 growth will always be lessened, the life of the plant will 

 be shortened and it will withstand adverse conditions less

241. Pears on apple stocks. A writer in American Gardening 

 claims to have grown Flemish Beauty pears on Wagner apple 

 stocks. The pears were larger and of finer flavor than those on the 

 mother pear tree and were free from brown specks. The grafts 

 bore every year for six years without a break, while the mother 

 tree failed some years and the apple tree bore only biennially. 



Camperdown, a weeping elm, when grafted on European elm 

 (Ulmus scabra) stocks "weeps" from the point of union, the top 

 being more or less flat at first; but when grafted on American elm 

 (U. Americana), it grows upright and very tall, because the vigor 

 of this stock overcomes the weeping habit to a large extent.
