Wherever there are any indications OF

Answered and . / cannot answer
these questions. because I do not know
what is meant by nitrate soluble 1t
is rather meaningless expression, not
known to the trade nor to the nomen-
clature of official inspection and ANALYSIS.
Aside from the nitrate soluble, what
ever that Is. the fertilizer Is n simple
I acid phosphate. containing 70 per cent
soluble On water and per cent re-
verified Soluble in acid. or a total Of L
per cent available phosphorc acid Alone
IT Is not a suitable fertilizer for either
corn or cotton and should have some
potash to fit it for peanuts.

56-40" 1t is not uncommon Tor some

sum total of the different percentages OIL
phosphoric acid together with the lme
with which il is in chemical union. J
have always suspected that it is a FORM
of mild fraud intended to mislead the
purcha ser to the conclusion that lhe
percentage of bone phosphate Is some
thing additional to the phoSphorlc acld.
