And, at the same time, the possibility of the metre being hereafter adopted as the unit of length, could be borne in mind on the constructional details of the standard.

3. It is urged that this standard should have two series of marks, one to be used for ordinary approximate testing, the other, a finer series, for more accurate comparison. The latter should, it is thought, be so disposed as to be subject only to minimum changes from ordinary physical causes, the temperature conditions should be arranged so as to be reasonably constant, and it should be possible to eliminate ordinary sources of error during the progress of a test. It is especially desirable that the temperature should be accurately determinable. 4. It is added also :

That, consistently with the universal practice, a complete account of the determination of this standard, including the history of the determination, of any copy of the length of the Imperial Standard used as an intermediate in laying it out, and also of every step in the process should be given.

5. That such accounts should embrace the investigation and scheme of use of each piece of apparatus employed, shewing clearly every precaution taken to ensure accuracy; that special attention should be paid to the examination of all thermometers used, and to the whole scheme of thermometry ; and that all particulars be so recorded and published as to permit of independent examination and criticism of the results obtained.

6. The publication of an account of the character indicated, for general information, will not only define the degree of precision reached in laying down the standard, it will also afford that opportunity for competent public criticism which experience has shewn to be of inestimable value in regard to such matters. It will further facilitate the examination from time to time of the constancy of the standard.

7. After such standard is laid down, it is further requested that copies be made for the use, as local standards, by the District Surveyors, and it is further asked that those officers be asked to set out on a uniform plan, an ordinary testing standard of the lower grade referred to, for the convenience of surveyors in their respective districts.

Mr. Furber, as a member of the Committee, spoke to the question, and was followed by Mr. S. Mills, who moved the adoption of the report, which was seconded by Mr. Arnheim. Messrs. Halloran, J. Miller, and E. A. Harris took part in the discussion, which was brought to a close by the chairman, who, after speaking to the question, put the motion to the meeting, when it was carried unanimously.

The proposed new scale of fees, drawn up by the Committee appointed for the purpose, was read by the hon. secretary. A considerable increase on present rates was recommended. Mr. Furber moved that the Council take steps to ensure its being placed before the proper authorities at an early date. Mr. Arnheim seconded the proposal, which was carried upon being put before the meeting.

OBITUARY.

UR readers, to whom the name of Mr. D. M. Maitland is a familiar

press of his unexpected death. Duncan Mearns Maitland was born in London in 184+, but came to this colony at an early age with his father, who will be well remembered as an old resident of the Hunter River district, where he practised as a surveyor for many years. The son, having been educated in Maitland, followed in his father's footsteps, and in January, 1865, passed the Surveyor's examination, and was licensed to survey under the Crown Lands Acts. He was at first employed as contract surveyor in the Camden district, but later in other parts of the colony, notably about Gundagai, Tumut and Adelong, where he remained till about 1877, when he was transferred to the Metropolitan District as a temporary salaried surveyor. This temporary position he did not occupy long, for his appointment to the permanent staff was shortly afterwards made, when he was attached to the Trigonometrical Survey, and subsequently to the General Survey Branch. While serving on the General Survey Staff, he was on several occasious employed as Acting Metropolitan District Surveyor, and also held the appointment of Inspecting Surveyor under the Real Property Act. In 1887 he took charge of the field supervision of the General Survey of the Colony, in place of Mr. F. B. W. Woolrych, and in September, 1889, of the Detail Surveys of Sydney and Suburbs. The work of the Detail Survey he administered until its transfer to the Department of Public Works in 1896, when he received the appointment of District Surveyor at Armidale, a position he occupied till his death.

From the above it will be seen that few surveyors have had a more varied experience than had the subject of our notice; those who knew him will be aware how well he was able to avail himself of that experience. Of a singularly clear habit of thought and much tact in the control of men, it is little wonder that his administration was unusually successful While on the staff in the Department of Lands, he was employed in most cases of difficulty in the determination of old grant boundaries, and in few cases were his findings connected with this class of work varied in the slightest degree, and his unrivalled practical professional knowledge it, no doubt, was which caused him to be so frequently chosen as a member of the Board of Examiners of Surveys. It may be safely said that no one in this colony has done more for the advantage of his fellow professionals. From the very inception of the old Survey Club, the birthplace of the present Institution of Surveyors, Mr. Maitland took an active part in all movements directed towards the improvement of the status of the surveyor, and, recognising how much that must be aided by mutual effort, he devoted much time and labour to the development of what afterwards became the Association of Surveyors and, in 1891, the Institution of Surveyors, of which we are, very properly, so proud, standing, as it does, unrivalled among the other similar bodies in the Australasian colonies. His representative position in the profession was recognised by his election for many years as President of the Institution, a position for which he was well fitted by, in addition to his other qualifications, his being a ready speaker. Held in the highest regard by all who came officially and professionally in contact with him, he was also the centre of a large circle of friends.

Some few weeks back he became unwell, but his condition was not such as to alarm his friends, it being thought that a rest from work would, with his naturally strong constitution, soon enable him to recover. With this object he obtained leave of absence, and came to Sydney. On the 19th ult., however, symptoms presented themselves which shewed his condition to be serious, and from then till his decease, on the 24th, he was almost entirely unconscious, death being caused by something of the nature of apoplexy.

The funeral took place at Rookwood on Christmas Day, and was attended by a large number of friends, as well as by his immediate relatives. His widow and daughter, as well as his two sons (Dr. H. L. and Mr. L. B. Maitland) were present, and, amongst many others, we observed Dr. Sawkins, Messrs. S. Cook, Holt, G. H. Knibbs, F.R.A.S., T.F. Furber, H. F. Madsen, W. R. Henwood, D. H. Chisholm, Watkins, A. J. Gould, E. Twynam, and W. Freeman.
