The Class of 1934 invaded the Essex County Club yesterday for the high point for the reunioning classmates, their families, and their guests. A crowd of 1400 was kept constantly occupied by swimming, golf, tennis, exhibitions, sightseeing, eating, drinking, conversation, or just looking around.

Class members and friends whipped through 1400 lobsters, each of which weighed in at 1 1/2 pounds. The head caterer, now in his fifteenth year serving hungry alumni at Essex, watched '34 eat up 250 pounds of chicken salad, 300 quarts of sherbet, and 125 gallons of coffee. His firm also fed 500 younger children of the Class at their own picnic at Manchester Beach.

In the even more popular alcohol department, the guests have consumed 75 cases of liquor and 300 cases of beer and ale thus far in the reunion. Yesterday 22 bartenders were busy keeping the Class of '34 happy--and happier and happier.

An army of 47 MTA buses herded the crowds to the Club for a full day's activities and dancing at night. During the day some families took bus trips to nearby Manchester Yacht Club, to Salem for an historical tour, or to Singing Beach. There a few brave souls, who, according to the class clown, "will never make their 50th., swam in 58 degrees ocean surf. On the links, E. Howard Roorbach, with a gross 82, and William T. Piper Jr., with a 33 putting score, took honors for the day.

The classmates who tried their tired muscles on softball were beaten by their college-age sons, but one loser consoled the team by saying that the old men did not have to buy drinks for the losers, because everything was gratis at the Essex.

The Class of 1934 will not stop here; "The University Today" panels and the traditional class picture will occupy another active morning today. The Class Luncheon will be held at noon; then the Class will lead the parade to the Harvard-Yale baseball game at 3 p.m.
