At last the wished-for Saturday arrived. It was one of those clear, bracing days that always put every one in good-humor. Though cool, it was not too cool for the comfort of the girls and older women who were to sit for two or three hours in the open air. Every car running to Cambridge carried a double load, with men and boys crowding the platform in dangerous fashion. Carriages of every description were rushing over the long bridge between Boston and the University City and not only were red or orange flags to be seen waving on every side--small flags that could be easily folded up, but occasionally some group of youths would break out into the college cry.
