varieties. I have grown a few European and native varieties but I have 

 not made a success of it. I have one native variety, the gold plum, and 

 I can not malie it bear. I have five trees I set out in 1897. They have 

 blossomed for two or three crops, blossomed full. I tried to get a speci- 

 men of this plum to bring with me, but I could not even get a specimen. 

 I would like to ask the gentleman if I would set some other varieties near 

 them, if that would fertilize them and make them bear? 



Professor Goff: I think the gold plum should perhaps be set between 

 other trees. We have a few young trees, quite young trees, but they 

 have not had any plums on until this spring. We have but a few of those, 

 but they are growing by the side of or among other varieties. 



Mrs. Davis: We cultivate our plums, and they are set sixteen or 

 eighteen feet apart, and we find that it is too close; we have to be trim- 

 ming them a good deal. Would not mulching harbor insects? 



Professor Goff: I. do not think that it is any more apt to harbor insects 

 than loose soil. 



Mrs. Davis: We have put in our new orchard a few plums and we 

 set these twenty feet each way, and I do not think they will be any too 

 far apart. I do not like the close setting. I would ask if you spray with 

 a prepared mixture for curculio? 



Professor Goff: We do. 



Mrs. Davis: You do not use Paris green? 



Professor Goff: We use Paris green for the last spraying. Paris 

 green is an effective agent in spraying for curculio. I think Professor 



of Illinois, in his experiments, decided that he could reduce the 



number of curculio by spraying with Bordeaux mixture and Paris green. 



Mr. Swaim: I do not want to interrupt the professor's suggestions, 

 while on the plum subject, but I want to give my experience in spraying 

 for curculio with Paris green. I used Paris green early, as soon as the 

 buds started. Whether it was due to climatic conditions, a cold spring, 

 or whether due to the spraying, I don't know; but I do know that I have 

 had but little trouble with curculio this spring, as compared with the 

 year before. 



Professor Goff: I think the cold spring had more to do with it than 

 anything else.
