Hammer is one of the best native plums. On the Station grounds 

 the trees of this variety make the best orchard plants of any of the native 

 varieties, being large, vigorous, shapely and hardy, falling short onl)- in 

 being a little uncertain in bearing. The fruits are good in quality, hand- 

 some in appearance and keep and ship well, but crack badly in unfavor- 

 able weather and, according to some writers, are quite subject to brown- 

 rot. Hammer extends the season of the Americana plums considerably, 

 for though a hybrid, it may best be ranked mth the Americanas, and is 

 well worth planting in home orchards in New York, where the native plums 

 are too seldom found; in particular, this variety can be recommended for 

 the colder parts of this State where Domestica and Insititia plums are not 



hardv. 



Hammer is one of H. A. Teny's numerous productions and was grown 

 from a seed of the Miner evidentl)- fertilized b)' an Americana. The blood
