Chapter 14 of The Radio Boys Under the Sea by J. W. Duffield holds 58 sentences, grouped into 12 reading sections of at most 5 sentences. The text is the source edition, unabridged, and the chapter records which sentences cover which part of the work so that nothing is dropped. Every word can be tapped for its pronunciation and dictionary entry.

What does chapter 14 of The Radio Boys Under the Sea contain?

Chapter 14 holds 58 sentences of The Radio Boys Under the Sea, unabridged, divided into 12 reading sections.

This page carries chapter 14 of The Radio Boys Under the Sea by J. W. Duffield exactly as it stands in the source edition, without abridgement. It runs to 58 sentences, grouped into 12 sections of at most 5 sentences so that a reader can take the chapter in steady, finishable pieces. The chapter also stores a coverage record mapping every one of its sentences to a part of the work, which is how the edition demonstrates that no line was dropped.

How do I study chapter 14 of The Radio Boys Under the Sea?

Work through the 12 sections in order, replaying any sentence and tapping unfamiliar words for their entries.

Each of the 12 sections in this chapter is short enough to read once, hear once, and then re-read with the vocabulary in view. Tapping a word plays it alone and opens its dictionary entry with IPA, part of speech and meaning, so the reader is never forced to guess a pronunciation from spelling. Working section by section keeps a long chapter from becoming an undifferentiated wall of text, which is the usual reason a reader abandons a work of this period.

Can chapter 14 be read aloud to me?

Yes — every sentence and every individual word in chapter 14 can be played aloud in United States English.

Audio covers the whole chapter: any sentence can be played, and any single word within it can be played on its own. The voice uses United States English. For a work of this period that matters, because spelling is an unreliable guide to pronunciation for vocabulary that has fallen out of daily use, and a learner who guesses wrong tends to keep the error. Hearing the word in its own sentence, and then alone, settles it.
