In this same year--1884--no fewer than three explosions occurred on the night of the 30th May, whilst on the same evening a bag was found in Trafalgar Square containing Atlas Powder, with fuse and detonators. The first was at the Junior Carlton Club, St. James's Square, where about fourteen persons were injured. The second--which occurred about fifteen seconds after that at the Junior Carlton--at the residence of Sir Watkin Williams-Wynn, St. James's Square (Fig. 18), which the perpetrators evidently mistook for a part of the Intelligence Office. It is probable that the charge used was thrown over the area railings, but it accidentally lodged in a window recess of the morning room, where the most serious effects of the explosion were felt, although the windows of the house were much shattered. As the official report states:-- [Illustration: FIG. 19.--SIR WATKIN WILLIAMS-WYNN'S--MORNING ROOM.] "Although a party were assembled in the morning-room at the time the explosion occurred, they fortunately escaped injury with the exception of one lady, who had her hand slightly cut by some broken glass. This remarkable escape (as it must appear to anyone who had an opportunity of examining the room before the _débris_ had been disturbed, or who has seen the photographs of this room) can only be attributed to the fact that the party did not happen to be seated directly opposite to the window under which the explosion occurred, but rather in the other part of the room, where they were to some extent sheltered from the effects (Fig. 19). Two servants who were standing on the front doorstep were also injured, one of them somewhat severely, making a total, so far as is known, of three persons injured by this explosion." [Illustration: FIG. 20.--EXPLOSION AT SCOTLAND YARD.] The third explosion of this eventful night took place at 9.20 p.m., at Old Scotland Yard. The charge was placed outside a room used by some of the detective staff. The explosion brought down a portion of the building, doing considerable damage to some carriages standing there at the time and to neighbouring buildings, and injuring several persons (Figs. 20 and 21).
