Note 67 — MINOR ANTIQUITIES
Reading edition
At several places on the surfaces of projecting rocks forming the foundations of buildings may be noticed grooves where metates were sharpened. One or more of these occur at the entrance to the "street" in front of room 51. The foundation of a wall in one room was built directly upon one of these grooves, part of the groove being in sight, the rest covered with masonry. Near room 92 there are many of these grooves as well as small pits.
