where it will be observed that A is the bar of the balance; now be directed to the secondary. The binding of B the primary compensation, and C the secondary, both C in the heat would carry the weight further from A and B being composed of compound lamina; D is the g, producing the same effect as though the weight of weight. Mr. Dent assumes, for the ground upon which the ordinary balance had been moved further along the he rests his improvement, that the lamina, as arranged rim. But now, supposing the length of C to be half the in the ordinary balance, decreases in motion the nearer it length of the lamina employed in the ordinary balance, approaches the centre; exactly the reverse of this, how-which is longer than it would be in reality, then the ever, takes place, as will be explained by the diagram, Fig, 4.

[merged small][merged small][ocr errors]

Let a represent the diameter of the balance, and b the compound rim at mean temperature, when it would be concentric with the centre of the balance d; if the segments e and ƒ are drawn by moving the centre an equal distance on each side of the centre, of the balance to and from the point g, where the lamina remains immoveable, e will represent the position of the lamina in the heat, b in the middle temperature, and ƒ in the cold. Next let equal lengths (not arcs) of the lines b, e, f, from g, be marked off by a dot on each, and these points bisected with segments drawn concentric with the centre of the balanced, from which point we lastly carry a radius | h across them. On measuring the distance along the radius between the concentric segments, it will be found that from e to b is longer than from b to f, thus showing the motion of the lamina towards the centre to be greater in the heat, and not smaller, than it is in the cold. In this diagram the motion of the lamina is greatly increased over the proportion it would bear to the other parts, if drawn to scale, in order that it might be more readily seen. From the entire motion being, as before stated, only 1-250th of an inch in the actual balance, the difference of ratio between e b and bf would of course be proportionably small. With this digression concerning the ordinary balance, the action of Mr. Dent's construction may now be explained. On a change of temperature, B would move nearly direct to and from the centre of the balance, and therefore form the primary compensation, whilst the motion of C would carry the weight concentric with the centre of the balance nearer to or farther from the point g; by which motion it is intended the secondary compensation shall be effected. This is Mr. Dent's explanation of the action, and allowing it to be correct, and also that the primary compensation might be thereby effected, attention will

bending of C in a change of temperature from 32° to 100° Fahrenheit, would move the weight 1-500th of an inch which would produce a difference in the compensation of eight seconds a day, or only one-tenth the quantity necessary. Again the first condition requires that C should not only move, but that it should accumulate in motion at the progression marked on the diagram, Fig 1. This it does not do, for C is composed of the usual laminæ, which would consequently bend at its ordinary rate, and as the motion in the lamina is too small to produce the required difference of ratio by changing its direction, the effect produced by the bending of C would therefore simply increase the primary compensation to the same extent as though the weights of the ordinary balance had been moved 1-500th of an inch along the rim. Putting these facts together, we arrive at the following conclusions-First, that the supposition concerning the common balance, upon which Mr. Dent built his improvement, is the reverse of the fact; secondly, that the effect which his construction would produce only amounts to one tenth the quantity required; and thirdly, that this small quantity does not accumulate faster than in the ordinary balance, over which the construction would not consequently possess any advantage. This method having failed to fulfil the first condition in any degree, it is unnecessary to examine it by the others. As it was considered that it would save repetition if the various methods were divided into classes, and one example selected from each, the reasoning used in the examination of Mr. Dent's plan must be understood as applying to others of the same kind.

GOLD CRUSHING AND WASHING. SIR,-In the last number of the "Journal of the Society of Arts," Mr. Phillips did me the favour to correct an error of mine and then proceeded to controvert some of the statements I had made with regard to the novelty and merit of Mr. Berdan's apparatus. I certainly am much obliged to Mr. Phillips, for whose authority I have the most sincere respect, for setting me right when I am wrong; but no practical man, it seems to me, can find any similarity between the application of heat in crushing and washing machinery, as it is applied to Mr. Berdan's machine, and the heating of a mixture or paste of mercury and powdered ore, for three or four days together. I did not say that the use of heat was new, as I had just described the Miners' Assay, in which hot water was employed; it was only on the scale and in the way in which it is applied in Mr. Berdan's machine, that I spoke of it as a novelty, and such I still consider it. Neither did I claim for Mr. Berdan the merit of inventing the plan of sending the tailings through a mass of quicksilver, as a means of saving the broken portions of that metal, but merely the peculiar mechanical contrivances by which it is effected in Mr. Berdan's separator. If Mr. Phillips had attended the meeting, and heard my remarks in describing the diagrams and models with which my paper was illustrated, he would, perhaps, have thought his letter unnecessary.

