Ticketing of cars parked in violation of the University rule which prohibits parking in a large area will be continued over the weekend, according to Matthew J. Toohy, Captain of the University Police.

In the past, many students with cars have left them on the streets Sunday morning after returning late from a Saturday night date. According to Toohy, the entire area will be covered again tonight by teams of University policemen, and the policy will continue until the summer recess.

Meanwhile, the number of student cars found within the bounds of the proscribed area has been decreasing nightly. On Tuesday, the first night of large-scale ticketing, 75 student cars were tagged. Wednesday night, 30 were tagged, while Thursday night only 12 student cars were found illegally parked.

The number of cars without Harvard registration stickers parked in the area has been increasing, however, a fact which may mean that students are removing stickers rather than moving cars. Captain Toohy warned yesterday that the license numbers of all cars without stickers, or with unreadable stickers, are being checked.

Spaces at the Business School lot are being rented at a rapid rate, according to police officials. More than 60 spaces were available last week; only a dozen of these were left yesterday. Almost all of the rented spaces are being used, reports of the night watchman indicate. In addition, streets beyond the edges of the restricted area have shown an increasing number of cars. These streets may eventually be included in the ban, officials said on Thursday.

Toohy also requested yesterday that students belonging to the Owl and Fly clubs avoid parking on the sidewalks bordering Holyoke Place during the weekend, so that cars coming to the Lowell House Opera can get through the streets.
