Early Rivers is widely known because of its earliness, productiveness, 

 regularity of bearing and desirability for culinary purposes. In New York, 

 however, the plums are so small and drop so badly as they ripen that the 

 variety is worthless for commercial purposes. Hogg, in the reference given 

 above, notes the following peculiarity of the trees of this variety: " The 

 original tree throws up suckers, which, when removed and planted out, 

 do not bloom for several years ; but scions taken from the original tree and 

 grafted, bloom the second year. A curious fact is that the grafted trees 

 fruit abundantly, and the branches are so brittle they break ofif; in those 

 raised from suckers the branches never break. The grafted trees in spring 

 are full of bloom, sparing of shoots, and very few leaves; the suckers are 

 more vigorous in growth, have no bloom, but an abundance of foliage, 

 even when six years old." This variety is a seedling of Early Tours 

 raised by Thomas Rivers of Sawbridge worth, England, about 1834. It 

 was first disseminated under the names Early Prolific and Rivers' Early 

 No. 2 but, in 1866, Hogg with the permission of the originator, renamed 

 it Early Rivers under which name it is now generally known. 



Tree medium in size and vigor, round-topped, productive; branchlets thick, short, 

 pubescent throughout the season; leaves roundish-oval or obovate, one and three- 

 quarters inches wide, nearly three inches long, leathery; margin crenate or serrate.
