C., Minneapolis. G. A. BRACKETT, " The list is headed by Ex-Governor Smith, President of the Northern Pacific Railroad and of the Vermont Central. It fell to his lot to be Chief Magistrate of the Green Mountain State during the rebellion, and among all the loyal governors there was no one that excelled him in energy and executive force. He was here, there, and everywhere,--one day in Vermont, the next in Washington, the third in the rear of the army looking after the wounded. I remember seeing him at Fredericksburg during those terrible weeks that followed the struggles at the Wilderness and Spottsylvania,--directing his assistants, laboring with his own hands,--hunting up the sick and wounded, giving up his own cot, sleeping on the bare floor, or not sleeping at all,--cheering the despondent, writing sympathetic letters to fathers and mothers whose sons were in the hospital, or who had given their lives to their country. He has taken hold of this great enterprise--the construction of a railroad across the continent from the Lakes to the Pacific Ocean--with like zeal and energy, and has organized this expedition to explore the country between Lake Superior and the Missouri River. Judge Rice is from Maine. He is President of the Portland and Kennebec Railroad, and a director of the Northern Pacific. Before engaging in the management of railroads he held, for sixteen years, the honorable and responsible position of Associate Judge of the Supreme Court of Maine. Well versed in law, and holding the scales of justice evenly, his decisions have been regarded as wise and just. Mr. Johnson is the Chief Engineer of the road, one of the ablest in his profession in the country. As long ago as 1853, before the government surveys were made, he published a pamphlet upon this future highway to the Pacific, in which he discussed with great ability the physical geography of the country, not only from Lake Superior to Puget Sound, but the entire region between the Mississippi and the Pacific. The explorations that have since been made correspond almost exactly with his statements.
