After breakfast we all adjourned to the cave, where Mr. Trelawny went over, point by point, the position of each item of our paraphernalia.  He explained as he went on why each piece was so placed.  He had with him the great rolls of paper with the measured plans and the signs and drawings which he had had made from his own and Corbeck’s rough notes.  As he had told us, these contained the whole of the hieroglyphics on walls and ceilings and floor of the tomb in the Valley of the Sorcerer.  Even had not the measurements, made to scale, recorded the position of each piece of furniture, we could have eventually placed them by a study of the cryptic writings and symbols.

Mr. Trelawny explained to us certain other things, not laid down on the chart.  Such as, for instance, that the hollowed part of the table was exactly fitted to the bottom of the Magic Coffer, which was therefore intended to be placed on it.  The respective legs of this table were indicated by differently shaped uraei outlined on the floor, the head of each being extended in the direction of the similar uraeus twined round the leg.  Also that the mummy, when laid on the raised portion in the bottom of the sarcophagus, seemingly made to fit the form, would lie head to the West and feet to the East, thus receiving the natural earth currents.  “If this be intended,” he said, “as I presume it is, I gather that the force to be used has something to do with magnetism or electricity, or both.  It may be, of course, that some other force, such, for instance, as that emanating from radium, is to be employed.  I have experimented with the latter, but only in such small quantity as I could obtain; but so far as I can ascertain the stone of the Coffer is absolutely impervious to its influence.  There must be some such unsusceptible substances in nature.  Radium does not seemingly manifest itself when distributed through pitchblende; and there are doubtless other such substances in which it can be imprisoned.  Possibly these may belong to that class of “inert” elements discovered or isolated by Sir William Ramsay.  It is therefore possible that in this Coffer, made from an aerolite and therefore perhaps containing some element unknown in our world, may be imprisoned some mighty power which is to be released on its opening.”

This appeared to be an end of this branch of the subject; but as he still kept the fixed look of one who is engaged in a theme we all waited in silence.  After a pause he went on: 

“There is one thing which has up to now, I confess, puzzled me.  It may not be of prime importance; but in a matter like this, where all is unknown, we must take it that everything is important.  I cannot think that in a matter worked out with such extraordinary scrupulosity such a thing should be overlooked.  As you may see by the ground-plan of the tomb the sarcophagus stands near the north wall, with the Magic Coffer to the south of it.  The space covered by the former is left quite bare
