THE JOURNAL OF THE ROYAL SOCIETY OF WESTERN AUSTRALIA. VOL. V. Presidential Address. By William J. Hancock, M.Inst.C.E., M.I.E.E. (Delivered 10 th June, 1919.) Ladies and Gentlemen — On nay retirement from the position of President of the Society, I wish to state how highly 1 have appreciated the honour which you conferred on me, and I take this opportunity of thanking the members of Council, officers and members, for their kind- ness and consideration in helping me to carry on the work of the Society. We art 1 greatly indebted to those members who have presented papers during the season. The papers have been of not only great interest but of wider range than heretofore, and I feel sure it is a step in the right direction. 1 cannot but think that all matters affecting the general welfare and betterment of the con- ditions of life come within the scope and functions of our Society equally with matters of scientific interest, whether they be sub- jects of historic interest to guide us, research work of the present, or problems of the future, to consider. The field of the Society is wide, and extending with the progress of science and knowledge. The papers presented to the Society this year have been of a varied character. The first this session was by Professor W oolnough on the “Physiographic Elements of the Swan Coastal 2 Plain/’ a paper throwing light on the geological history of this portion of the State. Mr. J. S. Battye’s paper on “Causes which led to the Col- onisation of Western Australia” was a valuable contribution 1o the history of our State, and brought before us the need ut some organisation to save from oblivion many of the interesting docu- ments, sketches, photographs and data concerning the early settle- ment of the Colony. As the number of the early settlers is rapidly decreasing, effort s should be made to collect and sort out historic data before it is too late. Mr. \Y. Kingsmill brought before the Society the subject of •• Acclimatisation and the very interesting work which has been carried out under his directions. This work is not only of great interest but is also of economic value to the State, and it is to be regretted that it is so little known or appreciated by the public. “Some aspects of Town Manning” was the subject of a paper by Mr. W. A. Saw, a subject which is slowly but surely being realised as an important factor in our lives. The improvement in environment must increase the health and happiness of the com- munity, and minimise the production of the criminal element. In the building up of our towns and cities we all realise the necessity to prevent the growth of slum conditions. Professor Dakin’s paper on his investigations into a serious form of sheep disease dealt with a subject of considerable import- ance and economic value to the State. A paper by Mr. A. R. L. Wright on “Houses in Western Aus- tralia” dealt with a subject which is of general interest. The climate and other conditions naturally must affect the design and arrangements of our homes. One of the most interesting papers read during the session was presented by Mr. D. A. Herbert on the “Xuylsia floribunda , its structure and its parasitism,” m which lie pointed out its para- sitical functions, and at last cleared up the mystery which has surrounded this well known tree for so many years. The last paper of the session was read by Professor Ross on “Light and the Ether” in which he explained the interesting theory recently advanced Avhieh threw doubt on the usually accepted theory that a ray of light travels through the ether of space in a straight line, and the especial interest in this year’s Solar Eclipse, in the attempt of astronomers to answer this question. I think the Society may be congratulated on this list of papers, and I trust that in the future we may have many papers of a similar nature affecting this land of ours, which is rich in rare and interesting subjects. No time should he lost in collecting data, as much of the fauna and flora is rapidly disappearing before what we are pleased to call civilisation. 3 The natural history of Australia stands out unique from other parts of the world. The evolution which has produced so many changes in other lands appears in this Island Continent to have almost stood still or moved but slowly. This may be due to its separation from Asia before the Carnivora appeared there. In- deed, the extraordinarily slow development in Australia points to what an immensely important factor Carnivora must have been in the great struggle for existence and survival of the fittest in the great process of evolution. While the mammals of other lands are absent in Australia, the earliest forms of vertebrate mammals in the fossil beds of Europe are represented by the marsupial Kangaroo of to-day. Many of the Birds, Fishes, and Crustacea of Australia living at the present time have long ceased to exist in other parts of the world. In the Vegetable Kingdom, also, plants of the long past Carboniferous age are still represented in living form in Australia, whilst our aboriginal men do not appear to have evolved very far from their Stone-age ancestors. I have alluded to these conditions so as to indicate how wide and unique is our field of natural history, to raise our interest and enthusiasm, to advocate study and record, for it is one of the functions of our Society to stimulate and assist research in this wonderland of nature. SCIENCE AND CIVILISATION I feel that at the termination of the Great War it will be opportune to bring before you, for your consideration, a few points in connection with science and its relation to progress and civilisation. In referring to the events of last year it is impossible to think of any work or progress which has not been connected with or affected by the Great War. Each of my predecessors took for his Presidential address some of the educational or industrial problems which could he expected to arise after such a struggle, and now that the war is practically over, the problems of Peace are found to be more serious and more complex tlian those of the War. The termination of the V ar has come perhaps more completely and more suddenly than was anticipated. It could hardly have been expected that the German Navy would surrender without a fight, and be interned in a British harbour, and that the Allies would so soon be in occupation of the cities of the Kliine. As the War involved a greater number and variety of nations than any previous war, so the problems of Peace must affect every country of the world, for the spread of international commerce, with the rapid means of communication by railway, steamer, post and telegraphs, make any treaty or agreement between nations a matter of world -wide consequence. 4 We have to go back to the Wars of Napoleon to witness the breaking up of Empires and the creation of new States on any- thing like the scale of last year. The Prussian victory over the French in 1870-1 consummated the federation of the separate German States into one German Empire, and the defeat of the Germans last year broke up that Empire into separate States again. I. think there is little doubt that the separate German States, possessing common interests, language and ideals, will coalesce, probably with the addition of Austria, into a United States of Germany, and if this is the right view it should make us all the more careful to look at our own position, to see that we do not lag behind in the march of Progress in Peace and War. We cannot build any hope that the War of 1914 will alter human ideas or change mankind, nor that the late war will be the last one; we can only hope to postpone such a calamity as long as possible. The change of the various types of Government in Europe into more Democratic and Socialistic forms, whether they prove permanent or not, must have an influence on our own National organisation and that of our allies. The War has shown many weak spots in our social organisation, and every citizen who has the welfare of his country at heart should study the matter so as to ascertain the causes and remedies and assist in carrying out urgently necessary reforms for the advancement, welfare, and happiness of the people. Democracy is the equality of the educated and uneducated, and the good and bad alike, and as all modern systems of govern- ment must ultimately come to the collective vote of the individual, Right, Justice, and Freedom will depend on the intelligence and judgment of the individual and everything that can elevate the mind and body will advance the State to these ideals, and the only means to attain these ends is a sound education not of the few but of the many, for by knowledge the Nation gains power while the uneducated is a danger to himself and a menace to the com- munity. Europe will always be the dominating factor in Peace and War, and it is to Europe we must look for the settlement of prob- lems between the Nations. Europe is by far the most complex of all the great divisions of the Earth, with about fifteen different languages, innumerable and increasing types and forms of re- ligion, -without any prospect of assimilation or agreement, and systems of government and politics still more numerous and unstable. Surely we see in these more than enough elements for misunderstanding and trouble, but when we go outside Europe we are faced with further problems in the various forms of language, religion, and polities. With all these perplexing differences we naturally look for some factor common to all nations, by which a 5 structure of Justice and Freedom can be built up, and of all the factors in human affairs Science is the only one which is universal and common to them all; it cannot be altered by language, religion, or politics, although it has often been crippled by each. As to Australia, her isolaled position from all other continents resulted in a unique and slower course of evolution in her flora and fauna, and politically she also differs from other continents in having practically one race of people, one language, and the oceans as her frontiers; she can thus develop her destiny untram- melled by the many complex problems and close competition of other nations separated, as in Fm rope, by a five-wire fence, a river, or a narrow strip of neutral ground. Many hold and just experiments in social and industrial organisations have originated in Australia, hut the question whether the absence of the stimulus of close contact with the ideas and pro- gress of oilier countries will he an advantage or otherwise time alone will answer. in the Great War, science has been used to the utmost extent by all the participants, and now with the prospect of Peace, surely science will be called upon to assist more than it lias ever been before, in the work of reconstruction of national life and industry. We cannot go backward, nor can many of the unhappy and un- just conditions of living be allowed to continue. If the conditions of human affairs be made better as the result of the War, the sacrifices involved will not have been in vain. T refer to science in its widest sense, as the correlation of knowledge, for to know a truth in relation to another truth is to know it scientifically. It would be impossible in a short address to do more than take a hurried glance at the history of scientific thought which has attracted mankind from the earliest ages, and realise how it has been encouraged and suppressed at various periods of history. Of all the sciences, astronomy has always appealed to mankind and has been studied from the earliest times. From time imme- morial the recurring alternation of day and night and the seasons have appealed to men’s thoughts, and attempts have been made to understand and explain these workings of nature. Phen- omena of non-recurring or isolated events, such as thunderstorms or earthquakes, have generally in the past, and I fear sometimes in the present day, been attributed to what is called the super- natural, which T presume meant that there was no explanation available. The motions of the Heavenly bodies were observed and studied in ancient times by the Chaldeans, Chinese, Arabs, Egyp- tians, and Greeks, and it is from the Chaldeans and Arabs that many of the names used in astronomy are derived, but it is to the Greeks that great advances in astronomy and other sciences 6 are due, and if the Greek astronomers had possessed the telescope and the pendulum, they would probably have brought this science to a point not actually reached till the time of Sir Isaac Newton. When we think of the theories and attempts to explain natural occurrences without the instruments of precision or the vast accumulation of scientific data which we now possess, we can only express admiration for thoughts and theories of ancient in- quirers. 1 might allude to the very interesting and ingenious ex- planation made by the ancient Egyptians of the alternation of day and night. It was assumed that the earth, presumably Hat, was cov- ered by a great dome or arch, and day was caused by the sun travel- ling along the inner side of the dome from sunrise to sunset; while from sunset to sunrise the sun on its return journey crossed the outside of the dome, where it was hkhh n from the earth, and the stars were blit holes in the dome through which the sunlight could be seen. This primary idea was not accepted by the Greek astronomers, as the theory of Hipparchus and Ptolemy (about 160 B.C.) assumed that the sun and other bodies revolved round the earth as a centre. This explanation gave way to the theory pro- pounded by Copernicus about 1500 A.D., which is the theory now accepted by science. So with other sciences the great doctrine of the conserva- tion of energy and matter has become one of the basic principles of physics and chemistry, and the latter science has made extra- ordinary advances during the last few decades, and was one of the most important factors in the War, and made use of by both sides. The newer 1 science of biology is scarcely less important, and has revealed some of the most beautiful operations in nature. For instance, for long it was thought that trees and plants de- rived the material for their structure from the soil on which they grew, until the biologist showed that about 95 per cent, of the tree is derived, not from the soil but from the air and water, through the agency of sunlight acting on that wonderful material chlorophyll, the green substance of the leaves separating the car- bon from the carbonic acid gas in the air and the hydrogen from the water, and these two elements combining to form the wood structure and returning the oxygen to the air, a process which is reversed when we burn up the timber. The sister science of bac- teriology has shown how great is the part played by bacteria both for good and evil from a human point of view. The ruins of the great empires of Babylonia and Assyria testify to the ability of the engineers and builders. Also Persia, India, China, and Egypt can show that works of great magnitude were achieved which would even in modern times he considered formidable, with all our appliances and resources. Indeed, these ruins show the careful thought and accurate scientific knowledge that were brought to bear on these ancient works.. 