What Mr. Phillips means by "putting the public_on their guard," as applied to any remarks or acts of mine, I am as much at a loss to conjecture as he would be to explain. What I have done and said has been public and fair; and I can say as much for Mr. Berdan, who has

in this matter.

placed his machine at the disposal of all persons who felt
inclined to try it, with their own men, and their ores, and
mercury. The privilege thus freely offered has been
availed of by large numbers of mining gentlemen, and I
believe in every instance with an entire conviction that
the machine accomplished all that could be desired. The
best evidence of the sincerity of these convictions is to
be found in the very large number of machines that have
been ordered. I am at a loss to understand why Mr.
Phillips should undertake the guardianship of the public
The public generally manifests a wise
discrimination in the selection of the objects of its ap-
proval, and certainly the public of this country cannot
be accused of exhibiting an overweening fondness for
anything new. If any one has an inferior Machine to
Mr. Berdan's, the public ought not to desire that it should
succeed; if any one has invented a machine equally good,
the gold fields of the world are wide enough for both; if
any one has a Machine better than Mr. Berdan's, let him
bring it forth, and it must soon establish its character and
reap the reward it deserves.

Whether I have over-rated the value of Mr. Berdan's
machine may perhaps be seen from the Report of
Professor Ansted, in to-day's "Times" and Daily
News."
I am, Sir,

Your obedient Servant,
CHARLES F. STANSBURY.

Company to encourage the growth of strong hemp, &c in India. Attention had, however, been previously paid to this subject, but Dr. Roxburgh was subsequently employed in an experimental investigation and cultivation of various fibres which were produced in India, and which he said " may prove valuable substitutes for hemp and flax on some future day in Europe." (Vide "Trans. Society of Arts," vol. xxii., p. 389.) Of these fibres some have become extensive articles of commerce, as the_sun_of Bengal (Crotolaria juncea), the brown hemp of Bombay (Hibiscus cannabinus), and the Jute produced by different species of Conchorus, and which, though weak in fibre, is now imported here in such enormous quantities. But from its fineness, flexibility, and the facility with which it is spun, this is now used for many purposes. There is no doubt that several malvaceous plants of the East are possessed of similar properties.

Among the fibres, however, which Dr. Roxburgh submitted to examination, were some which were remarkable for their great strength, as for instance, the Caloce of Sumatra, and of which he obtained a few plants from Bencoolen, and cultivated them in the Botanic Garden at Calcutta. This he subsequently named Urtica tenacissima. He found that it could be cultivated with great ease, its stems cut four or five times in the year, and that though its fibres were separated with great difficulty, they were possessed of great strength, as well as fineness and soft. ness. He was informed by a friend at Canton that the grass-cloth of China was made from these fibres. In the

CHINESE GRASS OF CHINA.

SIR, Observing that the "Journal of the Society of Arts" publishes notices of several Indian products which are likely to be of value as articles of commerce, when their properties become more generally known, and measures are adopted for obtaining them in larger quantities, I am induced to forward this paper. For thus, I believe, the producers in the East may be induced to collect or to cultivate, to prepare, and to send to the markets of Europe a new or little-known article, and take measures for keeping up a regular supply for such manufacturers as may be the first induced to supply them. Otherwise, if a planter, more enterprising than his neighbours, is induced to send a new thing to market, it is usually pronounced to be of "no value," because "not known in the market;" and the importer is sometimes advised to send it in larger quantities for a few years, when it will have a chance of being looked at, and its true value ascertained. The planter is not often inclined to follow this advice, for his first venture has probably been knocked down at a price which does not pay his expenses. The manufacturer, on the other hand, cannot be expected to employ an article with the properties of which he is but partially acquainted, or of which he is not well assured of having, in time, a regular supply and in sufficient quantities.

