What does chapter 21 of Tom Swift Among the Diamond Makers contain?

Chapter 21 holds 95 sentences of Tom Swift Among the Diamond Makers, unabridged, divided into 19 reading sections.

This page carries chapter 21 of Tom Swift Among the Diamond Makers by Victor Appleton exactly as it stands in the public-domain source edition, without abridgement. It runs to 95 sentences, grouped into 19 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 21 of Tom Swift Among the Diamond Makers?

Work through the 19 sections in order, replaying any sentence and tapping unfamiliar words for their entries.

Each of the 19 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 21 be read aloud to me?

Yes — every sentence and every individual word in chapter 21 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.
