JEFFERS TRIAL STATION IN 1916. 107 



the trees to the ground. One variety is very dark skinned, the 

 other more on the purple order, but both varieties have the 

 genuine markings of the European class of plums. 



Of those varieties originated and sent out by Prof. Hansen, 

 the Watesa, Huya, Tapa, Zekanta and Yuteca, all Americana 

 varieties, all bore good crop. We consider the Yuteca the most 

 valuable variety on account of the large size of the fruit as 

 well as its habit of bearing regularly. Of the Hansen hybrid 

 varieties the Waneta is very promising. On a couple of grafts set 

 in the spring of 1914 we got some plums that for size and 

 quality rank with the finest we have ever grown. 



The Hanska bore freely, but owing no doubt to too much 

 dry weather during late summer, the fruit was undersized and 

 not of as good quality as it had been other seasons. The other 

 apricot crosses, with perhaps the exception of the Yoka, do 

 not seem to be worthy of any further trial. They appear to 

 lack productiveness. 



The Cheresota was very full of fine fruit. Wohanka and 

 Opata gave about one-third of a crop; the other sand cherry 

 hybrids did not produce any fruit to speak of. 



Now a few words about the black fleshed sandcherry hybrids. 

 As a class they seem to lack hardiness. The Sapa holds its own 

 only a year or two and then weakens. The Enopa and Etopa 

 kill back considerably every winter. The Wachampa seems to 

 be the only one of the black fleshed varieties that gives at this 

 station any promise of hardiness. 



Of Theo. Williams hybrid plums the Emerald, Stella and 

 B. A. Q. still hold their record for productiveness and size of 

 fruit. The B. A. Q. is of rather low grade quality. The Emerald 

 however, is in my opinion of the best quality for eating out of 

 hand of any plum we have ever sampled. Terry and Wyant 

 bore full. 



We think spraying our plum trees last spring several 

 times with lime sulphur solution helped us to get our plums 

 sold on the farm at $2.00 per bushel. The sandcherry plums we 

 sold at 10 cents per quart. 



The plum crop was almost a total failure all over this 

 part of Minnesota. The ground is the driest I have ever known 

 it to be at this time of the year.
