160 BUSH-FRUITS 



which it was propagated, only the tips from one- 

 year-old plants being used. This variety did much to 

 spread the cultivation of the species throughout the 

 country, and the impetus then gained has steadily in- 

 creased, until the fruit has become one of the most 

 important. Until its immense increase led to a still 

 more rapid increase and consequent destructiveness on 

 the part of injurious insects and fungi,, it was one of 

 the easiest grown and most uniformly successful fruits 

 in cultivation. The development of the evaporating 

 industry has done much to add to its importance, 

 and increase the extent of its cultivation. 



Recently the industry has been seriously threatened 

 by the spread of fungous diseases, notably the anthrac- 

 nose. Further experience, however, seems to promise 

 a feasible plan for keeping it in check, so that the in- 

 dustry need not be crippled.. 



As this is the youngest member of the raspberry 

 family, there is good reason to hope for much improve- 

 ment in it. There is a very marked improvement in 

 the best varieties of the present day over the wild plants 

 of the woods, or those first introduced. This improve- 

 ment seems to be going on rapidly, and there is no rea- 

 son why it should not continue. We want not only 

 better size and better quality than we now have, but we 

 want equally reliable varieties which will come in both 

 early and late.
