Joseph, as if absently. »I shouldn't wonder if it could be made worth some one's
while to give a bit of help that way. Don't you think so?«
    In the tone of one turning to a different subject, Scawthorne asked
suddenly:
    »What use are you going to make of your father's offer?«
    »Well, I'm not quite sure Shouldn't wonder if I go in for filters.«
