M'Allister had intended going on to Glasgow during the previous week, but had remained at home at Norbury to a.s.sist in securing my release; doing yeoman's service in seeing various people and carrying messages.

When things had quite settled down again he went to Scotland and stayed with his wife for three weeks.

Upon his return we discussed our future arrangements, and agreed to become partners for the purpose of securing and working patents for various machines which we had studied upon Mars; and this has proved a lucrative business for us, besides supplying our engineers and manufacturers with greatly improved machinery.

Ever since our return home we have eagerly read all the scientific news concerning Mars that has been published, for we were anxious to learn whether there had been any verification of the Professor's forecasts as to what was likely to be seen from the earth at the opposition of Mars in 1909. The result is very gratifying to us, not only as proving the correctness of the Professor's p.r.o.nouncements, but also as testifying to the keen-sightedness of some of our astronomers and their carefulness and accuracy as observers; though, of course, there are still divergences of opinion as to the meaning of what has been seen.

MARS, AS SEEN THROUGH A 12-INCH TELESCOPE ON 16TH AUGUST, 1909

The south polar snow-cap is seen at the top, and as it is early June on this part of Mars, the snow-cap has become small. The dark line across it is a wide rift, the ice having commenced to break up at this part; and the dark shading round it is water from the melting snow. The circular light area near the centre is "h.e.l.las," and the dark wedge-shaped area is "Syrtis Major." The protuberance usually seen on the eastern side of Syrtis Major has this year almost disappeared, and but little detail is visible anywhere.]

For instance, M. Antoniadi, of Juvisy Observatory, near Paris, has published a very interesting account of his own observations with the fine Meudon refractor, which has an object gla.s.s 32.7 inches in diameter; and he has also furnished several beautifully executed drawings of what he has seen. The most noticeable new features observed were two large detached pieces of the south polar snow-cap, the altered shape of the Solis Lacus and other dark areas, numerous dark rounded spots on the dark areas, much detail along the lines of the ca.n.a.ls, and the observation of scattered markings instead of lines.

M. Antoniadi lays great stress on the advantages of large telescopes; and, whilst making frank admission that the drawings of Professor Lowell show the outlines of the Martian details more accurately than the drawings of any other observer, he dissents entirely from his views respecting the actuality of the ca.n.a.l lines.

With regard to M. Antoniadi's observation of dark rounded spots, it has been suggested by another writer that these are volcanoes, and, moreover, that the ca.n.a.l lines are really cracks in the solid ice covering frozen oceans and seas. These contentions involve the supposition that Mars is still in the stage when volcanic action is prevalent, and also that what have hitherto been supposed to be desert lands are really fields of ice. Mars has pa.s.sed far beyond the stage of volcanic activity; and the theory does not account for the ochre colour of the frozen oceans, which are exactly the same colour as our deserts appear when viewed from a great distance, for the sandstorms so frequently observed, nor for the general absence of any indications of frost over a large portion of the Martian surface. It is also very difficult to imagine the existence of a profuse growth of vegetation along cracks in solid ice; and I am afraid this theory, like many others, fails to fit in with the observed facts.

I may remind my readers that the Professor suggested that many more dark rounded spots would, under favourable conditions, be discovered on the dark areas of the planet, and he has stated what they are.

As a result of his recent observations, M. Antoniadi has boldly declared that the supposed ca.n.a.l lines are really separate spots and markings which, when seen with instruments of lesser power than the one he used, appear to be lines, the network of ca.n.a.l lines being an illusion. He contends that the markings he has seen are beyond the power of Professor Lowell's telescope to resolve, and that what he has seen forms an unanswerable objection to the ca.n.a.l theory and stops all discussion!

This argument has, however, been fully met in this book by antic.i.p.ation; and, as will be seen later on, Professor Lowell completely refutes it and shows that M. Antoniadi is mistaken. It has also been pointed out that, if we could secure perfect seeing, the lines might really appear as separate markings, and that apparent breaks and irregularities are exactly what we might expect to find in connection with ca.n.a.ls. I gather from a recent remark made by Professor Lowell that he also holds this view.

Moreover, a discreet silence is observed with regard to the progress of vegetation on Mars being from the poles towards the equator, instead of from the equator towards the poles, as is the case on our earth.

This mode of progression can only be accounted for by the flow of water from the poles, and such flow extending beyond the equator involves the artificial propulsion of the water, as the flow is contrary to gravitation.

