BIliailT ON GRAPE CULTURE. 85 



special manures required by the grape are provided in 

 a convenient and perfect form, few persons among the 

 thousands who may read this work, would be able to 

 attain the highest degree of success in grape culture. 



Stable manure, or even slaughter-house manure, alone. 

 v,'ill not grow and perfect the best fruit, nor the best 

 crop, although it may produce immense canes. TV(? 

 advise the use of some stable manure, or other rich 

 manure of like character, or of guano; but we feel as- 

 sured that in really good soil a first rate crop of fine 

 grapes may be produced without any stable manure, 

 guano, or other stimulating manure whatever, by the 

 use of the chemical elements of the grape above des- 

 cribed, which form the ingredients of our fertilizer. 

 Most persons have no doubt noticed that grape vines 

 and fruit trees, in good soil, usually grow, that is in- 

 crease in size, and length of branches, and abundance 

 of foliage, well enough, without stable or other common 

 manure, — but tliei/ don't fruit. Now soap suds, con- 

 taining carbonic acid and potash, applied to an old un- 

 fruitful vine, or tree, will often cause it to fruit abund- 

 antly. The vine may obtain carbonic acid, and ammonia, 

 from the atmosphere, and may grow finely, but if the 

 inorganic or chemical substances required to produce 

 fruit, be exhausted from the soil, they can only be sup- 

 plied by the application of compounds containing them. 



The Grape Fertilizer which we present to the public, 

 is intended chiefly for popular use. The scientific man 

 will of course know what chemical agents to use, in
