JOSEPH REED (colored).--This was a lad of seven years of age, residing at No. 147 East Twenty-eighth Street, with an aged grandmother and widowed mother. On Wednesday morning of the fearful week, a crowd of ruffians gathered in the neighborhood, determined on a week of plunder and death. They attacked the house, stole everything they could carry with them, and, after threatening the inmates, set fire to it. The colored people who had the sole occupancy of the building, fled in confusion into the midst of the gathering crowd. And then the child was separated from his guardians. His youth and evident illness, even from the devils around him, it would be thought, should have insured his safety. But no sooner did they see his unprotected, defenceless condition, than a gang of fiendish men seized him, beat him with sticks, and bruised him with heavy cobblestones. But one, tenfold more the servant of Satan than the rest, rushed at the child, and with the stock of a pistol struck him on the temple and felled him to the ground. A noble young fireman, by the name of John F. Govern, of No. 39 Hose Company, instantly came to the rescue, and, single-handed, held the crowd at bay. Taking the wounded and unconscious boy in his arms, he carried him to a place of safety. The terrible beating and the great fright the poor lad had undergone was too much for his feeble frame; he died on the following Tuesday. JOSEPH JACKSON (colored), aged nineteen years, living in West Fifty-third Street, near Sixth Avenue, was in the industrious pursuit of his humble occupation of gathering provender for a herd of cattle, and when near the foot of Thirty-fourth Street, East River, July 15, was set upon by the mob, killed, and his body thrown into the river. SAMUEL JOHNSON (colored).--On Tuesday night Johnson was attacked near Fulton Ferry by a gang who mercilessly beat and left him for dead. A proposition was made to throw him into the river, but for some reason the murderers took fright and fled. He was taken by some citizens to his home, and died the next day. ---- WILLIAMS (colored).--He was attacked on the corner of Le Roy and Washington Streets, on Tuesday morning, July 14th, knocked down, a number of men jumped upon, kicked, and stamped upon him until insensible. One of the murderers knelt on the body and drove a knife into it; the blade being too small, he threw it away and resorted to his fists. Another seized a huge stone, weighing near twenty pounds, and deliberately crushed it again and again on to the victim. A force of police, under Captain Dickson, arrived and rescued the man, who was conveyed to the New York Hospital. He was only able to articulate "Williams" in response to a question as to his name, and remained insensible thereafter, dying in a few days.
