International Conference Held at Washington Part 20

There being no objection, the report was adopted.

The PRESIDENT. In the regular order of business to-day, the first subject before the Conference is the resolution offered on Sat.u.r.day by the Delegate of the United States, Mr. RUTHERFURD, with the amendment offered by the Delegate of Sweden, Count LEWENHAUPT.

The resolution is as follows:

"_Resolved_, That this universal day is to be a mean solar day, is to begin for all the world at the moment of mean midnight of the initial meridian coinciding with the beginning of the civil day and date of that meridian, and is to be counted from zero up to twenty-four hours."

The amendment offered is as follows:

"The Conference recommends as initial point for the universal hour and the cosmic day the mean mid-day of Greenwich, coinciding with the moment of midnight or the beginning of the civil day at the meridian 12 hours or 180 from Greenwich.

"The universal hours are to be counted from 0 up to 24 hours."

Mr. VALERA, the Delegate of Spain, said that he thought that the amendment of the Delegate of Sweden should be first discussed.

Mr. JANSSEN, the Delegate of France. At the last session I informed the Congress that I had received a telegram from Sir William Thomson upon the question of the meridian. Since then, that ill.u.s.trious foreign member of the Inst.i.tute of France has written me a very kind letter upon the subject, in which he expresses his complete appreciation of the disinterested att.i.tude taken by France in this Congress. I thank Sir William Thomson for his sentiments towards France, and I am persuaded that, with such excellent feelings, we should arrive at an understanding, upon scientific bases, in which the moral and material interests of all would be equitably adjusted, as we have always understood them.

But the question is not open now, and this Congress would, doubtless, not be disposed to reopen it. Sir William Thomson will understand, therefore, that in the present condition of affairs we have only to maintain the att.i.tude which we have taken and the votes which we have given.

The PRESIDENT. The Chair will simply say to the Conference that he very informally alluded to the letter that he had received from Sir William Thomson, and the Chair would also say in answer to the Spanish Minister that the rule in this Conference, a simple one, is to discuss the last amendment offered and dispose of it, instead, as suggested by the Delegate of Spain, of taking up the one most important in its character. It would be somewhat difficult for the Chair to decide on all occasions which amendment is the most important. I think, therefore, as Chairman, that I will pursue the rule in force in this country, and, unless the Conference order otherwise, shall present the amendment which is the last offered.

Mr. RUIZ DEL ARBOL, Delegate of Spain. Mr. Chairman, the Spanish Minister has not referred to the most important amendment, but to the most radical. For instance, here there are several propositions to select a meridian; one of them must be considered, and it seems to me that my amendment, which is the most radical, is the one to be first presented to the Conference.

The PRESIDENT. Unless the Conference shall direct otherwise, the Chair must pursue the principle on which it has acted hitherto, taking the amendments in the order in which they are offered, and presenting them inversely for the action of the Conference. The proposition before the Conference, therefore, is the amendment offered by the Delegate of Spain, Mr. ARBOL, which is as follows:

"Having accepted the meridian of Greenwich to account the longitudes, as a general need for practical purposes, but thinking that the introduction of any new system of time-reckoning is far more scientific and important, and liable to great difficulties and confusion in the future, we propose the following resolution:

"_Resolved_, The Congress, taking in consideration that there is already a meridian tacitly accepted by almost all the civilized nations as the origin of dates, the anti-meridian of Rome, abstains from designating any other meridian to reckon the universal time."

Mr. RUIZ DEL ARBOL, Delegate of Spain. It is proposed to introduce an absolute universal or cosmopolitan system of time-reckoning, which, it is hoped, will, at a more or less distant day, be generally adopted, not only for scientific purposes, but for all the ordinary purposes of life for which it can possibly be used; and it is further proposed to designate a meridian at which this cosmopolitan time-reckoning is to begin. What I have to state is, that this method of absolute time-reckoning already exists, (although we do not use it,) as does this universal meridian which has been tacitly chosen by almost all civilized nations--that is to say, by all such as have adopted the Julian calendar, with or without the Gregorian correction. Thus it is that anything involving even a slight modification of our present system is nothing more than a chronological reform, which I do not feel certain that it will be well for us to introduce or recommend, and with regard to which I have my doubts whether it will be received with unanimous or hearty approval.