7 It is curious to note that most of the mighty nations of antiquity began and flourished in more or less rainless regions, and thus made the study of hydraulics a necessity, and engineering science was directed to water conservation and irrigation, and the remains of these works show what a high degree of efficiency had been attained. In the ancient world, science reached her greatest height when Greece was at the zenith of her renown; and her temples, monu- ments and works stand out for all time as a tribute to her great- ness in science and art, and to her philosophy and freedom of thought. Rome never rose to the same high position in science and philosophy as her elder rival, Athens. Indeed, Rome was, perhaps, more utilitarian; the great works of the Roman engi- neers and architects stand to-day, monuments to their ability and skill. Of this classic period T might mention a few of the great thinkers and workers in science such as Euclid, Hipparchus, Ptolemy, Archimedes, Hero, and Democritus, names which prove that the prosperity and renown of any nation are intimately asso- ciated with scientific knowledge and its application. With the rise of Christianity and the descent of the Northern Barbarians upon Rome and Greece, civilisation and science suffered an eclipse — and over Europe spread a dense pall of scien- tific ignorance during the dark ages from the 4th century, when Hypatia, a celebrated woman philosopher and mathematician, was murdered by a fanatic mob at Alexandria — to the time of Galileo' in the 17th century. But even in the darkest hour science never lacked its devotees, and the sacred torch of science was kept alight by the great Califs of Bagdad and other cities of Arabia,, who encouraged science and especially astronomy. The old Greek works were translated into Arabic, and the Arabian astronomers carried on the work and made many advances during the centuries of intellectual darkness in Europe. Galileo is famous not only for being one of the earliest to use the telescope, and for his experiments in dynamics, but also be- cause his teaching of the doctrine of Copernicus that the earth revolved round the sun brought him under the ban of the Inquisi- tion, which forced him, in 1633, to abjure the Copernican theory, and thus brought about the first clear-cut conflict between science and the powers of the dark ages. When we look hack at the dark ages, that long period of 1,400 years when scientific thought and experiments were banned as impious and evil, we must realise that but for this period of stagnation and oppression science and civilisation would have advanced vastly beyond the position we occupy to-day. With the progress of scientific knowledge and thought up to the first few centuries Anno Domini, many of the great inventions of modern 8 times might well have been made a thousand years ago. The ancient world, especially Greece, was close on the threshold of great dis- coveries. The steam engine, which is, I think, the most important inven- tion in the history of mankind and one of the greatest factors in civilisation, was created and operated by Hero, a Greek engineer of Alexandria as far hack as 150 B.C. This engine, called by Hero the “Aeolipile” was of a primitive rotary type, in which the pressure of steam was maintained in the boiler, and the steam, escaping under pressure from jets, caused the engine to rotate. Hero also described his air and water pumps with cylinders and pistons, and it was not until the lapse of eighteen centuries that t He steam engine with cylinders and pistons was designed by Papin and others, and steadily developed into the steam engine of to-day. The name Electricity is derived from “Elekfcron,” the Greek name for Amber— a material which, when rubbed, attracts small particles of straw, paper, etc. Thales of Militus, 600 B.C., is credited with having pointed out this property of Amber, but there does not appear to be any record of further knowledge on the subject until the 16th century, when Gilbert published a work on Magnetism and Electricity. The printing press was known to the Chinese many centuries ago, but not until the 16th century was it re-invented in Europe. I think we may fairly assume that but for the dark ages railways, steamers, electric machinery and appliances might have been invented a thousand years instead of about one hundred years ago. It is hard to realise what our present conditions would be if the sciences of astronomy, chemistry, engineering and biology and political economy and social conditions had ten centuries ot know- ledge and experience behind them. Indeed we have lost a thou- sand years of progress. When we look back on the ruins and wrecks of the civilisa- tions of Babylonia, Egypt, Greece, and Rome, we may well ask “Is our own civilisation and science secure from similar annihila- tion?” During the last hundred years the teaching of science has advanced perhaps more than in any other period of history and it has become world-wide. The same laws and facts are taught in the class rooms and laboratories in every University throughout Europe, Asia, Africa, America, and Australia. The starry heavens, the seas and mountains, the trees and flowers— sublime works of nature — are common to all mankind, and the study of these forms the language and thoughts of science. 9 There are two main factors which science teaches: one, that we must always be prepared to review our theories and doctrines in the light of new discoveries and new data, for there is no finality to scientific knowledge. The scientific beliefs of one gen- eration have frequently been abandoned by succeeding genera- tions, because their observation and data have been based on the apparent and from insufficient knowledge has failed to point the real factors. I jack of observation instruments prevented early investi- gators from analysing and proving their theories, and even in the present day doubt lias been thrown on the existing assumption that light travels through space in a straight line uneffected by gravita- tion as of the sun, and it is expected that (he solar eclipse of last month will decide this question. We are liable to come to wrong conclusions if we only observe an • occurrence from one point of view. How often do we notice when travelling fast in a railway carriage that the sparks from the engine appear- to rush past; in a nearly horizontal streak it is hard to realise that the appearance of the fiery track is due entirely to our rushing past the slowly falling sparks, whereas a person watching the passing train would notice that the sparks are slowly falling vertically to the ground. This simple illustration should teach us to consider both sides of the story before we come to a conclusion. Science teaches us that the more we know the more there is to learn, and every new discovery opens a field for further investi- gation. If 1 may be permitted to use a simile, take two circles-, one small and the other large, and take the area of each circle to represent the extent of knowledge in each case and let the cir- cumference be called the horizon of ignorance, and you will see that as the area of knowledge increases so does the horizon of ignorance increase. Adam Gowan White, says of knowledge: “Truth is nothing more than the essence of organised knowledge.” This expression grows and alters as knowledge grows and alters; it is dynamic, not static. 1 have i apidly and in a very fragmentary manner referred to some of the phases in the history of science and its influence on civilisation, but with such a vast subject it is impossible to deal with it adequately in one evening. There are one or two modern phases, however, to which I would like to allude. For some years before the War, Germany was recognised as one of the foremost, if not the foremost, nation in the encouragement of science and in the employment of scientific works in her industries. Her scientific workers had gained for her practically a world- wide monopoly, especially in aniline dyes and also in many other chemical industries, and this was largely due to their research 10 — thorough and systematic research. I think the War has made it clear to us that any manufacturer who does not utilise a highly qualified scientific staff lias no chance against the manufacturer who does. We have frequently heard the statement that science made Germany brutal. With this I do not agree. It might be true to say that Germany made science brutal, or rather that she used science in a brutal manner ; but war in itself is brutal. The difference between British and German science is that Germany has built successfully by systematically collecting and co-ordinating the scientific data and investigation of her own and other countries. Information of inventions and industries is more easily obtained from German publications than elsewhere. But British scientists have always led the way in scientific philosophy and great inventions. British science is built more on initiation, whereas German science is more encyclopaedic. No country can compare with Great Britain in the record of famous men of science, and there is no branch of science wherein British scientists do not hold a first place. In support 1 may re- mind you of a few names such as Bacon, Newton, Gilbert, Napier, Dalton, Harvey, Watt, Davey, Faraday, Joule, Young, Stevenson, Brunei, Tyndal, Maxwell, Huxley, Darwin, Lister, Herschell, Crooks and Kelvin. Coming to Australia, the value of scientific training is slowly but surely being recognised as a necessary factor in our national life if we are to bold our place in the world. The Federal Govern- ment has realised the importance of this matter by establishing an advisory council of science and industry, and 1 hope the Gov- ernment support will be continued. Our Education Department has also realised the economic value of scientific teaching and has introduced the system into many of the State schools, and the Department is to be congratu- lated on its work. Science, however, requires a sound general education as a basis, and I feel sure the time has arrived when the maximum compulsory age of school attendance should be raised from 14 to 1(> years. A girl or boy is ill equipped to start life at the immature age of 14; indeed, under modern conditions, and when we realise the great increase of general knowledge dur- ing the last 50 years that the standard of education has automatic- ally and irresistibly advanced, it will be admitted that such a child is distinctly handicapped in starting life compared with those who have been able to continue their education to a later age. The educational value of the teaching of science in the schools was recognised some years ago in Great Britain, the three main subjects being physics, chemistry, and biology. 11 Physics is always an attractive subject to a boy. It explains natural phenomena and machines in which a boy is interested and with which he is familiar, especially as there are so many experi- ments in physics which are simple and convincing and which can be performed by a hoy in his spare time. As a certain amount of mathematics is required in physics, such experiments offer a practical confirmation of many mathematical problems, which is also an advantage to the student. Chemistry has suffered more in the past than any other branch of science. In elementary teaching its educational possi- bilities have been greatly underrated. Elementary chemistry demonstrates to the boy as he proceeds from a simple example, revealing the nature of the chemical changes, and proving step by step in the process, so that the student gains a sound idea of a logical and ordered argument. Chemistry demonstrates this factor better perhaps than any other science. Biology also possesses a high educational value, as it trains the power of observation. Although many of the processes are com- plex and difficult to follow in the early stages, their study is calcu- lated to make a boy take a greater interest in life. Surely the teaching, at the impressionable school age, of the truths and logical conclusions of science must be for good and must be beneficial to the youth, for a sound training and judg- ment are two essentials in whatever path of life he follows. The modern schools and continuation classes which are de- signed to encourage education beyond the statutory age are a great advance. Great Britain during the War raised the age of com- pulsory attendance at schools under certain conditions from 14 to 16, so that Western Australia has a lead to follow. The Public Service is sadly behind in these matters. Under the Public Service regulations the age of 14 is accepted, in that a hoy of this age can apply for entry to the Service, and if he passes the qualifying examination (G) at this age he can be appointed temporarily as a messenger. When he attains the age of 16 he is appointed as a junior officer, and before IS years he has to pass a second examination, known as the “F” examination, which is more or less a test of his official attainments. His way is then clear without further educational tests to the highest appointment in the Service. As there are always many applicants from 14 to 16 years of age and as priority counts, students of the University or secondary schools are practically barred from entering the Public Service. This system is a contrast with that of the Professional division, where high educational and technical experience are necessary qualifications. No doubt with the advent of the Uni- 12 versity and secondary schools the regulations will be modified in due course, and the sooner the better so as to meet new conditions, Any discussion in connection with education would be incom- plete without a reference to our University, which was founded by Act of Parliament in 1911, and the first lectures began on 91 st March, 1913. Before considering our own University it might be interesting to go back to the 12th century and notice the difference in the origin and development of the medieval Italian and French Uni- versities. The early Italian Universities started as a guild of students desirous of increasing their own knowledge, who com- bined and contributed to the salary of the lecturers, and also pro- vided suitable accommodation. On the other hand the French Universities, such as that of Paris, originated from a Society of Masters: men well versed in Arts and Literature, who combined to give a course of instruction, and provided the necessary accom- modation and charged fees to those students attending the classes. All the older European Universities followed one or other of these systems, and as the Universities grew in power and influence they were frequently the subject of great pressure from the Govern- ment and from the Ecclesiastical bodies, and in some instances Universities were stalled in opposition. Both these systems have undergone modifications from time to time. All the older English and Scottish Universities show distinct traces of their original prototype, Oxford and Cambridge belong to the French or “Master” University type, while the Scottish Universities clearly show their Italian or “Student” University origin. Many Universities have been founded by private individuals but in almost every instance tuition fees are charged by the Uni- versity, irrespective of its origin. The University of Western Australia differs, in that it was founded and is financed, by the State, and no tuition fees are charged. Although fees are charged at other Fniversities it does not follow that the student himself has to bear the cost. There are numerous instances of public-spirited persons who have pro- vided the money for the payment of University fees. The Carnegie trust is a notable instance where the fees of a large number of students who attend the Scottish Universities are paid. When the student has completed his course, and has started his subsequent career, lie is ex r eeled to repay to the Trust the amount of the fees paid for- his tuition. The whole tendency of the present day is to remove every obstacle from the path of the student seeking knowledge at the centre of learning. 