The Transverse Plates.

These plates have the passage cut through them—they form roof, sides, and floor—they symbolise the "Zone of water." they surround the passage as this "Zone of water" surrounds the earth, and the position of each is in the terms of the Problem, in the terms of the inch, etc., which will be too long to treat of here.

Then, when we have arrived at the south end of this passage, we have arrived, symbolically, at the commencement of the Period of Repose, when the "Zone of water" will remain at rest during all these 7743 years. I will ask you to refer to the figure. You see the arc EB equals 1369.5 years, equals half of AB, and when the perihelion is distant more than 23½° from the equinox, the obliquity of the ecliptic has reached its maximum of inclination ±, and during the 7743 years the perihelion is travelling from B round past the solstice S, to the point C, or within 23½° of the opposite equinox, the "Zone of water" remains stationary.

This is symbolised by the Ramps, because the Ramps symbolise the Periods of Repose which occur in each hemisphere, and the space between them symbolises the arc AB = 2,739 years the space is equal to 42 inches, then, 42 × (1304 ÷ 10 ÷ 2) = 2739; this, ÷ 2 = 1369.5 = the arc EA × 2 = the arc AB, etc.
