[25]Just as the word telegraph means to "write afar off," so the word telephone means to "sound afar off."
Transcriber's Notes:
Hyphenation, punctuation, and spelling standardized when a predominant choice was available; otherwise unchanged.
Illustrations have been repositioned closer to the text that refers to them, and in many cases, their relative sizes have been changed. On some display devices, clicking a blue-bordered illustration will show a larger, higher-resolution version in the current window.
On some display devices, page numbers of the original book are shown as [123] in the right margin. The ones for some full-page illustrations have been omitted.
Page [81]: illustration captioned "[FIG. 11.—DANIEL WEBSTER'S PLOW.]" is referenced in footnote [12].
Page [147]: text apparently omitted after "of one piece"
Page [198]: reference to "Fig. 1" is incorrect.
Index entry for "[Iron, history of, 41-63.]" probably should be "41-53."
