Under this arrangement, the quotation, a received from the Exchange in New York, were wired in Morse code to Boston, where they were

decoded and wired to the tickers, the wire of other companies being in part used in the process. Held, that the transmission of the quotations remained interstate commerce until completed in the subscribers' offices, and that an order of a Massachusetts commission, requiring the companies to cease discriminating against a would-be subscriber whom the Exchange disapproved was a direct interference with such commerce not sanctioned under the police power of the state or its power over streets crossed by the telegraph which infringed the constitutional right of the companies and those of the Exchange.

224 Mass. 365 reversed.

The cases are stated in the opinion.
