concern, is connected with the lnter7
national Pump Company.
Mr.. Vermuefe's Report.
The experts report on the award
ing of he contract, with the excep-
tion of a few tabulated figures, is as
follows:
Board of Water Commissioners,
City of Perth Amboy.
Mr.. Patrick Convery,
President.
Gentlemen
have examined the bids for
pumping engines received by you on
the 30th day of August in response
to advertisement, and beg to report
thereon as follows:
1 will consider first the bids under
Glass A of the specifications, which
were two in number.
The bid of the Camden Iron Works
is deficient because 1t has not been
verified by oath, as required In Sse-
ton 3 of the specifications, and as
provided for in the blank form OF
affidavit following the proposal.
This bid is Furthermore informal
in that the plan shows the Condenser
attached to the suction pipe instead
of to the delivery pipe, as required
in Section SO of the specifications.
For the above reasons this should
be rejected. The bid of Henry X.
Worthington complies in all respects
with the specifications. The price Is
, net materially higher than that in
!, the informal proposal of the Camden
Iron Works. The Worthtngton en-
CINE has a larger low pressure CYL
Under and a larger plunger than that
: offered by the Camden Iron Works,
: audit occupies only 1872 square feet OF
floor space, while the Camden En-
CINE occupies 344 square feet. The
Worthington engine will, consequent
ly, call for a smaller en-
9 CINE house, and this saw
ing in cost will very much more
II than offset the difference in the
price of the engine. 1t is therefore
!, to the interests of the city to reject
n the informal bid of the Camden Iron
n Works, and If a contract Is awarded
for an engine in Glass A, 1t should
,s be awarded to Henry r. Worthing-
l. ton.
:. Considering next the bids under
II Glass B.
,s The lowest bid is that of the Ais
Chalmers Company, but on an ex
animation Of the plans and bid
w find that this company has bid upor
g q type of engine much inferior u
that offered by the next bidder, tn
Snow Steam Pump Works. The tw'
engines are of a radically differen
n tyne. The Allis-Chalmers Compan,
81 offers a combination of a cross com
= pound steam engine of the Reynolds
"a Corliss type, with a pump or waite
end connected to the engine by ex
70 tending the piston rods backward
h through the cylinder heads. Such
design must be considered a make
is shift for & NRnmping engine. 1t J
not sometimes used because it allows tn
NV builder to- make use Of patterns ina
ee he may have had at hand for a mi
: engine BY attaching TO 'fNpump. !
mi is not a homogeneous, compact an
al we'll designed pumping engine. 70
nle convenience | will compare some Q
it's features with the engine offere
MIS- by the Snow Steam Pump Work'
m The Snow engine is an engine design
ed for pumping solely in accordanc
with good engineering practice. Tn
nlv Allis-Chalmers engine has the 10
,sa lcwing important defects: 1t occl
,rs' pies unnecessary floor space, manner
IN 761 square feet against 525 squal
IN feet for the Snow engine. 1t is ne
,an proportional TO obtain the best me
as hanical effects, or maxium strength
la stability and stiffness. The differen'
in this respect appears from the Ia
no that while the Snow engine occupl'
ire only five hundred and twenty h'
on sqhlare feet of space, 1t weights o2u
Ok0 pounds, or 600 pounds p'
%suare foot, whereas, the Allis-Cha
in &bers engine occupies 761 square re
md weighs only 10000 pounds,
ons AO7 pounds per square foot, apo
kwo thirds as much per square 10
aay las the Snow engine. The Allis-Chf
mers engine has the fly-wheei
and one extreme end of he engine al
Ica- the load at the other end. The d
wd- lance from the main shaft to the II
AVID wheel to the center of the plung
iii of the pump is 80 feet.

,uhd near the center of the engine and |

lIirv t~ernately a pull and a push upon
