the operation is then called "mossing" (Fig. 

 68). A paper cone may be used in place of 

 a pot when the atmosphere is not too humid, 

 as in carnation houses (Fig. 69). 



Pot-layering is employed not only for the pur- 

 pose of multiplying plants, but to lower the 

 heads of "leggy" or scraggly specimens. The 

 pot is inserted at the re- 

 quired point on the main 

 stem, and after roots have 

 formed abundantly the top 

 may be cut off and potted 

 independently, the old stump

handy devices for facilitating pot-layering. 

 66 shows a layering-pot, provided with a niche in p^ s tion or other 

 the side to receive the stem, and a flange behind 

 for securing it to a support. The pot shown in Fig. 65 is a 

 similar device. Fig. 70 represents a layering-cone. It is made 

 of zinc or other metal, usually 4 or 5 inches high, and is com- 

 posed of two semi-conical wings, hinged on 

 the back and secured in front, when the in- 

 strument is closed, by means of a hinge-pin. 

 A cord is inserted in one side, with which to 

 hang it on a support. A cup or pot with a 

 removable side is also used. This is shown

 compound layering-pot is shown in Fig. 

 73. The main stem or trunk of the plant 

 is carried through the large opening, and the 

 branches are taken through the smaller pots
