Authorities Say Air Alarm Test "Highly Satisfactory"

Results of the air-raid test from the roof of Widener Wednesday noon were "highly satisfactory in and beyond the area that we were trying to cover," said officials of the Eastern Company who conducted the trial.

Listeners in Central Square and even in Fen way in Boston reported that they had heard the alarm system. Company officials also were pleased by the way in which the unusual tone of the siren was noticed; for one of their big problems, besides devising a frequency that would be heard above the sounds of traffic, was to make the tone different from any other siren or fog horn.

In reply to the statement of a Boston paper that merchants in the Square had not even heard the alarm, the Eastern Company said that the purpose of the siren was to get people off of the streets, not bring them out. The Eastern Company is supplying the City of Cambridge with the apparatus.
