My Terminal Moraine | Page 6

they labored steadfastly for ten days or more before Tom was ready to announce what it was he had hoped to discover, and whether or not he had found it. For a day or two I watched the workmen from time to time, but after that I kept away, preferring to await the result of my friend's operations. He evidently expected to find something worth having, and whether he was successful or not, it suited me better to know the truth all at once and not by degrees.
On the morning of the eleventh day Tom came into the room where I was reading and sat down near me. His face was pale, his eyes glittering. "Old friend," said he, and as he spoke I noticed that his voice was a little husky, although it was plain enough that his emotion was not occasioned by bad fortune--"my good old friend, I have found out what made the bottom of your gravel-pit so uncomfortably cold. You need not doubt what I am going to tell you, for my excavations have been complete and thorough enough to make me sure of what I say. Don't you remember that I told you that ages ago there was a vast glacier in the country which stretches from here to the mountains? Well, sir, the foot of that glacier must have reached further this way than is generally supposed. At any rate a portion of it did extend in this direction as far as this bit of the world which is now yours. This end or spur of the glacier, nearly a quarter of a mile in width, I should say, and pushing before it a portion of the terminal moraine on which you live, came slowly toward the valley until suddenly it detached itself from the main glacier and disappeared from sight. That is to say, my boy"--and as he spoke Tom sprang to his feet, too excited to sit any longer--"it descended to the bowels of the earth, at least for a considerable distance in that direction, Now you want to know how this happened. Well, I'll tell you. In this part of the country there are scattered about here and there great caves. Geologists know one or two of them, and it is certain that there are others undiscovered. Well, sir, your glacier spur discovered one of them, and when it had lain over the top of it for an age or two, and had grown bigger and bigger, and heavier and heavier, it at last burst through the rock roof of the cave, snapping itself from the rest of the glacier and falling in one vast mass to the bottom of the subterranean abyss. Walter, it is there now. The rest of the glacier came steadily down; the moraines were forced before it; they covered up this glacier spur, this broken fragment, and by the time the climate changed and the average of temperature rose above that of the glacial period, this vast sunken mass of ice was packed away below the surface of the earth, out of the reach of the action of friction, or heat, or moisture, or anything else which might destroy it. And through all the long procession of centuries that broken end of the glacier has been lying in your terminal moraine. It is there now. It is yours, Walter Cuthbert. It is an ice-mine. It is wealth, and so far as I can make out, it is nearly all upon your land. To you is the possession, but to me is the glory of the discovery. A bit of the glacial period kept in a cave for us! It is too wonderful to believe! Walter, have you any brandy?"
It may well be supposed that by this time I was thoroughly awakened to the importance and the amazing character of my friend's discovery, and I hurried with him to the scene of operations. There he explained everything and showed me how, by digging away a portion of the face of the bluff, he had found that this vast fragment of the glacier, which had been so miraculously preserved, ended in an irregularly perpendicular wall, which extended downward he knew not how far, and the edge of it on its upper side had been touched by my workmen in digging their pit. "It was the gradual melting of the upper end of this glacier," said Tom, "probably more elevated than the lower end, that made your dell. I wondered why the depression did not extend further up toward the spot where the foot of the glacier was supposed to have been. This end of the fragment, being sunk in deeper and afterward covered up more completely, probably never melted at all."
"It is amazing--astounding," said I; "but what of
