88 BRIGHT ON GRAPE CULTURE. 



perly speaking it is a compound of ammonia and super- 

 phosphate of lime, and tartrate of potash, in a form 

 sufficiently soluble to meet the wants of the grape vine. 

 If required, it will all be available in a single season, 

 but if not taken up bj the vines, it will remain in any 

 good soil for years, until it is taken up by plants, and 

 cannot be washed out by rains, or evaporated by heat. 

 It is ready for use, yet enduring as the earth itself. 

 Being manufactured on a large scale, it can be sold 

 cheaper than it can be made by any single individual 

 purchasing the ingredients in small quantities and work- 

 ing without proper apparatus, even if he possess the re- 

 quisite scientific skill to make the proper combinations. 

 We believe it will be of immense service to grape 

 growers, and save them a vast amount of trouble, ex- 

 pense and disappointment, in their efforts to grow the 

 grape by the use of ordinary manures. 



The Grape Fertilizer may be applied to the vine in 

 pots, in the field or garden, as a top dressing, in the 

 fall, after the vine has ceased growing, in the spring, 

 and during the summer when undergoing the stoning 

 process when the fruit ceases to swell for a time, and in 

 addition to growing a fine crop of grapes, it will perfect 

 the fruit a week or two earlier than if not so fertilized. 



The Grape Fertilizer will be furnished in large and 

 small packages, adapted to the wants of grape growers, 

 and detailed directions will accompany each package as 

 to method of using, quantity per acre, or per vine.
