hound, bears hgeipst the, OM, bo as shown in
Fig. 1 of the engravng, ad forms the groove
before mentioned.  2hroa  forward, as sees.
in Fig. 2, it carries the arm with it, thus open-
ing the groove and permlttiig the forks to fall
forward and fold up. By this means It is, while
advancing, set to work or th'rown out of the
ground at will, by a simple movement of the
hand, and is perfectly under control of any
one old enough to drive the team.
  The engraving represents an implement
working three feet in width, and a depth of six
to eight inches. Whentoldeditmay be drawn
about on the farm or common roads without
injury to its parts.
  Patents for this invention were procured
February 26th, 1861, and May 18th, 1862, by
C. Comstock, of Milwaukee, Wis., and the im -
plements are now being manufactured at that
place.

        Chloride of LId.-A Query.
  DzAx Sin:-I have noticed with pleasure
that the FARXMR gains friends. If the FARM-
si could be transformed into a weekly paper,
I think it would replace nearly every other
paper and be welcomed at every fireside of the
farming community.
  One question I would like to ask: Chloride
of lime has been recommended as an agent to
hasten 'germination, also as a preventative
against insects, and lately I have seen it stated
that it was used in Paris instead of water to
keep the dust down in the streets. The latter
use would suggest that it may be produced
very cheap. You would confer a favor on me,
if you would explain to us what is Chloride of
lime. Can the tarmer produce it himself, oi
has he to depend on the druggist for it? and
if so, at what price can it be obtained?

  [Chloride of Lime is the product of the
combination of common lime with chlorine, a



veensh ga obtained by the decomposition of
,omoWPt, which is the chloride cf aOdium.
In soda-ash works there is a waste product
known as hydrochloric acid, and consisting of
ahlorin. and hydrogen. This acid, when heat-
Bd with b40oxds of mang anese, yields up the
gaseous chlorine; sad in order to manufacture
chioride of lime, it is simply necessary to
spread fresh slaked lime upon shelves in leaden
or stone chambers and expose it to the action
of the chlorine thus obtained. The lime ab-
sorbs the gas, and is then put up in tight box-
es or casks for sle. If it is desired to use it
in liquid form, the powder must be dissolved
in water. Price at the druggists 11 cents per
pound.-EDITOR.]



   ED U CAT IO NA L.

   The State Univerdty-A Step Forward.
   Hitherto the Wisconsin State University has
not had a very prosperous career. As to grade
and quality it has ranked with the best colleges
in the West, but financially, and as to that pop-
ularity which secures a large attendance, it
has fallen far short of the high mark which its
friends set for it at the date of incorporation.
  As it appears to ns, this partial failure is
due to three principal causes:
  1. The absence of the best possible financial
management, as evidenced in large and need-
less expenditures for buildings.
  2. A persistent disregard, on the part of the
Regents of the University, of the rights of one
entire half of the youth of the State.
  3. A narrow, illiberal and, unjust policy on
the part of the State.
  The first of these evils is now beyond the
power of correction: the second is in process
of correction, and the third, it is believed, will
not much longer remain a reproach to the State.
  Section 2 of the Act of Incorporation reads
as follows:  "The object of the University
shall be to provide the inhabitants of this State
with the meas of aequiring a thorough knowl-
edge of the varions branches of literature,
science and the arts."
