1901. A cross-cut over the ridge of mounds between Kasr and Sachn was effected, February-April; the south-west building of the Kasr was examined, April-May; and the excavations at Ishin aswad with the Ninib Temple carried out, July-December.
1902. The Ishtar Gate was excavated, February-November; the temple “Z,” January-February; overlapping work at Borsippa, February-April; and Fara, June 1902–March 1903.
1903. The north-east corner of the Southern Citadel with the vaulted building was explored, December 1902–January 1904.
1904. The mounds of Homera were worked through with the Greek theatre, January-April; and the inner city wall was begun in April. In the Southern Citadel the excavation was carried farther west, and the eastern portion of the palace of Nabopolassar was excavated, April 1904–February 1905.
1905. The inner city wall was partially opened up, January-March. The excavations, by order of the Turkish Government, were temporarily deferred, April 7–June 23; the two mud walls to the north of the Southern Citadel were commenced in June, and the Sargon wall with the beginning of the Arachtu wall was verified.
1906. The western boundary of the Southern Citadel with the two bastions on the north-west was excavated, and also the moat wall of Imgur-Bel, the Persian Building, and the south-west corner of the Southern Citadel, till June 1907.
1907. From the Persian Building a long exploration trench was carried through the western quarter, December 1906–March 1907; the eastern ends of the two mud walls in front of the Ninmach Temple were excavated, June-October, and a small piece of the outer wall near Babil, June-July. In October the southern quay wall of the canal south of the Kasr was followed up farther and the excavations in Merkes were begun, which with varying degrees of activity have been carried on up to the present time, May 1912.
1908. The main work lay in Merkes. It led inter alia to the uncovering of the earliest strata that have yet been reached and that belong to the period of the earliest Babylonian kings. In February, as a lengthy secondary piece of work, the opening up of Sachn was begun at the Tower of Babylon and lasted till June 1911. Also in July a cut was made through the quarter to the west of Sachn, which brought to light the Arachtu wall and the Nabonidus wall at this place.
1909. The main work still lay in Merkes, where the strata of the dwellings of Nebuchadnezzar’s period were laid bare in large connected areas.
1910. In January the main work was transferred to the north-east strip of the Kasr, where the northern ends of the two walls that flank the Procession Street were brought to light, that now—May 1912—are almost finished. Here also the lengths of wall that project eastwards were opened up. As an additional piece of work the following up of the Arachtu wall from the Kasr to Amran was begun with the embankment walls of Nebuchadnezzar and Nabonidus that lay in front of it, April 1910–January 1911; this led to the discovery of the stone bridge over the Euphrates, August-November. The researches in Merkes were carried on with the opening up of more private houses and the Temple of Ishtar of Agade, November 1910–October 1911. Also, as a secondary piece of work, the outer walls of the temple of Esagila were identified, December 1910–July 1911.
