REPOKTS OF EXrKKIMENT STATIONS. 189 



THK NKW SETTINGS. 



We added to our experimental stock in 1906, 111 apples, thirteen kinds; 

 twenty plum trees, five kinds, and two varieties of cherries, three of each. 

 Of the apples we lost none. There are only two of the cherries alive and 

 four of the plums died. I was also presented with two hemlock trees, one 

 of which is living and it looks as though it might continue to do so. 



FIGHT WITH THE WORMS. 



We succeeded in saving only sixty-seven per cent of our apples from 

 the worms in 1906, while in 1905 we saved ninety-five per cent. Space 

 forbids giving a detailed account of our spraying operations. The probable 

 reason for the increase of wormy apples in 1906 over those of 1905 was a 

 failure to supplement the spray with other methods of fighting the pests, 

 such as gathering up the fallen apples and using the disk at the proper 

 time. Another cause for the increase was that the curculio was reinforced 

 largely by the codling moth in 1906, whereas in 1905 there were but very 

 few of the latter insect. Another mistake I think was we only sprayed 

 three times, the last time about the middle of June. We should have added 

 two or three more sprayings at intervals of about fifteen days. 



COXCLUSION. 



In conclusion, I would say that I am adding to my experimental 

 grounds a piece of land at the village of Chambers where the soil contains 

 more clay than is found on the old station. This will give the advantage 

 of testing the question as to what varieties will thrive the best in clay and 

 which are best suited for sandy land. 



All of which is very respectfully submitted, 



J. L. COPPOC, Director. 



SANDOZ EXPERIMENT STATION. 



.JULES A. SANDOZ, HAY SPRINGS. 

 PLUMS FOR THE NORTHWEST. 



This experiment station is situated iu Sheridan county, 4,000 feet 

 above sea, and about 2,000 feet higher than most of the Dakotas. 



The first plums planted here wei'e from Professor Budd, about twenty 

 kinds, and although they were all hardy and came to bearing, the most 

 failed to ripen before the heavy September frosts, De Soto and Wyant 

 ripening only about half the time. I found an early and vigorous wild 

 plum here now sold by nurserymen under the name of Sandoz, which 

 ripens five weeks before De Soto, and which ought to be used also to graft 

 thereon other kinds by northern nurserymen on account of its vigor and 

 hardiness. European plums grafted on it are hardy here, while they 

 winter-kill on usual nursery roots; it is entirely curculio proof. 



About five years ago I sowed seeds of De Soto fertilized by Sandoz and 

 about twenty trees have come to bearing. Out of these five are much 

 superior in tree, size and quality, and earliness than De Soto or Wyant. 



Sandoz No. 1 is an upright grower, plums large, clear yellow, short
