At this point a series of undulations that have been apparent as a perplexing complication as far back as Cavor’s description of the silence that fell before the first speaking of the Grand Lunar become confusingly predominant in the record. These undulations are evidently the result of radiations proceeding from a lunar source, and their persistent approximation to the alternating signals of Cavor is curiously suggestive of some operator deliberately seeking to mix them in with his message and render it illegible. At first they are small and regular, so that with a little care and the loss of very few words we have been able to disentangle Cavor’s message; then they become broad and larger, then suddenly they are irregular, with an irregularity that gives the effect at last of someone scribbling through a line of writing.