Calcutta Botanic Garden to the East India House. These the Court of Directors forwarded to Messrs. Sharpe, of Mark-lane, who reported that a thread spun of this fibre bore 252 lbs., whereas the weight required to be borne by Russian hemp of the same size in Her Majesty's Dock Yards was only 82 lbs. (Vide "Illustrated Catalogue" India, p. 883.) The Society of Arts, in the year 1814, awarded a silver medal to Captain J. Cotton, of the East India Company, for the introduction of this fibre, of which the reports were so favourable for strength and other qualities.

Since that time China grass has been imported on various occasions into this country, and the fibres have been skilfully prepared by different parties, so as to have the lustre and whiteness of silk. No less than three Prize Medals were awarded at the Great Exhibition for these beautiful preparations: that is, to Messrs. Wright and Co., of London; to Messrs. Marshall, and to Messrs. Hives and Atkinson, of Leeds. I believe that a fourth was awarded for the same fibre, though under a different name: that is, to Mr. Weber, of Java, for some beautiful fibre sent by the Singapore Committee, which he called ananas, or pine apple fibre; also Linum usitatissimum and Boehmeria candicans on the same label. Some difficulties, it is understood, are experienced in spinning this China grass, but they are difficulties which have been overcome Publicity, therefore, in such a journal as that of the by the Chinese, as they prepare from it their famous Society of Arts cannot fail to give information to con-grass-cloth. Sir W. Hookerinforms us (Vide "Kew Journ. sumers in Europe, at the same time that it will impart of Botany," vol.

of Rheea fibre, which is used in Assam for making fishing Newspapers. It is remarkable how apposite are the lines and nets. The same fibre was also sent from Rurg arguments at the present time, after the lapse of nearly pore and from Singapore. The "Journal of the Ag-quarter of a century. It may help the Institutes in Horticultural Society of Calcutta" contains numerous Union to some points, when they present their petitions notices of the same fibre being found in various localities: next session for the repeal of the Stamp duty. as in Cachar, in the Shan province of Ava, in Tenasserim, Your obedient servant, as well as in Rungpore and throughout Assam, down to Siam, Singapore, and Sumatra, as well as Java; though under the different names of Rami, Calloee, Rheea, Kankkoora, Pan, &c., being everywhere employed for making the strongest fishing-lines and nets, also for cordage and for weaving both a stout and a fine kind of cloth.

It is not surprising, therefore, that so many individuals have endeavoured to draw attention to this fibre, though without success in making it known to the commercial world. A fresh impulse was given to this subject when one of the educated Chinese, introduced into Assam on account of the tea manufactory established in that valley, recognised the Rheea of Assam to be identical with the Chu-Ma, or China grass of his own country. The AgriHorticultural Society of India obtained specimens from Dr. Macgowan, settled at Ningpo, of the Chu-Ma. These Dr. Falconer, Superintendent of the Calcutta Botanic Garden, found to be "the same plant as the Boehmeria nivea of botanists, described under the name of Urtica tenacissima by Roxburgh." He further says, "The specimens from China correspond exactly with those grown in the Botanic Garden, with which I have compared them." Finally, Mr. W. Sangster, of this capital, who was well acquainted with the properties of the original China grass, obtained some specimens of the Rheea grass from Assam, and found them for all practical purposes to be the same. These were shown in the Great Exhibition of 1851.

The Right Honourable the Lords Spiritual and Temporal, of
the United Kingdom of Great Britain and Ireland, in
Parliament assembled.

