An BrPoRrAST Invention Eoa THE SrarR oP
LouIsIASA.-A machine intended for dredging and
for removing earth under various circumstances bv
the application Of steam mower upon the action Of
the Arehimedean screw. and not confined To n reru.
lar Depth but can be varied in tf action 20 the entb
required. A model Of this invention "a now on ex
hibtion by the inventor Mr.. Richard Montgomery al
the office of Elliott Robbins a. Co.. marble buildinps
No. 80 Carondelet street.
This machine has been submitted to the critical ex
animation of some of the most able minds of this
country as well as Europe and il no longer an ex
pertinent as il has been tried and met with unparal
leed success in its operations and one Of which is
now under construction to show its action 10 the et
zens of Louisiana
The dgantages TO this State with its millions of
acres Of rich alluvion, now remaining dormant for
the want Of proper drainage is incacuable and par
ticulary to the back portions of the lands of this
city extending to the lake, in the drainage of its
sagnant waters and bringing them into use for culti
vation and building purposes For ordinary planta-
ton dtching the screw of the machine (the priuci.
pie upon which it works) being enclosed in cylin-
der to the side of wheeled carriage TO which IL ia
joined would be 10 feet 10 inches in length and feet
in diameter The quantity of earth cut by each rev.
oution of the cylinder, which revolyes twenty times
in a minute would be feet in length and z feet
wide. The screw under headway being filled half
full of earth ioned with the yzoi,bt of ,ha oIis
