HEREDITY AND FORESTRY. 5 



latter case the resultant plants were slightly taller than from the 

 lower altitude. In the same Table the average growth-in-height 

 for the year 1905 is also shown, that is to say, the average length 

 of the last shoot. Fifteen years after sowing the seed the slower 

 growth of plants from seed harvested at a high altitude is still as 

 conspicuous as ever, and it seems probable that this characteristic 

 will be maintained throughout the life of the tree. The poor 

 growth, on the whole, during 1905 is accounted for by the 

 extraordinary intensity of the drought of 1904, which was con- 

 tinued with but little modification throughout 1905.

Austrian Experiments with Spruce {Crop 1890) 

 in the Wienerwald (1650 /<?<?/). 



In the lowest line of the above Table (II.) figures are shown 

 which relate to plants grown from Swedish seed, and it will 

 be seen how very poorly such plants have grown in Central 

 Austria. 



Table III. also deals with Austrian experiments on spruce, the 

 seed in this case being of the crop of 1894. This seed, from 

 three altitudes in Silesia, has produced plants of exactly the same 

 character as the others already discussed. The leading shoot in
