have been made to induce the Chinese to make a 

 business of growing it, but that hitherto it has 

 been necessary to depend entirely upon plants 

 growing wild in the mountains. 



The vine clambers over the underbrush on the 

 mountainside like a grapevine. It is, of course, 

 very hardy. 



One of the attractive features of plants of this 

 tribe is the ease with which they may be propa- 

 gated. Not only can they be grown readily from 

 seed, usually producing new varieties, but they 

 grow also from soft or hard wood cuttings, from 

 tip cuttings, or by layering. 



When a new variety is produced of the desired 

 type, it can be multiplied indefinitely by dividing 

 any part of the plant into sections and placing 

 these under conditions suitable for growth. 



Some of the plants of the genus are true climb- 

 ers. Most of them, however, trail upon the ground, 

 usually hugging it closely. Those that climb are 

 valuable for covering screens, arbors, walls, and 

 low buildings. The trailers are valuable for dec- 

 orative purposes and quite often for their fruits. 



In Corea and Manchuria the long, slender vines 

 of Actinidia polygima (the species with which my 

 experiment began) are used for cordage. 



Other species are used in the manufacture of 

 paper.
