11,500,000 square miles, should carry 786,000, 000, whilst there are actually about 1 260,000,000. America, North and i South, has 15,000,000 square miles, nnd an actual population of bnrely 101,000,000, against a possible 950, 000,000, a"d finally, Oceania, with 8,500,000,000 square miles, has room for 280,000,000, the aetoti population being probably not much over 4,000, 000. Thus we find that, whilst Europe has an overplus of sixty millions. Asia has yet room for 250 millions, Africa for say MO million?, America for say 860 millions, and Oceania for 900 millions; so that, deducting Europe's small overplus, there is yet space for over 1,700,000, 000 of human beings. A further ana'ysis shows that, whilst Belgium has not more than ao acre and a quarter per head and EnfUmf only an acre at d a half per head, and are therefore carry iug from seveu to eight times their pro per quota, Oceania has about 700 acres, to each individual; South America 160 acres, and North America 80 acres. In regard to the latter, how ever, whilst the United States are already so far settled up, that, includ ing the Arctic Alaska, that have only 45 acres per head, British America has actually over 500 acres per head. We have now to consider the in fluences which am at work filling up this immentt* vacunin : and which am sufficiently powerful to make, em long, this qnestion of population a pressing one. If the rate of increase which lias prevailed dm ing the. last century i in this conntry, in the United States, j and in Germany weie to become general and continuous, another cen^ tiny wonld suffice to till the world to overflowing. Taking the average of increase, in this country and the United States, it wonld mean a doubling i of the population 1 at least every half ' century ; aud the world ata ( can only I stand a little more than one doable. ! Iv 17S0 the British Isles had a population of only twelve and a half millions ; it it now three times j that figure; whilst in the States tun j population has increased within the century at least tenfold.
