warm house, and not watered until small plants appear at 

 the ends of the leaves. 



Cow-pea. See Vigna. 



Cowslip. See Primula and Caltha. 



Crambe. Crucifercs. 



Increased by seeds, by dividing the roots and by root 

 cuttings. See Sea-kale. 



Cranberry ( Vaccinium macrocarpon). Ericacea. 



The cultivated cranberry is propagated entirely by cut- 

 tings. These are made from vigorous young runners, 

 from 6 to lo inches in length, and they are thrust obliquely 

 into the soil until bnly an inch or two of the tip projects. 

 Some blunt instrument, as a stick, is commonly used to 

 force them into the sand of cranberry bogs. Planting is 

 done in the spring, and the cuttings are taken just previ- 

 ous to the operation. If cranberry seedlings are desired, 

 the seeds should be sown in flats of peaty earth, which are 

 stored until spring in some protected place, in the manner 

 of stratification boxes. The seeds should be covered 

 lightly, preferably with fine moss. The plants are allowed 

 to grow the first year in the box. 



Crassula. Crassulacas. 



Seeds ; also by cuttings, which should be taken off and 

 laid for two or three days in the sun to dry before planting. 



Crataegus (Haw, Hawthorn). Rosacea. 



Propagated by stratified seeds, which remain dormant 

 for one or two years. Some growers spread the haws in 

 shallow piles in the fall, and allow them to decay, so that 

 most of the pulp is removed before they are stratified. 

 Haws often come irregularly, even from stratified seeds. 

 The varieties are grafted, rarely budded, on common 

 stocks. 



Cress {Lepidium satiiium). CrucifercE. 



Seeds, sown at any time of year. See Water Cress. 

 Cress, American. See Barbarea. 

 Cress, Keck. See Arabis. 



Crinum. Amaryllidacecs. 



Increased by seeds, sown singly as soon as ripe in three 

 or four-inch pots, in sandy loam and leaf-mold. Place in
