are not sufficiently productive. I do not yet know what is the 

 best combination. 



Plums: The largest of my 10,000 plum seedlings is my 

 Waneta, a 2 inch, 2 ounce plum, which set the fifth successive 

 crop this year, although the trees have been cut back very severely 

 for scions and bud sticks. The Waneta is very strong in nursery, 

 Mr. D. B. Gurney, Yankton, South Dakota, had one grow ten 

 feet from bud in nursery. 



Some years ago I obtained some wild plums {Prunus nigra) 

 collected by Thomas Frankland near Stonewall, Manitoba, and 

 out of many seedlings two were selected and propagated under 

 the names Winnipeg and Assiniboine, as noted in my Bulletin 130. 

 These have been tested at various places at the North, especially 

 in their native region, and have won favor. Here at Brookings 

 the Manitoba plums are characterized by small size of tree, but 

 extremely early season of fruit. In fact, they are the earliest 

 of all the native plums, but are not needed for the main market 

 here, since at Brookings we can raise larger and better plums 

 owing to our later season. 



In the endeavor to improve the fruit in size and quality I 

 have made a number of hybrids of the Manitoba wild plum with 

 choice plums from California. None of these hybrids are as 

 large as Waneta, so it will probably be planted mainly at the 

 North. The trees are productive, and the large red fruit is of 

 excellent quality. The names are all of Indian tribes of the far 

 North, especially Manitoba. 



Ojibwa Plum: Pedigree: Shiro x Manitoba wild plum 

 pollen. Since the Shiro, one of Luther Burbank's plums, is a 

 complex hybrid of four species, the Ojibwa will be a mixture of 

 five different species of Prunus: Nigra, Angustifolia, Cerasifera, 

 Triflora, Simoni. 



Cree Plum : Pedigree : Manitoba wild plum x Combina- 

 tion plum pollen. When introduced in 1901 by Luther Burbank 

 the Combination was considered the best in quality of 25,000 

 seedlings. 



Pembina Plum: Pedigrees: Manitoba wild plum x Red 

 June plum pollen. The Red June is one of the earliest and best 

 plums, imported many years ago from Japan. 



The Ojibwa, Cree and Pembina were introduced in spring 

 of 1917. 



Late Plums for the South : We have raised many seed- 

 lings of the Sand plum of Kansas, Prunus Watsoni. They are
