In the next main division, the Class F spectra, the metallic
lines increase rapidly in prominence, and the hydrogen lines
decrease slightly in strength. These stars are not so blue as
the helium and hydrogen stars. They are intermediate between
the blue stars and the yellow stars, which begin with the next
class, G, of which our Sun is a representative.
The metallic lines are in Class G spectra in great number and
intensity, and the hydrogen lines are greatly reduced in
prominence. The calcium bands are very wide and intense.
Another step brings us to the very yellow and the
slightly-reddish stars, known as Class K. These stars are weak
in violet light, the hydrogen lines are substantially of the
same intensity as the most prominent metallic lines, and the
metallic lines are more and more in evidence.
Stars in the last subdivisions of the Class K and all of the
Class M stars are decidedly red. In these the hydrogen lines
are still further weakened and the metallic lines are even more
prominent. Their spectra are further marked by absorption bands
of titanium oxide, which reach their maximum strength in the
later subdivisions of Class M.
The extremely red stars compose Class N on the Harvard scale.
Their spectra are almost totally lacking in violet light, the
metallic absorption is very strong, and there are conspicuous
absorption bands of carbon.
Deep absorbing strata of titanium and carbon oxides seem to
exist in the atmospheres of the Class M and N stars,
respectively. The presence of these oxides indicates a
relatively low temperature, and this is what we should expect
from stars so far advanced in life.
The period of existence succeeding the very red stars has
illustrations near at hand, we think, in Jupiter, Saturn,
Uranus and Neptune, and in the Earth and the other small
planets and the Moon: bodies which still contain much heat, but
which are invisible save by means of reflected light.
The progression of stellar development, which we have
described, has been based upon the radiation of heat. This is
necessarily gradual, and the corresponding changes of spectrum
should likewise be gradual and continuous. It is not intended
to give the impression that only a few types of spectra are in
evidence: the variety is very great. The labels, Class B, Class
A, and so on to Class N, are intended to mark the miles in the
evolutionary journey. The Harvard experts have put up other
labels to mark the tenths of miles, so to speak, and some day
we shall expect to see the hundredths labeled. Further, it is
not here proposed that heat radiation is the only vital factor
in the processes of evolution. The mass of a star may be an
important item, and the electrical conditions may be concerned.
A very small star and a very massive star may develop
differently, and it is conceivable that there may be actual
differences of composition. But heat-radiation is doubtless the
most important factor.
The evolutionary processes must proceed with extreme
deliberation. The radiation of the heat actually present at any
moment in a large helium star would probably not require many
tens of thousands of years, but this quantity of heat is
negligible in comparison with the quantity generated within the
star during and by the processes of condensation from the
helium age down to the Class M state. We know that the
compression of any body against resistance generates or
releases heat. Now a gaseous star at any instant is in a state
of equilibrium. Its internal heat and the centrifugal force due
to its rotation about an axis are trying to expand it. Its own
gravitational power is trying to draw all of its materials to
the center. Until there is a loss of heat no contraction can
occur; but just as soon as there is such a loss gravity
proceeds to diminish the stellar volume. Contraction will
proceed more slowly than we should at first thought expect,
because in the process of contraction additional heat is
generated and this becomes a factor in resisting further
compression. Contraction is resisted vastly more by the heat
generated in the process of contraction than it is by the store
of heat already in evidence. The quantity of heat in our Sun,
now existing as heat, would suffice to maintain its present
rate of outflow only a few thousands of years. The heat
generated in the process of the Sun's shrinkage under gravity,
however, is so extensive as to maintain the supply during
millions of years to come. Helmholtz has shown that the
reduction of the Sun's radius at the rate of 45 meters per year
would generate as much heat within the Sun as is now radiated.
This rate of shrinkage is so slow that our most refined
instruments could not detect a change in the solar diameter
until after the lapse of 4,000 or 5,000 years. Again, there are
reasons for suspecting that the processes of evolution in our
Sun, and in other stars as well, may be enormously prolonged
through the influence of energy within the atoms or molecules
of matter composing them. The subatomic forces residing in the
radioactive elements represent the most condensed form of
energy of which we have any conception. It is believed that the
subatomic energy in a mass of radium is at least a million-fold
greater than the energy represented in the combustion or other
chemical transformation of any ordinary substance having the
same mass. These radioactive forces are released with extreme
slowness, in the form of heat or the equivalent; and if these
substances exist moderately in the Sun and stars, as they do in
the Earth, they may well be important factors in prolonging the
lives of these bodies.
