7月28日 星期日 杭州侵晓大雨,有雷。下午睛。晚29° 中午,绍兴旅杭同乡会请绍兴专员郑小隐、县长林泽。

晨六点起。大雨不止,平地尽成泽国。阅来往信件四十余件。十点前农学院(东大)毕业杨继义来,现在江西办青年军就业训练班农业部份,地点在江西铅山。

此次偕青年军卅一车政治部副主任黄贤虔来,道中谓在绿杨新村及净寺办理法律、交通、师范、电机等各班训练班,请介绍人才。中午据次廉报告,谓省立图书馆有保安队兵士一总队开入居住。余于中膳即嘱皮高品往图书(馆)告兵士以该屋已有省政府交与浙大,不日修理,不能居住。一方嘱杨次廉去接洽队长。余睡一小时后,三点即偕季梁至岳坟前市政府小学地址看地。此处有地一亩八分,可以建筑师范学院之学生宿舍,但沿湖长不达一百码。四至圣塘路晤丝鸣涛,嘱令宪兵搬走。
