This, is a good mode of grafting

Leaf-blight on the pear, p. 194. 

 There appears to be strong rea- 

 son for believing that the leaf- 

 blight on the pear (as well as 

 the cracking of the fruit,) is •• 

 owing to a parasitic fungus, pro- 

 ducing results similar to rust on 

 wheat. Limited experiments in 

 raising the seedlings on ground 

 never before occupied with pear 

 trees, at a distance of some 

 miles from any pear nursery, 

 and beyond reach of the spread 

 of the fine dusty seed, have 

 been quite successful. 



Training and pruning grapes, 

 p. 393. The accompanying 

 figure (310) exhibits distinctly a 

 vine trained to a trellis, and 

 treated on the renewal system.