Speaking somewhat loosely, I think we may say that the
processes of evolution from an extended nebula to a condensed
nebula and from the latter to a spherical star, are
comparatively rapid, perhaps normally confined to a few tens of
millions of years; but that the further we proceed in the
development process, from the blue star to the yellow, and
possibly but not certainly on to the red star, the slower is
the progress made, for the radiating surface through which all
the energy from the interior must pass becomes smaller and
smaller in proportion to the mass, and the convection currents
which carry heat from the interior to the surface must slow
down in speed.
A HISTORY OF FIJI.
BY DR. ALFRED GOLDSBOROUGH MAYER
IV
THE Fijians had a well-organized social system which recognized
six classes of society. (1) Kings and queens (Tuis and Andis).
(2) Chiefs of districts (Rokos). (3) Chiefs of villages,
priests (Betes), and land owners (Mata-ni-vanuas). (4)
Distinguished warriors of low birth, chiefs of the carpenter
caste (Rokolas), and chiefs of the turtle fishermen. (5) Common
people (Kai-si). (6) Slaves taken in battle.
The high chiefs still inspire great respect, and indeed it has
been the policy of the British government to maintain a large
measure of their former authority. Thus of the 17 provinces
into which the group was divided, 11 are governed by high
chiefs entitled Roko Tui, and there are about 176 inferior
chiefs who are the head men of districts, and 31 native
magistrates. In so far as may be consistent with order and
civilization these chiefs are permitted to govern in the old
paternal manner, and they are veritably patriarchs of their
people. The district chiefs are still elected by the land
owners, mata-ni-vanuas, by a showing of hands as of old.
Independent of respect paid to those in authority, rank is
still reverenced in Fiji. Once acting under the kind permission
and advice of our generous friend Mr. Allardyce, the colonial
secretary, and accompanied by my ship-mates Drs. Charles H.
Townsend, and H. F. Moore, I went upon a journey of some days
into the interior of Viti Levu, our guide and companion being
Ratu Pope Seniloli, a grandson of king Thakombau, and one of
the high chiefs of Mbau. Upon meeting Ratu Pope every native
dropped his burdens, stepped to the side of the wood-path and
crouched down, softly chanting the words of the tame, muduo!
wo! No one ever stepped upon his shadow, and if desirous of
crossing his path they passed in front, never behind him. Clubs
were lowered in his presence, and no man stood fully erect when
he was near. The very language addressed to high chiefs is
different from that used in conversation between ordinary men,
these customs being such that the inferior places himself in a
defenceless position with respect to his superior.
It is a chief's privilege to demand service from his subjects;
which was fortunate for us, for when we started down the
Waidina River from Nabukaluka our canoes were so small and
overloaded that the ripples were constantly lapping in over the
gunwale, threatening momentarily to swamp us. Soon, however, we
came upon a party of natives in a fine large canoe, and after
receiving their tama Ratu Pope demanded: "Where are you going"?
The men, who seemed somewhat awestricken, answered that it had
been their intention to travel up the river. Whereupon Ratu
Pope told them that this they might do, but we would take their
canoe and permit them to continue in ours. To this they acceded
with the utmost cheerfulness, although our noble guide would
neither heed our protests nor permit us to reward them for
their service, saying simply, "I am a chief. You may if you
choose pay me." In this manner we continued to improve our
situation by "exchanging" with every canoe we met which
happened to be better than our own, until finally our princely
friend ordered a gay party of merry-makers out of a fine large
skiff, which they cheerfully "exchanged" for our leaky canoes
and departed singing happily, feeling honored indeed that this
opportunity had come to them to serve the great chief Ratu Pope
Seniloli; and thus suffering qualms of conscience, we sailed to
our destination leaving a wake of confusion behind us. Moreover
I forgot to mention that many natives had by Ratu Pope's orders
been diverted from their intended paths and sent forward to
announce the coming of himself and the "American chiefs." Thus
does one of the Royal house of Mbau proceed through Fiji.