Professor Lowell's statements as to this peculiar growth of the vegetation do not depend upon the results of a few casual observations, for he has given the matter most systematic and prolonged attention, and noted upon hundreds of charts the dates when the vegetation has first appeared in various places and lat.i.tudes after the pa.s.sage of the water down the ca.n.a.ls.

This is such a hard nut for the opponents of the ca.n.a.l theory to crack, that I am quite prepared to learn that all these careful observations are merely illusions.

Professor Hale, of Mount Wilson Observatory, in California, has taken some photographs of Mars which do not show any ca.n.a.l lines; and these have been eagerly seized upon as another proof that the ca.n.a.ls have no existence.

Unfortunately, these photographs do not show many well authenticated details which are seen with comparative ease, nor the new details seen by M. Antoniadi. It is, therefore, no matter of wonder that they do not show the much fainter ca.n.a.l lines. If the absence of the ca.n.a.l lines from the photographs is proof that the ca.n.a.ls do not exist, then the photographs must still more emphatically prove that these much more conspicuous details--which have been seen and drawn by M. Antoniadi and scores of other observers--are also illusions and have no objective existence. Those who seek the support of these photographs for their views must be left to extricate themselves as best they can from the dilemma in which they are now placed in regard to the observations and drawings of those highly skilled observers.

The photographs were taken with a sixty-inch telescope, and possibly this very large aperture was not stopped down sufficiently to secure on the photographic plates such very fine detail as the ca.n.a.l lines; on the other hand, the atmospheric conditions at the moments of exposure of the plates may have been unfavourable for good definition. However good the photographs may be, the deductions drawn from them are erroneous.

Against such purely negative evidence--which never affords good ground for argument--we must set the positive evidence of Professor Lowell's numerous photographs, which do show many of the ca.n.a.l lines and also confirm the drawings of observers.

Professor Schiaparelli, who has been appealed to on the subject, still maintains the objectivity of the ca.n.a.l lines which he was the first to discover, and repudiates the suggestion that the new photographs supply any evidence against them. He remarks that during the last thirty years many other astronomers, using more perfect telescopes than his, have observed and drawn these ca.n.a.l lines, and have taken photographs which reproduce an identical disposition of the lines. He adds that a collective illusion on the part of so many astronomers is impossible, and that the photographs which do show the ca.n.a.ls cannot be illusions.

Professor Lowell controverts M. Antoniadi's claim to have proved that the lines are non-existent, and that the only markings are small separate shadings which are illusively seen as lines. He points out that what M. Antoniadi has seen is exactly what would be seen when using a very large telescope, and that it indicates poor seeing instead of good definition. He remarks that when using such large instruments, which are so much more affected by atmospheric conditions than smaller ones, the diffraction rings round a star (which should appear as complete concentric circles) begin to waver, then break up into fragments--a sort of mosaic--and finally end in an indiscriminate a.s.semblance of points.

In certain kinds of bad seeing the parts may seem quite steady, but the fact that the mosaic exists is proof positive of poor seeing. What happens to the rings in such circ.u.mstances must also happen to fine lines! the mosaic effect seen by M. Antoniadi is therefore "the exact theoretic effect that a large aperture should produce on continuous lines, such as the ca.n.a.ls, and always does produce in the case of the rings in the image of a star!"

It has been stated that Professor Lowell had admitted the illusory nature of the ca.n.a.l lines. His reply, however, is emphatic: "I have never made any retractation as to the reality and geometricism of the ca.n.a.ls; they are marvellous beyond conception, and are only doubted by those who never observed the planet itself sufficiently well."

Seeing an announcement that Professor Lowell had arrived in England for the purpose of lecturing on "Planetary Photography" at the Royal Inst.i.tution of Great Britain, M'Allister and I made up our minds to be present at the lecture, a resolution which, I am glad to say, we carried into effect.

In the course of his lecture Professor Lowell gave an account of the methods of planetary photography initiated and carried on with such success at the Lowell Observatory; and then proceeded to give some interesting particulars of his observations of Mars at the opposition of 1909, which resulted in one of the most important discoveries ever recorded in connection with that planet.