The Petition of the undersigned Inhabitants of the City of
London,

HUMBLY SHEWETH,

munity is invariably commensurate with the progress of knowThat your Petitioners believe the prosperity of every comledge, and that a people trained in habits of reading and reflection will possess more resources for the creation of wealth, and the promotion of their own happiness, than it would be possible for them to command while in a state of ignorance.

That it is therefore the first duty of a state to remove every obstacle to the diffusion of knowledge, and to give the greatest facilities for the circulation of all known facts, and the free discussion of all opinions.

That your petitioners have seen with regret that the duties have all the pernicious effects of TAXES ON KNOWLEDGE, and now levied upon newspapers, advertisements, paper, and books, tend directly to check, and limit the spread of information among the people.

That the duty on newspapers in particular produces the following evil results :

1. It places beyond the reach of the poor man that kind of information which is the most calculated to interest his mind, and rouse its dormant powers into activity, namely that which is emphatically news, and relates to the stirring incidents of the day.

2. It excludes him from all knowledge of the proceedings of the legislature, and of the laws which he is called upon to obey. 3. It deprives him of the means of learning how those laws are administered, and of profiting by the example of those who may incur legal penalties; the only reports of the proceedings of the courts of law, and of the police-offices, being given in the newspapers.

4. It keeps him in ignorance of the various relations of society, the duties of citizens, the best markets for labour, the means of bettering his condition, and of an immense variety of miscellaneous intelligence, for which a newspaper is the only cfficient channel of general communication.

5. It exposes him to the influence of cheap and inflammatory publications, which it has been found the law cannot put down, while journals of a better class, which would counteract the evil, are to him rendered inaccessible.

Though Major Jenkins was the first to call attention to the Rheea grass of Assam. Major Hannay has most perseveringly inquired into the culture and preparation of this fibre, so as to bring it into notice as a commercial article, and has for this purpose forwarded, in conjunction with Captain Dalton, ten bales of the cultivated and five of the wild Rheaa fibre, to the Indian Government. These have arrived at the India House, and specimens are sent to the Society of Arts, for the inspection of members, and in order to ascertain the probable value of these fibres in the English market, so that planters may be induced to grow and collect them in large quantities for export to Europe. The Rheea plant is already cultivated by the natives of Assam to make fishing-lines and nets. Its shoots can be cut down several times a year, and its fibres they know 6.

But as there is no doubt of the strength and flexibility of their fibres, it is to be hoped that they will, when more generally known, be more extensively employed for ropemaking both in India and England, especially as they can be produced at a price under that of Russian hemp. Neither the royal nor mercantile navy need therefore be restricted to European sources of supply for this essential part of their equipment, but as the Rheca of Assam, like the Chu-Ma of China, produces fibres of different degrees of fineness, according as they are taken from the later or the earlier crops, so may they, though rivalling those of grass cloth in fineness, exceed those of Russian or of Polish hemp in strength.

By limiting the number of purchasers, and thereby diminishing the chances of successful competition, it gives to a few leading journals a species of monopoly, and a power in the direction of public opinion, which is often productive of great injury, while, if the duty were withdrawn, newspapers would become so numerous and cheap, that no individual would confine his reading to one journal, and in accustoming himself to judge betwen conflicting accounts and opposite opinions, he would be less likely than he now is, to be deceived by ex-parte statements and interested falsehoods.

BOSTON.-The lecture season at the Athenæum was commenced about a month since by the Vicar (the Rev. G. B. Blenkin), who lectured on the "Advantages of Literature." On the 25th ultimo, a lecture was delivered by the Rev. A. Lunn (Unitarian). It was entitled, “A Glance at the Freedom of Slavery of Europe." There are at the present time 420 members. The committee have determined on getting up an Exhibition, to be opened after Christmas. Mr. J. W. Bontoft, the Honorary Secretary, will be glad to receive communications on the subject from kindred institutions, and from any one interested in Wed. such matters.

