Garth stopped. Everything stopped as the acceleration began. Both of them were over-braced for the acceleration was light and even. It was only 5000 KM to the nearest warp-line. As acceleration slacked off for the five-minute coast into the warp, Garth lit another cigar and began.
Yet I imagined I was advancing nicely, so much so that I began to fear I had gone beyond my destination. About four o'clock in the afternoon I struck a small river and followed its crooked course to the coast, so as to get my bearings. Great was my disappointment on finding myself only about 1 1/2 km. from the lagoon which I had left in the morning.
The whole black hulk was turning in space, a hundred KM away, lining up its armament. It would only be seconds. Thane looked at the Third. He seemed to be confused, and was fumbling almost blindly with the instruments. He twisted dials almost at random, on the edge of panic. Thane hesitated then realized what it must be Stoltz artillery.
'Q' is the end of the phrase "I thank you" 'Km' is the end of the phrase "You are welcome." Mr. Little puts no emphasis upon either of them, but delivers them so reduced that they hardly have a sound.
Now it appears that AK and BL dip down toward the side where the air is less easy to penetrate: for AK being longer than BL, and parallel to it, it follows that the lines AB and KL, being prolonged, would meet at the side L. But the angle K is a right angle: hence KAB is necessarily acute, and consequently less than DAB. If one investigates in the same way the progression of the portion of the wave KL, one will find that after a further time it has arrived at MN in such a manner that the perpendiculars KM, LN, dip down even more than do AK, BL. And this suffices to show that the ray will continue along the curved line which intersects all the waves at right angles, as has been said.
For anyone who may be interested very comprehensive reports of the work done in transequatorial propagation during cycle 21 and earlier appeared in articles written by Ray Cracknell ZE2JV/G2AHU and Roland Whiting 5B4WR/G3UYO in the June/July/August 1980 issues of Radio Communuication, the journal of the R.S.G.B. and in the November/December 1980 issues of QST.

If one considers further the other pieces H of the wave AC, it appears that they will not only have reached the surface AB by straight lines HK parallel to CB, but that in addition they will have generated in the transparent air, from the centres K, K, K, particular spherical waves, represented here by circumferences the semi-diameters of which are equal to KM, that is to say to the continuations of HK as far as the line BG parallel to AC. But all these circumferences have as a common tangent the straight line BN, namely the same which is drawn from B as a tangent to the first of the circles, of which A is the centre, and AN the semi-diameter equal to BC, as is easy to see.
