is in dimensions about three by fourteen miles, and the assays show 

 about four per cent of potash in the clay and water menstruum at a 

 depth of twenty feet." 



Kelp, a seaweed that grows abundantly in the shore waters off the 

 coast of California, is rich in potash, and the ash of sage brush contains 

 a high per cent of potassium salts. Judging from what has been accom- 

 plished during the past two years, it is reasonable to assume that the 

 United States will very soon be independent of Germany in securing a 

 supply of potash. 



If commercial fertilizers are applied to land devoid of humus, the re- 

 sults will be very disappointing. Barnyard manures thoroughly dis- 

 tributed throughout the seed bed cause commercial fertilizers to be 

 more effective and more lasting. If commercial fertilizers are used in a 

 careless, haphazard way, they are not profitable. If, however, they are 

 utilized scientifically and the right methods of farming are pursued, they 

 are very profitable. 



If the farmer will gi'ow legumes, utilize barnyard manure, rotate his 

 crops, and supply in a commercial form enough of any element or 

 elements to give his crop a full balanced ration, he will be richly re- 

 warded. 



Our leading manufacturers of fertilizers are attempting to educate 

 farmers how to use their products to the best advantage, and in doing 

 that, they should receive the support of all who are interested in pro- 

 ducing more per acre and at the same time maintain the fertility of the 

 soil. In ordering fertilizer, the farmer should state for what crop it is 

 intended, and give a fair description of the character of his soil, for if 

 the manufacturer is fully advised, he can prescribe with reasonable 

 accuracy.
