A Speculation in Rifles
Clarence H. New
Published in The Blue Book Magazine, Apr 1909.
After Alicia Noyes informs Grisscome of learning about a shipment of 200k cheap rifles from Germany to some unknown location, Grisscome deduces it will be to the East Indies (likely the Malay Peninsula) where 'Mohammedans' want to take over. He gets the President's permission to sail the Mirage to destroy the arsenal once it arrives. Use of an early form of submarine will be involved.
