It has always been supposed that the piece of property bounded by Quincy and Harvard streets, Cambridge and North Avenue, belonged to Harvard University, and was for the use of those connected with that institution. The citizens of Cambridge have been admitted by courtesy and allowed to pass through at any time of day or night. But we begin to doubt the ownership of the college property when we see the part between the college library and Harvard street literally infested with Cambridge muckers. These young ragamuffins cluster there by hundreds almost every afternoon, and even at night; and they make pedestrianism on the path to the library an exceedingly dangerous undertaking by swooping down the hill on their bobsleighs and barrel-staves. They come, too, in such rapid succession that it requires skill and coolness to dodge them. Added to this, they make day and night hideous with their hoots and yells, and must be extremely unpleasant neighbors to the inmates of Dr. Peabody's and President Eliot's houses. Why we should be called upon to tolerate such unmitigated nuisances right in our midst is rather difficult of comprehension. We appeal to those who have authority in the matter, whosoever they may be. Are we to run serious risks of having our arms, legs or head smashed by a lot of careless, dare-devil youngsters? A policeman or two, hired by the college, would very soon put an end to the nuisance. Let up hope the hint will be taken.
