But the interests of Kiruna are not altogether centered in the far horizon. At half-past eight in the morning, and again at half-past four in the afternoon, I was startled by a series of tremendous explosions. They could not be thunderclaps, for there were few clouds in the sky and not the slightest indication of a storm.

Over and over again the thundering volleys rolled, and as I looked toward the west I could see a vivid flash in the darkness preceding the thunderclap by some seconds. And yet the flash and the thunder did not seem to come from the sky, but from a massive hill, which bulked dimly against the horizon, across an intervening valley. You have already guessed what the bombardment was. It came from the mighty iron mountain of Kiruna and was the explosion of the dynamite charges which every morning and every afternoon are set off to loosen the ore. More like a rapid-fire Gatling gun perhaps than like thunderclaps the explosions became, after the first few shots, and from various parts of the mountain, high up and low down, and to the right and the left, one could see the dull flashes and hear the reverberating roar, scores of shots every minute, until perhaps two hundred had been fired.

This iron mountain accounts for a lot of things in this part of the world. This was the magnet which drew the railway, the most northerly railway on the face of the earth, up so far through the dreary Lapland wilds. Do not suppose for a moment that the Swedes were so philanthropic as to build the road for the sake of a few Americans who wanted to see the Midday Moon or the Midnight Sun (for you must know that you can see his Majesty from the top of Kiruna’s iron mountain all day long if you happen to be there any day during the latter part of June). No, it was this great loadstone mountain that compelled the thrifty Swedes to build a railway through the snow a thousand miles north of Stockholm. Their enterprise was well repaid, for this mountain is from fifty to sixty per cent solid iron, and the best iron in the world.

From Kiruna it is transported nearly one hundred miles farther north to Narvik, across the Norwegian border, where there is an ice-free port all the year round, and where great ships are constantly waiting within its quiet fjord to transport sections of Kiruna’s iron mountain to New York and Philadelphia and London and Hamburg and Boston. There is another iron hill some five or six miles from Kiruna, from which the ore is shipped by overhead electric skids to Kiruna and thence transported by rail to Narvik. Indeed it is said by geologists that all the hills about this little Arctic metropolis are full of iron, and they are not likely to be exhausted for a thousand years to come.

Kiruna reminds me of a hustling American town more than any other that I have seen in this part of the world. It is only fourteen years old, and yet it has ten thousand inhabitants; hundreds of well-built houses; a good electric tramway, which carries the miners back and forth from the works on the mountain to their homes in the little city; four fine schoolhouses, and a big church with a huge bell tower, situated at some little distance from the sanctuary.

Let us not plume ourselves on the thought that we have all the enterprise in the world, or lay the flattering unction to our souls that no one else can build a city in a decade, for here is one with all the conveniences and comforts and many of the luxuries of life; and if we go another hundred miles farther north we shall find a still larger town, less than twelve years old, with good blocks of stores, large residences, and splendid wharves, to which the commerce of the world pays tribute; for Narvik, where the sun does not rise for a month or six weeks in wintertime, is even younger than Kiruna. To-morrow I intend to go to Luleå (pronounce it Luleo, for the little circle over the a gives it the o sound), and I will finish this arctic letter there.

Luleå on the Baltic.

A funny, if chilly, experience awaited me when I arrived here last night. It was well on toward midnight, and, though a crowd of fellow passengers disembarked from the third-class cars, there was no hotel porter or trager or dienstman to tell me where I should go. My somewhat aged Baedeker had not informed me of the name of a single hotel.

The only individual who took any interest in me was a small boy, and from his voluble Swedish and more comprehensible gestures I felt that he wished to lead me to a hotel. Having nothing better to do, I followed my diminutive guide. It was very cold, at least twenty degrees below zero, the severest weather I have seen at all in this northland. The streets were dark, for most of the electric lights had been put out, but I followed the small boy trustingly. When I seemed to waver in my allegiance, he would run back and urge me on. At last we came to a house which had few signs of being a hostelry. I suspect it was his mother’s humble residence. I followed him in at the door, and he discoursed fluently to the lady of the house, apparently telling her of my needs. She looked quite as blank as I did, but at last she opened a door into a somewhat shabby parlor and gave me to understand that I could sleep on the lounge if I wished to.
