 the conquest of new worlds slowly and surely, 

 nor ever cedes an inch of the territory gained. But 

 the advance is covered and facilitated by the ceaseless 

 activity of clouds of light troops provided with a 

 weapon — alw^ays efficient, if not always an arm of

 see, or think they see, a chance ; and cheerfully to 

 accept defeat, or it may be annihilation, as the reward 

 of error. Unfortunately the public, which watches 

 the progress of the campaign, too often mistakes a
