The Small Fruits. 159 



9. Antliracnose of the bramble fruits may be held iu 

 check b}'' cutting out and burning infested canes, and plant- 

 ing on new ground. Spraying is but partially successful 

 (227). The orange rust may be controlled by promptly 

 rooting out and burning all infested plants (228). 



10. The raspberry is most important of the bramble 

 fruits (229). 



SUGGESTIONS FOR LABORATORY WORK 



1. Stud}' the growth habit of the bramble fruits, ascer- 

 taining the source of the young shoots and of the fruiting 

 branches, the natural methods of j)ropagatiou of the differ- 

 ent species, etc. 



2. Practice propagating the different species by root 

 cuttings. 



3. Practice planting the young plants with the spade; 

 in the manner illustrated for the strawberry in " Princi- 

 ples of Plant Culture." 



4. Practice "tipping" the ends of the shoots of the 

 blackcap raspberry for propagation. 



Section 2 — The Groselles. 



232. The grcselles include the currants and the goose- 

 berries. These are dwarf, many-stemmed shrubs, bearing 

 flower buds mostly on short spurs from wood two or more 

 years old; the young shoots grow mainly from near the base 

 of the older ones, which are usually more or less recurved. 

 The wood is rather soft, contains a large pith and roots 

 freely from cuttings or layers, by which means the varieties 

 are propagated. The groselles are very resistant to cold, 

 and their cultural range extends over the greater part of 

 the United States and far northward into Canada. The
