AT eight o'clock the next morning,a faint kind of dawn of day awoke us.The thousand and one prisms of the lava collected the light as it passed and brought it to us like a shower of sparks.
We were able with ease to see objects around us.
"Well,Harry,my boy,"cried the delighted Professor,rubbing his hands together,"what say you now?Did you ever pass a more tranquil night in our house in the Konigstrasse?No deafening sounds of cart wheels,no cries of hawkers,no bad language from boatmen or watermen!
"Well,Uncle,we are quite at the bottom of this well-but to me there is something terrible in this calm.""Why,"said the Professor hotly,"one would say you were already beginning to be afraid.How will you get on presently?Do you know,that as yet,we have not penetrated one inch into the bowels of the earth.""What can you mean,sir?"was my bewildered and astonished reply.
"I mean to say that we have only just reached the soil of the island itself.This long vertical tube,which ends at the bottom of the crater of Sneffels,ceases here just about on a level with the sea.""Are you sure,sir?"
"Quite sure.Consult the barometer."
It was quite true that the mercury,after rising gradually in the instrument,as long as our descent was taking place,had stopped precisely at twenty-nine degrees.
"You perceive,"said the Professor,"we have as yet only to endure the pressure of air.I am curious to replace the barometer by the manometer."The barometer,in fact,was about to become useless-as soon as the weight of the air was greater than what was calculated as above the level of the ocean.
"But,"said I,"is it not very much to be feared that this ever-increasing pressure may not in the end turn out very painful and inconvenient?""No,"said he."We shall descend very slowly,and our lungs will be gradually accustomed to breathe compressed air.It is well known that aeronauts have gone so high as to be nearly without air at all-why,then,should we not accustom ourselves to breathe when we have,say,a little too much of it?For myself,I am certain I shall prefer it.Let us not lose a moment.Where is the packet which preceded us in our descent?"I smilingly pointed it out to my uncle.Hans had not seen it,and believed it caught somewhere above us:"Huppe"as he phrased it.
"Now,"said my uncle,"let us breakfast,and break fast like people who have a long day's work before them."Biscuit and dried meat,washed down by some mouthfuls of water flavored with Schiedam,was the material of our luxurious meal.
As soon as it was finished,my uncle took from his pocket a notebook destined to be filled by memoranda of our travels.He had already placed his instruments in order,and this is what he wrote:
Monday,June 29th Chronometer,8h.17m.morning.
Barometer,29.6inches.
Thermometer,6degrees [43degrees Fahr.]
Direction,E.S.E.
This last observation referred to the obscure gallery,and was indicated to us by the compass.
"Now,Harry,"cried the Professor,in an enthusiastic tone of voice,"we are truly about to take our first step into the Interior of the Earth;never before visited by man since the first creation of the world.You may consider,therefore,that at this precise moment our travels really commence."As my uncle made this remark,he took in one hand the Ruhmkorff coil apparatus,which hung round his neck,and with the other he put the electric current into communication with the worm of the lantern.
And a bright light at once illumined that dark and gloomy tunnel!
The effect was magical!
Hans,who carried the second apparatus,had it also put into operation.This ingenious application of electricity to practical purposes enabled us to move along by the light of an artificial day,amid even the flow of the most inflammable and combustible gases.
"Forward!"cried my uncle.Each took up his burden.Hans went first,my uncle followed,and I going third,we entered the somber gallery!
Just as we were about to engulf ourselves in this dismal passage,I lifted up my head,and through the tubelike shaft saw that Iceland sky I was never to see again!
Was it the last I should ever see of any sky?
The stream of lava flowing from the bowels of the earth in 1219had forced itself a passage through the tunnel.It lined the whole of the inside with its thick and brilliant coating.The electric light added very greatly to the brilliancy of the effect.
The great difficulty of our journey now began.How were we to prevent ourselves from slipping down the steeply inclined plane?
Happily some cracks,abrasures of the soil,and other irregularities,served the place of steps;and we descended slowly;allowing our heavy luggage to slip on before,at the end of a long cord.
