Threats preceded deeds. The final years of the emperor's life were made wretched through fear and anxiety. His ministers were killed by the revolutionists. Some of the guards placed about his person became victims of the secret band. Letters bordered with black and threatening the emperor's life were found among his papers or his clothes. An explosive powder placed in his handkerchief injured his sight for a time; a box of asthma pills sent him proved to contain a small but dangerous infernal machine. He grew haggard through this constant peril; his hair whitened, his form shrank, his nerves were unstrung.

In February, 1879, Prince Krapotkin, governor-general of Kharkoff, was killed by a pistol-shot fired into his carriage window. In April a Nihilist fired five pistol-shots at the czar. In June the Nihilists resolved to use dynamite with the purpose of destroying the governors-general of several provinces and the czar and heir-apparent. Among their victims was the chief of police, while two of his successors barely escaped death.

The first attempt to kill the czar by dynamite took the form of excavating mines under three railroads on one of which he was expected to travel. Of these mines only one was exploded. A house on the Moscow railroad, not far from that city, was purchased by the conspirators, and an underground passage excavated from its cellar to the roadway. Here auger-holes were bored upward in which were inserted iron pipes communicating with dynamite stored below. On the day when the emperor was expected to pass, a woman Nihilist named Sophia Perovskya stood within view of the track, with instructions to wave her handkerchief to the conspirators in the house at the proper moment. The pilot train which always preceded the imperial train was allowed to pass. The other train drew up to take water, and was wrecked by the explosion of the mine. Fortunately for the emperor, he was in the pilot train and out of danger.

Some of the participants in this affair were arrested, but their chief, a German named Hartmann, escaped. Despite the utmost efforts of the police, he made his way safely out of Russia, aided by Nihilists at every step, sometimes travelling on foot, at other times in peasants' carts, finally crossing the frontier and reaching the nest of conspirators at Geneva. Here he is supposed to have taken part with others in devising a new and what proved a fatal plot. Meanwhile a fresh attempt was made on the life of the czar.

On February 5, 1880, Alexander II. was to entertain at dinner in the Winter Palace a royal visitor, Prince Alexander of Hesse. Fortunately, the czar was detained for a short time, and the hour fixed for the dinner had passed when the party proceeded along the corridor to the dining-hall. The brief delay probably saved their lives, for at that moment a tremendous explosion took place, wrecking the dining-hall and completely demolishing the guard-room, which was filled with dead and dying victims, sixty-seven in all. It proved that a Nihilist had obtained employment among some carpenters engaged in repairs within the palace, and had succeeded in storing dynamite in a tool-chest in his room. He escaped, and was never seen in St. Petersburg again. Two days later the corpse of a murdered policeman was found on the frozen surface of the Neva, a paper pinned to his breast threatening with death every governor-general except Melikoff, the successor of the murdered Krapotkin.

Their failures had proved so nearly successes that the Nihilists were rather encouraged than depressed. New plans followed the failure of old ones. It was proposed to poison the emperor and his son, the murder to be followed by a revolt of the disaffected in Moscow and St. Petersburg, the seizure of the palaces, and the establishment of a constitutional government. This plan, however, was given up as not likely to have the "great moral effect" which the Nihilists hoped to produce.

A Nihilist student in St. Petersburg had sent to the Paris committee of the society a recipe for a formidable explosive of his invention. A quantity of this dangerous substance was manufactured in France and secretly conveyed to St. Petersburg, where bombs to contain it had been prepared. The plans of the conspirators were now very carefully laid. They did not propose to fail again, if care could insure success. A cheesemonger's shop was opened on a street leading to the palace, under which a mine was laid to the centre of the carriage-way, it being proposed to kill the czar when out driving. If his carriage should take another route and follow the street leading from the Catharine Canal, it was arranged to wreck it with bombs flung by hand. The death of the czar was the sole thing in view. The conspirators seemed willing freely to sacrifice their own lives to that object. As regards the mine, it was so heavily charged with dynamite that its explosion would have wrecked a great part of the Anitchkoff Palace while killing the czar.

How the explosive material was conveyed from Paris to Russia is a mystery which was never successfully traced by the police. The utmost care was taken at the frontiers to prevent the entrance of any suspicious substance. For a year or two even the tea that came on the backs of camels from China was carefully searched, while all travellers were closely examined, and all articles coming from Western Europe were almost pulled to pieces in the minuteness of the scrutiny. The explosive is said to have looked like golden syrup, and to have been sweet to the taste, though acrid in its after-effects. A drop or two let fall on a hot stove flashed up in a brilliant sheet of flame, though without smell or noise.
