The Arabs of Midian always compare the Hutaym with the Ghagar (Ghajar) or Gypsies of Egypt; and this is the point which gives the outcasts a passing interest. I have not yet had an opportunity of carefully studying the race; nor can I say whether it shows any traces of skill in metal-working. Meanwhile, we must inquire whether these Helots, now so dispersed, are not old immigrants of Indian descent, who have lost their Aryan language, like the Egyptian Ghajar. In that case they would represent the descendants of the wandering tribes who worked the most ancient ateliers. Perhaps they may prove to be congeners of the men of the Bronze Age, and of the earliest waves of Gypsy-immigration into Europe.
