The Jewish population of Jerusalem Jeru-salem has increased from about 10,-000 10,-000 to not less than 50,000 out of a total of 90,000, including people of other races. Religious organizations beside the Jewish have built fine mansions, but nobody has done much for the improvamont of housing or laying out suburbs, the rosult being rows of wretched slums between the great stone churches and other cost-1 cost-1 buildings. Now, however, a practical prac-tical scheme for extending thj philanthropy phil-anthropy of Sir Moses Montoflore, towards which some $60,000 was collected col-lected in Englnnd ns a memorial, has been established. This has been expended ex-pended in the oroction of suitable buildings for the poor, five suburbnn colonies having been established with from sixty to seventy houses each, the newest costing not; less than $1,000 each. Now n project has been started in England of forming a new garden suburb outside Jerusalem in which the houses can be let to the better class nrtisians who can afford n rent of 40 or $50 a year. The half acre of ground and the house thereon there-on is estimated to cost not over $1,000 in all. The garden can be planted with figs, olives, and garden products, from the sale of which the occupant can make a little income. Scientists- have Indulged in some interesting, speculations ns to the possible pos-sible increase in the length of our day. It Is pointed out that when once the earth "has started in motion about an axis. It must, of course, continue forever euwl at the sumo rate, thus making the day always of the same length, unless something is happening or will happen to interfere with that motion. Now there are several causes In operation that affect the period of the earth's rotation, some of which tend to make the period less and others to make it greater. The Influence In-fluence of each of the causes lc, of course, very small. They are generally gener-ally easy to understand. A very simple experiment Illustrates one of them. A stone is attached to one end of a string, the other end of which is held in the hand. The stone Is then whirled around in a circle. When its speed has become nearly uniform the string Is .allowed to wind up on the finger. It Is noticed that as the string shortens the velocity increases. In the same way, if the matter forming form-ing the earth should in any way be drawn nearer to the axis of rotation, it would turn fr.-ner and the day would be shortened. By continual loss of heat a shrlnk- age of the earth is probably in progress; prog-ress; and although the process Is exceedingly ex-ceedingly slow it certainly tonds to diminish the pelrod of rotation. On the other hand, any addition of matter mat-ter from the outside will tend to increase in-crease that period and make the day longer. There seems to be hd question ques-tion but that slight additions to the mass of the earth are constantly made by the arrets of motooric bodies passing pass-ing through the atmosphere. Their influence Is opposed to and tonds to neutralize that of any earth shrinkage shrink-age that may be taking place. The most important interference with the rotathjn of the earth of which we have knowledge is that of the tidal waves, which are due to the attraction attrac-tion of the sun and moon, but more largely of the latter. It is easy to soe that this Is a resistance against which the oarth turns, and its effect is to increase the longth of the day. Astronomical observations extending extend-ing over a period of two thousand yours have fulled to show any sensible sen-sible changos In the day, but the influence in-fluence of the tides must become ovident after the la,pse of n great many years. One authority has declared de-clared that tl,o day may lengthen until it Is at least fifty-five times as long ns it is at present; and that would alsjj b the period of the revolution rev-olution Qf the moon about the earth. A day Of thirtoon hundred and twenty twen-ty hpurs is not, however, llkoly to come for sone millions of years. Few persons who admire the Iri-dosonce Iri-dosonce of ancient glassware know that the prismatic hues displayed are a result of the decay of the glass. When disintegration sets In, the substance sub-stance of the glass splits into exceedingly ex-ceedingly thin laminae, which, ns the sunlight traverses them, give rise to a splendid play of colors. Like the leaves of a forost, these delicate glasses signalize their approaching dissolution by becoming mope beautiful. |
