out in spring of 1917 for the first time as budded trees, as it 

 would take too many years to work up a stock of the cherry on 

 its own roots. The trees are one year buds on Mahaleb roots. 

 This means that at the North they must be mulched carefully 

 to prevent root-killing. As soon as possible, the Northern native 

 Pin cherry should be tested as a budding stock. Out of a large 

 number of cherries tested at this Station, Moscow is the only one 

 that has borne fruit in satisfactory quantities. The tree is pro- 

 ductive and perfectly hardy. The fruit is of medium size, bright 

 red with light colored juice of good quality. 



I came through St. Paul this fall and went to the fruit mar- 

 ket and got some big, black-juiced California cherries, at 30 cents

a pound. They were certainly very fine. I took them home and 

 compared them with a lot of my sand cherry hybrids spread over 

 two tables in the laboratory. During several days they were 

 tested by many people, and the consensus of opinion was that my 

 black juiced sand cherry hybrids of the Sapa type were just as 

 good. So we have a black- juiced fruit now that will compare 

 favorably with the black-fleshed cherries from California. 



Gooseberries: I began work with the native gooseberry 

 of South Dakota when I first came to South Dakota in Septem- 

 ber, 1895. Since then I have carried the wild gooseberry of the 

 Sioux Valley through six generations by selection. The past sea- 

 son afforded an excellent chance for selecting the best forms for 

 use in raising the seventh generation. The best ones were con- 

 siderable larger than the Houghton. In addition, I have made 

 a number of hybrids of the large European with this South Da- 

 kota gooseberry. Some of these bore the past season and are 

 very promising. They certainly have size, but I do not know 

 whether the white pine rust will spoil all our work with the goose- 

 berries and currants or not. But I do not believe this will be
