FILBERT CULTURE. The following 

 are the most esteemed kinds : White 

 Filbert; well known. Red; similar, 

 but having a red skin. Prolific; cob; 

 a very large nut. Cosford; fine flavour, 

 thin shell, great bearer. Prolific dwarf; 

 well adapted for small gardens. Gor- 

 don's thin shelled ; a good nut. Friz- 

 zled ; similar to the other filberts ; 

 husk more ornamental. 



Propagation. Layers, cuttings, graft- 

 ing, and seed. Shoots of the previous 

 year's growth root readily, if layered 

 any time during the rest season. Cnt- 

 tlmjs should be made similar to those 

 of the currant, the lower buds cut out, 

 in order to destroy their propensity to 

 suckering. If they are to form neat 

 little bushes, on a dwarfing system for 

 small gardens, the cuttings may 

 nearly half a yard in length. ( 

 is performed as with the apple or pear, 

 and at the period when the buds first 

 begin to swell. The common hazel- 

 nut, or the Spanish nut, are generally 

 used for stocks ; the latter, it is affirmed, 

 Avill not produce suckers. 



Seed. This practice is resorted to 

 for the sake of raising new varieties, or 

 for producing the ordinary ha/els. In 

 the former case, there is much room 

 for progress still ; and certainly no 

 plant otters greater facilities to the 

 hybridiser. Bearing as it does, male 

 and female blossoms separately, every 

 opportunity exists for depriving any 

 given kind of its catkins betimes. 



Soil. Any ordinary soil, if pretty 

 good, will answer, provided it is not 

 stagnant. A free upland light loam, 

 however, is what they prefer. We have, 

 nevertheless, known them succeed very 

 well in a moorish-looking soil ; and on 

 well-drained peats, which had become 

 sound through the application of marl 

 or clay.
