Air. Lawson continued today to defy the committee, refusing over and over again to give the names of the men he said he had been told pro-toted by the "leak" after suggesting that he could name an official higher up than anyone yet mentioned. Four motions to cite him before the bar of the House for contempt, pending when he left the witness stand early in the day, were considered by the committee in executive session. No decision was reached, but some of the members indicated later that Mr. Lawson probably would not be recalled, and that if it was determined to report the Wood resolution unfavorably, the contempt charges would be forgotten.

In the meantime, the financier remains in Washington, subject to the committee's orders.

The hearing will continue throughout tomorrow, at least, to give several of the men mentioned in the various reports and rumors related before the committee an opportunity to make statements.

Hiring today's examination, Mr. Lawson frankly admitted that he was not particularly concerned with the so-called "leak" itself, but that his purpose in agitating the subject primarily was to bring about a thorough investigation of the New York Stock Exchange that would lead to incorporation and Federal regulation.
