WE HAVE LATELY SECURED THE AGENCY FOE THE MEXICAN PHOSPHATE AND SULPHUR 
COMPANY, MANUFACTURERS OF SUPERPHOSPHATE FERTILIZERS FROM GENUINE 
GUANO OR PHOSPHATES IMPORTED PROM GULF OF CALIFORNIA AND 
COAST OF MEXICO. 
"He that maketh 2 blades of grass grow where but one grew before is a benefactor of mankind." 
The Mexican Phosphate and Sulphur Company are the owners, under concession from the Mexican Government 
of deposits of Guano in the Gulf of California, and are engaged in shipping same to Europe, where it finds ready sale 
and lias already taken front rank in the market. Over ti50,009 worth of raw phosphates have been shipped, and de- 
mand is increasing, 
Beiieving that the same might be introduced and used with profit by the onltivators of the toil in California, tlie 
eompany has commenced the manufacture of Nitrogenous Superphosphates at Sobrante Station, on the line of the 
Central and Southern Pacific Railroad, from Guano, imported from its deposits, and now ofier to the public a gonuine 
article iu the way of a fertilizer tor farms, orchards, vineyards, gardens of all kinds, such as has never been offered in 
California before. 
A sample of this fertilizer has been submitted to Prof. K. W. Hilgard of the College of Agriculture in the Univer- 
sity of California, with the following results: 
Dmivehsitt of California, November S, 1886. 
DR. J. KOEBIG: 
Dear Sir:— I have analyzed your sample of “Nitrogenous Super Phospate,” with the following result: 
Soluble Phosphoric Acid 12.90 per cent. 
Reverted Phosphoric Acid 95 “ 
Insoluble Phosporic Acid 2.®J “ 
Pota.sli 2.23 “ 
Ammonia 1.87 “ 
Nitric Acid 2.95 “ 
The above amount of Nitric Acid is equal to 0.85 per cent. Ammonia, therefore total of Nitrogen calculated as 
Ammonia, 2.72 percent. 
This fertilizer is a valuable manure for vineyards, orchards, gardens, farms, and 1 recommend its use by the culti- 
vators ot the soil generally in California, Yours truly,

DR. J. KOEBIG, San Francisco. 
Dear Sir:— I take pleasure in adding my testimony to that of Dr. Schneider as to the high quality of the “Nitro- 
genous Phosphate” fertilizer, analyzed by him at your request. It is a high grade article, and as such returns the u.«cr 
a better money value than a low grade fertilizer. It is especially well adapted to use in Culifornia, on account of the 
predoininence in it of Phosphoric Acid, which is generally in siiinil supply in our soils. Yet it is desirable that com- 
plete fertilizers be used in our orchards and vineyards and yours is of that character in furnishing Potash and Nitrogen 
as wc'.l. Very Respectfully. E. w. HILGARD. 
The value of this Fertilizer consists in the large percentage it contains of Phosphoric Acid— the chief element of 
all plant food— in combination with the necessary quantities of Potash and Ammonia, and the ease and cheapuess 
with which it can be applied. 
In ordinary soils the following quantities will be found sufficient: 
For Wheat, Barley, Corn and Oats, 300 to 850 pounds per acre. 
For Grass, Sugar Beets and Vegetables, 250 to 300 per acre. 
For Young Vines, Fruit Trees, from i pound to 1 pound each. 
For Old Vines, Fruit Trees, from 2 pounds to 5 pounds each. 
. . , .I'otf'lower Gardens, Lawns, House Plants, etc., a light top dressing, applied at any time, will be found 
verj beneficial. 
It is not claimed that this fertilizer is an absolute cure for Phylloxera, or the oiher evils which are incident to the 
cultivation of the soil; but it is confidently asserted that by enriching the soil and supplying the needs of plants they 
attain greater growth and are better able to withstand the attack of either animal pests or inclement seasons. This 
fertilizer is introduced to the people of California for this purpose and a critical test of its merits invited. 
On our own and very poor land around the factory, at Sobrante Station, we sowed barley and oats- one-half of 
each was fertilized with 250 lbs. to the acre, as an experiment.
