THE SAVINGS OF SCIENCE.

THE SAVlh6S UF SClENCk.
Doubtless many Of our readers have pc
rnsed Dickens excellent novel "0ur Mu-
tual friend, and hence are, in measure,
familiar with the London dust heaps.
Perhaps it will be remembered how the
great writer describes their contents, and,
in his inimitable style, sketches the queer
people who often spend their lives among
them seeking for treasures Those patient
searchers are creations Of the past. Their
toilsome occupation is gone for Science,
with her inventions and processes, has ex-
tended her sway even to the worthless dust
heaps, and from the filthy waste brings
out the shining gold. The ordinary waste
Of a single household may be roughly esti-
mated at barrelful per day, and London,
il is said, contains FIVE hundred thousand
houses. Hence, the reader may form some
idea Of the wonderful ingenuity which
contrives to utilize the enormous aggregate
Of one hundred and eighty million barrels
of refuse in the course Of single year.
The local authorities Of London sell the
privilege Of removing dust and garbage
from each district to contractor, who
carts it away to large yard in tho suburbs.
