45 deg.

40', about four miles from the nearest bend of the Euphrates, on its left or east bank.

They form an irregular circle, nearly six miles in circumference, which is defined by the traces of an earthen rampart, in some places forty feet high.

A vast mass of undulating mounds, intersected by innumerable channels and ravines, extends almost entirely across the circular space, in a direction, which is nearly north and south, abutting at either end upon the rampart.

East and west of this mass is a comparatively open space, where the mounds are scattered and infrequent; while outside the rampart are not only a number of detached hillocks marking the site of ancient buildings, but in one direction--towards the east--the city may be traced continuously by means of ruined edifices, mounds, and pottery, fully three miles beyond the rampart into the desert.
