"Beacons in exposed situations are constructed sometimes of stone, and cement-concrete or cement-rubble, but generally of castiron columns let into heavy base plates which are fixed to the rock by strong lewis bats. The small class iron beacons are generally of malleable iron and the larger of cast-iron butt steel or bronze might with advantage be used in very exposed places." —The Encyclopedia Britannica, 1910

"First Application of Total Reflexion to Fixed Lights. In this apparatus Fresnel substituted his totally reflecting prism p and lens R for Marcet's reflector, and thus distributed the whole light equally over the horizon by means of dioptric agents alone. This was the first application of total reflexion to lighthouse apparatus, and this beautiful instrument continues till now in universal use." —The Encyclopedia Britannica, 1910

"Fresnel's Revolving Light. —In this form of revolving light the central burner is surrounded by annular lenses L, and a compound arrangement of inclined trapezoidal lenses L' and plane silvered mirrors M. The inclined lenses fit closely to each other and form a pyramidal dome, and the light, intercepted by them, is sent upwards in inclined beams until, falling upon the plane mirrors M, it is sent outwards in horizontal parallelized beams. All these optical agents are made to revolve round the central lamp, and the sailor receives a full flash when the axis of one of the emerging beams passes his eye, and as soon as it passes him he is in darkness until the next beam comes round." —The Encyclopedia Britannica, 1910

"Holophotal Catadioptric Apparatus Revolving round a Central Flame.—If in place of Fresnel's compound arrangement of trapezoidal lenses and plane mirrors there are substituted mirrors R, R generated by the revolution of a parabolic profile round a horizontal axis, all the light will be at once sent out in parallel beams by them and the lenses L, and the apparatus is therefore geometrically perfect, but metallic instead of glass agents are still employed." —The Encyclopedia Britannica, 1910

"Tybee Island, Savannah River, Ga.- Views of the lighthouse and barracks- destruction of the lighthouse by the Confederates. Among the numerous structures erected by the United States on the long line of the stormy Atlantic coast for the benefit of the commerce of the world and the safety of the mariners of all nations, none were finer or more useful than the lighthouse on Tybee Island, at the mouth of the Savannah River, familiarly known to sailors as Tybee Light. It was a fixed light, one hundred and eight feet high, and could be seen at a distance of twelve miles. In common with all the other lights on the Confederate coast, it was extinguished by the Georgians soon after the secession of their State. The day after the Federal fleet made its appearance off the mouth of the Savannah River, the Confederates set fire to the interior of the lighthouse, which was burnt, and the costly reflectors destroyed. A similar vandalic measure was resorted to by the Confederates of Charleston, when the Stone Fleet appeared off that harbor. They blew up the celebrated 'Charleston Light.'"— Frank Leslie, 1896

"Eddystone is a group of gneiss rocks, daily submerged by the tide, in the English Channel, 9 miles off the Cornish coast, and 14 S.S.W. of Plymouth Breakwater. The frequent shipwrecks on these rocks led to the erection of a lighthouse on them in 1669-1700, but the great storm of Nov. 20, 1703 completely washed it away. Another lighthouse was built in 1706-1709. This was burned in 1755. The next, noted for its strength and the engineering skill displayed in it, was constructed in 1757-1759. The granite was dovetailed into the solid rock, and each block into its neighbors. As the rock in which this tower was built became undermined and greatly weakened by the action of the waves, the foundation of another was laid on a different part of the reef in 1879. Its light is visible in clear weather at a distance of 17 and one half miles."—(Charles Leonard-Stuart, 1911)

"Plane mirrors M revolve on an endless chain placed outside of the apparatus and alter the direction of the flashes after they pass into the dark arc on the landward side so as to cause the lenses L, L to repeat their flashes over the seaward are which requires strengthening. The condensing spherical mirror and mirror of unequal areas will also be found applicable in cases where the flashes do not require to sweep over the whole horizon." —The Encyclopedia Britannica, 1910

"In order to produce, on the catoptric system, a fixed light showing all round the circle, a number of reflectors are fixed round the outside of a stationary chandelier n. As the ordinary paraboloid has about 14 degrees of divergence, twenty-five reflectors were needed to light up continuously (though not equally) the whole horizon." —The Encyclopedia Britannica, 1910

"If again the light was to revolve, then a revolving chandelier was employed having a certain number of flat faces, on each of which was fixed a number separate lamps and reflectors with their axes parallel to each other. When the chandelier revolved, and one of the flat sides was turned towards the sailor, he would, when at some distance from the shore, receive a flash at once form each of the mirrors which were on that face, but when the face was turned away from him a dark period would intervene until the next face came round again." —The Encyclopedia Britannica, 1910

"In 1835 Mr. Stevenson, in a report to the Northern Lighthouse Board, proposed to add fixed reflecting prisms p below the lenses of Fresnel's revolving light, and he communicated this proposal to M. L. Fresnel, who approved of his suggestion, and assisted in carrying out the design in 1843. This combination added, however, but little to the power of the flash, and produced both a periodically flashing and constantly fixed light; but it must be remembered that the prism for fixed lights was the only kind of reflecting prism then known." —The Encyclopedia Britannica, 1910
