BRIGHT ON GRAPE CULTURE. 45 



where they decay ) a practice found to be of singular 

 utility to the crops." Again, he says, of vineyards in 

 the island of Madeira, " some growers use animal ma- 

 nures, which others reject, and as the French do, they 

 sow lupines among the vines, and bury them at their 

 roots.'' 



In some of the letters written by Mr. Longworth, of 

 Cincinnati, on the rot in grapes, he states that in seve- 

 ral instances, vineyards which were planted on dry, 

 porous soil, and accidentally mulched xoith loeeds, es- 

 caped the rot, while vineyards in the immediate vicinity, 

 which were kept clean, and not mulched, suffered se- 

 verely. These passages will be found in Mr. Buch- 

 anan's work on the grape. 



We believe that only by shallow planting and good 

 mulching, can we maintain the continued healthfulness 

 of vineyards, while by trenching, heavy manuring, and 

 deep planting, we shall be sure, sooner or later, to in- 

 duce rot and mildew, and the final destruction of the 

 vines.
