The elaborate entertainment fea-
lures OF the convention were again in
evidence on Tuesday evening when an
informal smoker and entertainment
was held amid great jollity. Practical
jokes were perpetrated on those pre-
sent and stories were related OF those
members in the Far West and in other
countries until an hour OF the night.
On the third day OF the meeting
"wednesday Lieut. Commander Har-
old Earle Cook. u. S. Navy, addressed
the meeting on Autobiography OF
Steel for United States Naval Ordin-
ance" and explained that microscopy
ic inspection OF the Steel used for war
supplies was today OF almost untold
value and that the Government was
more and more standardizing its
specifications for war equipment.
Great interest was later displayed
when +. A. Fahrenwald, OF Cleveland,
Ohio. introduced the subject OF sub
stitutes for platinum. The positive
conclusions which Mr.. Fahrenwald
drew from his discussion were that
although metals or alloys OF metals
outside of the precious-metal groups,
are unsuitable as substitutes for plat
mum, nevertheless the gold and silver
alloys OF palladium have been found TO
be excellent substitutes for platinum
in its softer forms and while not so
chemically resistant, fill all require
ments where conditions are not too
rigid.
The fact is also developed that ex-
cept in two respects, pure ductile
tungsten, and, TO lesser degree,
molybdenum. meet all OF the specifica-
tions of practical substitute for
platinum and its alloys. These two
defects are its ease OF oxidation, and
the difficulty with which It can be sol
dered; and they have been overcome
by coating with precious metal on
alloy, the resulting material being in
many ways far superior TO platinum
or its alloys.
This material has met with instant
demand, is i'm many cases replacing the
best platinum-iridium alloys, and per-
mits the performance OF work which
has been impossible with the materials
/ hitherto available.
on Wednesday evening the annual
dinner OF the Institute was held in
/ Hotel Astor and this was followed by
dancing. ON Thursday the entire day
