I picked it up randomly In a bookstore and read it. I thought it was very interesting but I can not find a single review/discussion of it online anywhere. It touched on a lot of interesting things but seems to be completely forgotten. Despite being written in 1930 he really had a sense that the British empire was in trouble due to increasing economic domination by America and weakening control of the dominions. He also spends much of the book lamenting British economic doctrine blaming England for failing to properly invest in the colonies leading to America's rapid development over places like Canada. Also a lot of interesting stuff about carries that seem relevant today.
