To make you see this, I must once again resort to some statistics.
England's area--herself and adjacent islands--is 120,832 square miles.
Her population in 1811 was eighteen and one half millions.

At that same time our area was 408,895 square miles, not counting the recent Louisiana Purchase.

And our population was 7,239,881.

With an area less than one third of ours (excluding the huge Louisiana) England had a population more than twice as great.

Therefore she was more crowded than we were--how much more I leave you to figure out for yourself.
