University oarsmen will row Princeton on the Lake Carnegie two-mile course April 27, and Yale either on the Housatonic or the Charles on June 1, according to the announcement of the University rowing management last night. A 1921 crew will probably meet the Princeton freshmen at Princeton on the former date.

On June 1 the University will meet Yale in races for both first and second crews. At some time before that date the two highest University boats will race each other, and the winning crew will represent the University against a boat similarly chosen at Yale. These two crews will toss for the course, the choice being between the new Housatonic, near New Haven, and the Charles River course. If the first crews race on the Charles the second crews will race on the Housatonic, and vice versa.

The first 1921 crew will race the Yale freshmen on May 25, the place to be decided by a toss. In all cases the course will be two miles.

For the races with both Princeton and Yale the visiting crew will use the home crew's shell. In the latter case alterations in the rigging will be made to allow for the different systems of rowing taught at the University and at Yale and Princeton.

Workout on River Yesterday.

University oarsmen had their first workout on the Charles River yesterday, when two of Coach Brown's crews, the fourth Freshman and a mixed University and Freshman shell had a limited row from Weld up and down the short stretch of open water below the Anderson Bridge. Coach Haines has decided not to put any of the upper crews on the river until the latter part of the week, when it is hoped the launch can follow the crews. However, two more shells will take to the water today. It is expected that by next Monday, when the Newell Boathouse will be opened, that all 16 crews will be put on the Charles.
