It will require but a single example, familiar to all, to still more forcibly show that it is _language_ through whose agency national traits of character and physical development are produced. How do you suppose that the wonder has been wrought, and is still daily being worked, of the great mass of humanity reaching these shores from foreign lands being merged into one homogeneous nation? The remark is often made that "it is the climate." If it were the climate, or other conditions specifically belonging to this country, how is it that foreigners coming here at maturity always remain foreigners, while their offspring born and bred here become Americans? Even children born elsewhere, but coming here at an early age, soon become "Americanized," while their parents remain foreigners always. These children must have taken a potent draught, not partaken of by their parents, to not only change their mode of vocal but also of physical expression; nay, the vital expression of their entire being. That draught is the English language. Most foreigners respectively married to an American wife or husband, and rearing a family of American children, remain foreigners to the end of their lives. It often happens that parents of foreign birth cannot comprehend the character and actions of their own children, who are _so_ different, being superficial and frivolous, where they are deep and sound; cool and calculating where they are fire and flame. Yet these children possess sterling qualities of another kind which their parents do not possess. I call to mind two brothers, sons of German parents, born in this country. With the eldest-born the German influence was potent. He was made to speak German at home and at school, and is to-day, though married to an American, more German in his manner and appearance than American, while his mode of speaking the English language also has something "German" in it. His brother, on the other hand, more particularly reared under native influences, is a thorough American. There was nothing in this case but the influence of language which could have caused this difference. Similar examples might be cited endlessly.
