SOME LEADING AUTHORITIES ON THE MAPES MANURES. 
“The Mapes fertilizers, though higher in price than some others, are scientifi- 
cally, carefully ancl honestly made. In the use of them we arc always pretty 
sure of good results. We use them every year and have not been disappointed 
in their action, (May, 1888). They seem to go right to the spot and stay there 
better than any other sort we have used. We get most excellent results in both 
corn and potatoes.” (Nov., 1888).— Wilmer Atkinson. Farm Journal. 
“ 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 is certainly as good a fertilizer for the Crops as 
we can expect to find.”—/. T. Lovett. Orchard and Garden. 
.“Its action Approaches Certainty, or as near it as any manure can he ex- 
pected to do.” — E. S. Carman , Rural New Yorlcer. 
“ Our own experience with various commercial fertilizers has convinced us 
that with judicious use of the Mapes Manures worn out lands can be Rest red 
to Fertility Quicker and with less expense, than in any other way.” 
“The remarkable success which has attended the Mapes fertilizers has given 
them an enviable reputation and standing, not only in the United States and 
Provinces, but in Great Britain and other European countries.” — American 
Agriculturist. 
“ Mr. Mapes has studied industriously and has worked conscientiously to help 
the farmers. I believe he has tried as hard to serve the farmer's true interests 
as any one in this room. He knows how to make good fertilizers adapted to 
their needs, and he is making as good ones as he knows how to make. They are 
reliable and may be depended upon. You may be sure of getting what you buy — 
getting what is guaranteed. I am glad to stand here and authoritatively make 
these statements.” — Prof. George H. Cook. Director of the New Jersey 
State Agricultural Station, at a meeting of the State Board of Agriculture, 
at Trenton, N. J.
