A large mastiff dog picked up a favorite lap dog in the upper part of
the city last week, and ran off with it. He was pursued by a mob, and
after a severe chase, the terrified pet was recovered and brought back
rejoicing.

THE HARBOR OF HAVANA

[Illustration: Havana Harbor]

Our engraving represents a view of the harbor of Havana, which is one
of the most commodious in the world, communicating with the sea by a
channel little more than half a mile in length, and from 300 to 350
yards wide; its depth varying from eight to ten fathoms. The harbor
itself is an oblong basin, surrounded by heights which usually shelter
it from the wind.

Havana is a place of considerable strength, and, besides the walls and
ditches which surround it, the city is defended by six strongholds,
called the Moro, the Cobanas, No. 4, the Atares, the Principie and the
Putna. The first and last serve to protect the entrance of the harbor,
the second is a sort of citadel and the others are so placed as to
cover the approaches by land. The line of fortification, embraces a
sort of irregular polygon of an eliptical form, the greatest diameter
of which is 2,100 yards, and the smallest 1,200 yards in extent. The
entrance between the Moro and Putna, castles is about 1,500 yards
long, and in its narrowest part 350 yards wide. In the arsenal of the
Havana, there have been built 49 ships of the line, 22 frigates, 7
packet ships, 9 brigs of war, and 15 schooners of war.

The town is built on the western side of the basin, near the channel,
on a kind of promon
