BATS UPSET KOUSSY AS BERG'S CONCERTO DRIVES THEM OUT

After a report that bats in Sanders Theatre had disturbed Dr. Serge Koussevitzky during the Boston Symphony's concert Thursday evening. Colonel Apted and the Memorial Hall janitor were on the alert yesterday for any sign of the black denizens.

Apparently undisturbed by the Symphony's usual productions, the bats remained dormant during the first number. But Alban Berg's Violin Concerto, second on the program, brought them out in full force. The birds searched frantically for an exit. Scratching and squeaking could be heard throughout the concerto in the dim upper recesses of the hall.

In discussing the problem of extermination, Colonel Apted admitted, "It's not exceptional to have more than one kind of bat in Sanders."
