SOUTHERN PL A.NTER. — ADVERTISING SHEET. 



OCTOBER, I860. 



Attempts having' been made, recently, to depreciate the enviable character of SOMBRERO 

 GUANO as a fertilizer, by partisan and untruthful publications, the Proprietors beg lea veto submit 

 to the Agricultural community, the annexed portion of a letter from the mosi authentic chemical 

 source in the United States, setting forth the REAL facts of the case upon the only reliable basis, 

 that of an analytical examination of the several Phosphatic Guanos in Commerce. The dara 

 obtained by Dr. Morfit are incontrovertible, and not only attest the superiority of SOMBRERO 

 GUANO, as the richest and* iriost efficient Phosphatic Manure, but are suggestive also of the 

 futility of any attempt to bring the Navassa or other similar Guano into successful competition 

 with it. Orders received bv ' ROSS W. WOOD & SON, New York,

 NEW YORK, 2 1st March, 1860. $ 



Messrs. Patten & Miller, and 



E. C. Wade & Co., Savannah, Georgia: 

 Gentlemen — In reply to your joint letter of 9th February, requesting my professional opinion 

 upon certain points of Agricultural interest, and which more immediately concern you as honor- 

 able dealers in Fertilizers, I have given the subject its due consideration, and now submit my 

 report. 



1. Your first question, as to the rank which belongs, properly, to SOMBRERO GUANO, com- 

 pared with the Phosphatic Guanos from Navaza, Jarvis and Baker's Islands, will be best an- 

 swered by the annexed table, which shows their relative composition. Baker's Island Guano 

 is omitted, however, from the comparison, for the just reason, that no cargo has been imported, 

 it being known here,- at this time, only by sample.
