"You think so now," answered Mr. Weatherby, "but wait until you have to handle a boat in a storm. Then the waves bang the rudder about so that the wheel whirls around, and almost lifts you off your feet. More than once it's gotten away from me, though, when there's a bad storm, I have some one to help me put her over and hold her steady. I like steam steering gear best, for it's so easy, but it's likely to get out of order at a critical moment, and, before you can rig up the hand gear, the boat has gone on the rocks."
"I hope we don't get wrecked on the rocks," said Nat, as, following the directions he had received, he shifted the wheel slightly to keep the vessel on her proper course.
"Well, we'll be approaching a dangerous passage in a few hours," replied the pilot. "There are a number of rocks in it, but I think I'll be able to get clear of 'em. I always have, but this time we'll arrive there after dark, and I like daylight best when I have to go through there."
"Do you want to take the wheel now?" asked the boy, as he saw that Mr. Weatherby was peering anxiously ahead.
"No, you may keep it a while longer. I just wanted to get sight of a spar buoy about here. There it is. When you come up this route you want to get the red and black buoy in line with that point, and then go to starboard two points, so."
As he spoke Mr. Weatherby helped Nat put the wheel over. The big freighter began slowly to turn, and soon was moving around a point of land that jutted far out into the lake.
Nat remained in the pilot-house more than an hour, and, in that time, he learned many valuable points. At the suggestion of his friend he jotted them down in a note-book, so he might go over them again at his leisure, and fix them firmly in his mind.
As the afternoon wore on, and dusk approached, a fog began to settle over the lake. Nat, who had been engaged with the work in the purser's office, had occasion to take a message to the pilot, and he found his friend anxiously looking out of the big windows in front of the pilot-house, while Andrew Simmon, the assistant, was handling the big wheel.
"I don't like it, Andy; I don't like it a bit," Mr. Weatherby was saying. "It's going to be a nasty, thick night, and just as we're beginning that risky passage. I've almost a notion to ask the captain to lay-to until morning. There's good holding ground here."
"Oh, I guess we can make it," replied Andrew confidently. "We've done it before, in a fog."
