The undis- turbed portions of the original deposits consisted of com- pacted clay compara- tively free of concre- tions until a depth of 20 feet or more was reached, Avhere they occur in numbers. To this level and below to the depth of 25 feet or more the an- cient workmen had penetrated and had carried tunnels horizontally in irregular fashion, doubtless at great risk from caving in of the imperfectly solidified materials above. The form of the ancient excavations and the nature of their filling are indi- cated in figure G7. The magnitude of the ancient work is almost be- yond belief, and we are led to again marvel at the enterprise and perseverance of the quarrymen, who must have been impelled to their task by interests of ^ital im- portance to the people of the valley. ^ . ]\ >"^?^ M The implements emplo^'ed in the quarry work in- Quarry Imple- it ^ iii ments cludc rude blades resembling the oi'- dinary flint hoe of the region, which show traces of wear by use in digging, and a number of blunt, somewhat paddle or club like tools made from oblong chert concretions by rough chipping a haft at the narrow end and a scraperlike bevel at the broad end (fig. 68). The latter tool appears to have been used in freeing the concretions from the compact matrix by prying and tapping processes, and in.
