Among the numerous marvellous inventions
which American genius has produced within
the last few years, are the following, compiled
from the Patent Office Report:
The Report explains the principles Of the
celebrated Hobbs lock. Its unpickability de.
pends upon secondary or false set of tum-
blers, which tNrehes the real ones. Moreover
the lock isyp0wder- proof, and may be loaded
through the key hole and fired or until the
burglar is tired Of his fruitles work, or fears
that the explosion may bring, to view his ex-
periments, more witnesses than he desires.
A harpoon is described which makes
whale kin himself. The more he pulls the
deeper goes the harpoon. suigh a'a jigi
An ice-lnaking machine has been patented,
which is worked by steam engine. In an
experimental trial it froze several bottles Of
sherry, and produced blocks Of ice the size Of
a cubic foot, when the thermometer was up
to eighty degrees. It is calculated that for
every ton Of coal put in the furnace, it will
make ton of ice.
From Mr.. Dake's report we gather some
idea of the value Of patents. A man who
had made slight Improvement in straw cut
ters, took model of his machine through the
Western States, and after a tour Of eight
months returned with forty thousand dollars.
Another man had machine to thrash and
clean grain, which in fifteen months he sold
for sixty thousand dollars. These are ortlin-
ary cases, while such inventions as the tele-
graph and India rubber patents are worth
millions each. &nis' 34asH'

inventions. Among these is an electrical