At first sight such behavior must appear autocratic, to say the
least, but it should be remembered that a high chief has it in
his power fully to recompense those about him, and this without
the payment of a penny. Indeed, many intelligent natives still
regret the introduction of money into their land, saying that
all the white man's selfishness had been developed through its
omnipotence. In Fiji to-day there are no poor, for such would
be fed and given a house by those who lived beside them. The
white man's callous brutality in ignoring the appeal of misery
is incomprehensible to the natives of Fiji. "Progress" they
have not in the sense that one man possesses vast wealth and
many around him struggle helplessly, doomed to life-long
poverty; nor have they ambition to toil beyond that occasional
employment required to satisfy immediate wants. Yet if life be
happy in proportion as the summation of its moments be
contented, the Fijians are far happier than we. Old men and
women rest beneath the shade of cocoa-palms and sing with the
youths and maidens, and the care-worn faces and bent bodies of
"civilization" are still unknown in Fiji. They still have
something we have lost and never can regain.
It is impossible to draw a line between personal service such
as was rendered to Ratu Pope and a regular tax (lala) for the
benefit of the entire community or the support of the communal
government; and the recognition of this fact actuated the
English to preserve much of the old system and to command the
payment of taxes in produce, rather than in money.
Land tenure in Fiji is a subject so complex that heavy volumes
might be written upon it. In general it may be said that the
chief can sell no land without the consent of his tribe.
Cultivated land belonged to the man who originally farmed it,
and is passed undivided to all his heirs. Waste land is held in
common. Native settlers who have been taken into the tribes
from time to time have been permitted to farm some of the waste
land, and for this privilege they and their heirs must pay a
yearly tribute to the chief either in produce or in service.
Thus this form of personal lala is simply rent. The whole
subject of land-ownership has given the poor English a world of
trouble, as one may see who cares to read the official reports
of the numerous intricate cases that have come before the
courts.
For example, one party based their claims to land on the
historic fact that their ancestors had eaten the chief of the
original owners, and the solemn British court allowed the
claim.
Basil Thomson in his interesting work upon "The Fijians; a
Study of the Decline of Custom," has given an authoritative
summary of the present status of taxation and land tenure, land
being registered under a modification of the Australian Torrens
system.
In order to protect these child-like people from the avarice of
our own race they are not permitted to sell their lands, and
the greater portion of the area of Fiji is still held by the
natives. The Hawaiian Islands now under our own rule furnish a
sad contrast, for here the natives are reduced by poverty to a
degraded state but little above that of peonage. The Fijians.
on the other hand, may not sell, but may with the consent of
the commissioner of native affairs lease their lands for a
period of not more than twenty years.
The Fijians appear never to have been wholly without a medium
of exchange, for sperm-whale's teeth have always had a
recognized purchasing power, but are more especially regarded
as a means of expressing good will and honesty of purpose. A
whale's tooth is as effective to secure compliance with the
terms of a bargain as an elaborately engraved bond would be
with us. More commonly, however, exchanges are direct, each man
bringing to the village green his taro, yaqona, yams or fish
and exchanging with his neighbors; the rare disputes being
settled by the village chief.
In traveling you will discover no hotels, but will be
entertained in the stranger's houses, and in return for your
host's hospitality you should make presents to the chief.
Indeed to journey in good fashion you should be accompanied by
a train of bearers carrying heavy bags full of purposed gifts,
and nowhere in the world is the "rate per mile" higher than in
Polynesia.
As in all communities, including our own world of finance, a
man's wealth consists not only in what he possesses but even
more so in the number of people from whom he can beg or borrow.
Wilkes records an interesting example of this, for he found
that the rifle and other costly presents he had presented to
King Tanoa were being seized upon by his (Tanoa's) nephew who
as his vasu had a right to take whatever he might select from
the king's possessions. Indeed, in order to keep his property
in sight, Tanoa was forced to give it to his own sons, thus
escaping the rapacity of his nephew. The construction of the
British law is such that a vasu who thus appropriates property
to himself could be sued and forced to restore it, but not a
single Fijian has yet been so mean as to bring such a matter
into court.
