THE NURSERY LIST. 227 



Muehlenbeckia, Sarcogonum. Polygonacece. 



Seeds. Increased usually by cuttings, taken in early sum- 

 mer in a frame. 



Mulberry (Mortis alba, M. nigra and M. mbra). Urticacece. 



New sorts are grown by seeds, which should be handled 

 in the same manner as small fruit seeds. Named varieties 

 are multiplied by cuttings of the root, or of mature wood, 

 and sometimes by layers. The tree may also be budded or 

 grafted by ordinary methods. 



The common white mulberry was formerly used as a stock 

 for named varieties, but Russian mulberry seedlings are 

 now much used. The stocks may be top-worked out-doors, 

 or root-grafted in the house. They are commonly crown- 

 worked, however, in the house in winter, the stocks being 

 grown in pots or boxes for the purpose. They are then kept 

 under glass until the weather permits them out-doors. By 

 this method fine specimen trees are procured, but they are 

 readily handled by cheaper methods. The weeping and 

 other ornamental sorts are now worked upon the Russian 

 mulberry. 



Mulberry, Paper. See Broussonetia. 



Mullein. See Verbascum. 



Musa (Banana, or Plantain-tree). Stitaminece. 



Seeds may be sown in heat during spring. Suckers are 

 used for those species which produce them. Many of the 

 species do not produce seeds freely, and suckers must be 

 relied upon. See Banana. 



Muscari, including Botryanthus (Grape Hyacinth). Liliacece. 



Increased by seeds, and by bulbels, which are obtained by 

 lifting the old bulbs early in the autumn, about every second 

 year. 



Mushroom (Agaricus campestris]. 



Break up the commercial spawn into pieces about as large 

 as a hen's egg, and plant it in drills or holes, using from one- 

 half pound to a pound of spawn to each square yard of bed. 



The spawn is the mycelium of the fungus held in a mass 

 or ' ' brick " of earth and manure. Various methods are em- 

 ployed for making the spawn, but the essentials of them all 

 are that the body of the brick shall be composed of a porous 

 and light material, which can be compressed into a compact 

 mass ; fresh mycelium must be communicated to this mass, 

 and then a mild heat must be applied, until the whole mass
