The round robin of the scrub baseball series will begin tomorrow afternoon at 4 o'clock. Changes in the members of the teams may now be made with the consent of the managers. Each captain is required to hand in a list of 14 men who will comprise his team for the series at the CRIMSON Office before noon today. After that time no changes under any circumstances will be allowed. Failure to comply with this rule will mean the forfeiture of a game for each change.
