The above is founded on an average of the formulas for red clover, white clover, English 

 hay, and timothy. 



Having never used the above special fertilizers, we cannot speak of their merits from 

 experience, but from what we have been able to learn concerning them, they seem better 

 adapted to any other soil than heavy clays, the latter giving often unsatisfactory results. If 

 they will accomplish what is claimed for them on other soils, it will certainly be of assistance 

 to the farmer to learn the results of careful experiments by others, in determining the quantity 

 and kind of fertilizers suited to different crops, and spare him the trouble of experimenting 

 for himself ; however, in the use of commercial fertilizers of any kind, we favor the applica 

 tion of a liberal supply of barn-yard manure, occasionally, as that is a complete fertilizer, and, 

 hence, contains all the elements of plant-food, and will greatly aid in keeping the land in a 

 high state of fertility, and, at the same time, causing it to yield abundant crops. Special 

 fertilizers will, without doubt, also aid in restoring lands exhausted by excessive cropping. 

 As we have previously stated, we regard barn-yard manure, of the b6st quality, the most 

 desirable general fertilizer that can be used by the farmer, and commercial fertilizers as sup 

 plementary to that; but where the former cannot be obtained in sufficient quantities, as is the 

 case with most of our farms the farm -supply not being adequate to the demand, where the 

 lands are fertilized to the extent that high cultivation and successful farming requires com 

 mercial fertilizers are valuable substitutes. Fertilizers of all kinds should be made very fine, 

 that they may be easily taken up and appropriated by the plants, and their fertility, in a great 

 measure, depends upon the fineness to which they are reduced before being applied. 



In addition to the above formulas for fertilizers, the Mapes Co. of New York have, for 

 sugar-cane or sorgo, one containing from two to three per cent, of ammonia, from ten to