13 The preamble of the University of Western Australia Act states : — • And whereas it is desirable that provision should be made for further instruction in those practical arts and liberal studies which are needed to advance the prosperity and welfare of the people: And whereas it is desirable that special encouragement and assistance should be afforded those who may be hindered in the acquisition of sound knowledge and useful learning by lack of opportunity or means: And whereas for these purposes it is expedient to in- corporate and endow a University within the State of Western Australia. Provision is made by the Act for payment of £13,500 per annum. The enrolments for the first year (1913) numbered 184, and since then the number of students has more than doubled. The number of students is as follows :— Number of Year. Students enrolled. 1913 184 1914 182 1915 214 1916 214 1917 236 1918 270 1919 400 This involves an increase in the accommodation and in the Teaching Staff, so that an increase in the annual grant is urgently required. It is a matter of disap point merit that, with the exception of Sir Winthrop Hackett, nothing in the way of an endowment has been made to the University. No doubt when the real value of the insti- tution is better understood and appreciated the University will have many more friends and supporters. There are many persons who do not approve of a free Univer- sity, and it is said that students do not appreciate learning if it is free. I do not agree with this view. 1 cannot believe that students do not appreciate the teaching and personal care given by the Teach- ing Staff, nor that graduates think less of their degrees because the State provided the facilities for obtaining them. No doubt there are students who join without any intention of continuing and who will drop out during the terms, and such students hinder others of more serious intent. To charge fees to all students simply in order to offer some obstacle to those who have no intention of studying would be hardly just to genuine students. 14 This State is trying the new experiment of a free University, which is a great step forward in education, but with only six years of existence, four and a half of which were under more or less war conditions, l feel that the time is too short to say that the experi- ment has proved a failure. I am sure it would be a retrograde step to return to the old system of charging fees for tuition. One of the difficulties of any change or improvement in an educational system is the long time which must elapse before the real effects of a change can be understood or realised. Certainly it cannot be less than 20 years; not until the students of to-day have become factors in the life and development of the State, will the real value of University training be appreciated. The whole question of Education is undergoing a change, but it must of necessity be slow. A sound education for all is un- doubtedly the best investment of the State. The question is not,. “Can we afford free education,” but “Can we afford to do with- out it 1 ?” 15 PHYSIOGRAPHIC NOTES FROM THE UNI- VERSITY OF WESTERN AUSTRALIA. THE PHYSIOGRAPHIC ELEMENTS OF THE SWAN COASTAL PLAIN. By W. G. W oolnougHj D.Sc., F.G.S., Professor of Geology. ( Bead 13/7/ August, 1918.) The city of Perth stands upon the banks of the Swan River , here a mature stream il owing across a sandy plain some twenty miles in width. This plain has been described as the Swan Coastal Plain by Jutson in his comprehensive account of the Physiography of the State.'* The author desires to point out some details in connection with the structure to which attention was not drawn by Jutson in his more general account. On the east the plain is bounded by the scarp forming the western boundary of the Darling Peneplain.! Between the laterite-capped summit of the Darling Peneplain and the reefs of Rottnest Island, Garden Island, etc, the author believes that at least a dozen distinct physiographic elements may be recognised. (See Fig. 1.) (a.) The summit level of the Darling Peneplain. This rises to a remarkably uniform level of about 800 feet above sea level and extends almost without variation in character for at least 200 miles in a north and south direction. It is capped by lat- erite and is intersected by deep youthful river \ alleys, carved out of it since its upheaval. (h.) The edge of the Darling Peneplain is formed by a sharp escarpement, the “Darling Scarp,” due, proximately, to the under- mining of the hard laterite capping by the forces of erosion. While, as Jutson has pointed out, this feature is a fault scarp, the present edge of the plateau is not coincident with the actual fault plane, but has retreated some distance to the east of the earth-crack as a result of erosion. (c.) West of the cliff-like edge of the laterite capping is a hill slope, generally fairly steep, leading down to the edge of the plain itself. This element we may call “the Foothill Zone” On these foothills are exposed the basement rocks of the Peneplain, chiefly granites in great variety, seamed with dyke-like masses of basic and ultrabasic intrusive rocks, mostly somewhat recrystallised. From fLoc. cit., p. 42, 43, where references to previous literature are a-iven. 16 Gosnells to Mundijong, at least, there appear at intervals exposures of slaty rocks, dipping at high angles, and apparently surrounded completely by eruptive materials/ In places, also, enormous quartz reefs, or sections of one great quartz reef, are met with (Brunswick, Gosnells, etc.). Ibis exposure of relatively fresh and undecomposed basement rocks bespeaks the rapid erosion which is going on throughout the foothill zone. (d.) At several points along the outer part of the foothill zone there appears a laterite-covered shelf at a very strikingly uniform elevation of about 200 leet above sea level. Tt appears, rather ob- scurely, at Greenmount and Armadale, much more decidedly at Ridge Hill, the lower part of the Kalamunda Road, and Waroona. The ap- pearance of this laterite at all points, and its relationships at Ridge Hill and Kalamunda, seem to distinguish it from the widely-dis- tributed detrital laterite described hv Simpsonf as occurring at low levels. Much more research will have to be carried out before the existence of this shelf as a definite independent element can he claimed. Tentatively, however, we may suggest its existence and explain it as the remnants of a step-faulted portion of the plateau, let down by a subsidiary fault, immediately to the west of, and par- allel to the main Darling Range fault. For this somewhat hypothetical element 1 suggest the name “Ridge Hill Shelf/ (e.) We reach now the main “Darling’ Fault” which has been responsible for the entire structure of the region, and which separ- ates the isostatically adjusted uplift area on the east, and subsidence area on the west. The actual fault plain is not known to the author at any point, the line of junction of the ancient crystalline rocks of the plateau and of the recent accumulations of the plain being hidden by detritus. Of the existence of such a fault, however, there can be no doubt, and of its tectonic importance there can lie no question. (/.) The “Piedmont Zone” follows next in order and is of the utmost economic importance. Steep-grade, rapid streams flowing down from the youthful valleys of the plateau element bear with them the well rotted detritus derived from both granites and “green- stones.” On reaching the plains these streams have their velocity checked and are forced to deposit their sediment as flat alluvial fans or dry deltas. The streams are legion, and deposits of adjacent streams uniting at their lateral edges, build up an almost continuous, gently sloping zone of alluvial matter right along the base of the main hiil feature. Containing as it does a modicum of potash derived from the felspars of the granites, and quite a notable amount of lime ob- *Honman, C. S., The Extension of the Kelmscott Clay Deposit. Bull. Geol.

Mag 1 , n.s. rlec. v. vol. ix., p. 399-406, 1912. 17 tained from the greenstone, the soils of this piedmont zone are, rela- tively, somewhat rich in plant food. The distribution of land suit- able for citrus fruits, limited on the west by a line approximating to the South-Western railway is determined by the extent of this zone. Each alluvial fan is slightly convex in profile and its stream occupies a notch on this convex surface. This introduces a tendency to instability of location of the channel, and there are probably in- stances of streams having left the convex surface to flow into the intervening hollows. Mostly, however, the streams occupy notches on the fans, a feature which is evidenced by the occurrence of the viaducts along the railway line at the summits of the grades in many instances. ( A very good example of this is at Keys brook. ) The outer margin of the piedmont zone is lobate, and cusps of the plain run in be- tween the lobes. The width of the belt varies considerably with the magnitude of the constructive streams, but is probably only from half to one mile on the average. ( g .) The “Bandy Plain” follows the piedmont zone on the west. Into its constitution a number of sub-elements enter, whose relations vary considerably from point to point. As a whole the sandy plain is gently undulating, but quite sharp gradients are by no means infrequent. These are caused by the dominating structures of the region, namely, sand dunes of molian origin, geologically re- cent, but sufficiently old to have been fixed completely and perman- ently by the growt h of vegetation. Between these dunes there stretch low lying areas. During the extremely wet winter season the level of ground water rises to the surface in such localities, arid we have swampy areas filled with coffee-coloured peaty water. These swampy areas come to contain a moderate amount of clay substance and humus so that, when drained and cultivated, they become quite val- uable agricultural land, particularly for market gardens. The Chinamen’s gardens in the immediate vicinity of Perth are examples. Quite distinct Prom these smaller sporadic lagoons, there is a well-defined zone of large and shallow, hut more or less per- manent, lakes stretching along a north and south line between the hills on the east and the coastline on the west, including, amongst others. Lakes Jandakot, Bibra, Herdsman, Monger, etc. The origin of these lakes is under investigation and will form the subject of a further comm imi ration to the Society. Beyond the “Lake Zone” the sandhills of the plain continue to the west as they do to the east, hut they become more pronounced and individualised, probably be- cause more recent, in this western section. (//,) Forming a continuous belt facing the coast, rising into \ er\ respectable hills (Buekland ITill 207 feet), and projecting sea- wards as rocky headlands honeycombed with large and small cavi- ties, is the zone of “Coastal Limestones.” Formed by amlian action on the existing coastline, and composed largely of comminuted mar- 18 ine calcareous organisms, these rocks have been consolidated super- ficially into dense travertine (“cap-stone”) in many places by alter- nate solution and precipitation of carbonate of lime. As a result of this mode of origin concretionary structure is very wide spread. Travertine formation has been very irregular, or else solution chan- nels have been frequent, or both factors in development have been operative. As a result extraordinary “nigger-heads” and “teeth” of limestone have been formed or left amongst 1 Lie less solid sand. These are well exhibited hi the railway cuttings near the Show Ground and in the river bank near the boat-sheds at Peppermint Grove. Plant roots have formed channels for percolating water and may, perhaps, have contributed organic solvents during life or dur- ing decay, so that the segregation of calcium carbonate has been directed, in its first stages at all events, by root distribution. The structure lines so initiated have been extended and enlarged, produc- ing the arborescent rods of limestone which form so striking a fea- ture of the railway cuttings between Oottesloe Beach and North Fre- mantle. False bedding has been extensively developed during the forma- tion of those rocks and gives rise to very striking features in the topography produced by them (for example, near the Mount Lyell Chemical Works at Rocky Bay). In places [e.g, 7 North Fremantle) the superficial crust of lime- stone is sufficiently pure to be burnt for lime, while at various places in the Metropolitan area the subjacent calcareous sandstones have supplied rather inferior building stone and road metal. (k.) Next in succession we come to the actual “Shore Line” of the Indian Ocean. This is composed mostly of sandy beaches backed by actively moving sand dunes, which, in places, are encroaching very seriously upon residential and industrial areas. Extensive rocky promontories are scarcely existent, but small headlands of coastal limestone alternate with the sand beaches. A well-defined wave-cut platform of limestone is recognisable in places at a level such that it is extensively exposed at low water. The significance of this platform is being discussed in another paper by Mr. J. L. Somerville. (/.) In the immediate neighbourhood of Fremantle the shallow waters of “Gage Roads” enclosed between the shore and the Iiottnest Island to Rockingham Bay reefs constitutes another physiographic element of no mean importance. (m.) The zone of islands and reefs extending through Carnac arid Garden Island and, perhaps, Rottnest Island, forms the most westerly of the physiographic elements included within the scope of the present paper. The author has not had an opportunity of examining them personally. It is obvious, of course, that a method of subdivision like that attempted above is to some extent a matter of convenience. The various elements shade off into one another in many instances so 19 that no sharp line of demarcation can be drawn. In other cases portions of the different elements overlap and become intermingled, so that, for instance, we not infrequently find the tops of sandhills cropping up through the red soils of the piedmont zone. The deposits of the larger streams, essentially resembling those of the piedmont in composition, may extend completely across the sand plain and limestone belt to the sea, while the development of a considerable river valley introduces features which tend to mask those of the coastal plains. It is in areas between the larger streams that the consecutive elements of structure can be recognised most clearly. The best point of outlook known to the author is to be found on the crest of the hills east of Armadale. In this paper no attempt has been made to deal with the question of stream develop- ment in the area, nor to account for the well defined and extensive coastal lakes and estuaries which present so striking a feature of the topography from Hun bury to Mandnrak. These have been re- served for future study and communication to the Society. No bibli- ography has been included and few references have been given, as Jutson (loc. cit.) has provided all that is necessary in this par- ticular. o' 20 GENERALISED SECTION ACROSS THE SWAN COASTAL PLAIN. ■a.

