There was no doubt whatever as to the reality of this unknown terror of the deep, for several vessels had been struck by it, and particularly the Cunard steamer Scotia, homeward bound for Liverpool.  It had pierced a large triangular hole through the steel plates of the Scotia’s hull, and would certainly have sunk the vessel had it not been divided into seven water-tight compartments, any one of which could stand injury without danger to the vessel.  It was three hundred miles off Cape Clear that the Scotia encountered this mysterious monster.  Arriving after some days’ delay at Liverpool, the vessel was put into dock, when the result of the blow from the unknown was thoroughly investigated.  So many vessels having recently been lost from unknown causes, the narrow escape of the Scotia directed fresh attention to this ocean mystery, and both in Europe and America there was a strong public agitation for an expedition to be sent out, prepared to do battle with, and if possible destroy, this narwhal of monstrous growth, as many scientists believed it to be.

Now I, Pierre Arronax, assistant professor in the Paris Museum of Natural History, was at this time in America, where I had been engaged on a scientific expedition into the disagreeable region of Nebraska.  I had arrived at New York in company of my faithful attendant, Conseil, and was devoting my attention to classifying the numerous specimens I had gathered for the Paris Museum.  As I had already some reputation in the scientific world from my book on “The Mysteries of the Great Submarine Grounds,” a number of people did me the honour of consulting me concerning the one subject then exercising the minds of all interested in ocean travel.

An expedition was also being fitted out by the United States government, the fastest frigate of the navy, the Abraham Lincoln, under command of Captain Farragut, being in active preparation, with the object of hunting out this wandering monster which had last been seen three weeks before by a San Francisco steamer in the North Pacific Ocean.  I was invited to join this expedition as a representative of France, and immediately decided to do so.  The faithful Conseil said he would go with me wherever I went, and thus it came about that my sturdy Flemish companion, who had accompanied me on scientific expeditions for ten years was with me again on the eventful cruise which began when we sailed from Brooklyn for the Pacific and the unknown.

The crew of the frigate and the various scientists on board were all eagerness to meet the great cetacean, or sea-unicorn.  My own opinion was that it would be found to be a narwhal of monstrous growth, for these creatures are armed with a kind of ivory sword, or tusk, as hard as steel, and sometimes nearly seven feet long by fifteen inches in diameter at the base.  Supposing one to exist ten times as large as any that had ever been captured, with its tusk proportionately powerful, it was conceivable that such a gigantic creature, moving at a great rate, could do all the damage that had been reported.
