INDUSTRIAL INTELLIGENCE.


TIE BYsr CoRs PLAsfER.-We have examined
the model Of Corn Planter invented by Mr.. Luciu'
Thompson OF New Haven Conn and put in use during
the past Spring which seems to be the most efficient
machine for this purpose yet in existence. 1t IS
mounted on two light wheels, and is worked by a
horse with the aid of one boy who sits on the
box holding the reins. great fanlt with Corn
Planters genersly-on which, by the way, there are
.ome fifty or paients-is leaving the earth loose
instead Of nicely covering and pressing down like
farmers hoe; another is that the grains are planted
too closely together; but both these are avoided in
the machine referred to, aud the labor OF planting
which is always cool and less severe than most agr
cultural Opt raons is by this means rendered decidedly
easy and pleasant Two rows are planted at once, the
earth for each being excavated by light plO wlike
attachment and replaced by nearly similar scrapes,
standiug il reverse position, while behind the whole
are dragged metallic rollers of suitable weight to press
the earth together aid form q smooth surface. The
pows are dragged continuously along, and have no
motor except the ability to yield in case of meeting
too great On obstruction. Tdere are no recprocatng
paris 10 get cut Of erder except single valve IN each
spout which regulates the precise moment of deposit
ing the grain in the shallow funOw. The proper
amount for each hill is measured off by continuous
rotary motion thrown down into wide spout and held
near its mouth until the right moment, when 1t is
dropped behind the forward pow covered by the sue
ceeoing ones and pressed down by the roller stOpn
reach of the driver throws the small measuring wnee
out Of gear while the machine turning round at the
ends Of the rows and strong lever in the hand

any formidable obstruction is anticipated Altogether
the machine is by far the most complete of any which
has yet appeared, and is worthy the immediate atten
tion Of those in the West, or elsewhere, who con-
duct agricultural operations on scale of any consid
cradle magnitude.
