RELATIVE CHEAPNESS OF HIGH AND LOW PRICED FERTILIZERS 
The official reports of the Connecticut Experiment Station for 1906, 1905 and 
1904 contain the analyses of some eight hundred samples of brands of mixed fertili¬ 
zers (samples taken in the market). In these reports of analyses the MAPES MA¬ 
NURES are given the highest valuation of all and on the ordinary basis of figuring 
“valuations,’ no benefit is received by the MAPES MANURES for the superior 
and more costly forms of Potash, as Nitrate of Potash and Carbonate of Potashfeight 
cents instead of five cents per lb.), nor of the superior forms in Peruvian Guano, 
Pure Animal Bone Flour, of Nitrogen, Ammonia, Phosphoric Acid, Potash, etc.

"As a Rule Fertilizers Which Sell at a Low Price Are Really the Most Costly.” 
Page 55, Connecticut Station Report for 1905: 
“As a rule, fertilizers which sell at a low price are really the most costly if we regard the amount of plant 
food in them. 
feome brands of fertilizers sold in Connecticut by reputable manufacturers, and freely bought by some farmers 
supply scarcely more than one-third of the plant food which can he bought for the same amount of money in other 
brands which are sold in the same places. That is, in buying these brands, the farmer is simply throwing away two- 
thirds of his purchase money.” 
The MAPES MANURES in this Connecticut Station Report, 1905 , also for 1904 , are given the highest valua¬ 
tion of all mixed fertilizers, samples taken in the market, on the ordinary basis of figuring “valuations.” 
The American Agriculturist, Orange Judd Co., in reviewing this report for 1905 , states: 
The Connecticut Agricultural State Report again confirms what we have so often urged—that the cheaper the 
price per ton of a commercial fertilizer, the higher the cost per pound of the actual Nitrogen, Potash and Phosphoric 
Acid it contains. Accordingly, it is not surprising that Dr. Jenkins contends some farmers are not getting the 
benefit from fertilizers that they might, because they go for cheapness instead of quality.” 
“ Exactly .600 commercial fertilizers and waste products have been analyzed and tabulated.” 
“VALUATION” OF FERTILIZERS 
They Fail to Determine the Quality of Goods. Established Reputation the Main Security to the Purchaser. 
Extracts from Animal Report of the Connecticut Agricultural Experiment Station, Prof. S. W. Johnson, 
Director, for year 1895. Issued December, 1895. 
“Ihe 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 to potash. There is less certainty regarding phosphoric acid, while chemical examina¬ 
tion, as is usually made, gives little or no clue as to the availability of the organic nitrogen of mixed goods.” 
“While various inferior or agriculturally worthless forms of nitrogen are in the market, the main security of 
purchasers of mixed fertilizers is in dealing with firms which have an established reputation, and in avoiding ‘cheap’ 
goods offered by irresponsible parties.”—Page 39.
