is present in the soil, it is best to resort to grafted plants, as Manettil 

 is not susceptible to ell-worm. 



The most troublesome of all is trip, as it lodges in the buds and 

 flowers. The damage it does to rose growers amounts to thousands 

 of dollars every year. It is in itself easily destroyed, but owing to its 

 habit of secreting itself, so far nothing has been found which will ex- 

 terminate it, and at the same time not injure the plants. Various in- 

 secticides are recommended to keep them in check, those which appear 

 to give the best satisfaction being paris green diluted in water, fumi- 

 gation with tobacco and red pepper, or the different nicoticides, used 

 either on the heating pipes or on the foliage. Any of them means cer- 

 tain death to the trip if he is caught out of his hiding place. It is 

 therefore necessary to continue to use these two or three times a week 

 if any satisfactory result is expected. 



Summing up the whole rose culture, we find that whenever we do 

 not observe the laws governing a healthy plant growth we invite dis- 

 ease and insects to feast on the roses, and thus curtail our profits. 



Mr. Henderson: I think that is a very good paper, and there is no 

 criticism at all to give on it. 



Question: What proportion and how do you use this lime or lime 

 water? 



Mr. Stauch: About a half bushel to a bench 150 feet long. The 

 bench is about six feet wide. 



Mr. Green: I would like to hear Mr. Stauch tell us more about the 

 ell-worm. I don't know anything about it, and would like to know. 



Mr. Stauch: The ell-worm is a pest which infests the roots of roses. 

 The effect on the plant is that it turns yellow and dies. 



Mr. Dole: We white-washed our benches and have not been bothered 

 with the ell-worm. 



The President: Professor Brunei*, will you tell us something about 

 this ell-worm? 



Professor Bruner: There are aeveral different species of this ell- 

 worm, and they infest the roots of different plants. To tell the truth, 

 however, there is not very much known about these things. We don't 

 know their life history. After they once get well established it is very 

 difficult to get rid of them. It seems that they thrive in dry weather 

 and such conditions as well as any other time, and they grow and 

 multiply very fast. Lime seems to be one of the best things to kill these 

 creatures, and I think that is the best remedy when you have a very 

 severe attack of them in the greenhouse. Wash the benches thoroughly 

 with lime water. 



The President: We have with us this afternoon Mr. Wesley Greene, 

 Secretary of the Iowa Horticultural Society. We would be glad to have 

 a few words from him. 



Mr. Greene: Mr. Chairman, Ladies and Gentlemen, I am very glad
