Co-operation is the byword of a successful business venture; without it the best of projects will fail. So it is with success in football. An enthusiastic cheering section, well drilled in their songs and cheers, is of tremendous value to a team; indifference in the stands leads to defeat on the field. Our co-operation this year has been most lamentable. Ignorance of the songs and cheers, together with that all-too-evident Harvard indifference, is the foundation of our early-season faults. Thursday is the night to learn the songs and cheers. The Union must be crowded.
