organic dctritus. 1t also forms some
sulphatc of ammonia and carbonate of
lime. There is no doubt of the cnor-
nous quantity of sulphuric acid which
vegetation requires and which plaster
can furnish it. The proportion Of
sulphuric acid in n crop of luccrnc and
rape goes as high sometimes as 33 to ID
pounds per acre. In cabbage it goes
up TO l76 pounds per acre. Burnt

At n temperature of 100 degrees it

the ability to rcabSorb water if added

turing or for agriculture. 1t contains
80 per cent. of sulphuric and Al per

Lime is the cheapest term OF the COM
plctc fertilizer.
Pulverizcd %anhydrous plaster should
always enter to a slight excess in
chemical fertilizers where it acts sew
eral useful parts. 1t is a fertilizer
and IN cXcipicnt. 1t helps to improve
The soil, gives the necessary volume
to the fertilizer and makes it easier to
handle.
We sec that tho four agents of fer
tility, nitrogen, phosphoric acid, potash
and lime, exist in ineXhaustiblo guam
titles on the globe and can always be
got at. When you have got the first
ingredients of a fertilizer, the prcpar-
ing is simple mixture based upon the
nature OF the culture in view. The
fertilizer holds the active principles Of
the substances composing it.

On adry, tight and smooth barn floor

plaster, then the sulphatc of ammonia,

arc machines costing from $ll0 to $3.50
which do all this work at once ana in
large masses.
TIE OFFICE OF WATER.
The surface Of tho globe is composed
| Of two couchcs or layerS-onc melted,
the other crystallizcd. In the melted
couche the lime, iron, soda and potash
are all combined with SILICA and con.
gcalcd in blocks. This is chaos and
inertia. In tho crystallizcd couchc
there is sediment; water has jntcrvcn
cd; there has been a separation of Ger
| tain bodies and a reunion ofothcrs. u
| rudimentary chemical fertilizer has
| formed naturally and become tho
| theatre Of the first manifestations OF
vcgctal life.

which cnvclopcd the earth, and which
later was to form air and water, WAS
held off at n great distance and very
much dilated by the high temperature
of the central neuclcus. Water wa.

In this way seas and continents were
formed. Solar radiations crossed the
layers of the atmosphere where they

Just as they are now, were carried
across continents to be dissolved al

washing it down. 1t disintegrated the
crests of mountains, furrowcd their

lime. Potash and soda, and mixing al.
these agents with the powdered debris
it carried down, composed the arabic
soils of the valleys. Fertility wa.
