 The Honorable Commissioner of Agriculture, Albany. 

 Sir : — The average yield of grapes in western New York in 

 good years is one and three-fourth tons to the acre. This is half 

 or less the yield of the best vineyards. This low average is due 

 to many causes, but one of the chief is the persistent growing of 

 unproductive varieties- The most ready means of correcting this 

 fault is to graft the unprofitable varieties, but growers are, in gen- 

 eral, ignorant of the process. The following account, therefore, 

 drawn from our own experiments, and from the experience of 

 vineyardists in western New York, is prepared for the purpose of 

 supplying this information ; and it is submitted for publication 

 and distribution under section 87, chapter 675, of the laws of 

 1894. L. H. BAII.EY.
