Extract from letter of March 1 , 1895, from Edward F. Dibble 
Seed Company.) 
The Mapes Potato Manure was used this year on our trial 
grounds with wonderful results. I send you cut of our 
•• Trial Ground ”, cut of “ Irish Daisies”, and cut of “ Money 
Maker” potatoes, all of which were grown upon the Mapes 
Potato Manure purchased from you. On our Trial Grounds 
we had 4% acres containing 207 different kinds of potatoes : 
early, intermediate and late, some good yielders and some 
very light ones, of course, on which we planted but 13 bush¬ 
els of seed, and from the 13 bushels of seed, by using the 
Mapes fertilizers, 000 to 1,000 pounds per acre, we obtained a 
yield of 877 bushels. There was no fancy culture whatso¬ 
ever on the potatoes. The different kinds were all cut to 
one eye, by one man. and planted one piece in the hill two 
feet nine inches apart each way. 
“MONEY MAKER” POTATOES. 
The field of Money Makers shows the most luxuriant 
growth of tops of any variety of potatoes that we have ever 
seen growing, and it has been our pleasure as potato growers 
to inspect over 250 varieties of potatoes and at their best. 
We had Money Makers that yielded us, in field culture, 
over 400 bushels per acre, fertilized with 1.000 pounds of 
your Potato Manure. 
“ Some 15 years’ experience with the Mapes Potato Manure. Season 
1894: Yield, 1,950 bushels on 6% acres; on 1 % acre (the best piece), yield 
was 442 bushels. Began using: the Mapes Potato Manure about 1880, and 
since 1887 have used it for potatoes every year, raising; from 5 to 11 acres 
per year. There seems to be something: about the Mapes Potato Manure 
that seems to just suit the growing crop.” 
LEROY BROWN, South Windsor, Conn. 
I ship to-day two boxes of potatoes (one bushel each) containing the 
product of 26 hills, manured with 1,200 pounds (six bags) of Mapes Potato 
Manure per acre, the other containing the product of 56 hills, from rows 
adjoining, five of which were left without the Mapes, for comparison.”

“ Our exhibit at the World’s Fair at Chicago would have been a 
failure if we had not used the Mapes Potato Manure.—CHAPMAN & HILL.

“ Under average conditions, and in far the greater number of cases, 
we do not hesitate to name the Mapes Potato Manure as the best and 
most profitable fertilizer for potatoes.”—American Agriculturist. 
The Mapes Potato Manure.—” Its action approaches certainty, or as 
near to it as any manure can be expected to do.” 
E. S. CARMAN, The Rural New-Yorker. 
“The Mapes Manures give surprising resxilts, and we believe the 
reason is, that the ingredients are mixed with brains.” 
WILMER ATKINSON, Farm Journal. 
“ Our own experience with various commercial fertilizers has convincedaus that with 
judicious use of the Mapes Manures worn-out lands can be restored to fertility quicker, and 
with less expense, than in any other way.”—American Agriculturist. 
MONEY MAKER GROWN BY THE 
EDWARD F. DIBBLE SEED CO 
“ We have been using the Mapes Potato Manure for eight years, indeed we do not care to 
use anything else for potatoes, and have never been disappointed yet. We do not have scabby 
potatoes as we used to with stable manure.”—WILMER ATKINSON, Farm Journal, M’ch ’95. 
“ Having used various brands of Mapes’s Manxxres on oxxr own farm and garden for the past 25 years with 
A I—I o |-% 1 £x unfailing good results, we are glad to note the enviable record which these fertilizers have made at the 
4 a 11 M I 11G1 11 Connecticut Experiment Station. In the Station Record, recently published, the analyses of 61 nitrogenous 
superphosphates, and 76 special manures show that Mapes’s heads the list in both classes. Compared with 
the cost to the farmer, these fei-tilizers have been found to have the highest valuation. American 
I\yvU I Cl • Agriculturist, April, 1894. 
The Mapes Fertilizers head both Lists of Fertilizers Reported by the 
Connecticut Experiment Station 
“ It will be difficult for the careful and unprejudiced reader of the Experiment Station reports, not to be impressed with the remarkably high standard 
maintained by all the mapes goods. In Part I., lately issued, of the Connecticut Station Report for 1893, the analyses of til ‘nitrogenous supei- 
phosphates’ and 76 ‘special manures’ show that Mapes heads the list in both classes in being found to have the highest valuation, as figured by the 
Station, as compared with the cost to the farmer.”—Connecticut Farmer, Hartford, March 3, 1894. 
“ 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 
purposes. The analyses of 61 nitrogenous superphosphates and 76 special manures by the Connecticut State Experiment Station, show that the Mapes 
HEADS THE list in both classes in being found to have the HIGHEST valuation compared TO THE cost to the farmer.”—N. E. Homestead, March 8, 1894. 
The last published report of the Pennsylvania State Board of Agr^ture, containing official analyses and valuations by Dr. William Freer, Chemist 
of the Board and of the State College Experiment Station. State Cgige P. O., Pa., shows that to August 1, 1894, of the 5(5 brands of Potato Manures 
analyzed and valued in this report, ^ ^ potatQ M A feeds 33 brands by *10.00 to *30.00 per ton. 
The Mapes Potato Marexceeds 21 brands by 5.00 to 10.00 per ton. 
The Mapes Potato M^ure exceeds 7 brands by 3.00 to 5.00 per ton.

THE MAPES MANURES FOUND TO BE THE ONLY ONES TO EQUAL OR EXCEED THEIR GUARANTEED STRENGTH IN EVERY CASE. 
Of the manufacturers whose goods were examined by the Rhode Island Experiment Station, and reported on page 132 of Bulletin No. 26, November, 
1893, the Mapes Company was the only one of all those whose tests amounted to 12 or over, who were found to equal or exceed their guarantee in every case. The 
Mapes Company had a record of 100 per cent; the next best record was 93 per cent.
