"I shouldn't wonder but what there'd be a storm," spoke Andy again, after a pause. He couldn't keep quiet for very long at a time.
"Um," was all the reply Frank made.
"What's the matter; lost your tongue overboard?" questioned Andy with a chuckle.
Frank did not reply.
"I'm going to pass you," called the younger brother a moment later when, by extreme exertion, he had regained the place he had held, with the bow of his craft in line with Frank's. Then Andy fairly outdid himself, for, though Frank was rowing hard, his brother suddenly shot ahead.
"It's about time you did some rowing," was Frank's quiet remark, and then he showed that he still had some power in reserve, for he caught up to his brother, and held his place there with seeming ease, though Andy did not let up in the furious pace he had set.
"Oh, what's the use of killing yourself?" at length the younger lad fairly panted. "It's—it's farther than I thought."
He began losing distance, but Frank, too, had no liking for the fast clip, so he, likewise, rowed slower until the two boats were on even terms, bobbing over the long ground swell that seemed to be getting heavier rapidly.
From time to time one brother or the other glanced over his shoulder, not so much to set his course, for they could do that over the stern, having previously taken their range, but in order to note the aspect of the fast-gathering clouds which were behind them.
The wind, which had died out shortly after they had started on their row that morning, now sprang up in fitful gusts, with a rather uncanny, moaning sound, as if it was testing its strength before venturing to develop into a howling storm.
