In this connection, it is interesting to observe that creatures endowed

with the highest intelligence, both vertebrate and invertebrate, manage

to survive in considerable numbers in regions devoid of water. One

conveys it to his habitations from lower levels, the other digs wells

or manages to utilize the moisture from the roots of trees.

MY OWN WORK

_Snow caps of solid carbonic acid gas, a planet cracked in

a positively monomaniacal manner meteors ploughing tracks

across its surface with such mathematical precision that

they must have been educated to the performance, and so

forth and so on, in hypotheses each more astounding than

its predecessor, commend themselves to man, if only by such

means he may escape the admission of anything approaching

his kind._

PERCIVAL LOWELL.

I am led to present these few brief memoranda of my own work in order

to meet questions which would naturally be asked as to whether I had

ever seen Mars through a telescope, and if so did I make out any

markings or canals.

[Illustration: PLATE VII

DOME OF THE LOWELL OBSERVATORY, FLAGSTAFF, ARIZONA]

It was my good fortune to have the privilege of observing Mars every

night at the Lowell Observatory (see Plate VII) for thirty-four days,

covering an almost complete presentation of the planet. A few nights

were cloudy and no observations were made. With these exceptions I

was in the observer's chair several times each evening. The twenty-four

inch refractor of which I had the use was the last telescope Clark

ever made, and he pronounced it his best one. This instrument (Plate

VIII) is mounted on a mesa near the town of Flagstaff, Arizona, at

a height of over 7,000 feet above sea-level, in an atmosphere of

remarkable clarity and steadiness. I have already stated on page 80

my first experiences in observing and will only present the brief

notes I made at the time of observation. Better results would have

accompanied these efforts had I followed the custom of Michael Faraday

and asked what was I to look at, what was I expected to see? I had been

somewhat prejudiced as to the existence of the canals by the comments

of sporadic observers, many of whom, by the way, had never been able to

see them, and denying that any one else ever had, straightway proceeded

to suggest a theory to explain their presence! Careful to avoid any

bias in the matter I rigidly refused to allow either Professor Lowell

or his assistants to suggest where I might find a canal or a marking on

the disk. The night before I left the Observatory for home I asked Mr.

Lowell for the first time, to indicate the position of some conspicuous

canal which I had not seen. This he did and examining the region

which I supposed he had indicated on the disk I searched in vain for

the line. In doing so another line was detected and drawn, and on

confessing my failure to see the line he had described, showed him my

drawing, when he exclaimed, "Why, you have got it," and sure enough

when he showed me his drawing and repeated the directions he had given

me, I found that I had been looking at the wrong pole of the planet.

[Illustration: PLATE VIII

TWENTY-FOUR INCH TELESCOPE OF THE LOWELL OBSERVATORY, FLAGSTAFF,

ARIZONA]

In one stage of great discouragement I came across a statement made

by Mr. A. Stanley Williams which has already been quoted, namely,

that he had to observe continually for two months before sufficient

sensitiveness enabled him to make out the more delicate markings. That

I might have seen more had I been acclimated, and had been accustomed

to telescopic observation there is no doubt. The record is poor enough

and yet under the conditions mentioned the results may be of interest

to the reader.

May 14. Midnight. Saw planet for the first time. A beautiful

luminous disk with shades of tone dimly visible. Southern

pole cap white and seen.

May 15. Certain details sufficiently distinct to make out dark

areas, and at times a line or two.

May 16. Occasional flashes of a few lines, while broad darkened

area and cuniform area on right visible, and, in one flash,

a line supporting the wedge as well as basal line. With no

better seeing conditions than last night, more details came

out, and for the first time I am encouraged to believe that

each day an improvement will take place. I saw enough to

make my first drawing.

May 17. Bad seeing. I made out only the broad southern band,

the line at the northern pole and the wedge-shaped area to

the right below, also a slight discoloration in the middle.

May 18. Not very good seeing. Could make out but little more

than I did last night.

May 19. Seeing about the same, perhaps slightly less. Saw rift

in southern dark band and north pole appeared luminous.

