How the World Has Grown.

Taline the century through. the estl- mate of the worlds population IS SlV, was 6s3 o0O.0 GOO In 1928 this had increaseu to 847. .000 900. a gain of l2 in the loOo' anu the greatest growth of the century !" lS45 the population of the world was l'- OO9 oO0. .Oo0. an average of 10 In the l,VVV TOT that neriod; between 1S45 and 1874 the increase was il in the 1000. but between the year 1874 and 1900 the increase WAS only 6 to the 1,0O0 population
 The world has a population of 1,6oO mil lions in 1900. with a proportionate popula- tion for the world Of only thirty-one to each square mile. When 1t has a popuia- ton of 1O0 to each square mile, 1t VIII be full to It's capacity for sustaining life.
 When will that be, at the average rate of ten increase to the 1000?
 Starting with the 1,600 million people in the world a the beginning of the twen- tieth century. this rate of increase Will give 432S millions in the year 2,00O, with eighty-three people to the square mlie' there will be II, FOG millions in 2l0O with 225 people to the mile; 31,662 millions in 22o0 and 6o9 to the mile; and in the year 2950 there will be 52073 millions of people in the world, and the necessity of giving to them for all purposes only two-tnirds of an acre each. This per capita allow ance of two-thirds of an acre must in- clude the square miles given over to rail- roads, highways cities, factories, ana all the purposes of civilization which render the surface of the earth unproductlVe ot food for man.
 A possible population of 1.OO1 to the square mile necessarily presupposes that in the next $50 years there will be marked improvements in everything tending 10 the economies of civilized life; that new
 lad less unproductlve shall be made to yield sup port for man, and that in every line of transportation and distribution of the necessaries of life. speed and economy shall be attained to the full.
 Belgium Most Densely Populated.
 At the present moment Belgium, with It's 59S people to the square mile of ter ritory, has approached the suggestion of a full world Here ;he problem of trans portation became one of the chief mat ters of solution. In its territory the size of the State of Maryland and with six times the population of that State, Bel gium has 2s67 miles of railroads. 5,743 miles of improved highways, and 1870 miles of navgable inland waters.
 In the United States little Rhode Is- land supports 395 people to the square mile. thus holding the palm over all the other States in the Union, As a sugges- tlon of the further possibilities of popu- lation in the United States it may be re- marked that while the world average Is thirty -one to the square mile, that of the United States is only twenty-one to the same space With the density of the Rhode Island population holding over the entire territory of the Union, the total population would he 1173,15O,0OO for the United States, exclusive of its island pos sessions.