(Bead on 10 th September , 1918, by invitation of the Council.) Although there is a certain amount of evidence which would lead to the belief that the existence of a continent to the south of the East Indies was vaguely known nearly four centuries ago, and there is definite evidence that Dutch voyagers touched at various points of the western coast of this great continent during the 17th century, no attempt was made to do anything in the way of establishing a settlement until the third decade of the nineteenth century, some 40 years after the erection of the penal colony at Botany Bay. That the Dutch made no attempt to exploit the resources of the new land was more than likely due to the fact that they were fully occupied in the task of securing wealth from their possessions in the East Indies, whilst the reason that no other nation had its attention dir- ected to the possibilities for colonisation that might exist was pos- sibly tiie secrecy with which the Dutch surrounded their discoveries. Some authority for this is to he found in the statement of the English Ambassador at the Hague in the time of Charles II. t Sir William Temple, who gave it as his opinion that: “A southern continent has long since been found out,” which he said was “as long as Java, and is marked on the maps by the name of New Holland, but to what extent the land extends either to the south, the east, or the west, we do not know.” To the same authority we are indebted for the declaration that the Dutch East India Co. ‘“have long since for- bidden, and under greatest penalties, any further attempts at dis- covering that continent, having already more trade than they can turn to account, and fearing some more populous nation of Europe might make great establishments of trade in some of these unknown regions which might ruin or impair what they have already in the This statement has been vigorously denied by the Dutch, but the fact, remains that of the voyages made by the Company little was known until the publication of the instructions issued by the Gov- ernor General of Batavia to Tasman on his second voyage in 1644. This curious document was found by Fir Joseph Banks in 1770 when turning over the old archives at Batavia, and was published by Sir Alexander Dalrymple in his Collections concerning Papua. The Dutch voyages were followed from MSS to 1818 by the English voyages of discovery and survey, notably those of Dam pier, 22 Vancouver, Flinders and King, all of which brought back to Eng- land accumulative and definite information concerning the western coast of New Holland. Even with this information, however, in its possession, the British Government took no steps towards the foun- dation of a settlement on any part of this wide area. In all likeli- hood this was owing to the unsatisfactory reports on the new terri- tory brought hack by the navigators, who, confining themselves to the more or less uninviting coast line appear to have made little or no examination of the interior, and so to have missed the more fertile districts further inland. Another contributing cause may have been the fact that, the population of the old country, depleted by the long Napoleonic Avars, had not reached that congested state which made it necessary for the Government to further the estab- lishment of new colonies as outlets for the surplus people. At the same time, private enterprise Avas scarcely likely to be attracted to the new country, as the only inducement in those days to leave the comforts of civilisation Avas the almost certain knowledge that fortunes, great in extent and rapidly gained, were to he secured bv a few years exile. All these excuses for the non-fulfilment of her destiny on the part of Great Britain appear to have, however, gone by the hoard when the suspicion entered into the minds of the British people that other nations, and more particularly the French, were contem- plating new settlements in the South seas. It is impossible to ascer- tain how those suspicions arose, as an exhaustive examination of the policy of Napoleon fails to reveal any suggestion in his mind of Aus- tralian colonisation, and although during the long years of his cap- tivity on St. Helena, Napoleon discussed very freely his projects, as well as his successes and failures, Avitli those around him, no men- tion appears ever to have been made of any project of that char- acter. That the suspicion existed in the minds of the members of the British Government there is, however, ample evidence, and this sus- picion had also communicated itself to the Directors of the East India Company one of whom, the Hon. C. F. Greville, wrote to Brown, the naturalist of the “Investigator,” in 1802, a letter in which he said: “I hope the French ships of discovery Avill not station them- selves on the coast of New Holland.” In his “Recollections, Lord Russell states that during his tenure of the Colonial Office, a member of the French Embassy called upon him and asked what portion of Australia was claimed by Great Britain, to which he replied, “the whole.” As Lord John Russell was Secretary of State for the Colonies from 1839 to 1841, it seems strange that that question should haA T e been asked at that late period, but possibly the scientific researches of French navigators at the beginning of the century may have been present in the French- man’s mind. 23 Again, the Earl of Ripon in 1833, with regard more particularly to Western Australia, said: “The present settlement at Swan River owes its origin, you may perhaps he aware, to certain false rumours which had reached the Government of the intentions of a foreign power to establish a colony on the west coast of Australia. The design was for a time given up entirely on the ground of public economy, and would not have been resumed but for the offer of a party of gentlemen to embark in an undertaking of this nature, at their own risk, upon receiving extensive grants of land, and on a certain degree of protection and assistance for a limited period being secured to them by this Government.” [It is now generally accepted that the French expeditions of the period had one of two objects in view, either the advancement of science or the discovery of the fate of La PerouseJ Having thus discussed shortly the attitude of the British mind towards French activities, let me turn more particularly to the causes which led to the colonisation of Western Australia, and which are to be found in the statement noted above made by the Earl of Ripon -Firstly, the fear of French annexation; secondly, the offer to colonise on the part of a syndicate. It is not necessary to inform you that rumours existed early in the century that Admiral Baudin contemplated a settlement at West- ern Port in 1802, and that Freycinet, in 1818, had made an exhaus- tive examination of the north-west coast. In 1823 we find that a further French expedition, eonsitsing of the “Thetis” and “Fs- perance, ' commanded by Bougainville and Du Camper, was cruising about the southern coasts, and this seems to have made General Darling, who towards the end of that year had assumed the gover- norship of New South Wales, anxious that some steps should be taken to deprive France of the chance of gaining a foothold on Aus- tralasian soil. Recognising that, in case of dispute, Great Britain would have difficulty in establishing her claim to the west coast, he wrote to the Secretary of State for the Colonies regarding the mat- ter, and said: It will not he easy to satisfy the French, if they are desirous of establishing themselves here, that there is any objection to their doing so on the west coast, and I therefore beg* to suggest that the difficulty would be removed by a commission describing the whole territory as within the Government ” (The territory of Vew South Wales, it may he mentioned, extended westward only to the 129° of F. Longitude.) On 1st March, 1826, the Secretary of State, joid Bathurst, addressed two despatches upon the subject to Gov- ernor Darling, and. at the same time, wrote a more or less private and confidential c-ommuneiation. The first of these despatches instructed .he Governor to commence immediate preparations for the forma- tion y a settlement at Western Port, using whatever means he might lniK best, hi the second despatch Darling was instructed to en- deavour to procure correct information respecting the country irn- 24 mediately adjoining Shark Bay, ostensibly for the purpose of estab- lishing a base to which convicts, reconvicted of lighter crimes at Botany Bay, might be sent and “that possession may be gained of a port which it may hereafter be found important to have retained.” In the private communication the Secretary says, “The sailing of two French ships on a voyage of discovery have (sic) led to the consid- eration how far our distant possessions in the Australian seas may be prejudiced by any designs which the French may entertain of establishing themselves in that quarter, and more especially on that part of the coast of New South \\ ales which has not as yet received anv colonists from this country. 1 allude to that line of coast which extends to the westward from the western point of Bathurst Island in 129° E. Longitude As this tract of shore is understood to he for the most part barren and devoid of all circumstances which could invite settlement, it is probable, if the French Government should entertain any serious intention of forming an establishment on that side of the continent, any island with so advantageous a port as Western Port would not be overlooked by them In giving those instructions you will observe that 1 have carefully avoided any expression winch might he construed, in the event of the instructions being hereafter referred to, as an admission of there not having been a preoecupaney by us before the French may have admitted to establish themselves there, and you will regulate your language accordingly. The establishment to be formed at Shark Bay is, as you are aware, partly for a different object, but it is equally necessary that our projects in that quarter should not be anticipated. The advice to Darling to regulate his language probably ex- plains why there was no public proclamation of any intention on the part of the Government to establish a settlement. On the 11th March a further despatch was sent to the Governor asking him also to have an examination made of the country around King George’s Sound, as it might possibly prove a better locality than Shark Bay. Tn all probability these despatches were forwarded by the same ship. At any rate, they were answered by Governor Darling on the 10th October, 1826, who stated that, in his opinion. King George’s Sound was unsuited even for a penal settlement, and that Shark Bay was even worse, but that lie would have an exam- ination made and added, “The French would, therefore, find it diffi- cult to maintain themselves at either of these places. ’’ Immediately after the receipt of the instructions, the Governor took steps to have them carried out. Three sites for occupancy were determined upon, at Raffles Bay, Western Port, and King George’s Sound, and the officers in charge of the three expeditions were con- fidentially advised “to avoid any expression of doubt as to the whole of New Holland being within this Government, any definition of it which may he supposed to exist under the designation of New South Wales being merely ideal, and intended only with a view of distin- 25 guishing the more settled part of the country. Should this explana- tion not prove satisfactory, it will be proper in that case to refer them to this Government for any further information they may require.’* They were also instructed that if a landing should have been already effected by the French, “You will, notwithstanding, land the troops agreeably to your instructions, and signify that their (the French) continuance with any view to establishing themselves or colonisation, would be considered an unjustifiable intrusion on His Britannic Majesty’s possessions.” These three expeditions, all of which numbered convicts amongst them, duly established themselves at the points mentioned, that at King George’s Sound being founded on Christmas Day, 1826, and continued until March, 1831, when the convicts were withdrawn, and the settlement brought under the then new colony at Swan River. Meanwhile, the arrival of the French corvette “L’ Astrolabe/* at Sydney, in December, 1826, after spending a month at King George’s Sound, accentuated the fear of French annexation, and in Governor Darling’s opinion made it still more necessary that some British settlement should he established on the west coast. Fortunately, the opportunity of taking the initial steps towards that end was ready to hand. A settlement had been established at Melville Island on the north coast in 1824. which had, from the com- mencement, been a failure. In consequence, the Secretary of State instructed Governor Darling to send a war ship to the island for the purpose of removing t lie settlement to some more suitable site, pre- ferably further to the east. When the despatch arrived it so hap- pened that ILM.S. “Success,” commanded by Captain Stirling, was lying in Sydney Harbour, and the Governor appears to have com- municated the wish of the British Government to Captain Stirling in an unofficial way, as the first intimation we have upon the matter is in the form of two letters from Stirling to the Governor, in the first of which, dated 8th December, 1826, it was pointed out that the north-west monsoonal rains would interfere with the removal of the settlement at Melville Island until after April, while in the second dated December 14, Stirling suggested that instead of remaining in harbour until the following April, he should employ the time in mak- ing an examination of the Swan River. In the prosecution of these considerations, he says “Certain ideas have been suggested to me by professional observation, relative to the necessity of immediately seizing a i ossession upon the western coast of this island near Swan River.” . . . He concludes his letter with this statement: “Finally, Sir, at a time when we have one French vessel of war with objects not clearly understood, and with one American vessel of war being also in this neighbourhood seeking a place for settlement, it becomes important to prevent them from occupying a position of such value, particularly as you were pleased to say that His Majesty’s Gov- ernment is desirous of not being anticipated in such views by any 26 foreign power.” On the 18th December, the Governor forwarded a despatch to l ord Bathurst, stating that he had agreed to Captain Stirling’s proposal ’‘as it is of great importance that so advantag- eous a position should not be taken possession of by the French. . . . At the same time, if the French meditated a settlement in New Hol- land, Swan River, from the accounts given of it by Captain Stirling, should not be neglected.” In pursuance of these arrangements. Captain Stirling* left Syd- ney on the 17tli January, 1827, in the “Success” for the Swan River, with the ostensible purpose of making up the French survey de- ficiencies, and of t horoughly examining all the country within a reas- onable distance of the river. He took with him Mr. Charles Fraser, who was at that time Colonial Botanist in New South Wales. The “Success” anchored off the south head of Swan River on the 6th March, 1827, and early on the morning of the 8th, Stirling proceeded to carry out the real objects of the expedition, which were “to pro- ceed, if possible, to the source of the river, to examine the banks and the depth of water, to fix upon an eligible spot for the settlement, to ascertain the products of the country, the nature of the soil, and the practicability of forming a harbour for shipping.” For the purpose of fulfilling these instructions the ship’s gig and cutter were provisioned for a fortnight and well armed, after which, under the command of Captain Stirling, they proceeded up the river. Mr. Fraser formed one of the party. No difficulties were met with until they reached the fiats above Ileirisson Islands (the site of the present Perth Causeway ) , where the water was too shallow to float the boats, which had to be unloaded and drawn across. After that the way was tolerably easy, and on the 1.3th they arrived at ‘what they deemed to be the source of the river. “At daylight on the 13th,” says Captain Stirling, “we were as usual in motion, and observed little variation in the appearance of the land as we ascended, except that the hills on the banks were higher and more frequent, and the soil upon them of a coarser des- cription. They are here composed of a red sandstone, red clay, and an oehry loam, varying between red, brown, blue, and yellow. The soil on the lowlands continued as good as ever. About an hour be- fore starting we had the misfortune to stave the cutter on a sunken tree; lead and fearnought, however, speedily effected a cure, and we continued to pursue our course amid increasing difficulties from similar obstructions, and from the decreasing width of the stream. The hills around us were high, and we ascended them with ease, but it was in vain that we sought a view of the country; we were the more disappointed because its character was evidently changing. At length, after several halts, we reached, about 11 o’clock, a spot where the river takes an eastern direction, just above a considerable creek on the left hand. We there found insurmountable obstructions to our further progress, in fact, we have reached the termination. 