8th Grade English
Read the passage from "A Cub Pilot":

I was helpless. I did not know what in the world to do. I was quaking from head to foot, and I could have hung my hat on my eyes, they stuck out so far.

“Quarter twain! Quarter twain! Mark twain!”
We were drawing nine! My hands were in a nerveless flutter. I could not ring a bell intelligibly with them. I flew to the speaking-tube and shouted to the engineer,
“Oh, Ben, if you love me, back her! Quick, Ben! Oh, back the immortal soul out of her!”

I heard the door close gently. I looked around, and there stood Mr. Bixby, smiling a bland, sweet smile. Then the audience on the hurricane-deck sent up a thundergust of humiliating laughter. I saw it all now, and felt meaner than the meanest man in human history. I laid in the lead, set the boat in her marks, came ahead on the engines, and said,

“It was a fine trick to play on an orphan, wasn’t it? I suppose I’ll never hear the last of how I was stupid enough to heave the lead at the head of 66.”

Well, no, you won’t, maybe. In fact I hope you won’t; for I want you to learn something by that experience. Didn’t you know there was no bottom in that crossing?”
“Yes, sir, I did.”

You will write one well-developed paragraph of at least 7-8 sentences.

In your paragraph, identify one major idea in the memoir "A Cub Pilot." Then identify one sentence in the passage that directly develops or refines that main idea.
