SYLVICULTURAL NOTES ON HAZEL. 281 



It retains its germinating power for two years. Of good 

 seed 60 per cent, should germinate. One pound of 

 seed contains about the following number of seeds : 

 small-leaved species = 15,000 ; broad-leaved species 

 = 5,000."" The seed germinates either in the first or 

 second spring. If bedded ifc. sand in the autumn and 

 sown in spring it generally sprouts in the same year. 

 It is easy to transplant, up to a considerable size. 



i. Tending. 



Though Lime is somewhat sensitive against late frosts, 

 the damage caused to it in this way is as a rule mode- 

 rate. Cattle like the leaves. 



There are no other dangers against which the tree 

 requires special protection. Insects and fungi are of 

 little importance. The especial foe to the Lime is the 

 buff -tip moth, Pygcera bucephala, whose gregarious larvse 

 often strip it bare. Other species, as Liparis dispar (not 

 in England) and Biston hirtaria, may do the same. The 

 leaves are sometimes destroyed by a mite, Tetranychus 

 telarius, which occurs in vast numbers and sucks their 

 juices. The cancerous places on the bark may be due 

 to Nectria ditissima.

 a. Utility. 



The Hazel yields a soft moderately heavy wood, 

 which, if young, is very tough, but not durable. Specific 

 gravity, air-dried = -63. The young wood is used for