In fact, gentlemen, all nations that have adopted the Julian and Gregorian systems of time-reckoning have necessarily accepted their consequences, and these consequences are, as Rome told us in the time of Caesar and in that of Gregory XIII, that we must reckon our days according to certain fixed dates; some part of the world had to reckon their dates before all the rest, and as Rome consented that countries situated to the east of it should reckon their date before it and countries situated to the west after it, it is evident that both reckonings had to meet at some point on some meridian, which was and could be no other than the anti-meridian of Rome. Nature itself seems to have lent its sanction to this, since the anti-meridian of Rome crosses no continent, and, probably, no land whatever.

Let us suppose, for the sake of ill.u.s.tration, that it were agreed to abandon the Gregorian system of reckoning at a given moment, and to adopt another; that it were agreed to abandon it at all points on the globe when the hour should be twelve o'clock at noon at Greenwich, on the first day of January, 1885; and let us suppose that for historical or scientific purposes we were interested in knowing exactly how long the Gregorian system had been in use. Is it possible to ascertain this? It is; and very easily. Using that system of universal time-reckoning which it is proposed to establish, but logically referring it to the origin of that cosmopolitan reckoning which really exists, that is to say, to the anti-meridian of Rome, we shall find that 1885 years have been reckoned according to the Gregorian system, plus the difference of longitude between the anti-meridians of Greenwich and Rome. Nothing is more certain than this, and there is no other way of solving the problem. As I have already shown, when the Gregorian correction was made, the day which, according to the old mode of reckoning, would have been the 5th of October, was called the 15th of October, 1582; the countries situated to the east of Rome had, however, previously begun to reckon according to the new system (previously in absolute time I mean,) and the countries situated to the west adopted it successively afterwards. Now, then, as that portion of the globe which lies to the east of any given point or meridian is nothing more or less than one hemisphere, and as that which lies to the west is another hemisphere, it is evident that, at the anti-meridian of Rome, the two meridians, which constantly differ by one day in their dates, are confounded, and that the anti-meridian of Rome, being the first one in the world that adopted the Julian and the Gregorian systems of reckoning, is the prime meridian of the world, the meridian by which we now reckon, and ought to reckon universal time, until the establishment of a different system. If we had, at the present time, to settle any question depending on dates, in the region where there is some confusion in regard to them, we should have to do so on this principle. If we desired to compel the entire world to keep a regular and logical account of dates, we should have to do so by compelling all the nations to the west of the anti-meridian of Rome to go on reckoning their dates uninterruptedly after they have begun to be reckoned at the said anti-meridian, and by forbidding all the nations to the east of it to reckon any date until it has been reckoned at the anti-meridian of Rome. For this reason I say that the express designation, for the reckoning of universal time, of the meridian of Greenwich or of any other than the anti-meridian of Rome, involves a chronological reform, inasmuch as it will involve the abandonment of the system to which we now adhere, and which we now use by common consent.

This reform will cause a change of nearly 13 hours--that is to say, 12 hours plus the difference of longitude between Rome and Greenwich, if the meridian of Greenwich is designated as the new initial point of the universal date. I do not believe, however, that you will adopt this choice irrevocably, since its curious and strange consequences may be shown by one example, which I will adduce: This table is of about sufficient extent to allow the difference between the geographical longitude of its two ends to be observed and appreciated.

Let us suppose that these sessions were held at Greenwich, and that the table were placed east and west, so that the meridian intersected it lengthwise; let us further suppose that we had agreed to reckon the new universal time by this meridian--that is to say, by that of Greenwich--and that, in signing the protocol, we wished to set an example to the world by using the universal date, the present civil date and the future civil date, which, by the daily use of the universal date, the nations will or may finally accept, to the exclusion of all others, for the ordinary purposes of life. Well, now, gentlemen, we should bring our own choice into discredit. We could not sign, according to these three dates. As regards the last, we should find that half the table and half the Congress were under one date, and the other half under another; even our chairman, if seated in the middle, would find that he had been presiding over our sessions with his right side in one day and his left in the next.