May 20. Mr. Lowell informed me this morning that the luminous

appearance around the north pole that I saw last night

was the result of a snowstorm. Seeing fair. Considerable

vibration of planet. Saw new snow field of the northern

pole distinctly outlined and much confused markings. Looked

in vain for spots but could not discern them.

May 21. Seeing clearer, and for the first time I made out

distinctly two spots, or oases. Mr. Lowell informed me that

Schiaparelli had never seen them. The snow which fell on

May 19 was still conspicuous.

May 22. With a headache and a seedy condition from not being

acclimated, I yet found an improvement in my seeing

capacities. I made out a promontory in the southern dark

belt, also a canal running down from the Trivium.

May 23. Bad seeing. Could not define snow cap though dark

southern band showed. Made no drawing.

May 24. Am in despair of seeing anything when the others see so

much. I must have an old and worn-out retina. In looking,

lines flash out at times but it is impossible to locate

them. I can certainly see more than Huyghens did, but not

much more.

May 25. Heavens very cloudy and Mars obscured.

May 26. Poor seeing--saw but a few markings.

May 27. Snow and hail storm in the afternoon. Temperature 35°

at night. Seeing zero, and consequently no observation.

May 30. To-night markings and more particularly shades seemed

abundant yet so evanescent that only an intimate knowledge

by long study could define them. I gave up in despair.

May 31. Saw a little more than I saw last night but did not see

a trace of things that Mr. Lowell and his assistants

apparently saw without effort. I realize that it requires

a special training to observe the flickering evanescent

markings on Mars.

June 1. Though the best night yet for steady atmosphere I saw

but little more and have come to the conclusion that it

will take months of continuous observation before I can see

anything.

June 2. I went to the Observatory to-night in despair of ever

seeing anything more. Got into the observing chair and

immediately saw a number of markings I had not seen before,

as my drawings show. I have purposely refrained from

studying the maps, and so do not know the names of the

lines detected.

June 3. Atmosphere so unsteady that it was impossible to make

anything out of Mars, so after struggling awhile gave it up

in disgust.

June 4. Seeing about 4, yet manage to see a few planetary

details.

June 5. I find a slow advance in my ability to see the markings

though it is exasperating that the janitor of the

Observatory talks about plainly seeing certain details

which he indicates to me by a sketch, and looking at the

region I can see no trace of a canal or anything else.

June 7. Seeing very good and in my observations tonight added

another canal. It is a most difficult matter to catch the

fleeting lines as they appear with startling distinctness

to instantly vanish again.

June 9. Seeing fairly good. Could make out but little more.

Color of regions very strong and vivid.

June 10. Seeing a little better than last night. Added three new

canals, and these canals flashed out three or four times

before I was willing to record them, and then I did not

believe them till Mr. Lowell showed me a drawing he had

made just before, and the two drawings corresponded.

June 11. Looked at eight o'clock and the markings of larger

features came out strong and dark and yet the seeing was

not estimated high.

June 12. Rather poor seeing though some of the dark regions came

out with remarkable distinctness. Every day I notice a very

slight improvement in detecting lines. Markings formerly

made out with great difficulty are now instantly recognized.

June 13. In my observations to-night added one new canal and

completed another, and was able to detect one that Mr.

Lowell had not seen during the evening--a well-known one he

says. It simply shows that one must continually observe as

the lines flash out for a single instant.

June 14. Made out still another canal to-night. The markings

show very clear, in fact some parts were vivid in

distinctness and the lower part of Syrtis Major dark blue.

June 15. Poor seeing, yet I was able to see a few of the

prominent features and defined the wedge-shaped region

below.

On Plate IX I give a few of my drawings of Mars in which are indicated

the lines I saw many times and was able to fix. Other lines flashed out

for an instant but these were not recorded, simply because I could not

definitely locate them.

The expression "poor seeing" in the above notes must be taken in

a comparative sense with relation to the usual conditions of the

atmosphere of Flagstaff. Poor seeing, therefore, at Flagstaff would

be equal, if not superior, to the best seeing at much lower levels.