An individual as such can hardly be said to own property, for
nearly all things belong to his family or clan, and are shared
among cousins. This condition is responsible for that absence
of personal ambition and that fatal contentment with existing
conditions, which strikes the white man as so illogical, but
which is nevertheless the dominant feature of the social fabric
of the Polynesians, and which has hitherto prevented the
introduction of "ideals of modern progress." The natives are
happy; why work when every reasonable want is already supplied?
None are rich in material things, but none are beggars
excepting in the sense that all are such. No one can be a
miser, a capitalist, a banker, or a "promoter" in such a
community, and thieves are almost unknown. Indeed, the honesty
of the Fijians is one of those virtues which has excited the
comment of travelers. Wilkes, who loathed them as "condor-eyed
savages," admits that the only thing which any native attempted
to steal from the Peacock was a hatchet, and upon being
detected the chief requested the privilege of taking the man
ashore in order that he might be roasted and eaten. Theft was
always severely punished by the chief; Maafu beating a thief
with the stout stalk of a cocoanut leaf until the culprit's
life was despaired of, and Tui Thakau wrapping one in a tightly
wound rope so that not a muscle could move while the wretch
remained exposed for an entire day to the heat of the sun.
During Professor Alexander Agassiz's cruises in which he
visited nearly every island of the Fijis, and the natives came
on board by hundreds, not a single object was stolen, although
things almost priceless in native estimation lay loosely upon
the deck. Once, indeed, when the deck was deserted by both
officers and crew and fully a hundred natives were on board, we
found a man who had been gazing wistfully for half an hour at a
bottle which lay upon the laboratory table. Somehow he had
managed to acquire a shilling, a large coin in Fiji, and this
he offered in exchange for the coveted bottle. One can never
forget his shout of joy and the radiance of his honest face as
he leaped into his canoe after having received it as a gift.
Even the great chief Ratu Epele of Mbau beamed with joy when
presented with a screw-capped glass tobacco jar, and Tui Thakau
of Somo somo had a veritable weakness for bottles and possessed
a large collection of these treasures.
Intelligent and well-educated natives who know whereof they
speak have told me that they desire not the white man's system,
entailing as it does untold privation and heart-burnings to the
many that the few may enjoy a surfeit of mere material things.
As the natives say, "The white man possesses more than we, but
his life is full of toil and sorrow, while our days are happy
as they pass."
Thus in the Pacific life is of to-day; the past is dead, and
the future when it comes will pass as to-day is passing. Life
is a dream, an evanescent thing, all but meaningless, and real
only as is the murmur of the surf when the sea-breeze comes in
the morning, and man awakens from the oblivion of night.
Hoarded wealth inspires no respect in the Pacific, and indeed,
were it discovered, its possession would justify immediate
confiscation. Yet man must raise idols to satisfy his instinct
to worship things above his acquisition, and thus rank is the
more reverenced because respect for property is low. Even
to-day there is something god-like in the presence of the high
chiefs, and none will cross the shadow of the king's house.
Even in war did a common man kill a chief he himself was killed
by men of his own tribe.
As it is with property so with relationships. The family ties
seem loosened; every child has two sets of parents, the adopted
and the real, and relationships founded upon adoption are more
respected than the real. Rank descends mainly through the
mother. The son of a high chief by a common woman is a low
chief, or even a commoner, but the son of a chieftainess by a
common man is a chief. Curiously, there are no words in Fijian
which are the exact equivalent of widow and widower. In the
Marshall group the chief is actually the husband of all the
women of his tribe, and as Lorimer Fison has said in his "Tales
from Old Fiji," their designation and understanding of
relationships suggests that there was once a time when "all the
women were the wives of every man, and all the men were the
husbands of every woman," as indeed was almost the case in
Tahiti at the time of Captain Cook's visit to this island.
The social customs of Fiji are rarely peculiar to Fiji itself,
but commonly show their relationship or identity with those of
the Polynesians or Papuans. Curiously indeed, while the
original stock of the Fijians was probably pure Papuan, their
social and economic systems are now dominated by Polynesian
ideas, and only among the mountain tribes do we find a clear
expression of the crude Papuan systems of life and thought.
This in itself shows that under stimulation the Fijians are
capable of advancement in cultural ideals.
