30 FORESTKY WOKK 



November. Oak, Larch, Spruce, Silver Fir, Hawthorn, 



Holly; also Beech and Ash, if late in ripening. 

 December to February. Scots Pine, Corsican Pine, 



Austrian Pine. 

 (These dates apply principally to England. In 



Scotland the seeds are usually from a fortnight to 



a month later in ripening.) 



Except for the more easily collected seed, it is usually 

 cheaper to buy a supply from a good nurseryman. 



Foreign seeds of Larch, Spruce, Corsican, Austrian, 

 and Weymouth Pines, and Spanish Chestnut, to name a 

 few of the more common varieties, are usually superior 

 to home-grown seed. 



Extraction of Seed. 



On very few estates is there a seed-kiln for extracting 

 seeds of conifers, and unless a large quantity of any 

 particular conifer seed, such as Scots Pine, is annually 

 required, the expense of erecting a kiln is not warranted. 

 It is better to send the seed collected at home to a nursery- 

 man to extract and clean. 



When a small quantity of seed from any particular tree 

 is to be extracted, use can be made of an ordinary hot-air 

 incubator. A tray made of laths with wire-netting at the 

 bottom is used to hold the cones. 



The heat required to extract the seeds from the cones 

 of Scots Pine namely, 110 F. or for Larch (105 F.) 

 is easily regulated by anyone who understands an incu- 

 bator.
