326 THE FRUIT GARDEN 



not have some enemy of this kind. But science and industry have found means 

 of overcoming them or holding them in check. The rural papers — of which we 

 have more than lOO good ones — the agricultural experimental station bulletins 

 and books on fruit-growing, are replete with directions for combating these 

 evils. Sulphate of copper is the basis of the remedies for fungus diseases, and 

 arsenic for nearly all insect pests. 



FRUIT STORAGE 



While the great range of climate and the numerous varieties of fruits enable 

 the average farmer or inhabitant of the towns and cities to be abundantly 

 supplied with fresh fruit of some kind at moderate cost during the greater part 

 of the year without the aid of cold storage houses, these have helped materially. 

 They were first built about i860, and cooled by means of natural ice, but since 

 the invention of chemical refrigeration cold storage houses have been greatly 

 improved and cheapened. Apples, pears, and grapes are now kept for many 

 months in perfect condition. It is a common practice to keep apples in this 

 way until the next year's crop is ready for market.
