era! cost of production, including the investment and the cost 

 of heating (cheap fuel, etc.), low. 



19. Everything else being the same, except that one of two 

 localities experiences frost, of course the frost-free one is the 

 better, but where both experience frost heating may or may not 

 increase the cost of production, depending entirely on whether 

 the fruit saved by the heating brought in more money on sale 

 than it cost to save it by heating. A place where frost occurs 

 can compete with a frost-free locality if the general cost of pro- 

 duction and the interest (because of cheaper land) is sufficiently 

 lower to more than offset the cost of heating. 



20. Tables are inserted giving the sale price that must be 

 obtained for the fruit in order to obtain different rates o!f inter- 

 est on land of various values with and without heating for 

 various cost of production. These selling prices are high and in 

 most cases higher than the farmers receive, but they are many 

 of them expecting and getting only employment for their 

 families. 



21. A farmer will increase his profits or decrease his losses 

 by heating if the value of the crop before it is picked is more 

 than the complete cost of the heating. Whether the yield is 

 large, small, or nothing, the place must be cared for almost 

 exactly the same, and the cost of heating must include, not only 

 the oil and labor while the heating is being done, but must include 

 the interest and depreciation of the heating equipment. 



22. The more times that killing frosts occur the more ex- 

 pense would be incurred in protecting against them, but the 

 more fruit would be saved, and where frost occurs frequently 

 enough to be at all serious, the number of nights that heating 

 must be resorted to is almost proportional to the amount of fruit 

 that is saved, so that whether it pays or not to heat an orchard 

 is not a function of the frequency of the frosts, Whether one 

 should heat or not is not a function of the amount of money 

 invested in the place unless the heating is to protect the trees. 

 Of course, in determining 1 the profits the land value certainly 

 enters. To increase one's profits or decrease his losses by heat- 

 ing, the sale price of the fruit must be high, the fuel must be 

 :heap, the frosts must not be accompanied by winds, and the 

 heating must be carried out according to the most modern 

 methods with military precision. 



It is very doubtful whether it pays in Utah.
