THE TELEPHONE For direct communication over short or moderately long distances, nothing has been invented as yet that will take the place of the telephone.
A few years ago, when this instrument was first brought out, it was the wonder of the times, just as wireless telegraphy is to-day.
Starting with the simple form of the two cups with membranes across the ends, and a string or a wire connecting them, we have to-day the complex and wonderful electric telephone, giving perfect service up to a distance of two thousand miles.
Some day inventors in the science of telephony will make it possible to communicate across or under the oceans, and when the boys of to-day grow to manhood they should be able to transact business by ’phone from San Francisco to the Far East, or from the cities near the Atlantic coast to London, Paris, or Berlin.
It is hardly necessary to enter into the history of telephones, as this information may be readily found in any modern encyclopædia or reference work.

Chapter 9 of Harper's Electricity Book for Boys by Joseph H. (Joseph Henry) Adams holds 271 sentences, grouped into 55 reading sections of at most 5 sentences.

What does chapter 9 of Harper's Electricity Book for Boys contain?

Chapter 9 holds 271 sentences of Harper's Electricity Book for Boys, unabridged, divided into 55 reading sections.

This page carries chapter 9 of Harper's Electricity Book for Boys by Joseph H. (Joseph Henry) Adams exactly as it stands in the source edition, without abridgement. It runs to 271 sentences, grouped into 55 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 9 of Harper's Electricity Book for Boys?

Work through the 55 sections in order, replaying any sentence and tapping unfamiliar words for their entries.

Each of the 55 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 9 be read aloud to me?

Yes — every sentence and every individual word in chapter 9 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.
