in the year 1863 seedlings were planted in various 

 parts of the country and the report on the subject 

 says that in the temperate lowlands these plants 

 were frost-bitten in the very severe winter of 1879- 

 80, but escaped the danger in the higher altitudes. 

 The plains or lowlands are not on clear, still, and 

 frosty nights, any warmer than higher sites, and, 

 as a matter of fact, are colder than the more 

 exposed positions, as naturally the coldest air finds 

 its way to the lowest point. The Sequoiae grown 

 under home conditions are now about 277 metres 

 in height with a diameter of 95 centimetres one 

 metre above the ground. A high degree of 

 moisture coupled with mild winters such as we 

 get on the North Sea Coast and in the higher 

 parts of the West German Central mountain 

 districts are the primary conditions of success in 

 the cultivation of this timber.

 Red Cedar. 



Experiments on a pretty extensive scale were 

 made with this species of timber throughout 

 Germany and Austria, and for some fifteen years 

 they were very well maintained. Hindrances to 

 their development occurred in the shape of 

 unusually severe late frosts in March and April 

 (see Mayr in his sessional report to the German 

 Dendrological Society in 1901), and also the
