This covered with three layers of the purest gutta percha, separately applied, in the manner usual with telegraphic wire. The core thus formed by the treble covering of gutta three-eighths of an inch in advantage thereby gained in the integrity of insulation is of the highest importance. The core of this gigantic cable (2500 miles in length) is now in the course of manufacture, under the superintendence of Mr. Samuel '. From "Illustrated London News", 1857.