I may be told that this would happen, whatever might be the meridian chosen, but we could afford to allow it to happen at sea, or in some isolated and uninhabited region where congresses never sit, and where no ray of civilization ever penetrates.

But to return to the reform, what are you going to do? I will say that if, instead of the meridian of Greenwich, you designate the anti-meridian for the reckoning of universal time and for the initial point of cosmopolitan dates for the present, but for the future as the initial point also of local dates, the reform will amount to about an hour only, but it will still be a reform. In a word, the anti-meridian of Rome is the one which now furnishes dates to the entire world, and you propose to make the meridian of Greenwich or the anti-meridian do so in future.

I therefore tell you, if you desire a common hour for postal and commercial purposes, designate no meridian at all; let the railway and telegraph companies, the postal authorities and the governments make an arrangement and select an artificial hour, so to speak, whatever it be the hour of Rome, London, Paris, or even that of Greenwich, but do not make a premature declaration which will be an authoritative one as emanating from this Congress, an apparently insignificant reform, but in reality one of very great importance, since, giving the preference to determinate localities in the face of what is scientific, historical, and logical, you render difficult, in the future, the adoption of that very reform, which will, perhaps, then be more necessary, and which can perhaps then be introduced more intelligently.

You see that I am not speaking in behalf of any special meridian, not even that of Rome, since I admit that the reform may be necessary. You see, and I a.s.sure you, that I have not the slightest wish that the meridian which is to be the initial point of universal time should bear the name of any observatory or place in Spain, although that nation discovered the New World in which this Congress is holding its sessions, and although it may be said of that nation that it discovered those very meridians concerning which we are now speaking, inasmuch as terrestial meridians were indefinite and unknown lines, and were even without form until one was given them by Sebastian Elcano. I therefore hope that if you do not honor my proposition by accepting it, you will at least do justice to my intentions.

Prof. ADAMS, Delegate of Great Britain. Mr. President, I shall be very short in any remarks which I may make upon the proposition before us.

As far as I understand it, it is that, although we have adopted the meridian of Greenwich as a prime meridian from which to count longitudes, we should begin to count our time according to the meridian at Rome. I cannot consent to that proposition. It appears to me to be wanting in every element of simplicity, which should be our chief aim in this Conference. To count longitude from one meridian and time from another, is something that will never be adopted. I do not understand that that was at all the proposition recommended by the Roman Conference. On the contrary, I think that it was quite a different one.

Mr. RUIZ DEL ARBOL, Delegate of Spain. Mr. President, I do not in reality propose to adopt the meridian or anti-meridian of Rome. What I have been contending for is that we should abstain at present from adopting any meridian as a point of departure for the calculation of time; otherwise, we introduce a new element of confusion for the future. We should change the chronological reckoning which is now in vogue, and I contend that we have no right, scientific or historical, to make that change now. According to my views, the meridian of longitude is relatively an unimportant affair. It is a practical one; it cannot be changed in twenty years, probably, and it will take that time to correct all existing charts. But if you adopt a meridian for time, it will be very difficult to alter it in the future. I cannot now clearly see what the difficulties will be, but I apprehend that the application of this new principle to the various details of scientific and civil matters will necessarily be attended with great inconvenience, and may result in proving to be quite impracticable. I understand it very well that it is proposed to confine this principle to certain subjects, and that it is adopted for the purpose of avoiding dangers in communications, in navigation, in railways, and in transmitting telegrams, &c.; but this is purely an administrative matter, and can be left for settlement to other bodies.

The PRESIDENT. The Chair would remind the Delegate of Spain, Mr. RUIZ DEL ARBOL, that at its last session the Conference resolved, with singular unanimity, that it was expedient to adopt "a universal day for all purposes for which it may be found convenient, and which shall not interfere with the local or other standard time where desirable."

