Niagara Falls. N. Y.. Feb 12 Despite the strict censorship which has been imposed by the Canadian authorities on the dispatch or publication of news of a military nature, information from reliable sources was received here today of hurried precautions taken at Niagara Falls, Ontario, Friday, to resist a threatened "invasion by German forces" from the American side. A force of soldiers, estimated at 500 men, and three machine-gun squads were rushed there from St. Catherine's and placed on guard at the great power plants and the International bridge. The men slept under arms. The report was current that the "army" of Germans was on the way to the Canadian city from Buffalo. There was apparently no foundation for the war scare.
