What two factors stayed the same when proteus was paddled across river?

When Proteus was paddled across the river, two things stayed the same. The first was the sound of the water beneath the canoe, which was constant and unchanging. The second was the feeling of the sun on Proteus's skin, which was warm and comforting. These two constants provided a sense of security and continuity for Proteus as he journeyed across the river.
