238 THE ESSEX NATURALIST. Though widely spread then throughout Europe, its gram is rare in Bronze Age deposits ; no Iron Age examples have been found. More important still, the grain raised in prehistoric Europe is like that of the typical wild "species" : the grain raised in modern Europe is like that of the wild "variety" which is confined to Asia. The "method of elimination," supported by hints given by Theophrastus as to its habit, suggests that this is the Greek cereal known as τίφη, and it may be for scholars to consider whether this was not also the Assyrian cereal named saide or suilla, the Sumerian cereal ZAG. HI. LI, mentioned so often in the "Assyrian Herbal." It is by no means impossible that the large-grained "wild" variety of Syria, Asia Minor and Kurdistan is a "spontaneous" survival from former cultivation ; whatever the origin of the Neolithic crop may have been, the Einkorn or Locular still grown in parts of Europe may, like Woad, be one of the gifts for which Western civilization has to thank the early culture of Asia Minor. Most botanists are likely to agree that Triticum dicoccum, the most primitive cultivated "race" of wheats with 14 pairs of chromosomes, for which Prof. Percival uses the name Emmer, is as old as the Einkorn or Locular. It was as widely grown as the latter in Central Europe in Neolithic days, and continued to be of importance, at least in Switzerland, during the Bronze period. It was grown in Egypt by the predynastic Badarians, and is known to have been cultivated in dynastic Egypt from 5400 b.c. down to the date of the Greek conquest ; it was the chief cereal of Mesopotamia from at least 4000 b.c. down to the time of the Persian conquest. If the cultivation of Emmer began in Egypt, a point that is only doubtful because some scholars deduct a millenium and a half from the generally accepted dates for the first Egyptian Dynasty, it is certain that this wheat is not "wild" in Egypt. We are indebted to a Greek author for the transmis- sion of the Egyptian legend that Emmer was brought to Egypt by Isis, who had found it and barley growing wild, "on a high "mountain in Phoenicia, far away." Another Greek writer has preserved for us, by quotation, a passage from a history now lost, written by a priest of Babylon, which says that wheat grew wild in the hills between the Upper Euphrates and the Upper Tigris. In 1855 a European botanist just missed the opportunity of making the old Egyptian myth come true : among specimens of
