along lines which were not expected
In the discussion which followed,
the matter Of The influence Of Annap-
lois upon the plan of the City Of
washington was brought NJ, but no
definite proof Of the fact was forth
looming 1t was pointed out. how-
ever, that the similarity could hard

iIngton had an intimate acquaintance
with this city prior to the founding
/ of the city which bears his name.
Al very informing talk on early
English machinery vas given BY Mr..
Julius Pratt. He said thar while the
deveiopment OF machinery as We know
liz began with the Introduction Of
steam power. there were still many
very intrsting and important types
in use In England at an early date, and
the sixteenth century marked great
development Of several types.
The water mill was mentioned a.
an early type Of machine, and II was
pointed out that its use Was largely
| I'M connection With pumping water
from the coal mines. The speaker
said that one type was the endless
chain with buckets Of wood or leath-.
cir. and later one, the chain moving
through q pipe and bound st inter
walls with clothes Or other material,
thus forming the old rag and-chairi'
pump
The great water-mill under London
bridge was cited as an example of
more ambitious type Of machinery,
and ii was explained in considerable
detail, and its capacity shown It was
waterwheel Of the we'll known un-
dershot type. Machinery was also
used ii connection with ore smelling
lat first relying upon the currents
0f wind for their operation, and later
using bellows worked by waterpower,
Wind power motors we're also used
at later period.
Another use OF machinery, the
speaker said, was III metal stamping
and iii fuiling cloth. These devices
we're based on d hammer ct the end
Of pole on a fulcrum the power be
ling applied at the other end In the
form o9 i water mill. The trade Of
the fuller was that Of cleaning the
cloth after 1t had been woven and
az first It was done BY tramping out II
the vats with the bare feet, and form
ed regular trade.
An interesting side issue, pointed
out By the speaker. was the foretaste
az much subsequent labor trouble. IN
the EFFORTS oil the London fullers to-
prevent clothes being sent out Of the
city to be fulled By machinery. They
secured an order 0f the City Council
or London against II, and, finally, an
act Of Parliament.
The Fourth Dimension
The final address Of the evening
was on the Fourth Dimension and
Was made Ay ME-. Arthur Kiernan, 81
| the Mathematics department Of the
Naval Academy. This very technical
subject was treated III q way TO excite
very lively interest, and q number
participated Iii the discussion. Mr..
Herman made II clear that the fourth
dimension was 8 mathematical as
sumption and that II was not pos
sble FOR US. with our present knowl-
edge, to gain any conception Of II as
an actual fact
He said, however that the assump-
ton had furnished b basis for much.
scientific hypothesis and haa even en-
tered the realm Of psychology and re-
ligion By suggesting q location for
spirits and. to some. an explanation
lof certain Biblical statements.
Mr.. Herman pointed out the popu-
lar error Id regard to mathematical
axioms. He said that these we're
merely hypothesis which furnished d
working basis along pertain lines. and
were not settled truSAs. He said that
they had changed from time 70 time,
and some branches Of mathenat tics
had to be rewritten.
II vas pointed out that there are as
sumptions In other hraches of science.
