The national wealth of the United States is estimated to be well over $400,000,000,000. Our annual export trade is close to $5,000,000,000. It is approximately the same as the export trade of Great Britain, and exceeds the export trade of any other country. Not only does our annual export trade equal or exceed that of any other nation but, in addition to this export trade, the value of our coastwise trade, excluding the traffic on the Great Lakes, is greater than the value of the total foreign trade of any other nation. Otherwise stated, the value of our foreign commerce plus the value of our coastwise traffic is more than twice the value of the foreign commerce of any other country. Our coastwise trade extends from Maine to Alaska, covering a distance only slightly less than that from England to Australia.
