books.

6-A, four letters, “Nautical prefix.” Remember, it’s a Stumper.

6-D, eight letters, “What forest replanting supports.” Tricky.

23-A, fourteen letters, “Gershwin orchestral sequel.” I like a Gershwin tune. How about you?

30-D, nine letters, “Font of creativity.” Well, it’s not COMICSANS.

45-A, fourteen letters, “Highs and lows.” Nicely opaque.

My favorite clue in this puzzle: 11-D, nine letters, “Take it slow.”
