"Yes," replied Heliobas, calling the dog, who went to him immediately to be fondled. "I should never have been much encouraged in my researches, had he not been at hand. I feared to experimentalize much on my sister, she being young at the time—and women are always frail of construction—but Leo was willing and ready to be a victim to science, if necessary. Instead of a martyr he is a living triumph—are you not, old boy?" he continued, stroking the silky coat of the animal, who responded with a short low bark of satisfaction.
My curiosity was much excited by these remarks, and I said eagerly:
"Will you tell me in what way Leo has been useful to you? I have a great affection for dogs, and I never tire of hearing stories of their wonderful intelligence."
"I will certainly tell you," replied Heliobas. "To some people the story might appear improbable, but it is perfectly true and at the same time simple of comprehension. When I was a very young man, younger than Prince Ivan, I absorbed myself in the study of electricity—its wonderful powers, and its various capabilities. From the consideration of electricity in the different forms by which it is known to civilized Europe, I began to look back through history, to what are ignorantly called 'the dark ages,' but which might more justly be termed the enlightened youth of the world. I found that the force of electricity was well understood by the ancients—better understood by them, in fact, than it is by the scientists of our day. The 'MENE, MENE, TEKEL, UPHARSIN' that glittered in unearthly characters on the wall at Belshazzar's feast, was written by electricity; and the Chaldean kings and priests understood a great many secrets of another form of electric force which the world to-day scoffs at and almost ignores—I mean human electricity, which we all possess, but which we do not all cultivate within us. When once I realized the existence of the fact of human electric force, I applied the discovery to myself, and spared no pains to foster and educate whatever germ of this power lay within me. I succeeded with more ease and celerity than I had imagined possible. At the time I pursued these studies, Leo here was quite a young dog, full of the clumsy playfulness and untrained ignorance of a Newfoundland puppy. One day I was very busy reading an interesting Sanskrit scroll which treated of ancient medicines and remedies, and Leo was gambolling in his awkward way about the room, playing with an old slipper and worrying it with his teeth. The noise he made irritated and disturbed me, and I rose in my chair and called him by name, somewhat angrily. He paused in his game and looked up—his eyes met mine exactly. His head drooped; he shivered uneasily, whined, and lay down motionless. He never stirred once from the position he had taken, till I gave him permission—and remember, he was untrained. This strange behaviour led me to try other experiments with him, and all succeeded. I gradually led him up to the point I desired—that is, I FORCED HIM TO RECEIVE MY THOUGHT AND ACT UPON IT, as far as his canine capabilities could do, and he has never once failed. It is sufficient for me to strongly WILL him to do a certain thing, and I can convey that command of mine to his brain without uttering a single word, and he will obey me."
I suppose I showed surprise and incredulity in my face, for Heliobas smiled at me and continued:
"I will put him to the proof at any time you like. If you wish him to fetch anything that he is physically able to carry, and will write the name of whatever it is on a slip of paper, just for me to know what you require, I guarantee Leo's obedience."
I looked at Zara, and she laughed.
"It seems like magic to you, does it not?" she said; "but I assure you it is quite true."
"I am bound to admit," said Prince Ivan, "that I once doubted both Leo and his master, but I am quite converted. Here, mademoiselle," he continued, handing me a leaf from his pocket-book and a pencil—"write down something that you want; only don't send the dog to Italy on an errand just now, as we want him back before we adjourn to the drawing-room."
I remembered that I had left an embroidered handkerchief on the couch in Zara's room, and I wrote this down on the paper, which I passed to Heliobas. He glanced at it and tore it up. Leo was indulging himself with a bone under the table, but came instantly to his master's call. Heliobas took the dog's head between his two hands, and gazed steadily into the grave brown eyes that regarded him with equal steadiness. This interchange of looks lasted but a few seconds. Leo left the room, walking with an unruffled and dignified pace, while we awaited his return—Heliobas and Zara with indifference, Prince Ivan with amusement, and I with interest and expectancy. Two or three minutes elapsed, and the dog returned with the same majestic demeanour, carrying between his teeth my handkerchief. He came straight to me and placed it in my hand; shook himself, wagged his tail, and conveying a perfectly human expression of satisfaction into his face, went under the table again to his bone. I was utterly amazed, but at the same time convinced. I had not seen the dog since my arrival in Paris, and it was impossible for him to have known where to find my handkerchief, or to recognize it as being mine, unless through the means Heliobas had explained.
