Coach Harold Ulen's Varsity mermen will have a tough battle with the Brown swimmers tonight at 8.30 o'clock in the Indoor Athletic Building, while the Crimson Freshmen will vie with Brown's '38 tankmen, at 7.30 o'clock.

Both the Crimson and Brown Varsity teams turned Dartmouth back by a 37-34 score. The most dangerous competitor that the Harvard forces will face is Captain Fred Lee, former Boston Boy Club swimmer who has performed brilliantly this season.

Henry Fitts., the outstanding candidate for the Intercollegiate diving title, is lost to the Crimson team through scholastic difficulties, and Lyman, Brown's star diver, may pick up several points in this event.

Freshmen Powerful

With only one setback this season, the powerful Freshman swimmers will take the water against Brown this evening at 7.30 o'clock in the Indoor Athletic Building. In the last three meets the Crimson natators have smashed a record or two each time.
