Mere thoughtlessness or ignorance can not be the least justification for the men who continue to run on the sidewalks on North avenue. The captains of the various teams have taken action in the matter so far as the men who are training under them are concerned, so that the running of the teams no longer gives cause for complaint. Individuals who are members of no teams, however, still continue the practice which others with more wisdom have given up. Some time ago the deans of both the College and the Scientific School made a particular request that the rules laid down by the team captains should be observed by all runners on the avenue; yet this request has been so far unheeded that complaints at the office are still frequent. The men who are to blame for this are very seriously to blame. They show a harmful lack of consideration which is utterly inexcusable. No gentleman should feel himself at liberty to profit by neglecting a request with which his fellows whose interests are like his own comply, especially when his neglect is likely to endanger the priveleges of others.
