Just these two left.
25c Tilling machine which leaves spaces spaces between the furrows(3-6) ?i? P?o?g?,assume something plough.
30ac Coastal lagoon separated from the sea by a spit of land.(4) If other answers correct H?a?

[cupid04]

30a] haff?

[Calibax]

Ard plough?

[grumpy01]

Thanks both. Don't think Haff is right because i am sure 31dn is algarroba,making my a correct.If ard plough then was does that make 7dn for which i have A Posteriori.

[Mamyalynne]

What are the clues for those other two.

[grumpy01]

7dn Empirically(1,10)
31dn The carob or mesquite(9)

[Mamyalynne]

Haff looks right..

[cupid04]

haff= a long shallow lagoon separated from the open sea by a narrow sand bar or barrier beach. [Merriam Webster dictionary]

[grumpy01]

Mamyalynne,if you agree with algarroba then the a is not in the right place.

[Mamyalynne]

So are we saying if Haff is correct then it starts 'F'?

[grumpy01]

Yes

[Mamyalynne]

hmmmmm

[Mamyalynne]

A real puzzler then, will keep thinking.

[grumpy01]

From the definition Haff certainly does look right.

[slaney]

25 Rib-plough - eventually found it in Chambers
For the other one, I wonder if the setter has confused Haff with Haaf (a deep sea fishing ground)?

[JoolsTwo]

I was thinking that slaney - I fairly sure that 31d is algarroba.

[grumpy01]

Thanks everyone for your efforts and answers.

[JRB]

I too have spent ages puzzling this one. The only light I have found is in the Dictionary of Ichthyology (???) where "haff" and "haaf" seem to be used as alternative spellings of each other.

[stevenj]

I have just discovered that "haaf" is old Norse for "sea" or "channel". Seems like it could be adapted to mean the definition in 30ac doesn't it? Or am i pushing that logic too far? Anyway back to revision...
