NISSEN STAMPS
FOR BOSTON CON.
Over Three Hundred of Them
Will Be Placed in Com
pany'S New Mill.
TESTS PROVE SUPERIORITY
CONSTRUCTION OF PLANT WILL
NOW BE PUSHED.

Late yesterday afternoon Lafayette
Hanchett, in behalf of the Boston Con-
solidated company, closed a contract
with Neil NJ Macdonald, head of the
mining department of Fairbanks, Morse
& Co, for 312 Nissen circular indie
pendent stamps and mortars, which
will become a part Of the great 5000
ton concentrating mill that the Boston
company is erecting at Garfield. The
order was placed after negotiations
that consumed the greater portion of
the day and under terms that were fin
ally made agreeable to both sides.
The stamp in question is an entirely
new departure in its particular field of
usefulness in the dressing of ore, and
it's inventor, Peter Norman Nissen, has
been personally watching the tests that
have been carried on at the Boston Con-
solidated company's test mill since En-
gineeF A. J. BEETLES decided to give the
new invention a trial. The tests to
which it has been subjected have been
Of the severest kind and II is a COM
plinent to the inventor that he won
out I'm the struggle against the tried
stamps and other devices which have
held the field for many years.
The fact that the Boston Consolidat-
Ell company's metallurgical engineer
has finally pronounced in favor of the
new device admits Of no other con-
structiOn than that the company eX-
poets better results from il than from
any of the number that have been tried
out at the company's test mill at Bing-
ham. For two or three weeks past the
stamp has been in operation and its
capacity for handling a large tonnage
has been satisfa Ctorily demOnstra ted.
As a matter Of fact it is certain that
each stamp can be depended upon to
crush better than ten tons of ore per
day to the f1neness required by the
character of the ore as determined by
Engineer A. J. BEETLES in the eXhaus>

The selection Of the crushing ma

thing which has been taking up the
time Of Mr. BEETLES lately. the char

having previously been pretty well set
