BOWKER'S ♦ 
A§:ricultural Chemicals and Raw Materials, 
FOR MIXING FERTILIZERS AT HOME. 
i^^^Ji^TATION tests and field results both show that Bowker's Fertilizers are economical to use: that many of them are actually 
|^«^^^^ " double strength," containing twice as much plant-food in forms best adapted to different crops ; and that they may be relied upon 
^ to do all that such high-grade fertilizers may do. 
i^^^cl For various reasons, however, some farmers prefer to mix their fertilizer at home. To all such we are prepared to furnish the 
materials at the lowest market rates. 
We have a capital of one million dollars invested by substantial business men for the purpose of carrying on the fertilizer business legiti- 
mately in the most approved manner. Our factories are equipped with special grinding and mixing machinery; our acid plant, recently 
enlarged and perfected, is claimed by experts who have visited it to be the best in the country. We handle an average of loo tons of fertilizer, 
or fertihzer material, every working day in the year ; and we have found no order too large for us to handle, nor is any too small to receive 
careful attention. If a farmer desires advice, or to consult about any special formula, we shall be glad to give the benefit of our experience. 
We guarantee the chemicals offered below to be of the full strength represented.
