shoots, from 4 to 6 inches in length, in a sandy place in 

 sprincj or fall. The latter method is the better way in this 

 country, and in the north the cuttings should be handled 

 under glass,

Increased by cuttings of half-ripened shoots in sand 

 under a hand-glass, in moist bottom heat.

Seeds. They may be sown in the open ground in 

 spring, or in the fall and the young plants wintered in a 

 coldframe, or in a hotbed or forcing house in late winter 

 or sprin.g. Brussels sprouts, broccoli and cauliflower are 

 treated in the same manner.

Propagation by seeds is not often adopted, as it is a 

 very slow method. The seeds should be sown in very 

 sandy soil, and placed in a semi-shady position until ger- 

 mination commences, when they may be e.xposed and 

 very carefully watered. Usually propagated by cuttings 

 or offsets, which should be made with a sharp cut, and 

 laid upon a sunny shelf or on dry sand until the wound is 

 healed and roots emitted, when they should be potted 

 in sandy soil. Place in a bench and keep syringed. 

 Some of the less fleshy types may not require this prelimi- 

 nary "curing" or drying. A cereus cutting is shown in 

 Fi,g. 72. (For an elaborate account of the propagation of 

 cacti by cuttings, see Arloing, Ann. des Sci. Nat. 6th Ser. 

 iv. pp. 5 to 61, with plates, 1S76.) Grafting is resorted 

 to with weak kinds, which will not grow freely e.xcept 

 upon the stock of a stronger species ; and by this means, 

 also, such kinds can be kept from the damp soil, which 

 frequently causes decay. The stocks usually emploved 

 are those of Cereus tortuosus, C. Penivianiis, Pereskia 

 aai/eata, etc., according to the species intended for work- 

 ing ; they readily unite with each other. If the cion and
