220 FORESTRY OF NORWAY. 



a little filled up in the following year on account of 

 damage caused partly by mice and partly by frost, have 

 since then succeeded well, and they show at present on 

 the whole a good, and in some parts even a very good, 

 growth. In the spring of 1870 some maple and a little 

 ash were planted in groups on more exposed places within 

 the same woodland (about ^ maal). A part of this plan- 

 tation has, however, been damaged by frost and by mice, 

 which have gnawed the bark off the trees ; and it does not 

 look so well as the plantation made in 1868 ; within the 

 last two years, however, it has shown a better growth, and 

 it seems to be thriving. In 1871 attempts were made to 

 rear forests by sowing. The upper or easter forest at Aas, 

 on the hill between Frydenhaug and the workmen's lodg- 

 ing house, a piece of about SJ maal, was sowed with fir 

 seed mixed with larch seed. This succeeded well on the 

 whole ; and with the exception of a few spots, where the 

 thick grass had prevented the growth of the small plants, 

 this sowing has at present a good appearance. In the 

 lower or western forest, between the high road and the 

 neighbouring farm, Kvestad, about 1 maal was also sown 

 with fir seed mixed with larch seed; this, however, did not 

 succeed so well, on account of there being here another 

 kind of soil. The sowing of larch seed was a failure, and 

 therefore we find here more bare spots, which will have to 

 be afterwards filled up. Next to this sowing, about 2 maal 

 were experimentally sown in the same spring with oak 

 and ash, the experiment was, however, a failure, the plan- 

 tation, situated on a low level, close to the high road, 

 having since suffered so much from frost that it has had 

 for the greatest part to be cleared and replanted with pine 

 and some Betula oderata ; the replanting, which was com- 

 menced in 1873, and continued in 1875, looks well. All 

 of these experimental plantations in 1868-1871 (all to- 

 gether about 8| maal) were executed exclusively by the 

 pupils of the school, although forest cultivation at that 

 time was not not among the ordinary subjects of teaching 

 which were prescribed.
