But the chief point of interest in regard to the excavations at El-Hibba and Surghul was the discovery of a number of early graves. Many of the bodies had been burnt, from which Koldewey inferred that cremation[22] was one of the ways in which the Sumerians of antiquity disposed of their dead. Many of the inscriptions recovered were published by the lately deceased Dr. Messerschmidt. The tablets in question include texts belonging both to first and second Dynasties of Lagash (Tellô). One of the tablets unearthed at Surghul and written by Gudea, the most famous ruler of the Second Dynasty of Lagash, showed that both El-Hibba and Surghul acknowledged Gudea as their suzerain-overlord. At about the same time, the excavating spirit in America was also gradually fanning itself into life, and to-day America is doing more archæological work than any other country in the world. The ancient city of Nippur had long been known as one of the most famous centres of Babylonian religion, and of the worship of the great god En-lil, and it was accordingly to this city that the Americans first directed their attention, and it was here that they made those epoch-making discoveries which have won for them so prominent a place in the history of Mesopotamian excavation, and that in spite of all the controversies which have arisen out of those discoveries. The Americans had indeed sent out an expedition to Babylonia as early as 1884 under the directorship of Dr. W. Hayes Ward of the New York “Independent,” but the object for which it was sent was general exploration rather than for actual excavation. The first expedition (1888-89) to Nippur, which was organized chiefly by Prof. J. P. Peters, who was supported by Dr. Wm. Pepper, Provost Harrison, Messrs. E. W. Clay, C. H. Clark, W. W. Frazier, and others, was chiefly tentative in character, and served rather to show the magnitude of the work to be accomplished than to achieve any definite and practical results. Peters was the director of the first and second (1889-90) expeditions, while Prof. R. F. Harper and Prof. H. V. Hilprecht were appointed Assyriologists to the first expedition, Mr. Field being the architect. The first expedition was engaged in excavating for two months and nine days, while the second excavated for three months and eleven days. Dr. Haynes was the field-director of the third expedition (1893-96), and remained at the mounds of Nippur for nearly three years without a break. The fourth expedition (1898-1900) was conducted by Hilprecht as scientific director, Haynes as field-director, and Messrs. C. S. Fisher and H. V. Geere as architects, and during the last campaign excavations were carried on for some sixteen months, and led to many important discoveries.
