ground, and take longer time to root. Grape vines are generally 

 propagated by eyes (fig. 109). A plump bud is se- 

 lected with a piece of stem on each side. The eyes

more light. Loddiges recommended that the end of the shoot should 

 be dipped in collodion ; but I have found no advantage from the process. 

 We multiply some plants, as the polyanthus, phlox, and chrysan- 

 themum, by division (fig. no), and others, as the strawberry, by runners

(fig. III). Some plants are multiplied by bulbs, as the hyacinth, 

 amaryllis (fig. 112), shallot, garlic; and others by dividing the tuber, 

 as the potato (fig. 113) and yam. 



All the above cases are multiplications of an individual plant
