QUESTION BOX. 



Q. What do you know about orchard heating? 



Chairman: Some of you who know tell in about two minutes what 

 you know, or tell where they can find out. 



Professor Howard: What I shall tell you is what we have done 

 here on the experimental grounds. We heated two acres last spring and 

 the results were so encouraging that I ordered enough heaters two weeks 

 ago TO heat the remainder of the station orchard. While we were only 

 heating two acres we managed to maintain a temperature inside of the 

 heated area of about four degrees above the outside. We had some 

 four or five thermometers scattered through the heated portion. We 

 maintained that temperature with a type of heater holding about three 

 gallons of oil running at about one-half of its capacity. We would 

 have been able to increase that burning surface about twicJe as much 

 any time of night. I asked the weather bureau the velocity of the wind 

 and was told that night it was some twenty-three miles an hour; we 

 were fighting frost that night, heating an area of two acres with the 

 wind velocity at twenty-three miles an hour and we kept the temperature 

 up four degrees. 



Mr. Williams: Did you save your fruit crop? 



A. We had more fruit than we ever had before; we had several 

 barrels more. 



Mr. Marshall: Was there a noticeable difference between the part 

 heated and the part not heated in the crop? 



A. The particular part that we were heating we call our variety 

 orchard. There were only two trees of each variety in the portion we 

 were heating and I can not answer that question. We had apples 

 outside the heated area. Ben Davis chiefly. We have something like 160 

 to 200 varieties in the variety orchard; some of them would not have 

 borne if there had been more cold weather, on account of the variety. 



Q. What tree would you recommend to plant for wind-breaks in 

 southeastern Nebraska? 



Chairman: I will ask Mr. A. .T. Brown to answer that i)arti('ular 

 question. 



Mr. Brown : I would plant Scotch pine. 



Q. What varieties of apples would you plant in a three-acre orchard 

 near Omaha? 



Chairman: I will ask Mr. Russell to answer that question. 



Mr. Russell: I think I had a friend of mine as!-- that qi!.:atiou and 

 I want some one else to answer it. 



Mr. Williams: Refer that matter to the recommended list of varieties. 



Secretary: For the benefit of the man who asked that question, in the 

 annual report you will find a list of recommended varieties for each 

 fruit district in the state. 



Q. What is the comparative co^st in value of linie-siilphur and home- 

 made mixture and Bordeaux mixture?