27 Far beyond this there was the bed of a torrent, but no longer a river, nor even a continuation of water except in a succession of distant parts. Here, then, on a high bank we pitched our tent. The rich- ness of the soil, the bright foliage of the shrubs, the majesty of the surrounding trees, the abrupt and red-coloured banks of the river occasionally seen, and the view of the blue summits of the mountains from which we were not far distant, made the scenery round this spot as beautiful as anything* of the kind I had ever witnessed. ’’ During the course of the trip two gardens were planted about 15 miles up the river, and after some trouble friendly intercourse was established with the natives. The soil along the banks was ex- examined and an abundance of fresh water found. An ascent of the hills, to which the name General Darling Range was given, was made by Mr. Fraser. The cutter then returned to the ship, leaving the gig, with Lieut. Belches in charge, to make a hurried examination of a tributary liver (the Canning), to which the French had given the name of Moreau Inlet. After her return the crew of the frigate was employed surveying the islands of Ruttnest, Bert boll et (now Carnac), and Bn ache, as well as the adjacent rocks. On Buache a garden was planted (from which probably the present name, Garden Island, was derived), and some cattle and sheep left there. The “Success” sailed for Geograplie Bay on March 21. Here Stirling remained until the 25th, when he set his course for Iving George’s Sound, which was reached on April 2. He remained at the settle- ment, which did not come up to his expectations, until two days later, w^ lie. left for Sydney, arriving in Port Jackson on the 15th of the same month, having been absent about three months. So far as their reports go, both Captain Stirling and Mr. Fraser seem to have been greatly impressed with the possibilities of the newly -exam inerl country. The latter, who had certainly greater expeiience in judging, was, if possible, the more pronounced in his good opinion, and there is no doubt that his oninion was largely relied upon when the question of colonisation was under discussion. In concluding his report upon the natural history, soil, etc., of the Swan River district, he says: ‘‘I n delivering my opinion on the whole of the lands seen on the banks of the Swan, T hesitate not in pro- nouncing it superior to any I have seen in New South Wales east- ward of the Blue Mountains, not only in its local situation, but in many existing advantages which it holds out to settlers, viz. : (ID The evident superiority of the soil. (2.) The facility with which settlers can bring their farms into a state of culture from the open state of the coun- try, the trees not averaging more than ten to the aero. (3.) The great advantage of fresh water springs of the best quality, and consequent permanent humidity of the soil— two advantages not existing eastward of the Blue Mountains. (4.) The advantage of water carriage to their own doors and the non-existence of impediments to land carriage. These favourable reports so impressed General Darling that he forwarded, on April 21st, 1827, a despatch in which he strongly ad- vised the Home Government to establish a settlement at Swan River as quickly as possible. In this despatch he points out: “As Captain Stirling’s visit to Swan River may attract attention and the report find its way into the French papers, it appears desirable, should His Majesty’s Government entertain any intention of forming a settle- ment at that place, that no time should be lost in taking the neces- sary steps.” Stirling’s report and the Governor’s despatch appear to have been conveyed to England by Stirling in person, and were forwarded by the Colonial Office to the Admiralty for an opinion in regard to the formation of a settlement at Swan River. The Secretary to the Admiralty, whilst admitting the physical advantages detailed by Captain Stirling and Mr. Fraser, was of opinion that the anticipa- tions of commercial intercourse with India were fallacious, and that it Avas questionable whether it was advisable to form a settlement on the west while so many millions of acres of rich country remained unoccupied on the eastern side. The report concludes with this statement : “No other motive, I conceive, than the political one of preventing other nations, as the French or Americans, of possessing themselves of the south-west corner of New Holland, should induce us to anticipate them; and even in the event of its falling into the hands of the one or other of these Powers, it would be a long series of years before they could give our other colonies much annoyance.” After consideration of the various reports and opinions dealing with the question, the Secretary of State for the Polonies wrote lo Governor Darling on the 2.8th January, 1828, reviewing the adverse report from the Admiralty, and concluding: “Under these circum- stances, I am of opinion that it would be inexpedient, on the score of expense, to occupy this part of the coast, and that it is unneces- sary, with a view to any urgent interest to attempt, any new settle- ment. at present in that quarter I shall not fail, however, to apprise the East India Co, of the circumstances attending the dis- covery of 'Swan River in case they should consider it advisable to make any settlements there, but 1 am not aware of any sufficient motive to induce them to embark in an undertaking of this nature.” Two days later another despatch was forwarded in which it was hinted that the same causes would probably induce the Govern- men!; to withdraw the settlement which had been formed at King George’s Sound, but that if it were ’finally decided to maintain that settlement, then, in all probability, the decision not to found a col- ony at ‘Swan River would he reviewed. This decision was conveyed by the Colonial Office to Capt. Stirling, but it does not appear to 29 have dissuaded him from continuing' his solicitations for the estab- lishment of the new colony. In May and June, 1828, the Earl of Dudley. Lord Palmerston, and Messrs, Grant and Huskisson retired from the British Cabinet and a reconstruction of Government followed, under which Sir George Murray replaced Mr. Huskisson as Secretary of State for War and the Colonies, and Messrs, R. W. Hay and Horace Twiss became Under Secretaries. This last appears to have been to some extent a personal friend of Captain Stirling, and it was probably through him that Stirling was induced once more to approach the Govern- ment with the idea of forming a colony. On the 30th July, 1828, he addressed a long letter to the Colonial Office in which he said, rater alia, “The French, under the command of Monsieur Baudin, at the beginning of this century visited that shore (that is, Western Australia) and rendered an account of it more circumstantial, but equally unfavourable, as that of the Dutch. The report which 1 had the honour to make last year to 11 is Majesty’s Government differs so widely from that of the preceding Dutch and French navigators, that it will scarcely be believed that we undertake to describe the same country. For while they report the country as sterile, forbid- ding, and inhospitable, T represent it as the land out of all that I have seen in various quarters of the world that possesses the greatest natural attractions.” He then went on to describe the character of the country, and concluded: “The above-mentioned recommendations poin*- it out as a spot so eligible for settlement that it cannot long remain unoccupied. . . . as, by its position, it commands facilities fo ‘- ( ' s/xr// Bfi/ONT I T-ft-l 'T-'| > V*' itw> » STVjrNTH 'NTH 7 ->"•-».»■ * NINTH i , *h i rr-T > TCNTH SuANr <; k h > '•»# v>^ S .. h ~~ 2) 1 . >. - -J o r if ' 1 T ’ 3 T r T r 7'i ■ ,■ f - " ' . . . , L-fr- .Ittlrt.J ■ 1 'ii Fig. 7.

In Perth the idea is evidently growing that one sells the plans of a house along with a pound of butter. Such a house requires a high hedge. In pre-Victorian days the study of the elements of architecture was included in the curriculum of education of English gentlemen, and there is no reason why it should not be a subject included in a liberal education. The study and practice of domestic architecture is also very suitable for young women of refined taste with artistic proclivities. Tn some countries women have attained a high degree of efficiency in this career, in New Zealand, Queensland, and New South Wales, and in England and America, there are female members of the archi- tectural institutes. I should be pleased to sec some girls adopt this section of the profession in Western Australia. The selfish and exploded notion that they would be intruding in a man's domain may be put to one side. DESCRIPTIVE NOTES ON PLANS. Plan A. A town house for a professional man. The bedrooms are away from the front, and the bathroom and kitchen are well placed. The side entrance is convenient. The sleeping porch is enclosed above dado with opening sashes. The inner hall is a room and not merely a passage. Every occupant, has commended this house. E.C. attached to woodshed, not shown. Plan B . — Plan by a Sydney architect, with many alterations. Suit- able for a wide frontage. Similar accommodation to “A.” The draw- ing room, hall, and dining room can be thrown into one for dancing. The back sleeping porch is approached through bedroom and bath-room. Attached E.C. Plan C . — Californian house plan altered to suit W.A. Entrance through living room, and little passage area. Dining and living room W’ith verandah give ample dancing-room. Front side verandah can be used for sleeping if required. Inside W.C. for sewerage system. An economical plan. Plan D . — A Sydney plan with central living room and bedrooms fitted with oscillating portal wall-beds which fold into well ventilated compart- ments in the daytime, and allow the rooms to be used as sewing-room, etc. All the bedroom equipment is in the dressing rooms.

THE WESTERN AUSTRALIAN CHRISTMAS TREE. NUYTSIA F LOB IB UN D A (THE CHRISTMAS TREE)— ITS STRUCTURE AND PARASITISM. By D. A. Herbert, B.Se., Economic Botanist and Plant Pathologist to the Western Australian Government. {Head 8th April , 1919.) Nuytsia floribunda, the Christmas Tree, is perhaps the most interesting member of the flora of Western Australia. It is con- fined to the South-Western division of the State, being found from the Murchison River round to Esperauee. The tree finally reaches the height of 30-35 feet, and frequently two or more trunks arise together. At Christmas time the tree is a brilliant blaze of orange flowers, which are borne on dense racemes at the ends of the branches. The immense development of flowers is all the more remarkable since so few fertile seeds develop. Many trees do not develop a single seed; others may develop a number — a very small number in comparison with the tremendous number of flowers — but very few of these are fertile. Whether fertile seeds will pro- duce mature plants is a question which will be discussed later in this paper. The failure of the tree to produce much seed may be the direct result of the large production of blossom. A great deal of stored food material is used up in the flowering period and in Nuytsia where blossom is so abundant the resources are too much depleted to provide enough food material for the maturing of the fruits. This is borne out by the condition of the mucilage in the plant before and after flowering. Before flowering the mucilage canals are full of a milky .fluid in such quantity that quite a large amount is exuded when a. root or branch is broken or cut. 1 his rapidly coagulates and blackens on exposure to air. It is very palatable to some animals, especially pigs, which root up the roots for yards if they are close to the surface. During the flowering period it decreases rapidly in amount and loses its milkiness, until at the period when the tree should be fruiting the exudation from a broken root or branch is almost nil. That this non-production of fruit is probably due to the large amount of blossom formed is also borne out by the fact that the same phenomenon occurs in the case of cultivated trees, such as th' -pple and the pear. Very frequently such trees have a tre- mendous development of blossom which results in hardly a single 73 fruit. Thinning out of the blossoms results in the production of a good yield of fruits for two reasons — firstly there are fewer fruits to be supplied with food material, and secondly a great deal of energy has been saved by the loss of the thinned-out blossoms. STRUCTURE. On digging down it is found that long underground stems run out from the Christmas Tree, sometimes for great distances (one at Como was traced for 120 yards), and giving off aerial branches having the appearance of trees at in- tervals along their length. Small plants, which tnight be taken for seedlings, are frequently found in belts of country where the Christmas Tree is common and almost invariably these are found to be suckers from this long stem. The production of suckers explains why Nuytsia is so common throughout the South-West in spite of its extremely small production of fertile seeds. The growth of the stem is peculiar both microscopically and mac rosco pica 1 ly, the second peculiarity following from I lie first. A very noticeable character is the extreme brittleness of the branches and roots, quite thick members snapping under quite a small pressure. This is not the case with the young twigs of one year’s growth. It only takes place after secondary growth, and the explanation lies in the unusual and remarkable method of secondary growth of the tree. This is similar in both stem and root, when allowance has been made for their difference in primary structure. In transverse section the young stem is quite normal. (Fig, 1. (A).) The central zone of pith is surrounded by the vas- cular bundles and these again by the cortex. In the normal dicotyledonous stem the cambium between the xylem and phloem elements divides forming xylem elements on the inner side and phloem elements on the outer side. In this way a cylinder of wood surrounded by phloem and cortex is produced. Jn the Christmas Tree the mode of growth is at first normal. There is a meristernatie layer between wood and phloem of the primary bundles and this divides until they have reached a certain size, when it loses its function and a new cambium is formed in the thin-walled cells of the inner cortex. This cambium is not con- tinuous round the stem but occurs in patches several cells in width. The cortex is divided into two fairly definite layers, the cells of the inner layer being thinner-walled and its cells smaller and more compact than those of the outer. When the new cambium is formed, several of these cells start to divide at different points round the stem forming typical cambium cells, A. Young stem. B. Old stem showing three rings of bundles. 0.

