For many years she has known and admired Miss Barton and against the advice of her friends had resolved to help Miss Barton in her task of succoring the sufferers in Cuba. During the second day's fighting Mrs. Porter, escorted by a general whom she has known for many years, rode almost to the firing line. Bullets whistled about her head, but she rode bravely on until her curiosity was satisfied. Then she rode leisurely back to safety. She came back filled with admiration of the colored troops. She described them as being "brave in battle, obedient under orders and philosophical under privations." Thanks to Mrs. Porter, the wife of the President's private secretary. Mrs. Porter is one of heaven's blessings, sent as a messenger of "The Ship" earth, to testify in America what she saw of the Negro troops in Cuba. * * * * * THE INVESTMENT OF SANTIAGO AND SURRENDER. (As Presented in the N.Y. World.) General Shafter put a human rope of 22,400 men around Santiago, with its 26,000 Spanish soldiers, and then Spain succumbed in despair. In a semi-circle extending around Santiago, from Daliquiri on the east clear around to Cobre on the west, our troops were stretched a cordon of almost impenetrable thickness and strength. First came General Bates, with the Ninth, Tenth, Third, Thirteenth, Twenty-first and Twenty-fourth U.S. Infantry. On his right crouched General Sumner, commanding the Third, Sixth and Ninth U.S. Cavalry. Next along the arc were the Seventh, Twelfth and Seventeenth U.S. Infantry under General Chaffee. Then, advantageously posted, there were six batteries of artillery prepared to sweep the horizon under direction of General Randolph. General Jacob Kent, with the Seventy-first New York Volunteers and the Sixth and Sixteenth U.S. Infantry, held the centre. They were flanked by General Wheeler and the Rough Riders, dismounted; eight troops of the First U.S. Volunteers, four troops of the Second U.S. Cavalry, four light batteries, two heavy batteries and then four more troops of the Second U.S. Cavalry.
