1st. An equinoctial year unit for the astronomers, divided somewhat as suggested, but no attempt to make the divisions even approximate to days and hours. This would fix all astronomical events, absolutely. A variation in the length of the year would not disturb this system, since the year _itself_ would be the unit. In translating this astronomical, or year unit time, into clock time, no difficulties would be added, as compared with our present translation of sidereal time into clock time. Deal with the _year unit_ and _day unit_ separately and convert them mutually when necessary. 2nd. A universal mean time day of 24 hours, as now kept at Greenwich, all human business being regulated by this time. Dates and the date line as well as leap years all being retained as at present. 3rd. Weight and spring clocks and watches to be superseded by the cosmic clocks and watches regulated by wireless impulses from central time stations, all impulses giving the same invariable time for all places. 4th. Automatic recording of the earth's rotations to determine this time. To avoid any possibility of misunderstanding, I would advise never counting a unit till it is completed. We do this correctly with our hours, as we understand 24 o'clock to be the same as 0 o'clock. But we do not carry this out logically, for we say 24.30. How can this be so, since there is nothing more than 24 o'clock? It ought to be simply 30 minutes, or 0 hour 30 minutes. How can there be any _hour_ when a new day is only 30 minutes old? This brings up the acrimonious controversy, of some years ago, as to whether there was any "year one." One side insisted that till one year was completed there could only be months and days. The other side argued that the "year one" commenced at 0 and that the month and date showed how much of it had passed. Test yourself,--is this the year 1909, of which only 8 months have passed; or is it 1909 and 8 months more? Regarding the centuries there appears to be no difference of opinion that 1900 is completed, and that we are in the 20th century. But can you tell whether we are 8 years and 8 months into the 20th century or 9 years and 8 months? It ought to be, logically 1909 years _complete_ and 8 months of the next year, which we must not count till it is completed. Take a carpenter's rule, we say 1/4 in.--1/2 in.--3/4 in., but do not count an inch till we complete it. When the ancients are quoted,--"about the middle of the third hour" there is no mistake, because that means 2-1/2 hours since sunrise. If we said the 1909th year that would be definite too, and mean some distance into that year. Popular language states that Greenwich is on the "first meridian"; strictly, it is on the zero meridian, or 0°. These matters are largely academic and I do not look on them as serious subjects of discussion; but they are good thought producers. Bidding you good-bye, for the present, it might
