SIDE VIEW OF CHAIN CULTIVATION.
ground during warm days runs con-
siderably higher than at a few feet
above the surface.
For instance, 1t was found that when
. the temperature was 100 degrees f. in
the regular weather bureau shelter
about four feet above the ground the
thermometer registered 40 degrees f..
on the surface. Likewise 90 degrees
+. in the shelter was accompanied by
120 degrees f. on the ground and IS
degrees E. in the shelter by ITO degrees
F. on the ground.
1t is not surprising, therefore, that
] the cotton squares that fall to the
ground and are not shaded are very
quickly baked, so that the weevils per-
ish, if not from heat, then from the
hardening of the food supply. In most
cases they are simply roasted, their
bodies assuming the appearance Of
larvae that have been placed in a

Chain Cultivator Devised.
When the foregoing facts came to
lSuL chOItS WcIc luuut " PcIlcCL d
device that would bring the infested
squares out of the shade of the plants
to the middles Of the rows. After
much experimental work one Of the
writer's former associates, DR.. w. E.
Kinds, devised an implement that ac-
complishes the desired work in q sat
isfactory manner This implement is
ho oh IN, low hot
drag.
The following specifications should
enable any. blacksmith to construct an
effective chain cultivator:
The draft bar m, made of one-half
by five-sixteenths inch tire steel, about
fifty-two inches long, is designed to be
about sixteen inches above the ground,
and this is the height of the rear arch
h m, which is of this size and form
to allow old cotton roots, etc.. to pass
through freely without clogging at the
rear.
LOG Chains" Used.
The distance between the rear ends
of the chains G, +, is in each pair
fixed at about ten inches. The dis
lance between a chain of one pair and
that Of the other at their front ends
should be about nine inches. The
chains used are of the size known as
'log chains" having short, close links
of three-eighths inch iron. This style of
chain can be cut to the length needed
in each case. The chain is easily at
tached by simply making the hooks at
d, e. ( and so that the end Of the
hook is as wide as will pass through
the length of the link and narrow
enough at the middle of the bend to
allow the link to turn and bag the
other way. So long as the chains are
kept tight they cannot become unlock
ed. The hooks should also be turned
or faced in such a way that they will
not be likely to catch the passing
plants or rubbish.
cIevis Is Adjustable.
The clevis o p is simply hinged, so
that there will be no tendency to pull
the front of the machine off of the
ground, and it is also broad enough in
front to allow of the point Of draft be-
ing moved from one side to the other,
SO that the front of the machine may
be thrown closer to one row IL desired.
The front guard on each side, b
d, is made of one piece Of spring
steel seven-eighths by three-sixteenths
of an inch. This size seems sufficient
ly strong and best adapted to carry
the tension of the chains d 8 while
still yielding to the pressure against
the bases of the plants as they may
strike the outer sloping ends near d.
The inner ends of these guards b
are horizontal, about eighteen inches
each in length, and serve to carry the
front guard above the draft bar n m
and. passing through the keeper q.
