America and Britain. By Professor A. C. McLaughlin. (J. M.

Dent. 4s. 6d. net.)—Last spring Professor McLaughlin, of Chicago, visited London and lectured on America's entry into the war, British-American relations, the Monroe Doctrine, and the sources of the American Constitution. These admirable lectures well deserved printing. The author firmly believes in the alliance of the English-speaking peoples. If Great Britain and America, he says, "striving to give expression and greater reality to actual international solidarity, can create the Monroe Doctrine of the world, then all past achievements will seem as tinsel, save as they prepared that consummation." He sketches the evolution of the Monroe Doctrine, which has applied, of late years, mainly to Central America, and he urges that in the event of a complete victory for the Allies, which has now come to pass, the Doctrine "need no longer be defensive and pro- vincial," but may be extended to mean "a principle of decent and humane relationship between nations." In the final lecture the author endeavours to show that the makers of the Constitution adopted the idea of federalism, with a separati n of powers, from the old British Colonial system.
