 The railway tracks were probably also used by a company that harvested a rich anthrosol, locally called sibakh, which consists of decomposed organic debris, left by the ancient Egyptians.The workers, who dug pits for removing the soil, found well preserved papyri, which were sold to collectors and museums.This caused some interest by archeologists, who closed a deal with the Italian managers of the company that sold the compost, by which the team of the archeologists had to dig-out a sufficient amount of compost to keep the company and their rail vehicles busy, while they were searching for the papyri from 1928 to 1935.
