In the case of some of these binaries the parallax has been measured, from which it appears that in four of the surest cases the orbits are about the size of the orbit of Uranus, these being probably among the smallest stellar orbits. In 1834 and 1840 he began to suspect a want of uniformity in the proper motion of Sirius and Procyon respectively.
The logical and necessary explanation given of the cause of ordinary spectroscopic binaries, and of irregular proper motions of Sirius and Procyon, leads to the inference that if ever the plane of such a binary orbit were edge-on to us there ought to be an eclipse of the luminous partner whenever the non-luminous one is interposed between us.
Then Alpha faded to a dim bluish shimmer, Beta was eclipsed, Gamma was gone, Procyon dimmed to a failing spark; and suddenly Bart's memory accustomed itself to the load, the new habits were firmly in place, and he found himself eating, sleeping and working in a settled routine. He belonged to the Swiftwing now.
Kankad's people are building receiving sets to install on the Procyon and the Aldebaran, and another set for Kankad's Town. Pickering and his people are still working, but they all look pretty frustrated.
"Easy!" said a soothing voice. A Mentorian not the same Mentorian bent over him. "We have just entered the gravitational field of Procyon planet Alpha, Mr. Briscoe. Touchdown in four hours." Bart mumbled an apology. "Think nothing of it. Quite a number of people who aren't used to the cold-sleep drug suffer from minor lapses of memory. How do you feel now?"
There was a blast beside which the most terrific flash of lightning ever seen on Earth would have seemed like a firecracker. In what was almost a vacuum though she was, the whole immense mass of the Procyon was hurled upward like the cork out of a champagne bottle.
He was going to have to do some explaining to Steve later, but by that time it would be too late; the starship would be well on its way to Procyon. It was a dirty trick to play, he thought, but it was justifiable. In Hawkes' words, it was in a good cause.
"All passengers, will you pay attention, please?" All the high-fidelity speakers of the starship Procyon spoke as one, in the skillfully-modulated voice of the trained announcer. "This is the fourth and last cautionary announcement. Any who are not seated will seat themselves at once.
Although we have not devoted a great deal of time to coon hunting, one or another of our group has counted the scalps of quite a number of Procyon lotor. Having been accepted as a companion of one or two or more ambitious and enthusiastic dogs, we start out at dusk to hunt the creek bottoms for coons. Provided with bows, blunt arrows, and a lantern, we unleash the dogs, and the fun begins.
So, on the very first night on which the telescope could be used, I sat up until midnight to take a look at Procyon, not doubting that, with the greater power of our telescope, it would be seen at the first glance. To my great concern, nothing of the sort was visible.