The Chair would politely suggest that the subject now under consideration is the adoption of the proposition recommended by the Conference at Rome, and which has been presented here by the Delegate of Sweden, Count LEWENHAUPT.

Mr. RUIZ DEL ARBOL, Delegate of Spain. My proposition is to abstain from the adoption of any one meridian, and that we leave the matter to some other Congress, organized with the special object of regulating this question.

Commander SAMPSON, Delegate of the United States. Mr. President, as near as I can follow the Delegate of Spain, he seems to be under the apprehension that by the adoption of the universal day, which has been proposed here, we should either gain or lose time in our chronology; that we should skip 12 hours, more or less. But, of course, that is not the case. Any event which has occurred, or which will occur, at the time of the adoption of the universal day will be expressed just as exactly with reference to time as if the time had been calculated from the beginning of the Christian era. There will not only be no confusion, but it seems to me the adoption of the universal day will tend to avoid confusion hereafter, because confusion must exist where we have so many standards of time. Now, if any event which is taking place, or has taken place at any past time in the history of the world, is referred to the prime meridian, or is expressed in the time of any locality or of several localities, these times will all be different. The adoption of the universal day is to avoid any difficulty of that sort, and any event which has transpired will, when expressed in the time of the universal day--that is, according to the universal method--represent exactly the interval of time which has elapsed since the beginning of the Christian era. Nothing is gained or lost.

General STRACHEY, Delegate of Great Britain. It seems to me that the Congress having accepted the resolution to which reference was made a little while ago, adopting the universal day, it is inc.u.mbent upon us, in the nature of things, to determine when that universal day shall begin. The resolution presented by the Delegate of the United States proposes to define how that universal day shall be reckoned; that is, when it shall begin and how its hours shall be counted.

It was explained by him that the difference between his proposition and the proposition made at Rome consisted in altering the time of the commencement of the so-called universal day from noon at Greenwich to the commencement of the civil day. Certainly what Commander SAMPSON just said is perfectly true. The adoption of this so-called universal day will not interfere in the smallest degree with any purpose for which time is employed in civil life. The two objects are entirely distinct. It is obvious that the conception of the necessity of having a universal day has arisen from the more clear conception of the fact that time on the globe is essentially local; that the time upon any given line (supposing it to be a meridian) is not the time at the same moment on either side of that line, however small the departure from it may be; and for scientific accuracy it has, therefore, been thought desirable to have some absolute standard to which days and hours can be referred. Up to the present time it has been the practice to say, in an indefinite way, that an event happened, say, on the 1st of January at 6 o'clock in the morning, and such a statement of the time has been considered sufficient; but, in truth, this does not completely describe a definite epoch of time, for if the event occurred at Madrid and was so reported, that report would not designate the same moment as a report of an event which was described to have occurred at precisely the same date and hour at Greenwich, or Rome, or Washington. What is required and desired is that we should have an absolute and definite standard for reckoning events of a certain description, for which complete precision is desirable. I consider, therefore, that the Delegate of Spain leads us astray in the proposition which he has offered, by which he virtually proposes to nullify the resolution already adopted. We have already decided that a universal day was expedient, and it is for the Conference to settle now when that universal day shall begin.

Mr. RUIZ DEL ARBOL, Delegate of Spain. I understand that the consequences, perhaps, would not be troublesome at first; but who can look into the future and say, if we take the meridian of Greenwich as the standard of time, what difficulties we may be driven into? Every country will be obliged to count both ways. They will have to use civil time and universal time. Perhaps all countries may get accustomed to this radical change sooner or later, but we cannot foresee the difficulty now. I have here a treatise (a book) on "a.n.a.lytic Chronology," showing the rules by which to bring into accord different dates of different calendars and eras, and I do not know how they would be affected by this universal time; but it is unnecessary for me to speak of that, as I think you are acquainted with the subject.

