tween every four trees and wet it and tlien it produced a 

 dense smoke so that the manure has a beneficial eU'ect by 

 forming a cloud of smoke above the orchard retaining the 

 heat that might be there, but there is very little heat that 

 results from the manure pile. It is far better to burn the oil 

 than the manure because the manure it too valuable for the 

 rest of the land. Another thing, a couple of years ago we 

 tried to save something by burning the manure and we had 

 a continual frost and we run out of the stuff when we needed 

 it the most. If a person is equipped with oil it is easy to place 

 it in the pots procured especially for that purpose. 



A Member: How do you store the oil? 



Mr. Mincer: We are preparing at this time to put in a 

 tank holding about 6,000 gallons, and we will haul it from 

 the storage and put it in these tanks until it is used. Now 

 if you have any questions or if there is any phase I haven't 

 touched on if you will ask the questions I will try and answer 

 your questions. 



Prof. Emerson : What weight or type of crude oil do you 

 use? 



Mr. Mincer: It is a type designated by the Standard Oil 

 Company as smudge. It is a grade with the gasoline and 

 lighter oil removed which the gas- companies use. 



Mr. Dickinson : Do you use any waste to start the fire? 



Mr. Mincer: Our orchard has never been equipped with 

 oil heaters, we only had just a few, our only practical ex- 

 perience has been with manure. We have had a few pots 

 around a few trees. 



A Member: About how extensive were your experiments? 



Mr. Mincer: We protected about 12 acres of apples and 

 a good many acres of peaches, probably 20 acres. 



A Member: With oil heaters? 



Mr. Mincer: No, only about 20 trees with oil. Part coal 

 and part oil. We raised the temperature 6 degrees. 



A Member: How many did you have to the acre? 



^rr. Mincer: On 20 trees Ave Imd a heater for everv tree.
