except to see that the soil is kept reasonably moist, and at the end of six months 

 roots will have formed, and the plants can be severed from the parent. 



In layering in flats supported by a platform, the operation is the same. The 

 soil should contain plenty of humus, and be watered as often as necessary to keej) 

 it moist. 



By Grafting: This method of propagation has not been extensively practiced 

 but has been found to be successful. So far, the work has been done exclusively 

 under glass. The stock used has been seedling Feijoa, of a diameter slightly less 

 than that of a lead pencil. Both whip-grafting and veneer-grafting have been 

 employed with equal success. The scions should be of about the same diameter as 

 the stock, and the operation should be performed during March and April or

August and September. After the graft has been made, the plants must be kept 

 under bell jars or in a tight glass frame, to exclude the air as far as possible, for 

 a week or more. It is likely that some other myrtaceous shrubs or trees may 

 prove more desirable for stocks than seedling Fcijoas. Dr. Trabut of Algiers 

 suggests Eugenia jambolana, on account of its hardiness and vigor. 



By Inarching: The Feijoa lends itself readily to inarching, but this 

 method is too slow and laborious to permit of its being widely practiced where 

 any other is successful. Layering gives the same results with less labor, and 

 cuttings should be more expeditious than either.