He stated that on the 30th September, 1909, when the region of the desert to the east of Syrtis Major came into view, after its periodic six weeks' invisibility due to the unequal length of the days of the earth and Mars, some long new ca.n.a.ls were plainly observed which had not been visible when the region was previously in view. A long and careful investigation of fifteen years' records proved absolutely that not only had these ca.n.a.ls never been seen before, but that they could not have existed. They are on a region which is frequently very favourably situated for observation, and could not possibly have been overlooked, for they are now the most conspicuous objects on that part of the planet. It is beyond question that they are not only new to us but new to Mars!

The two main ca.n.a.ls run in a south-easterly direction from Syrtis Major, and with them are a.s.sociated two smaller ones and at least two new oases; while, from their inter-connection, they are all clearly parts of one and the same addition to the general ca.n.a.l system; for they now fit in with the system as though they had always formed part of it. These new ca.n.a.ls were not only seen and drawn, but several photographs were taken at different times.

Consider what this great discovery really means! In a region which has never been anything but a desert during the whole period over which our observational knowledge of Mars has extended, there are now strips of land many hundreds of miles in length and miles wide that have become fertile almost under our very eyes; and this result has been brought about by the pa.s.sage through them of water which has artificially been carried there for the purpose of irrigation! We know this is so, for what we see is the growth of vegetation; and the systematic way in which the new ca.n.a.ls have been fitted into the existing ca.n.a.l scheme proves the artificiality of the whole system.

Some sensational statements in the Press have fostered in many minds the idea that all these hundreds of miles of new ca.n.a.ls were constructed within the very short period of six weeks! This is altogether wrong. It is the _vegetation_ that has _grown_ in six weeks, in consequence of the turning on of the water to the irrigation works. We have good scientific reasons for believing that irrigation works on Mars could be accomplished much quicker than on the earth; but, as the telescope does not enable us to see the works, we do not know how long they may have taken to construct. It may have been months, or years. We only see the _results_ of the works when actually in operation.

When we consider these works and their results, surely it becomes impossible to resist the evidence of intelligent design which they furnish; while if we also remember the very recent development of these ca.n.a.ls, the existence of life upon Mars at the present time seems to be demonstrated beyond the possibility of reasonable doubt! In what physical form that life is enshrined even our science must fail to reveal. Professor Lowell, however, pointed out that the inhabitants of Mars are not necessarily human beings, but their work clearly proves that they are beings endowed with a very high degree of intelligence. A study of the ca.n.a.l system reveals a marvellous conception marvellously carried into effect.

Observers at Flagstaff have, therefore, practically seen the completion of a work which is the creation of intelligent beings on Mars; and in the remarkable photographs shown we were, so to speak, able to look upon the results of that work--fertility in a region which had previously been an arid desert.

The water, as the lecturer remarked, was probably not in all cases conveyed by means of ca.n.a.ls dug out of the soil, but we know that in some way--whether by ca.n.a.ls, or by trunk lines of pipes and smaller subsidiary pipes, or otherwise--the land has been artificially irrigated and fertilised by water, which could not possibly have taken the course it has without being intelligently directed. Tunnelling would be easy on Mars.

Professor Lowell spoke of these matters in well-weighed and well-chosen phrases, which carried conviction of his earnestness and sincerity to the minds of his hearers; and we observed that the audience was evidently profoundly impressed by the importance of his statements. This fact seemed to us very significant, as he was addressing one of the most brilliant a.s.semblies--representing many branches of science--ever gathered within the walls of the Royal Inst.i.tution. The numerous photographs showing the Martian ca.n.a.l lines were projected on to the screen by a lantern, and thus their convincing evidence was clearly brought before the whole of that vast audience.

Another very interesting series of photographs showed the coming and going of the first frost of the season in the antarctic regions of Mars.

This frost was first observed and photographed at Flagstaff on the 16th November, 1909, and other photographs were taken on the 22nd of that month.

In connection with these, Professor Lowell quaintly remarked that, "To chronicle thus the very weather on our neighbour will convince any one that interplanetary communication has already commenced; and that, too, after the usual conventional manner by mundane greetings."

Referring to the photographs, it was pointed out that the human eye can see at least ten times as much as a photograph can show as regards planetary detail. This, though not generally known, is perfectly true, and it may be explained thus: We know that in terrestrial photography the camera will reveal many details which the eye is apt to overlook; and, by very long exposures, even celestial photography will give a similar result. In _planetary_ photography, however, exposures must be very short, and the picture obtained is so very tiny that it cannot show all that the eye could see. Under good conditions, therefore, the eye at the telescope will always see immensely more of the finer details on a planet than any camera could show.

