Unusual attention has been paid lately to the perils created by the ubiquitous automobile. Local authorities have been engaged for many months in applying the valuable ounce of prevention to various dangerous spots throughout Cambridge, and their installation of "silent policemen" at the intersection of busy streets has greatly reduced catastrophes by cautioning residents and notifying transient strangers of the hazardous crossings.

Cambridge still lacks, however, a beacon at one most important intersection--the blind corner by Jimmie's Lampoon Lunch, where Plympton Street, one of the chief means of local egress from the Metropolitan Parkway, crosses the Mt. Auburn Street artery. The collision which occurred there last evening was trifling, but it is only the long arm of coincidence that has as yet kept the crossing from being the scene of a really tragic accident. This possibility undergraduate drivers realize and they generally approach with some caution, a habit which the majority of passers, either through negligence or ignorance, never acquire.

This intersection of Mt. Auburn Street is quite as dangerous, and quite as much used, as that already marked one block farther down. Last evening's accident was, providentially, only a timely warning and not a tragic lesson, to the Cambridge authorities. The spot should be marked, and, until it is, students will do well to continue to approach it cautiously.
