Perhaps it was that she was a woman, whilst we were men; perhaps it was that she was younger than the rest; perhaps both reasons were effective, each in its own way. At any rate the change was there, and I was happier than I had been through the long journey. All her buoyancy, her tenderness, her deep feeling seemed to shine forth once more; now and again as her father's eyes rested on her, his face seemed to light up.
Whilst we waited for the carts to arrive, Mr. Trelawny took us through the house, pointing out and explaining where the objects which we had brought with us were to be placed. In one respect only did he withhold confidence. The positions of all those things which had connection with the Great Experiment were not indicated. The cases containing them were to be left in the outer hall, for the present.
By the time we had made the survey, the carts began to arrive; and the stir and bustle of the previous night were renewed. Mr. Trelawny stood in the hall beside the massive ironbound door, and gave directions as to the placing of each of the great packing-cases. Those containing many items were placed in the inner hall where they were to be unpacked.
In an incredibly short time the whole consignment was delivered; and the m en departed with a douceur for each, given through their foreman, which made them effusive in their thanks. Then we all went to our own rooms. There was a strange confidence over us all. I do not think that any one of us had a doubt as the the quiet passing of the remainder of the night.
The faith was justified, for on our re-assembling in the morning we found that all had slept well and peaceably.
During that day all the curios, except those required for the Great Experiment, were put into the places designed for them. Then it was arranged that all the servants should go back with Mrs. Grant to London on the next morning.
When they had all gone Mr. Trelawny, having seen the doors locked, took us into the study.
"Now," said he when we were seated, "I have a secret to impart; but, according to an old promise which does not leave me free, I must ask you each to give me a solemn promise not to reveal it. For three hundred years at least such a promise has been exacted from everyone to whom it ws told, and more than once life and safety were secured through loyal observance of the promise. Even as it is, I am breaking the letter, if not the spirit of the tradition; for I should only tell it to the immediate members of my family."
We all gave the promise required. Then he went on:
"There is a secret place in this house, a cave, natural originally but finished by labour, underneath this house. I will not undertake to say that it has always been used according to the law. During the Bloody Assize more than a few Cornishmen found refuge in it; and later, and earlier, it formed, I have no doubt whatever, a useful place for storing contraband goods. 'Tre Pol and Pen', I suppose you know, have always been smugglers; and their relations and friends and neighbours have not held back from the enterprise. For all such reasons a safe hiding-place was always considered a valuable possession; and as the heads of our House have always insisted on preserving the secret, I am in honour bound to it. Later on, if all be well, I shall of course tell you, Margaret, and you too, Ross, under the conditions that I am bound to make."
He rose up, and we all followed him. Leaving us in the outer hall, he went away alone for a few minutes; and returning, beckoned us to follow him.
In the inside hall we found a whole section of an outstanding angle moved away, and from the cavity saw a great hole dimly dark, and the beginning of a rough staircase cut in the rock. As it was not pitch dark there was manifestly some means of lighting it naturally, so without pause we followed our host as he descended. After some forty or fifty steps cut in a winding passage, we came to a great cave whose further end tapered away into blackness. It was a huge place, dimly lit by a few irregular slits of eccentric shape. Manifestly these were faults in the rock which would readily allow the windows be disguised. Close to each of them was a hanging shutter which could be easily swung across by means of a dangling rope. The sound of the ceaseless beat of the waves came up muffled from far below. Mr. Trelawny at once began to speak:
"This is the spot which I have chosen, as the best I know, for the scene of our Great Experiment. In a hundred different ways it fulfils the conditions which I am led to believe are primary with regard to success. Here, we are, and shall be, as isolated as Queen Tera herself would have been in her rocky tomb in the Valley of the Sorcerer, and still in a rocky cavern. For good or ill we must here stand by our chances, and abide by results. If we are successful we shall be able to let in on the world of modern science such a flood of light from the Old World as will change every condition of thought and experiment and practice. If we fail, then even the knowledge of our attempt will die with us. For this, and all else which may come, I believe we are prepared!" He paused. No one spoke, but we all bowed our heads gravely in acquiescence. He resumed, but with a certain hesitancy:
"It is not yet too late! If any of you have a doubt or misgiving, for God's speak it now! Whoever it may be, can go hence without let or hindrance. The rest of us can go on our way alone!"
Again he paused, and looked keenly at us in turn. We looked at each other; but no one quailed. For my own part, if I had had any doubt as to going on, the look on Margaret's face would have reassured me. It was fearless; it was intense; it was full of a divine calm.
Mr. Trelawny took a long breath, and in a more cheerful, as well as in a more decided tone, went on:
"As we are all of one mind, the sooner we get the necessary matters in train the better. Let me tell you that this place, like all the rest of the house, can be lit with electricity. We could not join the wires to the mains lest our secret should become known, but I have a cable her which we can attach in the hall and complete the circuit!" As he was speaking, he began to ascend the steps. From close to the entrance he took the end of a cable; this he drew forward and attached to a switch in the wall. Then, turning on a tap, he flooded the whole vault and staircase below with light. I could now see from the volume of light streaming up into the hallway that the hole beside the staircase went direct into the cave. Above it was a pulley and a mass of strong tackle with multiplying blocks of the Smeaton order. Mr. Trelawny, seeing me looking at this, said, correctly interpreting my thoughts:
"Yes! it is new. I hung it there myself on purpose. I knew we should have to lower great weights; and as I did not wish to take too many into my confidence, I arranged a tackle which I could work alone if necessary."
We set to work at once; and before nightfall had lowered, unhooked, and placed in the positions designated for each by Trelawny, all the great sarcophagi and all the curios and other matters which we had taken with us.
It was a strange and weird proceeding, the placing of those wonderful monuments of a bygone age in that green cavern, which represented in its cutting and purpose and up-to-date mechanism and electric lights both the old world and the new. But as time went on I grew more and more to recognise the wisdom and correctness of Mr. Trelawny's choice. I was much disturbed when Silvio, who had been brought into the cave in the arms of his mistress, and who was lying asleep on my coat which I had taken off, sprang up when the cat mummy had been unpacked, and flew at it with the same ferocity which he had previously exhibited. The incident showed Margaret in a new phase, and one which gave my heart a pang. She had been standing quite still at one side of the cave leaning on a sarcophagus, in one of those fits of abstraction which had of late come upon her; but on hearing the sound, and seeing Silvio's violent onslaught, she seemed to fall into a positive fury of passion. Her eyes blazed, and her mouth took a hard, cruel tension which was new to me. Instinctively she stepped towards Silvio as if to interfere in the attack. But I too had stepped forward; and as she caught my eye a strange spasm came upon her, and she stopped. Its intensity made me hold my breath; and I put up my hand to clear your eyes. When I had done this, she had on the instant recovered her calm, and there was a look of brief wonder on her face. With all her old grace and sweetness she swept over and lifted Silvio, just as she had done on former occasions, and held him in her arms, petting him and treating him as though he were a little child who had erred.
As I looked a strange fear came over me. The Margaret that I knew seemed to be changing; and in my inmost heart I prayed that the disturbing cause might soon come to an end.