Mr. JUAN PASTORIN, Delegate of Spain. The Congress has already come to very important decisions on the subject of the reckoning of longitude, and it will also certainly approve to-day those which have just been submitted on the subject of the universal day.

I say certainly, because the result of the former votes being already known, it cannot be doubted on which side the majority will be, and because, from a scientific point of view, having chosen Greenwich as the prime meridian for the calculation of longitude, and having decided to reckon longitude in two directions from zero hours to twenty-four hours, with the sign plus towards the east and minus towards the west, it will be advantageous to make the civil day of Greenwich coincide with the universal day, if we would have an easy formula for pa.s.sing from local to cosmic time.

So many of the resolutions submitted to the Congress by Mr. RUTHERFURD having been approved one after another, the plan that our colleague has carefully studied will be accepted in its entirety; but it will be impossible for the Conference to know in all their details other plans which, perhaps, would not be less worthy of attention.

Is the resolution adopted by a majority of the Congress the best?

Should we reach the end of the reform in complete harmony with the hopes of all the governments represented here? On the contrary hypothesis, it seems to me, that the sessions of this Congress will only be another step towards that reform, but not the reform itself.

If the majority of the Congress, in accordance with the logical consequence of its work, adopts as the cosmic time the civil time of Greenwich, that decision will be contrary to the most ancient ideas of the human race. For many centuries the day has been reckoned as starting from the east, and the world will not easily abandon the traditions of its predecessors.

The civil day of the world commences near the anti-meridian of Rome, Greenwich, or Paris. Therefore it is not natural that one of these meridians should be chosen as the point of departure of dates.

Really, one phenomenon cannot be the commencement of a series of phenomena if there is another which precedes it periodically.

If the majority, as is logical, adopts the formula, "cosmic time=local time-longitude," and applies in the calculation longitude with the signs plus and minus, according as the longitude is east and west, the system will be source of frequent mistakes, and those, in their turn, will be the cause of disastrous accidents, especially on railroads.

Let us take the 31st of December, for instance. It is three o'clock at a point nine hours east of Greenwich; at the same moment they will count at Greenwich eighteen civil hours of the 30th of the same month, after the actual manner of reckoning the civil day, and that civil time of Greenwich will be the cosmic time.

Apply to the proposed example the formula which I suppose the majority of the Congress will adopt, and the result will be a negative quant.i.ty, minus six hours--a result not sufficiently comprehensible in itself, and one that could not be easily applied by the general public.

Can a majority prevail in questions, such as those we are speaking of, simply by the force of numbers? The whole world for several centuries thought that the earth was the centre of our planetary system; in fact, until an insignificant minority rose against this theory, for a long time considered by their ancestors indisputable.

I will conclude by expressing my opinion upon the subject with which the Congress is occupied. My opinion is not new, in spite of its having been modified in the course of our sitting. The works of our eminent colleague and indefatigable propagandist, Mr. SANDFORD FLEMING, the resolution of the Conference at Rome, the valuable opinions of Messrs. Faye, Otto Struve, Beaumont de Boutiller, Hugo Gylden, the scientific work of Monsieur Chancourtois, and the report which M. Gaspari has just presented to the Academy of Sciences of Paris are the text upon which I base the simplest and most practical method of solving the problem, namely, to adopt as the prime meridian for cosmic time and longitude a meridian near the point at which our dates change, and to reckon longitude from zero hours to twenty-four hours towards the west, contrary to the movement of the earth. The formula would be then: Cosmic time = local time + longitude.

I think that the best way of finding cosmic time in relation to local time and longitude is to add a quant.i.ty to the civil hour of each point of the globe.

But as the majority of this Congress, so worthy of respect, admits no modifications of the system which we may call Greenwich, let us lay aside the question of longitude and consider cosmic time separately.

I have the honor, therefore, to present the following resolutions, and I ask the Congress to consider them, and to accept them as a means of compromise:

I. We agree to choose as the prime meridian for cosmic time that meridian near which the civil day of the world commences, namely, the anti-meridian of Rome, Greenwich, or Havre.
