=The Aryans= have left no account of themselves sculptured on rocks or the walls of crumbling temples; but by careful study of the languages of Aryan origin we obtain, after the lapse of four thousand years, a glimpse of the social condition of those who spoke the mother-tongue among the mountains of Bactria. We infer that nouns similar in the various derived languages,—as father (_protector_), brother (_helper_), house, door, walls, boat, grain, etc.,—are the names of objects or notions familiar to the original family.[1] Thus utilizing language as a key to what would otherwise be locked up in the unknown past, we learn that the inhabitants of the fertile Bactrian valleys were devoted to agricultural pursuits. Tilling the ground was an honorable employment, the very name _Aryan_ signifying _high-born_, _noble_. We have pictured to us law-abiding communities, grouped together in towns, ruled by chiefs and a king, recognizing family ties, entertaining exalted conceptions of woman, and a solemn regard for the marriage bond—the latter always a mark of high civilization. Language also tells us that this interesting people preferred the arts of peace to war. With the dog for his companion, the shepherd folded his flocks of sheep; with the horse and ox for his servants, the landholder broke the soil with a plough of bronze. Pigs and fowls were raised; cattle formed the chief wealth; and the cows were milked by the _daughter_ of the household—this name meaning _milk-maid_. The Aryan drove from village to village in his wheeled carriage, over well-constructed roads; worked the metals; plied the loom; moulded clay into pottery; and even navigated the neighboring waters in boats propelled by oars. He gave names to numbers as far as one hundred, was familiar with the principles of decimals, and took the moon for his guide in dividing the year into months. A Supreme Being was worshipped in Bactria, the Great Unseen, the Creator and Governor of the world. In the reference to him of controversies that were difficult to settle, we trace the origin of the later trial by ordeal. Even some of our commonest stories are derived from fables current at least two thousand years B.C. in ancient Arya. =Aryan Migrations.=—Few in number at first, the Aryans long lived peaceably together. But as the population grew denser, great bodies, either compelled to search for food in other lands or moved by a thirst for exploration, broke away at different periods from the cradle of their race, in quest of new abodes.