Bundle, medullary rays and mucilage canal, a xvlem; b, c, phloem; d, cells of inner cortex; e, medullary ray; ’ ' f f mucilage canal showing proteid bodies in the mucilage. 77 By repeated division phloem cells are cut off from these dividing; cells on the outer side and xvlem on the inner side (Fig. 2B). This cambium continues to grow to a certain stage when it, too, loses its power of further division and another set of new cambiums is formed out in the inner cortex in a similar manner to that described above. This is repeated continually so that successive rings of vascular bundles separated by thin-walled cortical tissue are produced (Fig. IB). Short medullary rays run between the collateral bundles but these are only the length of the xylern and rarely any longer. They do not run through the cortical tissue and connect with the medullary rays of the next ring. The walls of the medullary rays are pitted (Fig. IC). Pits are often found in the Avails of the cortical and the pith cells as Avell as in the medullary rays. Vis- cum, another member of the family, also has cortical cells Avith pitted walls through which there is protoplasmic connection be- tween adjacent cells. Mucilage canals traverse stems, roots, and leaves. They are formed by breaking down of long rows of cells. In the Awmng stem there is one canal in the pith. As the stem grows older more of these appear in the pith and in the inner cortex. When new layers of cambium are formed in the cortex these are always out- side the mucilage canals so that canals are found in the cortical tissue between the successive rows of bundles. A canal less definite in structure runs along the posterior side of the bundle of the leaf. This peculiarity m the internal structure of the stem is also responsible for the strange macroscopic appearance of the Christmas Tree The young branch is at first upright, but as it increases in thickness it takes on a doAvmvard curve until the angle becomes too steep, when it ceases growth and another branch further back takes its place and continues the growth until it, too, becomes too steeply curved, when another branch takes its place. The portion of the branch below the end and the new main branch generally dies back. This strange mode of groAvtb is responsible for the characteristic rugged appearance of Nuytsia. No such curvature is found before secondary growth has taken place and curvature is not due to a more rapid groAYth on the upper side of the stem. Branches of three or four years’ growth because of their peculiar internal structure are very easily bent under comparatively light pressure,, and the weight of the leaves and blossoms (that of the latter being very considerable) causes the gradual downward cur- vature. The secondary growth of the root is of essentially the same character as that of the stem, though differing a little because of 78 the normal structural stein, the young’ root diarch or triarch. difference of stem and root, is normal in structure (Fig. Like the young* ">) and may be h\g. i Christmas Tree, showing downward bending in the brandies. Here again the cambium between wood and phloem divides to a certain extent forming secondary elements, but soon loses its function, and new patches of cambium are developed out in the 79 inner cortex. The xylem of the elements formed from these second cambiums connects with the central xylem strands (which consist Fig. 5. Young root of Christmas Tree, a, xylem; b, phloem; c, cortex. of the primary and a certain amount of secondary wood) so that the protoxylems aie surrounded by later formed wood elements (Fig. 6). When this second ring of cambium patches has divided to a certain extent it ceases to divide and another new cambium is formed outside in the inner cortex. The bundles formed from this are not connected with the previous year’s bundles, but are separ- ated, as in the stem, by a layer of cortical tissue. All further growth in thickness after this is similar to that in the stem. The result of this method of growth is that the old root shares the stem’s characteristic of brittleness. Mucilage canals and inter- rupted medullary rays occur here as in the stem. PARASITISM. Nuytsia floribuncla is the sole representative of its genus. It is classified systematically with the Loranthaceae,* and on ac- count of this its autonomy lias long been questioned, though no definite evidence was brought forward. * See end of paper, p. 88. * 80 Fig. 6.

Dr. Diels, on finding* it growing* on barren and healthy sand-scrub, the solitary tree for miles round, considered it a far- fetched assumption that the tree would draw on the dwarf bushes at its base for nourishment, and concluded “Till some counter evidence is produced we must adhere to the autonomy of Xuytsia floribunda. ’ ’ Mr. VV. Webb, of King* George’s Sound, furnished some notes on Xuytsia floribunda in response to some questions asked by Baron von Mueller and these were published in the Victorian Field Naturalist in 1894. They are brief and may be given in full: — We can find thousands of what at first sight appear to be seedlings but on tracing the roots we always find them growing from the rootsf of parent trees, and therefore we think these supposed seedlings are nothing* more or less than suckers. Up to the present we have not been able to find the roots attached to anything; they shoot in all direc- tions and for great distances but never penetrate the soil deeply, but are always found some few inches below the surface. In this manner they may and probably do receive their sustenace from decaying vegetable matter, such as the roots of numerous species of shrubs amongst which Xuytsia usually grows. As this plant has a pretty wide range in West Australia, would it be worth while to ascertain what trees and shrubs occur in every locality where Xuytsia is found'? So tar as my memory serves me, I feel certain that a great: difference will be found in the species of plant life at different places. My own opinion is that Nuytsia is an independent tree and il requires certain conditions in the soil which can only be given to it by certain other species of plants. However, T have nothing to advance in proof of the above except that I have never found the roots attached to the roots of any other plants. Harvey (Hooker’s Journal of Botany VI., 219) thought it highly probable that there was connection between the roots but could offer no proof. Dr. Morrison apparently made some investi- gations according to a reference by Diels, but I have been unable to find a record of his work. Tn the Western Australian Year Book, 1902-1904, however, he refers to Xuytsia floribunda as “a lion- parasitic tree of the Mistletoe family. 7 ’ It would appear, there- fore, that authorities up to the present, while suspecting the para- sitic nature of the plant, have had to admit the absence of definite proof, and in some cases they have finally concluded that the Christmas Tree is independent. t The roots referred to are really stems, D.A.H. 82 Figs. 7 and 9. Figure 7. — Commencement of attack on Christmas Tree root on root of Jackson ia furcellata, showing the two fleshy arms commencing to surround the root. Figure 9. — Haustoriogcn oil a larger root (Melaleuca viminea). Part of the root has broken off, giving the haustoviogen the appearance of being the end of the small root. 83 There is nothing* in the appearance of the tree to suggest a parasitic mode of nutrition. The leaves seem quite capable of supplying* the organic food material necessary, as they are not deficient in chlorophyll, while the roots appear quite capable of supplying* the mineral constituents necessary. Roots are given off from the long* underground stems and when they are traced out they are found to branch repeatedly, finally giving* rise to long white fleshy roots up to about a quarter of an inch in diameter, and from these branch smaller white and very fragile roots. It is probably on account of the extremely fragile nature of these roots that the parasitic nature of the Christmas Tree has not actually been discovered previously. When they come into contact with another root, a fleshy outgrowth starts to develop. Two white fleshy arms start to grow round the attacked root in opposite directions from the point of contact (Fig. 7). Ultimately the two arms meet on the other side of the root and fuse so that an unbroken fleshy ring encircles the host (Figs. 8 and 9). Fig. 8. Haustoriogen on young* root of Hibbertia hypericoides. On the inner side of this fleshy ring, at the points of contact, arise the haustoria or suckers, so that it may for convenience be* called the haustoriogen (Fig. 10). The haustoria are formed on the inner side of the fleshy arms before the ring is complete. The- haustoriogen in section is found to contain a very small vascular bundle, which goes right round; but the greater part of it is com- posed of simple parenchymatous tissue. The haustoria are small tongue-like masses of parenchymatous tissue, and when they pierce 84 the cortex of the host plant they appear to derive all food materials they obtain from it by simple osmosis. There is no fusion of the cells of host and parasite. The hailstorm never go in as far as the wood. The wood is the channel of transference of water containing the organic constituents of plant life and the cortex and hast the means of transference of elaborated nitro- genous and noil-nitrogenous organic food materials. The conclu- sion is that the main object of the parasitism of Nuytsia is to obtain an additional supply of organic materials, including* nitro- genous substances. Fig. 10.

