"But would not our chances of escape be considerably better," asked Count Timascheff, "in the event of either of the comet's poles being the point of contact?" "Taking the combined velocity into account," answered the lieutenant, "I confess that I fear the violence of the shock will be too great to permit our destruction to be averted."
A splendid photograph of 1,421 stars in the Pleiades, taken by the MM. Henry with three hours' exposure, November 16, 1885, showed one of the brightest of them to have a small spiral nebula, somewhat resembling a strongly-curved comet's tail, attached to it.
We might keep on our course and come to no harm, merely pawing through a gaseous mass which makes up the comet's tail. But there is a danger that we might strike the solid head of it, for that the head is solid, and of a glowing, fiery mass, which gives off a train of sparks, is my belief. To collide with a fiery ball, larger than the sun, would indeed be terrible.
Having expressed his desire for a search, all the observations of Fabricius and of Heller, and also a map of the comet's path among the stars, were eventually unearthed in the most unlikely manner, after being lost nearly three hundred years. Hind and others were certain that this comet would return between 1844 and 1848, but it never appeared.
I'll have you to know, sister Penelope, that my grandmother my own grandmother and Robert's own grandmother, not yours could remember the famous comet of seventeen hundred and forty-four, and that had six tails." Miss Penelope was daunted and silenced for the moment. She did not mind the greater number of the rival comet's tails. It was not that which made her feel herself at a disadvantage.
Then followed the reaction period of extreme cold, snow and ice the glacial period. This particular rock, while following in the train of its parent comet, though lagging many thousands of miles behind, still, being so very large, moved with accelerated speed towards the comet's head, passing on its way countless millions of smaller particles, whose cutting edges scored these grooves.
"Before the shock, sir," answered the professor, "I had conclusively demonstrated the path of the comet; but, in consequence of the modifications which that shock has entailed upon my comet's orbit, I have been compelled entirely to recommence my calculations." The lieutenant looked disappointed.
Flames that were colder by many hundred times, would make the dull black iron shine with incandescent brightness. As, however, it is the comet's nature to guard its ornamental appendages with jealous care, it may be conceived that this tail of 170 million miles might prove a somewhat troublesome travelling companion in so rapid a journey.
And lo! that very night there was an end of the Comet's splendor. "Adieu, my dull friends," said he; "I am tired of a quiet life: a little more, and I should fade out entirely!" Then, with a blaze and a whiz, and a dizzy wheel, he flashed out of the sky; and no one knew whither he went, or whence he came, any more than the path of the quick lightning.
According to Tait's sea-bird theory, the earth was at both these epochs in the plane of a sheet of meteorites forming the tail; but on each occasion the sun also was in the same plane, for the edge of the sheet of meteorites was seen to be directly in a line with the sun. The comet's head, of course, was in the same plane; but three points, not in a straight line, determine a plane.
