And when we cross the Atlantic we find[2] that the Arabs are divided up in the same way into tribes bearing animal names. "_Asad_, lion; 'a number of tribes.' _Aws_, wolf; 'a tribe of the Ancar, or Defenders.' _Badau_, ibex; 'a tribe of the Kalb and others.' _Tha'laba_, she-fox; 'a name of tribes.' _Garad_, locusts; 'a sub-tribe of the Azol.' _Thawr_, bull; 'a sub-tribe of Hamdan and of Abel Manah.' _Gahah_, colt of an ass; 'a sub-tribe of the Arabs.' _Hida'_, kite; 'a sub-tribe of Murad.' "The origin of all names is referred, in the genealogical system of the Arabs, to an ancestor who bore the tribal or gentile name. Thus the _Kalb_ or dog-tribe consists of the Beni-Kalb--sons of Kalb (the dog), who is in turn son of Wabra (the female rock-badger), son of Tha'laba [1. Tylor's "Early History of Mankind." 2. W. J. F. Maclennan, "Fortnightly Review," 1869 and 1870.] {p. 364} (the she-fox), great-grandson of Quoda'a, grandson of Saba', the Sheba of Scripture. A single member of the tribe is Kalbi--a Kalbite--_Caninus_." "The same names which appear as _totem_ tribes reach through Edom, Midian, and Moab, into the land of Canaan."[1] Among the Jews there was the stock of the serpent, Nashon, to which David belonged; and there is no doubt that they were once divided into totemic families. And in all this we see another proof of the race-identity of the peoples on the opposite sides of the Atlantic. Permit me to close this chapter with a suggestion: Is there not energy enough among the archæologists of the United States to make a thorough examination of some part of the deep clay deposits of Central Illinois or of those wonderful remains referred to by Mr. Curtis? If one came and proved that at a given point he had found indications of a coal-bed or a gold-mine, he would have no difficulty in obtaining means enough to dig a shaft and excavate acres. Can not the greed for information do one tenth as much as the greed for profit? Who can tell what extraordinary revelations wait below the vast mass of American glacial clay? For it must be remembered that the articles already found have been discovered in the narrow holes bored or dug for wells. How small is the area laid bare by such punctures in the earth compared with the whole area of the country in which they are sunk! How remarkable that _anything_ should have been found under such circumstances! How probable, therefore, that the remains of man are numerous at a certain depth! Where a coin is found we might reasonably expect to [1. W. J. F. Maclennan, "Fortnightly Review," 1869 and 1870.] {p. 365} find other works of copper, and all those things which would accompany the civilization of a people working in the metals and using a currency,--such as cities, houses, temples, etc. Of course, such things might exist, and yet many shafts might be sunk without coming upon any of them. But is not the attempt worth making? {p. 366} CHAPTER II.
