If custom can be expected for the 52nd time, the first wave of Dartmouth men will hit Cambridge tonight. Chief Randall's University police are already aware of the impending invasion, but they don't expect any trouble. Only five Yard police will be on duty.

Freshmen residing in the Yard are not as optimistic as the police, and vigilante committees have been formed in most halls to repel the Indians. The men in Weld and Matthews Halls will devote most of their attention to holding Dartmouths bent on dousing the statue of John Harvard with green paint.

Real Estate chief James Biggar was unimpressed by the coming of the Big Green. "They seldom do very much. The last real trouble we had was when some M.I.T. students painted T-E-C-H on Widener's pillars," he said.

Only one remnant of last year's as sault is still visible in Cambridge, a large green "D" emblazoned on the Eliot House end of the Larz Anderson bridge.

But persistent rumors coming down from the North warn of great plans being made up in Hanover. The intensity of this campaign is certainly increased by the failure of the 1947 operation. A combination of a forest fire in New Hampshire which grounded all Indian warriors, and a sudden CRIMSON expose of the entire plot demolished such grandiose schemes as dyeing the Charles River green.