An astronomer who resigned his position in a western observatory for

duties at Mount Wilson, California, told me that for thirty consecutive

nights the seeing was superior to the best nights he had observed in at

his former post.

WHAT THE MARTIANS MIGHT SAY OF US

_O wad some power the giftie gie us,

To see oursels as others see us!_

ROBERT BURNS.

For every single perplexity of interpretation we encounter in our study

of the surface markings of Mars, the Martian would encounter a dozen

perplexities in interpreting the various features on the surface of the

Earth.

Admitting the conclusions of Lowell of the existence of intelligence in

Mars, and that that intelligence has been associated for ages with a

planet having only slight elevations of land, a tenuous atmosphere, a

scarcity of water which has been utilized for ages through artificial

channels, as we have done in various parts of the world since

prehistoric times, having vast tracts of sterile plains, and, within

these sterile tracts large oases fed by irrigating canals, regions of

sparse vegetation, and no large bodies of water; with these conditions

going beyond the history of these intelligences, what must be the

Martian interpretation of the surface features of this world? It is

a perfectly fair inquiry, for by such means we may appreciate the

attitude of some of our interpreters of Mars.

In examining the Earth, then, as we have examined Mars, the Martian

would find large yellow and reddish areas, extensive greenish areas,

and, besides, large regions of varying shades of blue, possibly,

occupying three-fourths of the Earth's surface. The yellow areas he

would interpret as desert land, the greenish areas he might consider

vegetation, but what would he make out of the larger regions of blue?

This would certainly puzzle him, because, unfamiliar with oceans, he

could not believe that such vast tracts could really be water. He would

easily interpret the polar snow caps, and the waters at their edges,

but the oceans would be impossible to solve. The suggestion, by some

audacious interpreter, that this vast blue area was water, would be

answered by showing that these so-called bodies of water bordered vast

tracts of sandy deserts with no canals running into them for irrigation

or navigation purposes. Even the polar snow caps would be doubted,

because they seemed to extend far down into temperate latitudes; and on

their recedence in summer, there would be seen no dark, bordering seas

as the result of their melting. The vegetation, instead of unfolding

at the north and gradually extending southward, would unfold in a

contrary direction, appearing first in south temperate latitudes and

developing northward. The perennial character of the vegetation in the

tropics would puzzle him. Even if he recognized oases in the deserts

of America and Africa, the results of Artesian wells or springs,

he could not believe them to be vegetation; for he would detect no

irrigating canals running into them. He would come to the conclusion

that no creature could possibly exist on the Earth, as the tremendous

force of gravitation with great atmospheric pressure would forbid

the existence of any organic forms. The immense clouds veiling the

surface must at times suffer condensation, and the impact of raindrops

would, from their velocity and weight, smash everything in the way of

life. Life, if it existed in forms supported by appendages, must have

legs of iron to sustain its weight, and a crust like a turtle to be

impervious to raindrops, and this would be contrary to all Martian

analogy. The courses of rivers, if detected, would puzzle him from

their irregularity, unless he dared to suggest that these long sinuous

channels extending for thousands of miles were identical to the little

rivulets he had studied near his own poles.

In fact, about the only feature outside the polar snow caps that

he would instantly recognize, would be the great ice cap of the

Himalayas. India, that vast region extending from latitude 35° nearly

to the equator, with its great plains and sterile regions, with its

overpowering heat, and a dense population, depends for the sustenance

of many of its millions upon the thousands of miles of irrigating

canals, fed from the melting snow caps of the Himalayas. India has no

great lakes, but in the northern plains great rivers course their way

to the sea. The Ganges and the Indus and their tributaries derive their

waters from the melting glaciers, and from these, a most extensive

irrigating system of canals and reservoirs draw their waters. As

the heat increases the ice melts more rapidly, and so more water is

supplied at just the time when it is most needed. The whole scheme is

on so vast a scale that a Martian would recognize its meaning, though

he would wonder at the tortuous outlines of the larger canals.

