mountain god who held court there. Normally this temple was buried under the glacier, even the entrance being entirely sealed off by a massive wall of ice. But for some hitherto undiscovered reason, this front cliff of ice melts and breaks away once in about half a century, permitting entry to the temple. The Thibetans believe that the ice wall opens at the time that the gods of Thibet consider it propitious for a Grand Lama to assume the throne of the country, and that it has unfailingly opened (though there is no scientific evidence for this) for every incarnation of the Grand Lama – though the last three were prevented from visiting it at the prescribed time. Hence their tragically short lives, and the evil times in the country.
There is a definite limit to the period that the Ice Temple is accessible. About three to four weeks after the initial opening, the glacier begins to move once again and gradually seals the entrance to the Temple, keeping it sacrosanct until the time that another incarnation of the Grand Lama should be ready to sit on the Lion Throne of Thibet.
No convincing scientific explanation has ever been offered for this lusus naturae, though its existence has been reported by certain Russian explorers. My own view on the subject is, I believe, so far unique – if I may be pardoned the term – though I do not insist that it is necessarily the only correct one. The reader may take it as a mere theory; but a theory formulated by an intelligent and empirical observer.
Two distinct facts may be noted: 1. That the glacier is forced to travel in a deep gorge. 2. That the rock-face in front of the gorge – lining the ice wall – is formed of a very hard granitic rock, while the walls of the gorge itself are made up of a softer limestone. Thus, in time, the inner gorge has worn away much more than the mouth, creating a point of tremendous concentration and compression in front of the glacier.
My theory is that the enormous pressure exerted by the entire glacier on this small opening causes a marked decrease in the temperature in the ice at this point, and a subsequent hardening of its consistency (a natural phenomena that can be observed when snow is compressed to form snowballs). Thus an unusually hard and cold ice wall is formed at the front, effectively preventing the gradual melting and movement of the whole glacier, as normally occurs in all other glacial activities.
But though nature can be impeded, it can, of course, never be entirely halted. Year after year, the pressure builds up behind the ice wall, until eventually a point of surfeit is arrived at in the front, when the temperature cannot drop any more, or the ice harden. This slow build up of pressure may take up to fifty years, hence accounting for its coincidence with the coming of age of the Grand Lamas. Once this crucial stage is reached, the entire front of the narrow ice wall breaks open to reveal the entrance to the hidden temple. The sudden drop of pressure and temperature in front causes the whole phenomenon to start all over again, and slowly, in the space of many weeks, the entrance to the temple is once again covered by a solid wall of ice.
It was nearly dark on the second day when we camped at the foot of the pass that led over the mountains. High above us, up into the dark cloudy skies, soared the white jagged peaks of the long mountain chain. Beneath the snows, the slopes were grey with bare rocks and boulders, only an occasional wind-racked dwarf pine and solitary patches of tough gorse providing some relief to this grim scene.
The Grand Lama did not seem to become in any way affected by our hard journey nor the desolation of the surroundings. In fact he seemed to be enjoying himself thoroughly. He was, after all, a boy, and what boy if unnaturally confined for a lifetime to the company of dull teachers, old retainers and guards, would not enjoy the freedom of such an outing – rough though it may be. He ran around the campsite throwing stones at the bushes and joining Mr Holmes asked him innumerable questions about his life, about England and the world. It surprised me to observe Mr Holmes listening and replying patiently to the boy's many queries. But as I had occasion to notice before, underneath that hard, rational exterior and the assured egotism that often annoyed many, he had a remarkable gentleness and courtesy in his dealings with women and children.
Next day we made our way up through the high and forbidding mountains. Our trail was covered with rocks and patches of ice, while higher up it was all snow. Our sturdy ponies plodded on the whole morning, wending their way through the bleak maze of icy peaks, while we huddled on our saddles trying to protect ourselves from the fury of the elements. I tried to shield myself from the occasional sleet with my trusty umbrella, but it was blown inside-out the very first time by a blast of freezing wind, and only after a monumental tussle did I eventually manage to close it, and put it away.
