aud on last Saturday, IN addition 10 =
large company from the neighborhood. an
excursion from Philadelphia assembled At
tic works aad entered into an investiga-
,ipn Of the pump itself. The power applied,
| aud the work being done. Some Of your
readers have. no doubt. heard through |
the Philadelphia papers Of the conclusions
rtnched by these gentlemen. They came
by inyitation Of l,urton II. jerks. the
maker Of Shaw's Propeller Pump" and
numbered 35 to 40 persons, among whom
we're Thomas Shaw. the inventor. II. p.
Berkcubiuc, the well-kpown Hydraulic
Engineer. Joseph Mitchell, the President

and mnny others well known in financial
| and merchanical circles. After spending
/ so hours they returned to the PHO, Bob
and on popping champagne to the honor
u Delaware and the gentlemen who had
extended them the courlcsies Of the oc-
chsion they started at I p. NJ. for pbila.

Next, comes The lst section Of the pump.

contains two propeller wheels with two
wings or arms each aud one stationary

described as propeller wheel which does
not revolvc its angle being different from

rcvolvc with spindle or shaft dropped
through the centre of the cylinder Then