Flammarion has, in a similar manner, presented the arguments of Martian

astronomers as to whether life exists anywhere but upon the planet

Mars. He says, among other fancies, that the sapient Martian argues

that houses could not be built on the Earth, on account of the violence

with which building materials, such as bricks, blocks, etc., would

drop, and thus endanger life. Believing that Mars is rightly balanced

as to temperature, the Earth being so much nearer the Sun, would be too

hot for life to exist. The Martian conceives himself to be supremely

complete "even to the point that artists wishing to represent God in

our sanctuaries have figured Him in the image of a Martian man." The

Martian considers our year too short. In his reflections he says:

"During the period in which one of us attains the middle age of fifty

years those on Earth have become decrepit old men of ninety-four, if,

indeed, they are not already dead."

Seriously, if there is an intelligence in Mars, it must have evolved

along the same general lines as intelligence has developed on the

Earth. Being an older planet, it must have outgrown many of the

vagaries and illusions which still hamper man in his progress here.

In the dim past, however, we can imagine some Martian astronomer with

the enigma of our Earth before him, and the great vault of heaven with

its thousands of riddles unanswered, consulting records and covering

pages with mathematical formulæ to ascertain the precise spot upon

which grew the bean stalk by which a Martian Jack ascended to encounter

the giant. Indeed, the imagination can conjure up an infinite number of

parallels. If Mars is an older sphere, we trust it has long outgrown

the superstitions which still hamper man in his interpretation of the

inexorable phenomena of Nature on this little planet. We may hope

that they have finally reached that stage when a dictum similar to

that of Huxley forms an engraved tablet in their temples of worship.

These are his words: "Science is teaching the world that the ultimate

court of appeal is observation and experiment, and not authority. She

is teaching it to estimate the value of evidence; she is creating a

firm and living faith in the existence of immutable moral and physical

laws, perfect obedience to which is the highest possible aim of an

intelligent being."

SCHIAPARELLI, LOWELL, PERROTIN, THOLLON

_Every age has its problem, by solving which humanity is

helped forward._

HEINRICH HEINE.

In previous pages allusion has been made to the distinguished character

of the astronomers who have contributed to a knowledge of the surface

markings of Mars. Testimony from astronomical sources has been quoted

as to their keen-sightedness in this work which, as Sir Robert Ball

has said, "indicates one of the utmost refinements of astronomical

observation." That the reader may better understand the eminence

of some of those whose names will forever be associated with the

investigation of the surface features of Mars the following brief

records are given.

[Illustration: GIOVANNI VIRGINIO SCHIAPARELLI]

The two astronomers most widely known in connection with the study of

Mars are Professor Giovanni Schiaparelli and Professor Percival

Lowell. Lowell had just graduated from Harvard, at the age of

twenty-one, when Schiaparelli, at the age of forty-two, made his

first great discovery of the _canali_ of Mars. Macpherson, in his

valuable history of the "Astronomers of To-day," says of Schiaparelli:

"His studies of meteoric astronomy, of Mars, Venus, and Mercury, of

double stars and of stellar distribution, have given him a place

second to none among living students of the heavens." From the same

interesting book we gather the following facts: Schiaparelli was born

in Sabigliano, in Piedmont, in 1835. He attended the usual schools in

his native town and then entered the University of Turin as a student

of mathematics and architecture. Before he was twenty years old he

decided to devote himself to the study of astronomy. At the age of

twenty-four he was an assistant in the celebrated Observatory of

Pulkova. When the kingdom of Italy was organized he became an assistant

in the Brera Observatory, Milan. He became suddenly famous at the age

of twenty-seven by the discovery of a new asteroid. In 1862 he became

Director of the Observatory. Schiaparelli's first great discovery was

the relationship between comets and meteoric showers. In 1872 he was

accorded the gold medal of the Royal Astronomical Society for his

various astronomical discoveries. Professor Simon Newcomb gives him

high praise when he says: "Among the individual observers Schiaparelli

may be assigned the first place in view of his long continued study of

the planets under a fine Italian sky, the conscientious minuteness of

his examinations, and his eminence as an investigator." Schiaparelli's

researches into the relation of comets and meteors "were developed

in 1873, in his remarkable work 'Le Stelle Cardenti,' which is,

according to Sir Norman Lockyer, one of the greatest contributions to

astronomical literature which the nineteenth century has produced."

