Judge Dawson had ample discretion to dismiss plaintiff’s action when plaintiff did not appear for trial at the time previously set in pre-trial conference. F.R.Civ.P. 41(b); Joseph v. Norton Co., 2 Cir., 273 F.2d 65. Additionally the disclosures at the conference showed that plaintiff had no claim; the advertising “plan” which he volunteered to send the defendant contained nothing which was not common knowledge. Soule v. Bon Ami Co., 201 App.Div. 794,195 N. Y.S. 574, affirmed 235 N.Y. 609, 139 N.E. 754; Masline v. New York, N. H. & H. R. Co., 95 Conn. 702, 112 A. 639.

Affirmed.
