New Haven, Conn., May 30--Breaking loose from all civic and college restraint in a spectacular celebration of "Bottle Night" last evening, nearly 300 Yale undergraduates stormed street-cars and the police-station in the center of New Haven and necessitated a riot-call to restore order in the city.

The noise of a suction street-sweeper engaged in nocturnal activity near Harkness Hall provided the incentive for the demonstration. A group of students resented the presence of the machine and attempted to halt its progress. In the ensuing disorder, street-cars were besieged, and their trolleys disconnected. One of the Yale men was speedily arrested and led jail-wards, but this act served only to center the attention of the crowd upon the police officers and a force of rescuers marched in pursuit of the captive. A frontal assault upon the New Haven police headquarters, covered by a brief barrage of brick-bats, was repulsed with the loss of several more prisoners. Still unqualified, the student forces dispatched skirmish parties to create a diversion. This was done effectively by the turning in of a false fire alarm.

The beleaguered patrolmen scored a sudden and overwhelming victory at this point by calling in reserves from the suburbs and charging the mob with drawn night-sticks. When the smoke had cleared, six students were on the inside looking out, with more arrests in prospect.

"Bottle Night" is an annual Yale clean-up demonstration. Dormitory inmates assemble at opened casements to hurl the season's collection of bottles, kickshaws, flotsam and jetsam out on the campus to be carted away the following morning.
