ALPHABETIC LAND REGISTRY
A distinguishing character was attributed to eachsquare
metre. Disposing of only 26 letters in the alphabet we reutilized
the letters in sequence as long as this was required. Each plot
was also attributed a number using invisible ink to preserve the
mystery of the operation. Cross-referencing using X and Y axes
enables one to automatically locate each territorial element,
by using original calculations, the simplicityof this not being
apparent... to those unfamiliar with differential
equations; and Lord knows just how many of us exist !
