Guano exceIIed by DE BURG

TT is settled point with all Chemists and
Il scientific Farmers, that Peruvian or any
other description of guano does not supply to
the soil one-third of the necessary constituents
for the growth of all crops, on all soils; and
the ANALYSIS of wheat, rye, corn, oats. potatoes,
tobacco, etc, prove the fact. Every one who
has had any experience in the use of ouano
knows that the land becomes exhausted and
IMPOVERISHED by its continued application.
Many experiments have been made recently,
relative to its value as compared with the best
Peruvian Guano, and preference given 10 il
as a manure. being quite as effective in its
action of inducing early maturity as guano.
but much more durable and terrifying TO the
soil. and less volatile.
To the Tobacco Planters il will be found
very beneficial. Tobacco contains large
amount Of mineral matter, which is being con
tinually removed by the plant in solution, and
It is but reasonable to suppose that the soil
must soon become exhausted OF minerals, If
none are returned as a manure; the supply Of
such deficiency may be found in the applca-
ton of De Burg, it being the means Of pro-
ducng great rapiditv of growth during the
first stages of the plant. CARRYING it out OF the
reach of the ravages of the fly, and inducing
early maturity. II should be used at the rate
of 9 to 3 cwt. to the acre-should be broadcast
or applied in the hill, where from its chemical
composition and dcliquescent nature, it attracts
considerable moisture ana the plants VIII De
less liable to suffer from drought.
Dr. DAVID STEW AltT, Professor OF chem
istry at 81. johns college, Annapolis Nd,

raj ciety-analyzes eyery.lot OF DC Burg we
receive, ana says, IN his report to us;
"De Burg compound is much more general
" valuable to the practical farmer than any
mixture OF phosphates and ammonia or manp-
ulated guano. There are other elements in De
Burg to which attach as much Importance as
ammonia and phosphates, and ! cannot pass a
cargo where one Of these is absent, however
much ammonia ana phosphates are present"
Again he says - Peruvian Guano, Hickory
Ashes, and Super-phosphate of Lime, separate
~ applied to land, exhausts it, las general
rulc) upon the principles established by Laws
and Pussy, in n series Of years experiments.
Ny experience in their use separately, in con-
trast with their combined influence, gives Inc
an assurance in recommending compounds to
all farmers, that prefer the common sense, or
empirical mode, to any special manure. In
| other words, "A compound like De Burgs, is
more valuable than any one Of its elements
which might separately sell for seven times the
cost Of the compound, unless we know that we
need one element only, and have an incxhaust-
| IDLE supply of all the rest"
