down. The red varieties increase rapidly by means of 

 suclcers whicii spring up from the roots. Better plants 

 are obtained by means of root cuttings, however, as de- 

 scribed under Blackberry (see also Fig. 62). Black-caps 

 may be increased by root cuttings. These cuttings are 

 best handled in warm coldframes or mild hotbeds, being 

 planted very early in spring. By the time the weather is 

 settled, they will be large enough to plant in nursery 

 rows.

 Grown sometimes from seeds, which should be denuded 

 of pulp. Layers of tender branches are sometimes em- 

 ployed. Most commonly grown from cuttings. These 

 are made from tips of growing or ripened shoots, and are 

 2 or 3 inches long, with all the leaves left on. They are 

 usually, from necessity, variously branched. The soft 

 cuttings are usually taken from forced plants, and are 

 handled in a close frame or under a bell-glass, with 

 bottom heat. In commercial establishments the cuttings 

 of ripe wood are preferred. The following is the practice 

 of one of the largest nurseries in the country : Cuttings 

 of the entire season's growth, cut to a heel, are taken in 

 October and November, and are placed in sand in boxes 

 in gentle heat, as in a propagating-house. By February 

 the roots will be formed, ^nd the boxes are then placed 

 in a cool house where the temperature is about 50°. Early 

 in spring (about April ist) the boxes are placed outdoors 

 in coldframes, where they remain until May, until frost is 

 over. The boxes are then removed from the frames and 

 are set on boards in a shady place, where they are left 

 until fall. In the fall — having been nearly a year in the 

 boxes — the plants are shaken out and are heeled-in in a
