Joseph McKenna, United States v. Erie Railroad Company…
“ We cannot so confine it. The statute certainly cannot mean that the described business should have no relation to the past and no connection with the future, however near. It may be that there might be a business so completely consummated or so much in speculation that it could not be described as 'current,' but the letters with which this case is concerned are not of either character. They regard not only immediate, but day-by-day action, and so relate to 'current,' as distinguished from exceptional, business. ”
