[Original 1931 text] "Houses XXV and XXVI are built on the foundations of a large structure of the Intermediate I Period, of which onoy the back or west wall has been exposed. House XXV faces towards the south and like No.
Local villagers cross the site in a donkey cart in the early morning mist, with the Buddhist stupa perched on top of the "citadel" mound. The modern road winds through the low-lying area between the "citadel" and "lower town."

"At the floor level of the Late II Phase this building measured 51 feet 3 inches, North-South, by 56 ft. long at the north and about 54 feet 9 ins. at the south.