The great value of the photographs of Mars lies in the fact that they demonstrate beyond the possibility of doubt the existence of certain fine markings which many observers have seen and drawn, but as to the reality of which others, less skilled or less favourably situated, have been extremely sceptical. If the fine lines had no existence on the planet they could not be photographed.

In drawing attention to the details on these photographs Professor Lowell emphatically declared that, "The lines you see are '_certainties_,' not matters admitting of the slightest question, for all their strange regularity. Not only I, but all my a.s.sistants, have seen them thousands of times the same, and sometimes with all the clearness and sharpness of etchings or steel engravings.

"An optical mistake," he then remarked, "which has latterly been hailed as showing that the lines were not lines but a series of dots, was made the other day in France. The observer saw perfectly correctly, but one with knowledge of the optics of a telescope should have known that the effect observed was the inevitable result of using an aperture which the seeing did not warrant; as he could easily have a.s.sured himself by looking at the shattered rings round the synchronous image of a star."

It may here be pointed out that these weighty and well-considered declarations--which are a complete answer to M. Antoniadi's bold claim--were made by the most experienced observer of Mars, who, as even his opponents admit, possesses the finest site in the world for his astronomical work, and is equipped with a very perfect instrument.

Besides the splendid photographs of Mars, many views of Jupiter and Saturn were shown, exhibiting clearly numerous fine details, markings, and wisps as to which much doubt had been expressed when some observers had shown them on their drawings. These beautiful and convincing results of the clever and original methods of planetary photography adopted at Flagstaff appeared to come as a complete revelation to the majority of those present, notwithstanding their scientific experience.

Probably never before had anything so wonderful as these results of skill, patience, and prolonged research been exhibited, even in that great and historic home of science. As Professor Lowell remarked in a fine peroration: "They exhibited something of the advance recently achieved in our knowledge of solar science; on the other hand, they const.i.tuted in themselves the beginning of a set of records in which the future of the planet might be confronted with its achieved past, and which should endure after those who first conceived such registry had long pa.s.sed away.... They were histories of the planets written by themselves--their autobiographies penned by light; and in their grand historical portrait-gallery astronomers yet to come might see the earlier stages of the great cosmic drama which was slowly but surely working itself out!"

At the conclusion of this most interesting lecture M'Allister turned to me and said, "How I wish our old friend the Professor could have been here to-night; he would have keenly appreciated what we have heard."

"Yes, he would indeed," I answered; "but remember, he knows more now than any one we see here could tell him about Martian matters!"

Before concluding, it may be of interest to state that Professor Lowell still maintains the accuracy of the discovery made at Flagstaff that the existence of water vapour on Mars is demonstrated by the photographic spectrum of the Martian atmosphere; and he a.s.serts that the attempt to disprove it has failed. A further discovery has since been made at the same observatory, viz. that oxygen also is present in the atmosphere of Mars!

During the observations in 1909 several observers noted that, at times, very large areas on the surface of Mars had been so obscured by a yellowish veiling that all details were entirely blotted out. The announcement of this fact gave rise to sensational statements that a terrible catastrophe had occurred on the planet. The explanation is, however, very simple--seasonal mists arising from the ca.n.a.ls, with the addition of clouds of sand particles in the upper air, as the result of desert sandstorms, caused a temporary obscuration of certain parts of the planet as viewed from the earth. Only this, and nothing more!

We have been interested to note that an English observer, the Rev.

Theodore E.R. Phillips, has observed some new details on Mars in the region where the new ca.n.a.ls were discovered. Mr. Phillips has in past years given considerable attention to this region, and observed several changes in the Lacus Moeris, to the east of Syrtis Major. The lake disappeared altogether for some considerable time, then reappeared. Last September he saw it again, and it was evident some further changes had occurred; and he also saw some dusky shadings on the adjacent desert of Lybia. There seems little doubt but that he actually saw, though imperfectly, the new ca.n.a.ls which Professor Lowell's much clearer atmosphere and larger instrument enabled him to see clearly.

From what has been related in the last few pages it will be seen that many of the forecasts, as set forth in this book by our old friend the Professor, and his statements as to the Martians being actively engaged in altering, extending, and developing their ca.n.a.l system, have been amply verified by the observations of our astronomers; and I am confident that his other prognostications will also be fulfilled in course of time.
