CUSINS. Let me advise you to study Greek, Mr Undershaft. Greek scholars are privileged men. Few of them know Greek; and none of them know anything else; but their position is unchallengeable. Other languages are the qualifications of waiters and commercial travellers: Greek is to a man of position what the hallmark is to silver. BARBARA. Dolly: don't be insincere. Cholly: fetch your concertina and play something for us. LOMAX [doubtfully to Undershaft] Perhaps that sort of thing isn't in your line, eh? UNDERSHAFT. I am particularly fond of music. LOMAX [delighted] Are you? Then I'll get it. [He goes upstairs for the instrument]. UNDERSHAFT. Do you play, Barbara? BARBARA. Only the tambourine. But Cholly's teaching me the concertina. UNDERSHAFT. Is Cholly also a member of the Salvation Army? BARBARA. No: he says it's bad form to be a dissenter. But I don't despair of Cholly. I made him come yesterday to a meeting at the dock gates, and take the collection in his hat. LADY BRITOMART. It is not my doing, Andrew. Barbara is old enough to take her own way. She has no father to advise her. BARBARA. Oh yes she has. There are no orphans in the Salvation Army. UNDERSHAFT. Your father there has a great many children and plenty of experience, eh? BARBARA [looking at him with quick interest and nodding] Just so. How did you come to understand that? [Lomax is heard at the door trying the concertina]. LADY BRITOMART. Come in, Charles. Play us something at once. LOMAX. Righto! [He sits down in his former place, and preludes]. UNDERSHAFT. One moment, Mr Lomax. I am rather interested in the Salvation Army. Its motto might be my own: Blood and Fire. LOMAX [shocked] But not your sort of blood and fire, you know. UNDERSHAFT. My sort of blood cleanses: my sort of fire purifies. BARBARA. So do ours. Come down to-morrow to my shelter--the West Ham shelter--and see what we're doing. We're going to march to a great meeting in the Assembly Hall at Mile End. Come and see the shelter and then march with us: it will do you a lot of good. Can you play anything? UNDERSHAFT. In my youth I earned pennies, and even shillings occasionally, in the streets and in public house parlors by my natural talent for stepdancing. Later on, I became a member of the Undershaft orchestral society, and performed passably on the tenor trombone. LOMAX [scandalized] Oh I say! BARBARA. Many a sinner has played himself into heaven on the trombone, thanks to the Army. LOMAX [to Barbara, still rather shocked] Yes; but what about the cannon business, don't you know? [To Undershaft] Getting into heaven is not exactly in your line, is it? LADY BRITOMART. Charles!!!
