IN FROST susceptible districts pro- 

 gressive fruit growers have learned 

 that the best way to protect their or- 

 chards is by kindling numerous small 

 fires or by the use of heaters. 



This method of preventing frost is 

 very efficient, and each year it saves 

 much money for American fruit grow- 

 ers. Just how it has been applied, how 

 many fires are needed to the the acre, 

 and the form and style of burner giving 

 the best results, are well discussed in 

 the Weather Bureau Bulletin No. 1096. 



Many a fruit grower has nursed an 

 expensive orchard to the point of bear- 

 ing only to see his well-deserved reward 

 vanish in a single night. But more and 

 more we are discovering that, if we 

 can not defy certain natural laws, we 

 may still nullify their results through 

 a better understanding of their princi- 

 pals. This is what the up-to-date fruit 

 grower does. He cannot eliminate frost 

 but he can use its principles to protect 

 himself from its effect. 



THE weather bureau bulletin treats 

 the frost prevention methods very 

 thoroughly, and the pamphlet should 

 be particularly useful to anyone who 

 owns an orchard or who contemplates 

 planting one. First of all, the experts 

 point out, the orchard owner should de- 

 termine whether his crop will pay the 

 expense of protection if it will not, 

 then he had better move to a less erratic 

 climate. Certain fruits will stand a 

 lower temperature than others and the 

 experts furnish a temperature chart 

 to show this. 

 Here it is:

Charts which show in a graphic way 

 how the fires should be distributed

 These have been prepared from studies 

 made in successful orchards and are the 

 result of the best method in use in this 

 country. Overhead costs are discussed, 

 as well as the care of the frost-fighting 

 apparatus.

Precautions against pear blister mite 

 should be taken at once. The use of 

 lime-sulphur put on at a strength of 1 

 to 8 or miscible oil, 1 to 17, just as the 

 buds are swelling will give control of 

 this pest.
