Volume 150 — THE CHALLENGE.
Reading edition
"HALT! WHO COMES THERE?" "NEUTRAL." "PROVE IT!"
["What I would say to Neutrals is this: Do they admit our right to apply the principles which were applied by the American Government in the War between North and South—to apply those principles to modern conditions and to do our best to prevent trade with the enemy through neutral countries? If the answer is that we are not entitled to do that, then I must say definitely that it is a departure from neutrality."—Sir Edward Grey.]
