ossible for the force at his disposal
to accomplish. He always commanded the respect and confidence, as well
as the good will, of his men. A strict disciplinarian, the prompt and
unhesitating obedience to orders he exacted was cheerfully rendered by
his subordinates. His plans were coolly and deliberately formed, and,
having been once determined upon, were carried out with energy and
resolution. In the ordinary intercourse of private life he was so
gentle, generous and genial that his friends and associates felt for
him a regard approaching affection. In youth he was an eminently
handsome man and in maturer years his presence was imposing. Sailors
and Indians are fond of giving personally descriptive names to those
with whom they are thrown in contact; when Tucker was a lieutenant he
was called "Handsome Jack" by the men-before-the-mast, and the
warriors of the savage tribes that wander about the head waters of the
Amazon knew him as the "Apo," the meaning of the word being "High
Chief."

In concluding this sketch of the eventful life of John Randolph
Tucker, it is but doing justice to his memory to say that the
sea-service never produced a more thorough and accomplished sailor,
and that there never was bred to the profession of arms a more
honorable and gallant gentleman.

THE AMAZON.

Springing from Lake Laracocha, in the heart of the Andes, the Amazon
winds its way through the eastern Cordillera of Peru, a rapid and
turbulent stream, until, passing through a narrow gorge in the
mountains at the pongo de Manseriche, it leaps into the lowlands and
flows for two thousand six hundred and sixty miles in a direction
nearly east through the vast plains of Peru and Brazil, fed on its way
by tributaries which are themselves great rivers, and finally pouring
its immense volume of water into the Atlantic ocean. From the Atlantic
up to the Peruvian frontier the river is known as the Lower or
Brazilian Amazon, and sometimes as the Solimoens; above the Brazilian
frontier the river lies wholly in Peruvian territory and takes the
name of the Peruvian Amazon or Maranon, but is commonly spoken of as
the Upper Amazon. It is of the
