Forced inside by a cold, drizzling, New England rain Harvard's football squad sought shelter in the Briggs baseball cage yesterday afternoon in opening its final week of practice of the 1929 season.

Because of the inadequacy of the cage the practice was extremely light. The nature of the workout was not revealed other than that the squad listened to a blackboard talk by Coach Horween and after individual instructions three teams ran through a 45-minute signal drill. Whether or not the squad received some more new plays was not divulged.

It is certain however that, after Saturday's performance, Harvard needs a power play which it can use when near the enemy goal line. It is possible that several slight changes will be made in the semi-kick formation which the Crimson has used in its last few games in order to provide Coach Horween's men with a play that will click at the critical moment.

All men except Potter, who is out of the game with a foot injury, reported in fine condition yesterday. Trainer was given a day off and was in the cage in civilian clothes watching Richards take his place at guard. Except for this temporary change the first team lined up exactly as it has since the Michigan game.

The entire squad will be given a complete respite from hard work today when all 34 men and the entire coaching staff will motor to the Myopia Hunt Club for a day of rest. The squad will leave at 2 o'clock and will not return until late in the evening. A possible light workout may be in order if the weather is suitable. Tomorrow and Thursday Coach Knox's seconds will put on a demonstration of Yale plays and Coach Knox and Harper will give their impressions of the Blue team. Knox has scouted every Yale game since the Harvard-Army tussel while Harper watched the Bulldog-Tiger clash last Saturday while enjoying a rest from active work.