Tn contrast to this is Nuytsia *s close relation, Loranthus the Mistletoe. Here we have a plant parasitic for water and salts and quite well able to provide all the organic food materials it needs. 85 In this ease there is vascular connection between host and parasite. It has been said that the Mistletoe may be more symbiotic than parasitic when it is on deciduous trees because it is evergreen and assimilates carbon dioxide in the winter when the host tree is leafless. The greatly decreased fruit crop in attacked apple trees proves that any symbiosis is greatly outweighed by the parasitism of the mistletoe. A more complete state of parasitism is shown by Cassytha, the Bush Dodder, which is common throughout Aus- tralia. This is a twining plant with green leafless stems. From the point of contact of its stem with the host arise haustoria. Here again there is vascular connection between host and parasite, the woods and phloems of each uniting. Cassytha is parasitic for both organic food materials and transpiration water containing inorganic salts. Both the Mistletoe and Bush Dodder are aerial parasites. The natural order If hinanthaceae is notorious for the number of root parasites amongst its members. These, like Nuyt- sia, appear to have quite enough leaves to supply all the organic material necessary, but nevertheless need root connection to en- able them to reach maturity. Their root system connects with that of the host root by means of disc-shaped haustoria. The fleshy ring giving rise to haustoria, as found in the Christmas Tree, is unique. The seeds of Orobanche, the Broomrape, another exotic root parasite, will only germinate when in contact with the roots of a host plant. This is certainly not the case with Nuytsia, the seeds of which will germinate out of contact with any host root. Seedlings are very rare and generally die off young. The survivors owe their success to having obtained connection with a host root early, while early death is often due to the failure of the root to find a host and the failure of the leaves to provide all the organic food materials necessary. One seedling at Mount Lawlev was found to be drawing on the stem of the couch grass (Cynodon dad y Ion). This is interesting because it goes to show that the parasitic attacks of Nuytsia are not limited to roots. Seedlings may readily be distinguished from suckers by their stems, leaves, and rate of growth. The sucker appears above the ground as a stem about a quarter of an inch thick and grows rapidly so that in a year it is about four (4) feet high. Its pale leaves are few and sparsely scattered. A seedling, on the other hand, has a much thinner stem more closely beset with leaves, which are a brighter green than those of the sucker. One would expect the seedling to have more leaves and for these to contain more chlorophyll because it is more dependent on its own resources than is the sucker which has the reserve food material of the parent underground stem to draw on. The growth of the seedling is also much slower, a year-old seedling being several indies only in height and this is attributable to the same cause. Numerous 86 attempts to raise seedlings of the Christmas Tree have been made but up to the present all have failed. The nature of the para- sitism of the tree suggests a method of raising it successfully the planting of the seed in a spot where its roots when formed will have easy access to the young roots of a plant which has been proved to be a host. The haustoriogen is not the end of tin 1 Christmas Tree Toot. It is a lateral growth. The root continues to push its way through the soil to look for fresh victims. If it comes into contact with a large root it may run along the large host giving rise to a number of these parasitic outgrowths. Where the Moshv ring is developed round a root it grows in size but not in internal diameter, so that as the host root itself grows the haustoriogen acts as a ligature and gradually strangles it. It is a common thing to ujid a host root ending abruptly in the Meshy haustoriogen of the Christmas Tree, because the lower part, being strangled and starved, has died and rotted away. Sometimes a root attempts to word oil the attacks of the Nuytsia root by the development of cork and in some cases is successful in preventing the entry of the haustoria. If, however, the root is a small one, the haustoriogen ring may be formed just the same even though the haustoriil cannot gain en- trance, and the root is strangled by the ligature m time. In its choice of hosts Nuytsia is very cosmopolitan. It attacks herbs, shrubs, and trees impartially. Exotics and natives, annuals, biennials and perennials, monocotyledons and dicotyledons are treated alike. I have found it attacking geraniums, roses, carrots, broad beans, black nightshade, sorrel (Rumex acetosella), couch grass, the so-called tree lucerne (Cytisus prolifera var. alba), vines, oranges, IJibbertia hyperieoides, Banksia attenuata, Banksia Menziesii, Stirlingia lati folia, Melaleuca huegelii, Melaleuca viminea, Conostephium pendulum, Jaeksonia furcellata, Calythrix Mavescens, and Acacia pulchella. Further search will probably reveal it on a great many more species. Sometimes in its search- ings for a host the Christmas Tree roof comes into contact with another Christmas Tree root and attacks it in the same way that it would an ordinary root, but this is rare. It is analagous with the self-attack frequently noticed in such climbing parasites as Cassytha, the Bush Dodder, which nearly always recoils on and parasitises itself at some point or other. Very often the attack of the Christmas Tree is so strenuous that the host plant is starved and killed, in which case the fragile root which has given rise to the haustoriogen shrivels away, leaving: the Meshy haustoriogen attached to the dead host root with hardly any sign of ever having had any connection, it looks at first sight like a fungal body, but a section shows its true nature by revealing the vascular tissue and the haustoria. 87 The haustoriogens are formed along the whole length of the underground stems and this accounts for their long life in the soil when the aerial parts have been removed. They can obtain all the organic and inorganic food materials they need without assistance of aerial shoots. Sometimes this underground stem can be traced along by the line of dead, dying, and weakened plants. In other cases the attack seems to cause the host plants very little inconvenience. The number of the roots affected is, of course, the deciding factor as to whether the plant will suffer or not. Some- times nearly every root is surrounded by the haustoriogens of Xuytsia. At Como this is the ease with banksias, ti-trees (Mela- leuca viminea), and numerous other plants, both shrubs and herbs, many of which have been killed. Fig. 11. Carrots attacked by the haustoriogen of Nuytsia. A, appearance of attacked carrot. B, vertical section of same showing ligature effect of haustoriogen. li, the haustorio- gen. The rapidity of growth of the haustoriogen was shown in the case of the attack on some carrots at Como. These when only half-grown started to die off and on digging down it was found that the roots were surrounded by well-developed haustoriogens over half an inch in diameter (Fig. 11). The rapidity of develop- 88 ment of these coupled with the large number produced along the length of the underground stems shows that Nuytsia is able to obtain a large amount of food materials from annuals and other small plants when growing as the solitary tree in a pasture. Dr. Diels'* is inclined to regard Nuytsia as being distinct from the Lorantlmcea* and rather belonging to the common family from which both the Loranthacere and Proteace?e have sprung. He summarises his objections as follows: — It (Nuytsia) cannot truly be said to belong to the real Lorantliacea? because of its fruit, and its habits remind one me > re o f the ( J re v i 1 1 eoidflp . The difference of fruit does not seem sufficient reason for separat- ing it from the family to which it is assigned, greater differences of fruit being shown in other families and which are regarded as generic and not ordinal. The flower is six-partite (the typical Proteacae have four (4) perianth segments), and is that of a Loranthus; in fact Labillardiere called the tree Loranthus floribundus. With regard to habit, this is typically Loranthaeeous in many points. Parasitism is characteristic of the family, and the dis- covery of (his adds another link between Nuytsia and the other members. The leaves are very similar in their form and fleshiness, and the twigs of the < 1 1 list mas Tree are very similar to that of Loranthus celastroides in appearance. The underground stem may be compared with a similar struc- ture in the mistletoe. The l)est investigated species of mistletoe is Y is cum album, a European plant. The seeds germinate on a host plant; a sucker penetrates into the cortical tissues and bast and then stops. Subsequent growth of the branch results in the embedding of this sucker in the later-formed wood so that it ap- pears to have pierced the wood. Lateral roots are given off and run along the cortex in both directions. At intervals along this cortical root arise aerial shoots; from the other side more sinkers go in as far as the wood, and further growth results in their being imbedded in the host wood also. This cortical root is analagous with the long underground stem of Nuytsia and shows similarity in habit of the two plants, when allowance has been made for the fact that Nuytsia is a terrestrial root parasite and that the mistle- toe is parasitic on branches only. The conclusion is, therefore, that the structure and habits of the Christmas Tree are in accord- ance with its systematic placing in the Loranthacere. * Pflanzenvelt von W.A., 1906. 89 LIGHT AND THE ETHER. By Professor A. D. Ross, M.A., D.Sc., F.R.A.S., F.R.S.E, (Bead 13th May , 1919.) The wave theory of light was advanced by Huyghens towards the close of the 17th century. It gradually superseded the emis- sion or corpuscular theory which had been held by Newton, but which was at variance with the fact that the velocity of light is greater in air than in denser media such as water and glass. The medium in which the light waves take place on HuygheiFs theory is termed the aether — a subtle iluid which permeates all space. And since the velocity of light in air is the same as that of an electromagnetic wave in air. it is concluded that light itself is an electromagnetic wave. This conclusion has been generally accepted as the result of Hertz’s experiments and Clerk-Maxwell mathematical investigations. The velocity of light has been determined in a variety of ways: — 1. From Romer’s observations of the acceleration and retardation of the times of occuiTen.ce of eclipses of Jupiter’s satellites depending upon the varying, distance of the Earth from Jupiter. *2. From Bradley’s investigation of the aberration of light — light appearing to come from a direction slightly different from the -true direction in consequence of the Earth ’s motion (the effect is strictly analogous to the phenomenon of vertically falling lain appearing to come obliquely from in front against a person moving through it). 3. From experiments by Foucault, Fizeaii, Forbes, and others on the time taken by light to travel over a measured distance not exceeding a few miles. In Bradley’s investigations of the aberration of light, it was shown that a telescope used in observing a star was always slightly inclined to the true direction of the star by an amount depending upon the ratio of the Earth’s velocity to the velocity of light. The theory assumed that the aether was at rest while the observing telescope and the contained air moved through it. As the experi- ment gave a result in harmony with those of other methods, this assumption was evidently justified. Airy, however, repeated Bradley's experiment with the telescope filled with water. Since light travels in water with only three-fourths of its velocity in air, the aberration should have been correspondingly greater. It was found, however, to be quite unaltered. Apparently, then, air moves freely through the aether, but water drags the aether along, tresnel made a mathematical investigation of this aether drift, and his resulting formula was afterwards verified by an ingenious 90 experiment due to Fizeau, in which two rays of light were sent along the same path , one with and one against a stream of water, that is, one with and one against the resulting aether drift. If 1' is the speed at which a swimmer travels through the water of a river flowing at velocity v, then the swimmer will he able to travel up, down, and straight across the river at speeds which are respectively ( V — v), (F 4- v) t and \/( V 2 — v 2 ). Hence if the river is of width s , the time T ± taken to swim across and back is 2s/ v' (F 2 — #1, and the time T 2 to swim distance s up or down the river and back is2Fs/ (F 2 — v 2 ). That is, we have T t : T x : : F : v ( F 2 - f). But F is greater than y (F 2 v 2 ) for all possible values of F and r, and thus the time for a certain journey up arid down stream is always greater than for the same length of journey across stream. For example, a person who swims 2 miles per hour will take less than 3 mins. 28 set's, to cross and re-cross a river four chains wide (lowing at one mile per hour. He will, however, take 4 mins, to do the same length of double journey up and down the river. Now, as the Earth is moving relatively to the Sun, and the Sun relatively to other members of the sidereal universe, our Earth is evidently in general travelling through the aether, or, the aether has a drift relative to the Earth. And for light travelling at velocity F through an aether drift of magnitude v, the time for the double journey along the line of aether drift must be greater than the time for a path of equal length at right angles to, that is athwart, the aether drift. Michelson and Morley attempted to test this by experiment. They sent a ray of light along a certain path and reflected it hack to the point from which it set out. Another ray was sent an equal distance along a path at right angles, and any minute difference in the times taken by the two rays to return could be easily ascertained by a delicate interfer- ence test. The two rays were found to take precisely the same time. As this was contrary to theory, it was clear that the path which was across the aether drift must really have been longer than the path which lay along the aether drift. Now these paths were along rigid iron arms attached to a vertical stand floating in mercury. The apparatus could thus be rotated through a right angle so that the path which formerly was along the aether drift was now across it, and vice versa. But on repeating the experi- ment in this new position there was found again to be no differ- ence in the times taken by the rays to cover the two paths. Only one conclusion appears possible — the rigid arms altered in length, shortening when turned into the direction of the aether drift and lengthening when turned at right angles to it ! Remarkable as is this conclusion, there is no escape from it, and scientists now accept the fact that our standards of length — the standard yard 91 kept in London and Borda’s standard metre — change in length from time to time as the Earth changes its direction of motion through space and through the aether, or as these bars are turned about in the laboratories in which they are kept. We have no means of measuring our speed relative to the aether. For all we know to the contrary our Earth may at the present instant have a speed of, say, 190,000 miles per second relative to the aether. If it has this velocity, then a man who is 5ft. Sin. high when he stands up at right angles to this relative motion will be only 4ft. 9in. in height when he lies in the direction of the motion. We