we close this list with a Chinese
proverb which should be inscribed on the lintel of every door
in Christendom: "The happy-hearted man carries joy for all the
household."

MASON AND DIXON'S LINE.--Mason and Dixon's line is the concurrent
State line of Maryland and Pennsylvania. It is named after two eminent
astronomers and [Transcriber's Note: The original text reads
'mathemeticians'] mathematicians, Charles Mason and Jeremiah Dixon,
who were sent out from England to run it. They completed the survey
between 1703 and 1707, excepting thirty-six miles surveyed in 1782 by
Colonel Alex. McLean and Joseph Neville. It is in the latitude of 39
deg. 43 min. 26.3 sec.

GREAT FIRES OF HISTORY.--The loss of life and property in the willful
destruction by fire and sword of the principal cities of ancient
history--Nineveh, Babylon, Persepolis, Carthage, Palmyra, and
many others--is largely a matter of conjecture. The following is a
memorandum of the chief conflagrations of the current era:

In 64, A. D., during the reign of Nero, a terrible fire raged in Rome
for eight days, destroying ten of the fourteen wards. The loss of life
and destruction of property is not known.

In 70 A. D., Jerusalem was taken by the Romans and a large part of it
given to the torch, entailing an enormous destruction of life and
property.

In 1106 Venice, then a city of immense opulence, was almost, wholly
consumed by a fire, originating in accident or incendiarism.

In 1212 the greater part of London was burned.

In 1606 what is known as the Great Fire of London raged in the city
from September 2 to 6, consuming 13,200 houses, with St. Paul's
Church, 86 parish churches, 6 chapels, the Guild Hall, the Royal
Exchange, the Custom House, 52 companies halls, many hospitals,
libraries and other public edifices. The total destruction of property
was estimated at $53,652,500. Six lives were lost, and 436 acres burnt
over.

In 1679 a fire in Boston burned all the warehouses, eighty dwellings,
and vessels in the dock-yards; loss estimated at $1,000,000.

In 1700 a large part of Edinburgh was burned; loss unknown. In 1728
Copenhagen was nearly destroyed; 1,650 houses burned.

In 1736 a fire in St. Petersburg burned 2,000 houses.

In 1729 a fire in Constantinople destroyed 12,000 houses, and 7,000
people perished. The same city suffered a conflagration in 1745,
lasting five days; and in 1750 a series of three appalling fires:
one in January, consum
