"Yes, they're with him. Your ship broke in half in the storm.
The Doctor had tied you down when he found you stunned. And the part you were on got separated and floated away. Golly, it was a storm! One has to be a gull or an albatross to stand that sort of weather. I had been watching for the Doctor for three weeks, from a cliff-top; but last night I had to take refuge in a cave to keep my tail-feathers from blowing out. As soon as I found the Doctor, he sent me off with some porpoises to look for you. A Stormy Petrel volunteered to help us in our search. There had been quite a gathering of sea-birds waiting to greet the Doctor; but the rough weather sort of broke up the arrangements that had been made to welcome him properly. It was the petrel that first gave us the tip where you were."
"Well, but how can I get to the Doctor, Miranda?--I haven't any oars."
"Get to him!--Why, you're going to him now. Look behind you."
I turned around. The moon was just rising on the sea's edge. And I now saw that my raft was moving through the water, but so gently that I had not noticed it before.
"What's moving us?" I asked.
"The porpoises," said Miranda.
I went to the back of the raft and looked down into the water.
And just below the surface I could see the dim forms of four big porpoises, their sleek skins glinting in the moonlight, pushing at the raft with their noses.