Macpherson closes his interesting memoir of Schiaparelli by saying:

"His devotion to astronomy, his singularly accurate observations and

his wonderful discoveries have secured for him an exalted position

among the greatest astronomers of modern times." For a further

appreciation of the work of Schiaparelli the reader is referred to

Macpherson's "Astronomers of To-day." In this brief sketch the reader

may judge of the eminent character of one who insists that the lines

in Mars are a persistent feature of its surface, whatever one's

interpretation of them may be.

[Illustration: PERCIVAL LOWELL]

Percival Lowell was born in Boston in 1855. He was graduated from

Harvard in 1876, and prepared for his graduating thesis an essay on

the Nebular Hypothesis. Lowell is a many-sided man. Early interested

in mathematics, he became one of the founders of the Mathematical and

Physical Society of Boston. A visit to Japan, where he lived a number

of years, resulted in the writing of three interesting books: "The Soul

of the Far East," 1886; "Noto," 1891; and "Occult Japan," 1894. During

his residence in Japan he was chosen foreign Secretary and adviser to

the Korean Special Commission, then about to visit the United States,

which he accompanied. On his return to Korea he was the guest of the

Korean Government, and this experience prompted him to write "A Korean

Coup d' État," 1894, and his well-known volume, "Choson, the Land of

the Morning Calm," 1885. On his return to America he undertook an

eclipse expedition to Tripoli with Professor Todd. His early interest

in astronomical subjects was now fully awakened, and the red planet,

which he had observed in boyhood with a small telescope from the roof

of his father's house, aroused his interest on account of the heated

discussions over Schiaparelli's discoveries. With an impetuosity and

enthusiasm which characterizes all his work, he set about to secure a

proper region and a sufficient elevation for an observatory site. This

was found in northern Arizona at an elevation of over 7,000 feet. Here,

then, was established the Lowell Observatory with a twenty-four inch

refractor made by Clark especially for this Observatory, the last, and,

according to the maker's words, the best telescope he had ever made.

Lowell insisted that the location of an observatory was a much more

important factor than the size of the instrument, and says: "When this

is recognized, as it eventually will be, it will become the fashion to

put up observatories where they may see rather than be seen." It may be

said with truth that, for the first time in the history of astronomy,

an observatory has been erected and fitted for the special purpose of

studying the surface features of Mars. During unfavorable oppositions

Lowell has turned his attention to the other planets, notably Mercury

and Venus, with the result of adding many new and interesting details

concerning these bodies. Three volumes of quarto memoirs and many

bulletins from the Lowell Observatory attest to his industry. He has

been fortunate in securing talented assistants, and their contributions

may be found in the various publications of the Observatory. The

character and importance of Lowell's work may be understood by stating

that the "British Nautical Almanac" is to adopt for the future the

value of the position of the axis of Mars, and the tilt of the planet's

equator to its ecliptic, which was furnished by Professor Lowell in

compliance with a request.

Mr. Lowell is a Fellow of the American Academy of Arts and Sciences;

Member of the Royal Asiatic Society of Great Britain; American

Philosophical Society; Société Astronomique de France; American

Astronomical and Astrophysical Society; Astronomische Gesellschaft;

Société Belge d'Astronomie; Fellow of the American Geographical

Society; Honorary Member Sociedad Astronomica de Mexico; and others.

In 1904 he was awarded the Janssen medal of the Astronomical Society of

France for his researches on Mars.

Mr. Macpherson, in his memoir on Lowell, says that "Mr. Lowell, by his

unwearied devotion to astronomy, has already gained for himself an

enduring reputation."
