Saturday the Twenty-Ninth
Once more I’m a grass widow. My Duncan is awa’. He scooted for Calgary as soon as his threshing-work was finished up. But that tumult is over and once more I’ve a chance to sit down and commune with my soul. Everything here is over-running with wheat. Our bins are bursting. The lord of the realm is secretly delighted, but he has said little about it. He has a narrow course to steer. He is grateful for the money that this wheat will bring in to him, yet he can see it would never do to harp too loudly on the productiveness of our land—on my land, I ought to say, for Casa Grande has now been formally deeded to me. I find no sense of triumph, however, in that transfer. I am depressed, in fact, at the very thought of it. It seems to carry a vague air of the valedictory. But I refuse to be intimidated by the future.
Gershom and I, indeed, have been indulging in the study of astronomy. The air was crystal clear last night, so that solemn youth suggested that we take 164 out the old telescope and study the stars. Which we did. And which was much more wonderful than I had imagined. But Gershom had no reflector, so after getting a neck-ache trying to inspect the heavens while on our feet we took the old buffalo-robe and a couple of rugs out to a straw-pile that had been hauled in to protect our winter perennials. There we indecorously reposed on our backs and went stargazing in comfort. And Gershom even forgot that painful bashfulness of his when he fell to talking about the planets. He slipped out of his shell and spoke with genuine feeling.
He suggested that we begin with the Big Dipper, which I could locate easily enough well up in the northern sky. That, Gershom told me, was sometimes called the Great Bear, though it was only a part of the real Ursa Major of the astronomers. Then he showed me Benetnasch at the end of the Dipper’s handle, and Mizar at the bend in the handle, then Alioth, and then Megrez, which joins the handle to the bowl. Then he showed me Phaed and Merak, which mark the bottom of the bowl, and then Dubhe at the bowl’s outer rim.
I tried hard, but I was very stupid about getting the names right. Then Gershom asked me to look 165 up at Mizar, and see if I could make out a small star quite close to it. I did so, without much trouble, and Gershom thereupon condescended to admit that I had exceptionally good eyes. For that star, he explained, was Alcor, and Alcor was Arabic for “the proof,” and for centuries and centuries the ability to see that star had been accepted as the proof of good vision.
Then Gershom went on to the other constellations, and talked of suns of the first and second magnitude, and pointed out Sirius, in whose honor great temples had once been built in Egypt, and Arcturus, the same old Arcturus that a Hebrew poet by the name of Job had sung about, and Vega and Capella and Rigel, which he said sent out eight thousand times more light than our sun, and is at least thirty-four thousand times as big.
But it only made me dizzy and staggered my mind. I couldn’t comprehend the distances he was talking about. I just couldn’t make it, any more than a bronco that had been used to jumping a six-barred gate could vault over a windmill tower. And I had to tell Gershom that it didn’t do a bit of good informing me that Sirius was comparatively close to us, as it stood only nine light-years away. I remembered how 166 he had explained that light travels one hundred and eighty-six thousand miles a second, and that there are thirty million seconds in a year, so that a light-year is about five and a half million million of miles. But when he started to tell me that some of the so-called photographic stars are thirty-two thousand light-years away from us my imagination just curled up and died. It didn’t mean anything to me. It couldn’t. I tried in vain to project my puny little soul through all that space. At first it was rather bewildering. Then it grew into something touched with grandeur. Then it took on an aspect of awfulness. And from that it grew into a sort of ghastliness, until the machinery of the mind choked and balked and stopped working altogether, like an overloaded motor. I had to reach out in the cold air and catch hold of Gershom’s arm. I felt a hunger to cling to something warm and human.
“We call this world of ours a pretty big world,” Gershom was saying. “But look at Betelgeuse up there, which Michelson has been able to measure. He has, at least, succeeded in measuring the angle at the eye that Betelgeuse subtends, so that after estimating its parallax as given by a heliometer, it’s merely a matter of trigonometry to work out the size of the 167 star. And he estimated Betelgeuse to be two hundred and sixty million miles in diameter. That means it would take twenty-seven million of our suns to equal it in bulk. So that this big world of ours, which takes so many weeks to crawl about on the fastest ships and the fastest trains, is really a mote of dust, something smaller than the smallest pin-prick, compared to that far-away sun up there on the shoulder of Orion!”