MACCLESFIELD.-The eighteenth Annual Meeting of the Society for Acquiring Useful Knowledge, was celebrated in the Town Hall, on Wednesday se'nnight, the President of the Society, John Brockelhurst, Esq., M.P. in the chair. The President remarked that the success of the Society was proved by the fact that upwards of 5,000 young men had passed through it, some deriving great and lasting advantages from it, some lesser, but all of them some benefit. The trade of the country was now in difficulties-in a panic and dilemma-and he THURS. could assign no stronger reason for Macclesfield feeling so little of it, but that the public were better instructed than elsewhere how to manage their own business, and, as the saying was, "to keep the wolf from the door." And he SAT. was sure that in this respect they were deeply indebted to this institution. He could scarcely hear of a manufacturing house in the town where there was not one or more of the young men educated in the institution assisting in the business. They exhibited a greater degree of intelligence than others; and we all know that upon that intelligence, next to Providence, prosperity mainly depends. The report of the Committee, which was read by Mr. Curwen, the honorary secretary, stated that, since the last general meeting, an additional subscription eading-room had been erected, and that the accommodation for reading now provided for the members was not surpassed by any institution of a similar kind in the kingdom. The reading-rooms were now supplied with ten daily and thirteen weekly newspapers, in addition to five weekly and thirty-two monthly periodicals. An addition of four hundred volumes has been made to the library; and a donation of 201. had been received from Mr. T. Brocklehurst, in aid of the library fund. The classes were in a very prosperous and improving condition, both as respects the numbers in attendance and the progress of the pupils. The annual receipts of the society during the year had been 5667. 13s. 6d. ; the expenditure had been 5627. 12s. 7d leaving a balance with the treasurer of 41. Os. 11d. The Rev. C. A. J. Smyth moved, and Mr. E. C. Egerton, M.P., seconded, the adoption of the report, which was carried unanimously. The president then proceeded to read the reports of the teachers, and the adjudication of the prizes, after which their presentation to the successful members took place.

THE ATLANTIC AND PACIFIC JUNCTION COMPANY.-The
governments of this country, of France, and of the United
States have at length resolved to afford the necessary assistance,
in the shape of an armed force and a staff of engineers, for
completing and authenticating before the world the survey of a
route for the proposed inter-oceanic cut navigable for vessels of
any
size across the Isthmus of Darien. It will be recollected
that this undertaking, of which Dr. Cullen must be regarded as
the originator, was coldly received by the public in consequence
of the large sum (£15,000,000 sterling) demanded for its com-
pletion, and the imperfect character of the report made upon it
by Mr. Lionel Gisborne, the chief engineer of the Company.
It was contended that the first efforts of the Company should
be directed to the task of obtaining a more thorough and satis-
factory survey of the route, and of collecting data upon which
the public might be able to form a definite opinion as to the
practicability of the enterprise. The want of means and other
difficulties would probably have delayed for some time the ac-

for the success of an undertaking so long the dream of great

minds, and so important to the commerce and civilisation of the world, the three leading maritime powers have come forward and offered their assistance. The Government of the United States, having the largest interest in the matter,led the way,but England and France have not been slow to follow the example. On the 17th of this month the West India mail steamer, which starts from Southampton, will carry out to Panama the Government officers and the officials of the Company who are to constitute the British portion of the surveying expedition. Mr Lionel Gisborne and Mr. Ford are, of course, to go out on the part of the Company, and will now be enabled to complete their surveys of the route without encountering the dangers to which they were formerly exposed. Dr. Cullen also accompanies the expedition, and will be its pioneer. At Jamaica the explorers will be joined by a staff of engineers from the United States, under the command of Lieutenant Strange, and they will then proceedwhith two British men-of-war, the French flag-ship from Martinique, and the American Syana, to Caledonie Bay, where their operations will commence. A third vessel from our fleet in the Pacific will, at the same time, be sent round to the Gulf of St. Miguel, and co-operate from that side, so that all difficulties prescribed by the wooded character of the proposed route. and by hostile Indian tribes, will be effectually overcome. A more important expedition for the commerce and civilisation of the whole world has seldom been undertaken, and, looking at the magnitude of the results depending upon it, while all must wish it good speed, the only wonder is that it should have been so long deferred.
