We have been obliged to complain many times in our columns of the disgraceful way in which the Cambridge "muckers" are allowed to take possession of the college yard and athletic grounds. As the spring has advanced the nuisance has been getting more and more intolerable, and must be stopped in some way. The new sod in the yard is trampled all over every day by these irrepressible youngsters; they gather in swarms whenever the Glee Club sings, and on Wednesday they used Holmes Field as a play-ground while the cricket match was going on, got in everybody's way, and yelled and hooted like young demons. Not content with this, a crowd of them took possession of Jarvis Field and played a game of base-ball there, refusing to give up the grounds to some students who wished to practice. It is small use for the college authorities to hang out a sign warning all but Harvard students to keep off Holmes field; let them take active measures. A regularly employed watchman to patrol the yard and the athletic grounds would cost very little during the spring and autumn months in comparison with the benefit which would result to the college. If the college authorities will not keep the college property free from such pests, then the students must take the matter in hand. It is a burning shame that students of such a college as this should be subjected to such treatment. At Yale there is a college police force, and one never hears of such intrusions upon college rights there. If it is beneath our boasted Harvard dignity to form ourselves into a police force, then we must suffer, for apparently we shall get no help elsewhere. But if a few determined men would get together and make up their minds not to allow the nuisance to go further, the Cambridge "muckers" and other objection-able characters would soon learn to know their natural sphere and to remain there.