This superposition of a Polynesian admixture upon a barbarous
negroid stock may account for the anomalous character of the
Fijians, for in the arts they equalled or in some things
excelled the other island peoples of the Pacific, and some of
their customs approached closely to the cultural level of the
Polynesians, but in certain fundamental things they remained
the most fiendish savages upon earth. Indeed we should expect
that contact with a somewhat high culture would introduce new
wants, and thus affect their arts more profoundly than their
customs.
In common with all primitive peoples, their names of men and
women are descriptive of some peculiarity or circumstance
associated with the person named. Indeed, names were often
changed after important events in a person's life, thus our old
friend Thakombau began life as Seru, then after the coup d'etat
in which he slaughtered his father's enemies and reestablished
Tanoa's rule in Mbau he was called Thakombau (evil to Mbau). At
the time he also received another name Thikinovu (centipede) in
allusion to his stealthiness in approaching to bite his enemy,
but this designation, together with his "missionary" name
"Ebenezer," did not survive the test of usage. Miss Gordon
Cumming gives an interesting list of Fijian names translated
into English. For women they were such as Spray of the Coral
Reef, Queen of Parrot's Land, Queen of Strangers, Smooth Water,
Wife of the Morning Star, Mother of Her Grandchildren, Ten
Whale's Teeth, Mother of Cockroaches, Lady Nettle, Drinker of
Blood, Waited For, Rose of Rewa, Lady Thakombau, Lady Flag,
etc. The men's names were such as The Stone (eternal) God,
Great Shark, Bad Earth, Bad Stranger, New Child, More Dead
Man's Flesh, Abode of Treachery, Not Quite Cooked, Die Out of
Doors, Empty Fire, Fire in the Bush, Eats Like a God, King of
Gluttony, Ill Cooked, Dead Man, Revenge, etc.
In the religion of a people we have the most reliable clue to
the history of their progress in culture and intelligence, for
religions even when unwritten are potent to conserve old
conceptions, and thus their followers advance beyond them, as
does the intelligence of the twentieth century look pityingly
upon the conception of the cruel and jealous God of the Old
Testament, whose praises are nevertheless still sung in every
Christian church. Thus in Tahiti the people were not cannibals,
but the gods still appeared in the forms of birds that fed upon
the bodies of the sacrificed. The eye of the victim was,
indeed, offered to the chief, who raised it to his lips but did
not eat it. In Samoa also where the practice of cannabalism was
very rare and indulged in only under great provocation, some of
the gods remained cannibals, and the surest way of appeasing
any god was to be laid upon the stones of a cold oven. In
Tahiti and Samoa, while most of the gods were malevolent, a few
were kindly disposed towards mortals; in Fiji, however, they
were all dreaded as the most powerful, sordid, cruel and
vicious cannibal ghosts that have ever been conjured into being
in the realm of thought.
All over the Pacific from New Zealand to Japan, and from New
Guinea to Hawaii, ancestor-worship forms the backbone of every
religion as clearly as it did in Greece or Rome. There are
everywhere one or more very ancient gods who may always have
existed and from whom all others are descended. Next in order
of reverence, although not always in power, come their
children, and finally the much more numerous grandchildren and
remote descendants of these oldest and highest gods. Finally,
after many generations, men of chieftain's rank were born to
the gods. Thus a common man could never attain the rank of a
high chief, for such were the descendants of the gods, while
commoners were created out of other clay and designed to be
servants to the chiefs.
But the process of god-making did not end with the appearance
of men, for great chiefs and warriors after death became kalou
yalo, or spirits, and often remained upon earth a menace to the
unwary who might offend them. Curiously, these deified mortals
might suffer a second death which would result in their utter
annihilation, and while in Fiji we heard a tale of an old chief
who had met with the ghost of his dead enemy and had killed him
for the second and last time; the club which served in this
miraculous victory having been hung up in the Mbure as an
object of veneration.
Of a still lower order were the ghosts of common men or of
animals, and most dreaded of all was the vengeful spirit of the
man who had been devoured. The ghosts of savage Fiji appear all
to have been malevolent and fearful beings, whereas those of
the more cultured Polynesians were some of them benevolent. As
Ellis says of the Tahitian mythology:
