It happens that your lighthouse will be on an island in the identical Mediterranean Sea in which the Colossus was reared, only not on the same side of the water. The island of Pharos has a neck of land, built by men, which stretches through the water to the city of Alexandria, making it easy to go back and forth for building material. You must have plenty of ground space for your new style of beacon-light, because the foundation is to be very large, about six hundred feet square, and the building will be many stories, growing smaller and smaller in size as the stories extend upward. The lighthouse must be five hundred feet high, that the light may be seen miles out at sea.

Building the Pharos of Alexandria

Stiff, white paper will answer for the stone.

Cut the Foundation

piece like [Fig. 315] with a square centre measuring five inches along the dotted lines on each of the four edges. Near two of the edges are long slits (A A). Extending out from the centre square are the four sides of the square, each an inch and a half in depth. On one end of each side there is a flap, C, at the opposite end a slit, B, and two of the sides have an extra extension, or bottom flap, D. Cut all of the heavy lines and carefully crease the dotted lines. The best way to make [Fig. 315] is to cut a piece of paper eight inches wide and eleven inches long ([Fig. 316]). Run a line lengthwise across one inch and a half from the outer edge ([Fig. 317]); repeat the same on the opposite edge ([Fig. 318]); then mark a line across each of the ends three inches from the edge ([Fig. 319]). Make another line midway between this line and the edge at each end, which will bring the division one inch and a half from the edge E, E ([Fig. 320]). Crease all the lines, bending them inward. Open out the paper after each folding, and when all lines have been creased and opened you will find it very easy to mark and cut the sides and flaps of [Fig. 315].