Tsering and the soldiers, who all had long hair, now rearranged their tresses loosely before their eyes to prevent snow blindness. The rest of us had to make do with strips of coloured gauze. At about two o'clock in the afternoon we rode through a particularly windy vale between two massive peaks and, crossing it, finally got the first glimpse of our goal.
The mountains opened up in front of us into a field of glistening snow about a mile long, that abruptly ended in a wide chasm that cut right across it in the dramatic manner of the Grand Canyon in North America. A natural bridge of ice spanned this chasm and was seemingly the only way across it. On the other side the snow field continued – littered with great chunks of icy debris – and was gradually hemmed in between sheer cliffs of rock that fanned out from the high narrow front of the glacial wall. This wall of ice stood at least five hundred feet high and about a hundred feet wide, smooth and vertical, like a gigantic pane of glass. At the base of the wall was a dark regular opening which I realised was the entrance to the Ice Temple of Shambala. The ground in front of the wall was covered with thousands of pieces of broken ice, giving the impression of a stormy, wave-tossed sea that had become suddenly frozen.
Shivering on the backs of our ponies, we surveyed this awesome scene. I also took the precaution of examining the various details of the surrounding topography with my small telescope.
'Well, Mr Holmes,' said I cheerfully, removing the instrument from my eye, 'it seems that your insistence on speed has paid dividends. We have certainly arriyed here before Professor Moriarty and his Chinese chums. I can see no sign of any human presence around here.'
'But that is not as it should be,' said the Lama Yonten, worriedly.
'What do you mean, Sir?' asked Sherlock Holmes.
'Two monks, the 'Watchers of the Ice Temple ', live here, in a cave at the side of that ridge.' The Lama pointed to the mountain to our right. 'Besides their main task of reporting the opening of the temple entrance, it is one of their duties to prevent travellers from crossing that bridge and inadvertently profaning sacred ground. But where are they?'
'They may be in their cave. They may not have heard us coming.'
'That is not possible. The surrounding mountains funnel all sounds from the valley towards their cave. That is why it was chosen. They should have heard our arriving at least an hour ago, and come to receive us.'
'Humm. It would be well if we were cautious,' said Holmes grimly, his brows knitting with concern, 'Let me have that spyglass of yours for a minute, Hurree.'
'Certainly, Sir.'
He clapped the instrument to his eyes and made a systematic survey of the surroundings. The rest of us waited silently, A little chill of fear crept into me as I realised that I may have spoken too soon.
'The small wooden door to the 'Watchers' cave is open and swinging about in the wind,' said Holmes anxiously. 'On the opposite ridge aflightof snow pigeons is circling nervously above its nests. Wherever they are, they are well-hidden.'
'We have to go between those two ridges to get to the ice bridge,' said Tsering gravely. 'I think they may be waiting behind them.'
'When do you think they will attack?'
'Probably when we get near the ice bridge and descend from our ponies to walk across. That would be the most dangerous moment. We would be trapped like bugs between the claws of a scorpion.'
'Well, we shall see,' said Holmes calmly. Turning towards us he addressed us in a firm, measured tone. 'We will ride single file, with His Holiness and the Lama Yonten in the centre. Tsering and I will ride in front with five soldiers. Kintup and the other five soldiers will follow the Lamas. You, Hurree, will bring up the rear. On the first sign of an attack we will race straight to the bridge and ride across it. It may seem a foolhardy thing to do, but it is the only chance we have against a large enemy force. Over here the valley is too flat and bare. Once we cross the ice bridge you, Tsering, will position the soldiers behind those large blocks of ice and hold off all pursuers. It will not be too difficult since they will only be able to cross the bridge single file. The Lama Yonten and I will take His Holiness inside the temple. Now remember, don't hesitate at the bridge. Ride straight across it. They will not be expecting us to do that, and it may provide us the necessary element of surprise for the success of our plan. Good Luck.'
