THE NEW AGRICULTURE. 113 



ists proves that drouth is accompanied by destructive attacks of 

 insects. How far these depredations might be prevented by irri- 

 gation cannot be predicated, but it is beyond doubt that the vigor 

 of growth that would result from a sufficient supply of moisture to 

 the roots would greatly mitigate the effects of these attacks. The 

 apple trees which never have an off year are those grown near 

 bodies of water. A California vineyardest who irrigated his vines, 

 immediately raised his product to eight tons of grapes per acre, 

 and greatly improved the quality. The newly planted orange 

 groves of Florida are frequently destroyed by drouth, and methods 

 of irrigation are eagerly sought to render their culture more safe 

 and certain. But if it were necessary to enforce the advantages of 

 the irrigation of orchards, abundant evidence could be gathered 

 in the south of France, Italy and other countries of southern Eu- 

 rope, where the olive, orange, lime, almond, fig, apple and other 

 orchard trees, as well as the vineyards, are systematically brought 

 under irrigation. As to the vine, it is a question, so far, which has 

 not been thoroughly investigated, whether or not irrigation might 

 be made the means of vanquishing the destructive phylloxera." 



Possibly our readers may weary with our much quoting from a 

 single author. If other testimony than that of Mr. Stewart were 

 required, the field from which to gather is a wide one, but Mr. 

 Stewart has gleaned facts from all sources and we find in his book 

 the history of the experience of individuals and peoples covering 

 many centuries, hence the invaluable character of his conclusions. 



Among American authors, few, if any, are more popular than E. 

 P. Roe, who writes with a versatility of information and talent 

 upon almost every subject, and upon none with greater acceptance 

 than upon those of agriculture and horticulture. Before us, as we 

 write, lies an elegant volume entitled " Success with Small Fruits." 

 This is an expensive work, and all the more a pity since a book
