Paul H. Butler, Democratic National Chairman, will deliver one of the opening addresses at the Intercollegiate Mock Convention May 11 sponsored by the Young Democratic Club, newly elected president, Gordon A. Martin, Jr. '57, announced yesterday.

The HYRC hopes to have at least two other prominent Democrats appear before its two-day convention, Martin said.

Besides Martin, other major officers elected last week were Robert B. Hill '57 of North Little Rock, Ark, and Dunster House, vice-president; George H. Shapiro '58 of Atlanta, Ga. and Dunster House, bulletin editor; David N. Smith '58 of Saranac Lake, N.Y. and Kirkland House, treasurer; and Joseph L. Heisler, Jr. '57 of Wayne, Pa. and Winthrop House, secretary.
