   THE DREADNOUGHT BOYS ON BATTLE PRACTICE.
     Especially interesting and timely is this book which introduces the  reader with its heroes, Ned and Herc, to the great ships of modern  warfare and to the intimate life and surprising adventures of Uncle  Sam's sailors.
   THE DREADNOUGHT BOYS ABOARD A DESTROYER.
     In this story real dangers threaten and the boys' patriotism is  tested in a peculiar international tangle. The scene is laid on the  South American coast.
   THE DREADNOUGHT BOYS ON A SUBMARINE.
     To the inventive genius--trade-school boy or mechanic--this story has  special charm, perhaps, but to every reader its mystery and clever  action are fascinating.
   THE DREADNOUGHT BOYS ON AERO SERVICE.
     Among the volunteers accepted for Aero Service are Ned and Herc.  Their perilous adventures are not confined to the air, however,  although they make daring and notable flights in the name of the  Government; nor are they always able to fly beyond the reach of  their old "enemies," who are also airmen.
   Any volume sent postpaid upon receipt of price.
