!6o THE NURSERY-BOOK. 



Chervil (Cheer ophy Hum bulbosum and Scandix Cerefolium). Um- 



bellifercc. 



Seeds, sown much the same as celery seeds, but the plants 

 are usually allowed to stand where sown. Seed is often 

 sown in autumn. 

 Chestnut (Castanea sativa and var. Americana, and C. Japon- 



ica). Cupuliferce. 



Chestnut stocks are grown from seeds. Difficulty is some- 

 times experienced in keeping the seeds, as they lose their 

 vitality if dried too hard, and are likely to become mouldy 

 if allowed to remain moist. The surest way is to allow the 

 nuts to become well dried off or " seasoned ." in the fall, and 

 then stratify them in a box with three or four times as much 

 sand as chestnuts, and bury the box a foot or two deep in 

 a warm soil until spring. They do not always keep well if 

 stored or stratified in a cellar. Fall planting exposes the 

 nuts to squirrels and mice. American stocks are probably 

 better than European. 



The stocks are worked by whip-grafting above ground, the 

 wound being well tied and protected by waxed cloth. Care 

 should be taken to have the stock and cion about the same 

 size, in order to secure a good union. Crown-grafting, root- 

 grafting and budding have not been very successful in this 

 country upon the chestnut. The cions should be cut early, 

 before they begin to swell, and kept dormant until the stock 

 begins to push into leaf. Only vigorous stocks should be 

 grafted. The best results are obtained when the stocks have 

 recovered from transplanting, or when they are from three 

 to five years old. The working of chestnut stocks is far from 

 satisfactory in a commercial way. The union is imperfect 

 in many varieties, and usually no more than half the grafts 

 take well. 

 Chicory (Cichorium Intybus}. Composite^. 



Seeds, sown in spring where the plants are to grow. 

 Chilopsis (Desert Willow). Bignoniacece. 



Increased by seeds, or by cuttings of half-ripened shoots 

 in sand under a bell-glass, in a gentle bottom heat. 

 Chimonanthus. Calycanthacece. 



Propagated by layering in the autumn. 

 China Aster. See Callistephus. 

 Chiococca (Snowberry). Rubiacece. 



Propagated by cuttings, which strike root freely in sand 

 under a hand-glass, in heat.
