THE RURAL NEW-YORKER. 
As to the quality of their goods, the Mapes Formula and Peruvian Guano Company analyses show them to be unexcelled for farm, fruit or garden 
s. The analyses of 01 nitrogenous superphosphates and 70 special manures by the Connecticut State Experiment Station, show that the Mapes heads 
r in both ci ,asses in being found to have the highest valuation compared to the cost to the farmer. —N. E. Homestead, March 8. 1894.

ANALYSES. 
Eight to nine bags (200 pounds each) 
of the Mapes Matures contain more 
pounds of the valuable plant-food ingre¬ 
dients, namely, ammonia, phosphoric 
acid and potash, and all in the choicest 
forms, than 10 bags (200 pounds each) 
or one ton of other leading brands. 
SUPERIOR FORMS OF PLANT FOOD IN THE MAPES. 
The Mapes Manures excel all the leading competitors in the reports of the 
Connecticut State Agricultural Experiment Station for 1894 and 1895. It is well 
known thaj the phosphoric acid in a mixed fertilizer, the insoluble as well as the 
soluble ar j? vailable, is valued by the same schedule of values, whether the same 
be deriv^o 7 from rock or from bone and PERUVIAN guano, as the chemist cannot 
detect difference when in a mixed fertilizer. In the Mapes fertilizers, all the 
phosj^Hric acid is from bone and Peruvian guano, and gets the benefit of NO 
hig i valuation than if it were from rock, yet the phosphoric acid in bone and 
pi vl an guano, particularly the insoluble, is worth both commercially and 
culturally several times as much. 
The users of Rock and of inferior forms of Nitrogen have every reason to be more 
than satisfied with the present system of valuation. Their goods are overvalued.

Art nonoraoie KvCOril* unfailing good results, we are glad to note the enviable record which these fertilizers have made at the 
Connecticut Experiment Station. In the Station Record, recently published, the analyses of 61

(Extracts from the last Official Annual Report. 1895, of the Connecticut State Agricultural Station.) 
The average cost of the nitrogenous superphosphates is 832.93; the average valuation is $23.30, and the percentage difference 41.3 per cent. 
These valuations, it must be remembered, are based on the assumption that the nitrogen, phosphoric acid and potash in each fertilizer are readily available to farm crops. Chemical 
examination can show pretty conclusively whether this is true in respect of potash. There is less certainty regarding phosphoric acid, while the chemical examination, as it is usually made, 
gives little or no clue as to the availability of the organic nitrogen of mixed goods. 
SPECIAL MANURES. 53 Brands. Page 54. 
The average cost per ton of the Special Manures has been $38.13; the average valuation $28.62, and the percentage difference 33.2 per cent. 
Of the sixty brands of Special Manures analyzed, twenty-six are quite below the manufacturer’s minimum guarantee in respect of one ingredient, four are below in respect of two 
ingredients, and one in respect of all three ingredients. Fully one-half, therefore, are below the manufacturer’s guarantee. 
The average cost per ton of the seven home mixtures, including cost of mixing, is $36.76; the average valuation is $31.70 per ton, and the percentage of difference between cost and valua¬ 
tion is 16 per cent. In factory-mixed fertilizers this percentage difference has been on the average 41.3 for Nitrogenous Superphosphates, and 3?.2 for Special Manures during the last season. 
The average valuation of these home mixtures is, therefore, very much nearer their cost price than is the case with factory-mixed goods. 
It will readily be seen from the above summary of the figures in the Connecticut Station Reports for 1895, that the Mapes brands are not only much 
cheaper to the farmer than the other manufactured fertilizers, and have been found by the Station to have a much higher valuation as compared to the cost 
to the farmer, but approach very closely to the figures given by the Station to the home mixtures—mere crude mixtures of raw materials. In the case of 
the Mapes Manures, as has been said by those who have studied their manufacture at the works, “ the point where the home mixer leaves oft' is the point 
where the most valuable process in the manufacture of the Mapes goods begins.” In these goods there is the advantage not only in the selection of the best 
materials for the wants of the crops and for promoting the best chemical action in the mixture, but also the advantage of fine grinding, and the action of 
seasoning during extended periods and other processes during wdiich the ingredients become perfectly blended, and the fertilizer homogeneous in texture, 
and present in the soil to the fine rootlets of the growing crop a true plant food, instead of, as is the case of the home mixtures, streaks and lumps of 
chemicals and crude raw materials. The importance of this perfect blending of all the plant-food ingredients as found in its perfection in Peruvian Guano, 
has been repeatedly recognized by the leading agricultural authorities. 
In the above summary the Mapes brands are found to average in cheapness very near to the home mixtures, and in some cases the Mapes brands are 
found in the reports to figure considerably better than even the best crude home mixtures. 
In the figuring by the Station on the manufactured goods, it should not be forgotten that all brands are included, and that if the Mapes brands were 
omitted, the average of the remaining brands would make a correspondingly lower showing. 
The percentage difference between cost and valuation in the Mapes goods is seen by the reports to be on the average about one-half as compared w r ith 
the average of all manufactured goods.
