To obtain the next permit after completing Clemens Cave in Rune Factory: A Fantasy Harvest Moon, follow these detailed steps:

1. Complete the Tilling Requirement:
– Ensure you have tilled at least 50 squares of field inside Carmite Cave. You do not need to plant any seeds; simply using your hoe on the fields is sufficient.

2. Visit Mayor Godwin:
– After completing the tilling requirement, head back to Kardia and visit Mayor Godwin at his home, which is downstairs.

3. Obtain the Permit:
– Talk to Mayor Godwin. He will provide you with the permit once he is informed that you have completed the tilling requirement.

4. Explore the Next Cave:
– With the permit in hand, you can now explore the next cave, which in this case is Toros Cave.

5. Additional Tasks (Optional):
– Before proceeding to Toros Cave, you might want to visit the Library to see Russell, which is part of the village exploration task requested by Godwin before issuing the permit for the next cave.

By following these steps, you will be able to obtain the permit needed to access Toros Cave and continue your adventure in Rune Factory: A Fantasy Harvest Moon.