could not tell this difference bv the eye, because the retina of our eye would have undergone a similar contraction in the same direc- tion and the image of the 4ft. him man would cover the same pro- portion of the retina in that direction as the image of the 5ft. Sin. man would cover in the other direction. We fail to observe this actual change which takes place in the dimensions of what we call rigid bodies, not because it is possibly small (it may be great as a matter of fact), but because it is of such a character as to baffle all ordinary tests, although it is revealed indirectly by such peculiarly applied tests as the Micbelson-Morley experiment. The change will not appear just so difficult for us to admit when we remember that in all probability the forces of cohesion which bind together a rigid body are of the nature of electrical forces and thus act through the aether with its drift relative to the rigid body. We commonly speak of space as having three dimensions, the directions which we popularly term up-and-down, to-and-fro, right-and-left. We can, however, imagine a flat or two-dimensional universe inhabited by flat beings who would fail to realise what was meant by the third dimension of up-and-down. And mathematicians find it just as easy to make calculations for four dimensions as for only three. It is possible for us, therefore, to imagine a model (we cannot actually construct it) which would introduce a fourth dimension, in a two-dimensional diagram we can show in a graph how the lengths and widths of rectangles of the same shape as this page are connected. In a three-dimensional model we could show how the lengths, breadths, and thicknesses of books of similar shape to this volume are connected. And in a four-dimensional model we could show in the same way how the lengths, breadths, and thicknesses of the volumes of Proceedings of this Society had varied at different times. The mathematician can, therefore, picture a model in which are indicated by distances in four directions, mutually at right angles, what we may call length, breadth, height, and (say) time. But owing to the curva- ture of the surface of our spherical Earth, the direction which we call in Perth purely height is a direction in space which is equiva- lent partly to height and partly to (say) breadth in Sydney, and equivalent partly to height and partly to (say) length in Roe- 92 bourne.* Now Minkowski has used the fourth dimension of the nature of time as being of the same essential character as the others, and so while what we happen to regard as purely height- in Perth may be regarded as purely breadth in Cape Colony, it might be regarded as of the nature of time in some other world possessing a velocity different from that of our Earth, The four- dimensional construction is very convenient as connecting together what we term position (or space) and time, so that a graph in it gives the whole history of progress of a particle in our universe, Avhat we term the “world-line" of the particle. This four- dimensional world is spoken of as Minkowski’s space-time world, and we gather from it that it is impossible to obtain an absolute separation into space and into time, but only a relative separation made to suit the particular observer. In Minkowski’s own words, ‘‘Henceforth space and time in themselves vanish into shadows, and only a kind of union of the two preserves an independent ex- istence.” This idea is referred to as the principle of relativity, and we picture the aether as a four-dimensional continuum filling uniformly Minkowski’s space-time world. In short the position is this, that just as we have regarded such properties as the colour and scent of a rose as dependent on the acuteness and accuracy of the observer's, senses of sight and smell, so we must regard all ideas of form, position and time as purely relative and as varying for observers on different worlds having different motions relative to the aether. Time is no more absolute than our ideas of taste, touch, smell, colour and sound. Ail observation consists in the recording of coincidences. For example, in measuring the size of a microscopic object we note the coincidence of the ends of the object with two lines on two scale divisions in a micrometer eyepiece. Hence as the world-line of a particle gives its full history, observations are merely the dis- covery of intersections of these woi ld-lines, and we know of the action of a force on a particle by the deflection produced in the world-line of the particle. When there is no external action, the world-line runs straight. The gravitational influence of a particle throughout its neighbourhood, which leads to it affecting other particles and deviating their world- lilies, has been accounted for on a theory which, while it in no way explains the cause of gravita- tion, brings that action for the first time under the same rationale as other forces. It is assumed that the gravitational held sur- rounding a particle is equivalent to a strain or distortion of that portion of Minkowski’s space-time world, and that the orbit due to gravitational action of a second particle about the first is a path * In mathematical language, a. vector which is parallel to the vertical axis OZ for Perth, has ooinpommt'-i along the vertical axis OZ and the horizontal axis OY at Sydney, and components along the axes OZ and OX for Roehourne. through the distorted medium which would be straight if the dis- tortion were removed. Einstein has found that on this theory a modification is necessary in Newton’s law of gravitation. One form of Newton’s law is that expressed in Laplace’s potential function, but this form cannot be applied to such a force as centri- fugal force. To get uniformity of treatment of all varieties of force a modification is needed of the gravitational law from the statement as originally given by Newton. Einstein lias put for- ward a modified law which is indistinguishable from Newton’s law in its effects in all but a few crucial tests: that is to say, the modification has not upset in the slightest any of our customary deductions from the old form of the law of gravitation. On the other hand, using the old form of the law the motion of that point of the planet Mercury’s elliptical orbit round the Sun which lies nearest to the Sun was calculated to undergo a movement of 8 minutes 52 seconds of arc per century. Observation, however, showed the movement to be at the rate of 9 minutes 34 seconds, and Einstein’s modification of the gravitational law has altered the calculated value to 9 minutes 35 seconds. Briefly put, Ein- stein’s theory has not upset one of the innumerable cases where the old law was in agreement with fact; it lias brought agreement in one ease (that of Mercury) where grave discrepancy existed, and in at least one case it has brought closer agreement than could previously he obtained. The forthcoming solar eclipse of 29th May, 1919, will afford an occasion for further testing Kinslein's theory, The Sun during totality will he in the constellation Taurus, and if photographed will he obtained surrounded hv certain stars to the north of the Hyades group. Now on Einstein’s theory light has not only inertia but has weight, that is to say, is subject to gravitational attraction. Accordingly, rays of light coming from stars A and / > (see dia- gram) will he deviated at I y and (/ so that they appear to come from stars situated at A/ and />'. These stars will therefore appear to he not merely a solar diameter PQ apart, hut at a rather greater separation P\)', and stars at B and C, which would otherwise be occulted by the intervening Sun will he visible at the Sun’s limb. On Einstein’s theory a distortion of 175 secs, of arc would he ex- pected from stars such as 4 or I). If no distortion is recorded we shall have the strange result of light possessing mass hut not weight, while a distortion of say 0*8 seconds would upset Ein- stein’s theory hut would show that light was subject to gravity Davidson and Cortie will observe the eclipse from Sobral in Brazil, while Cottingham and Eddington will be stationed on Principe Island off West Africa. The probable meteorological conditions are not too favourable, and at the best, some time will elapse before the photographic plates have been fully measured and compared with others of the same stars taken when the sun lias moved away 94 from the group. The results will be awaited with great interest by all scientists. o [Note added 9th September, 1919. — Reports to hand indicate that the eclipse was observed under fairly favourable conditions. The astronomers are, however, waiting on to obtain photographs of the same stars after the sun has moved away from these stars. By thus having the two sets of photographs taken with the same instruments in the same positions, possible instrumental errors will be reduced to the lowest minimum.] [Note added 17th January, 1920. — At the joint meeting of the Royal and Royal Astronomical Societies held in London on 6th Nov- ember, 1919, the Astronomer-Royal (Sir Frank W. Dyson) an- nounced that the eclipse observations supported Professor Einstein’s hypothesis. One of the Sobral cameras and that used at Principe —both of which produced sharp photographs — gave about l.S seconds of arc as the distortion of rays of light at the sun’s edge. The second Sobral camera, despite its unsatisfactory performance, indicated a distortion greater than 0.8 seconds. The only other practical tesl of Einstein’s theory which has been suggested, but not yet confirmed, is a displacement of spectral lines towards the red in the spectrum of a luminous body of great gravitative power.] 95 HISINGERITE. By Edward S. Simpson, D.Sc., B.E., F.C.S. Two hydrous silicates of ferric iron are known in nature — Non- tronite and Hisingerite. Of these, the former has been recorded from many different parts of the State including' Weston i a,* but the latter, which is a much less common mineral, has not previously been observed. In fact, Anderson’s Bibliography of Australian Mineralogy shows that up till 1916, at least, it had not been recorded from any part of the Commonwealth. Recently, through the courtesy of H. G. Stokes, Esq., of Wes- tonia, and A. Montgomery, Esq., State Mining Engineer, I have re- ceived specimens of hisingerite from that centre. Mr. N. S. Stuckey, Mine Manager, says that the chief occurence is at the 740ft. level of the Edna May Deeps Gold Mine along a joint plane cutting the quartz reef at right angles to its strike. The upper water level is at a depth of only 75ft. and although the main rock masses (granodior- ite gneiss and amphibolite) arc quite tin weathered at 740ft., distinct evidences of weathering are apparent along this joint plane. The occurrence of hisingerite considerably below the surface at a posi- tion of incipient weathering coincides with the occurrence of non- tronite prevailing throughout the Western Australian Goldfields. The mineral at the 740ft. level is found in small masses and lenses associated with vein quartz, siderite, a little pvrite, and some indefinite products of rock weathering, possibly including saponite. The creamy white siderite is found not only in small masses in con- tact with the hisingerite but also, to a slight extent, scattered in granules through il. Two other small specimens from the 676ft. level of the same mine show small crusts of hisingerite and siderite: in one case coating massive pyrrhotite, in the other coating massive and crystallised marcasite with quartz. It is possible, therefore, that the silicate is a replacement of the carbonate, dilute sulphuric acid from the oxidation of the sulphide serving to upset the equilibrium originally prevailing. No evidence is available on which to form a definite explanation of the origin of the hisingerite. Tentatively 1 would suggest — 2FeCO ;r + 0 + 2(RiO.,.3H,0) - (Fe.A-2Sif).,-2H.,0 4- 2H O) + 2HCO,. In this reaction dilute sulphuric acid acts as a catalyst, the pre- cipitation taking place in an almost neutral solution. The mineral is typical in appearance. It is apparently amor- phous, f dense and structureless, with a conchoida! fracture and res- * E. S. SimpsQn : The Minerals of Westonfa. G.S.W.A.

It is opaque (1mm.) with a brownish black colour. Under the microscope the fine powder is translucent and reddish- brown in colour. Most of the fragments are isotropic, but some are strongly hirefringent, indicating the association of a small amount of cryptocrystalline matter with a colloid. The masses are very brittle and are penetrated in every direction by minute cracks, pro- bably shrinkage cracks due to dehydration. The density given by Dana is 2.5 to 3.0, but a careful determination of the density of the Westonia mineral gave for four small (2 to tom.) fragments, 2.26, 2.26, 2.27, 2.28 : the mean being 2.27. These determinations were made by diluting methylene iodide, using quartz (2.65), selenite (2.32) and opal (2.10) as indicators. The chemical composition sheds light on this low density. Some apparently almost clean mineral was taken for a rough analysis. This was found to he rapidly decomposed by cold 5E hydrochloric acid, the iron going into solution and gelatinous silicic, acid, in the form of the original mineral fragments, remaining. Treatment in this way revealed embedded granules of siderite amounting approxi- mately to five per cent, of the whole. The analytical results obtained were — Fe 2 0.. . . . . 36.8 per cent. Si0 2 . . . . 31.6 ” H 2 0 above 100° 6.0 H’O at 100° . . 21.8 ” Allowing for the siderite these are not unlike Dana’s figures,* the ratio of Si(\ to F<\,0 being approximately 2 to 1, but the water is distinctly higher, Dana's average being 21 per cent. The material analysed had been exposed to the air in the author’s laboratory for several weeks before analysis, but had not been long out of the mine, and with lapse of time might well have lost more water before reaching a condition of equilibrium in air. The extra, water, which is all lost rapidly at 100°, accounts for the low density. The chemical composition of hisingerite has not been defi- nitely settled. Hintzef does not look upon it as deserving of specific rank. He says — u Amongst the hydrous amorphous silicates there is scarcely one to be found which can be considered as a ‘'mineral,' that is, as a chemical compound or isomorphous mixture “A second section of hydrous substances consists essentially of ferric silicate, partly of lighter, mostly green, colour, such as the chloropal of Unghvar in Hungary, partly of brownish black to black colour, such as the hisingerite of Riddarhytten in Sweden: the black as a rule of greasy lustre, dense with conchoidal frac- * System of Mineralogy, 1896, Ed., p. 702. t Handbuch der Mineralogie, II., pp. 1827, 1830. 97 ture. ... In general these iron silicates are plainly still less homogenous, and on this account still more variable in composi- tion than the aluminium silicates.” Further, he quotes Knop as holding that some of these sup- posed iron silicates are only mixtures of iron hydrate with quartz or opal. Dana on the other hand,f without being able to ascribe to hisingerite a definite formula, accords it full specific rank, as also does Lacroix. § This attitude is amply justified by the closely concordant ratios existing between Fe,G :; , Si0 2 , 1LO+ and H.,0 — in specimens from widely separated localities. L. Woinschenk many years ago suggested || that nontronite is the homologue of kaolinite, its true formula being Fe.X ), • 2 S i (V 2 II, 0. Chloropal is then a mixture of nontronite with more or less opal. Reviewing the analyses and chemical and physical properties of hisingerite it appears to the author that this mineral is a dis- tinct species, the homologue of hatloysite. Its formula then is — Fe/F2Si0 2 ‘2II,0 + 2H‘o, with which further absorbed water is associated at times, e.g., in the Weston i a mineral. This formula requires 45*4 per cent.
