At what period this intrusive Indo-Germanic column made its attack cannot be ascertained. The national vocabularies of Europe, to which we must resort for evidence, might lead us to infer that the condition of civilization of the conquering people was not very advanced. They were acquainted with the use of domestic animals, farming implements, carts, and yokes; they were also possessed of boats, the rudder, oars, but were unacquainted with the movement of vessels by sails. These conclusions seem to be established by the facts that words equivalent to boat, rudder, oar, are common to the languages of the offshoots of the stock, though located very widely asunder; but those for mast and sails are of special invention, and differ in adjacent nations. [Sidenote: Their civil state deduced from their vocabularies.] In nearly all the Indo-Germanic tongues, the family names, father, mother, brother, sister, daughter, are the same respectively. A similar equivalence may be observed in a great many familiar objects, house, door, town, path. It has been remarked, that while this holds good for terms of a peaceful nature, many of those connected with warfare and the chase are different in different languages. Such facts appear to prove that the Asiatic invaders followed a nomadic and pastoral life. Many of the terms connected with such an avocation are widely diffused. This is the case with ploughing, grinding, weaving, cooking, baking, sewing, spinning; with such objects as corn, flesh, meat, vestment; with wild animals common to Europe and Asia, as the bear and the wolf. So, too, of words connected with social organization, despot, rex, queen. The numerals from 1 to 100 coincide in Sanscrit, Greek, Latin, Lithuanian, Gothic; but this is not the case with 1000, a fact which has led comparative philologists to the conclusion that, though at the time of the emigration a sufficient intellectual advance had been made to invent the decimal system, perhaps from counting upon the fingers, yet that it was very far from perfection. To the inhabitants of Central Asia the sea was altogether unknown; hence the branches of the emigrating column, as they diverged north and south, gave it different names. But, though unacquainted with the sea, they were familiar with salt, as is proved by the recurrence of its name. Nor is it in the vocabularies alone that these resemblances are remarked; the same is to be said of the grammar. M. Max Müller shows that in Sanscrit, Zend, Lithuanian, Doric, Slavonic, Latin, Gothic, the forms of the auxiliary verb _to be_ are all varieties of one common type, and that "the coincidences between the language of the Veda and the dialect spoken at the present day by the Lithuanian recruits at Berlin are greater by far than between French and Italian, and that the essential forms of grammar had been fully framed and established before the first separation of the Aryan family took place."
