With regard to Mrs. Brown-Potter, as acting is no longer considered absolutely essential for success on the English stage, there is really no reason why the pretty bright-eyed lady who charmed us all last June by her merry laugh and her nonchalant ways, should not--to borrow an expression from her native language--make a big boom and paint the town red. We sincerely hope she will; for, on the whole, the American invasion has done English society a great deal of good. American women are bright, clever, and wonderfully cosmopolitan. Their patriotic feelings are limited to an admiration for Niagara and a regret for the Elevated Railway; and, unlike the men, they never bore us with Bunkers Hill. They take their dresses from Paris and their manners from Piccadilly, and wear both charmingly. They have a quaint pertness, a delightful conceit, a native self-assertion. They insist on being paid compliments and have almost succeeded in making Englishmen eloquent. For our aristocracy they have an ardent admiration; they adore titles and are a permanent blow to Republican principles. In the art of amusing men they are adepts, both by nature and education, and can actually tell a story without forgetting the point--an accomplishment that is extremely rare among the women of other countries. It is true that they lack repose and that their voices are somewhat harsh and strident when they land first at Liverpool; but after a time one gets to love these pretty whirlwinds in petticoats that sweep so recklessly through society and are so agitating to all duchesses who have daughters. There is something fascinating in their funny, exaggerated gestures and their petulant way of tossing the head. Their eyes have no magic nor mystery in them, but they challenge us for combat; and when we engage we are always worsted. Their lips seem made for laughter and yet they never grimace. As for their voices, they soon get them into tune. Some of them have been known to acquire a fashionable drawl in two seasons; and after they have been presented to Royalty they all roll their R's as vigorously as a young equerry or an old lady-in-waiting. Still, they never really lose their accent; it keeps peeping out here and there, and when they chatter together they are like a bevy of peacocks. Nothing is more amusing than to watch two American girls greeting each other in a drawing-room or in the Row. They are like children with their shrill staccato cries of wonder, their odd little exclamations. Their conversation sounds like a series of exploding crackers; they are exquisitely incoherent and use a sort of primitive, emotional language. After five minutes they are left beautifully breathless and look at each other half in amusement and half in affection. If a stolid young Englishman is fortunate enough to be introduced to them he is amazed at their extraordinary vivacity, their electric quickness of repartee, their inexhaustible store of curious catchwords.
