Washington, Nov. 12—Activities on ‘‘rum row” of vessels under the Norwegian flag, reported by the coast guard service yesterday, will be investigated by the Norwegian minister here. H. H. Bryn.

Mr. Bryn said today he would ask the American government to furnish him with the names of these ships in order that he might communicate the facts to the Norwegian foreign office.

The minister added that popular opinion In Norway, which is itself a prohibition country, would oppose the use of the Norwegian flag for smuggling liquor into the United States. He expressed confidence that the Norwegian Ship Owners’ Association would take steps to correct any such situation as pointed out in the coast guard report.
