Mr. Hogan addressed both the House and Senate chambers at their leaders' invitation — a customary courtesy afforded newly elected governors — but his reception was notably warm. House Speaker Michael E. Busch went to elaborate lengths to make the point that he intended to work collaboratively with the Republican executive. He introduced Mr. Hogan by pointing out to the delegates that they all had small Maryland flags on their desks, a powerful symbol, he said, of two sides coming together. The flag's distinctive design, he said, melds the yellow and black crest of the Calvert family with the red and white of the Crosslands. During the Civil War, the yellow and black became the symbol of Unionists, and the red and white was adopted by those who favored secession. In the 1880s, the two started appearing together in one flag, notably, Mr. Busch said, during the 25th anniversary commemoration of the Battle of Gettysburg. "It was the coalition of two different philosophies," he said. "Here, every four years we bring both sides back together in the same symbolic gesture that flag represents."
