In the evil-smelling darkness of the Victory Theater on Washington Street, a well-balanced program is being shown these days. While one picture demonstrates graphically the dangers of Ceylon rural life, the other is equally disenchanting about our own urban civilization. But for the man who does not give a hang for the sociological view, and merely wants to be entertained, both features are the nuts.

Against a background of pythons, armadilloes, vampire-bats, and other interesting fauna, the protagonists of "Jungle Virgin" give a new, exciting, neolithic twist to the love-triangle, the title character keeping her dubious claim largely because the outside corner, a real cad, confines himself to the oldfashioned bear hug. Tita, an uncommonly puny hero, though ferocious enough when need be, finally finds the villain making advances in a tree, after having kidnapped a baby elephant. He makes a brilliant tackle, and all ends happily when the villain falls into the paws of a conveniently waiting leopard. As far as anyone knows, the jungle virgin lives happily as such ever after.

But "Teen Age" is an altogether different story. Through its stormy plot are implied all sorts of juiey vices, picturing rather well the joys of full-seale juvenile delinquency. Judging from the ladies' hats and the chorus girls' tights, this opns was first seen around 1931, and unconsciously it captures the unhygienic lustiness of that time, still faintly present on the Old Howard stage. And tied in with the delicious mclee of gambling dens, steamy nightclubs, and amateur acrobaties, is a moral: "Parents, look after your children." A portly district attorney propounds this unconventional view repeatedly, and happily has the opportunity to illustrate its validity with flashbacks. Then somehow or other the movie ends.

With entertainment at a premium in summery Boston, it is good to be able to fasten on something worthwhile. And "Jungle Virgin" and "Teen Age" can be enjoyed, one way or another. There are also some shorts, but better not talk about that.
