"Taking the Nation in the aggregate, and we find its population and ratio of increase, for the several decennial periods, to be as follows:

"This shows an average Decennial Increase of 34.69 per cent. in population through the seventy years from our first to our last census yet taken. It is seen that the ratio of increase, at no one of these seven periods, is either two per cent. below or two per cent. above the average; thus showing how inflexible, and, consequently, how reliable, the law of Increase, in our case, is.

"These figures show that our Country may be as populous as Europe now is at some point between 1920 and 1930—say about 1925—our territory, at seventy-three and a third persons to the square mile, being of capacity to contain 217,186,000.
