The " Field" Boiler.

Mr. Edward Field, the civil engineer, has lately perfected,
we understand, a simple boiler, which, having been in ex-
tensive use in factories and fire engines, is now being intro-
duced into steam ships. The water is made to pass, simply
by its own circulation, in regular and steady currents along
tubes contained in the hottest part of the fire, absorbing
and carrying off its heat in the form of steam with amazing
rapidity. As evidence of its safety, it is only necessary to
state that in case of shortness of water there is no fear of
explosion, and no part of the boiler can be injured except
the tubes, which would give way and simply extinguish
the fire, and these tubes can readily be renewed at small
cost.

By the rapidity of the circulation the boiler possesses
self-cleansing properties, while the simplicity of its con-
struction renders any examination and repair easy of ac-
complishment. Entire freedom from leakage and unequal
expansion is also worthy of notice. The saving in fuel has
been calculated at 20 per cent., while the small space oc-
cupied, owing to the efficiency of the heating surface, is a
matter of great consideration.

By calculation in 25 years the population of the
United States will be GO millions—the most formidable
nation in the world.—Delencla est Carthago.

ANTHROPOLOGICAL SOCIETY OF LONDON.--The
society will meet on Tuesday, December 5, at eight o'clock

THE LORD MAYOR'S LUNCH.--We wait a little
time, when suddenly there enters the well-known
gentleman in the fur cap, who carries the sword ; also, the
other equally well known gentleman, who carries the mace.
Behind them follows agentleman usher with a white wand,
who announces the Right Honourable the Lord Mayor,
who appears for the first time in the state robes of his office.
If you ask me how he looked, I answer that he looked jolly.
There was a hearty shaking of hands all round, many bluff
congratulations were interchanged,some jokes were passed,
and then without ceremony ororder of our going, we trooped
out into another apartment to lunch. It was a plain
substantial feast of roast beef and boiled potatoes. I did not
think I wanted any lunch, but I was told by an experienced
person that the procession was a trying ordeal, and that I
had bettor "lay in a good solid foundation." So I accepted
the seat that was kindly offered to mo by the Lord Mayor,
.and fell to. I should have thought that his lordship would
have been too Tench occupied thinking about all ho had to
go through, not to mention the speeches he had to make,
to take any notice of me, or anybody else. But no, his
dignity and his duties sat lightly upon him ; and I say
again, he was jolly. He asked me to take wine, he asked
me to join him in a loving and warming cup of hot older
wine, to keep out the cold—for "I should find it very 'chilly
in the carriage." He was collected enough and thoughtful
enough to remember that the cavalry officers had ridden
all the way from Hounslow that morning, to command
his body-guard, and sent out for them to share in the feast
The young swell in the red coat, who sat next to me,
said he never was so thankful for a slice of beef in his life.
"And was'nt the Lord Mayor a brick for thinking of
them ?" If we could only have stopped round this lunch-
table, I am sure we should have spent a very pleasant
afternoon. A little longer, and we should have got pok-
ing each other in the ribs, telling each other our family
affairs, and inviting each other to dinner at our respective
family mansions. But the sword of the Damocles in the
fur cap was imminent over us, and when the sword
pointed the way we had to follow.—Dickens's " All the
Year Round."
