 Transpliiiitiiiii stock of .Vhies normandica and picea e.xcelsa 

 Tests were carried out two years — 1!)15 to IDli — at 



Silkel)or<^ and X'emmetofte F'nrcsts. The results 

 of these tests are i,nven in jj;reat detail. Spruce: tlie large i)lants resist 

 drought hetter than the medium and these again better than the small- 

 est ; unpruneil stock gives always the largest per cent usable plants 

 hut the longest roots lie bent in the bottom of the hole or ditch. Dif- 

 ferences in survival of the grades is less in a favorable than in a dry 

 season. Light root pruning shows practically no difference in a favor- 

 able season. Init may result in much loss of pruned stock in a dry 

 summer and in poor growth. If the second season is moist the tops 

 develop most and if dry the roots grow proportionately larger. Strong 

 tamping of the soil in transplanting is useless. The third or smallest 

 class of all seedlings should be discarded ; foot pruning makes the 

 work easier; the stock will stand more j)runing ou clay soil than on 

 sandy soil ; for use on the latter site pruning should consist in cutting 

 the long straggling roots only. The results check well for both species.

Twelve experimental plantations have been 

 Tests of Climatic made with oaks from Denmark, Holland, Russia, 

 J'aricties of Oak Moravia. Hungary, Sclavonia. South Austria, and 

 Hanover. These were started in litOlt. The 

 results to date show that none of the introduced varieties can be used 

 with absolute certainty and that tlie oaks of Danish origin are best 

 suited for local use. The oaks fram native seed are more robust and 

 vigorous than those of foreign origin, their manner and time of de- 

 velojmient render them less liable to attack by mildew. The non- 

 native oaks are generally more straight than the Danish variety, they
