by side with one of Larix leptolepis. Both plots were in full growth 

 when the severe frost about the end of April occurred and both 

 suffered severely. 



In 1909 they were to be planted out. 



Of the European larch, more than 6o/o were worthless not having 

 been able to recover from the damages caused by the frost. 



But nearly all the Japanese larches were good plants having 

 suffered but little permanent damage. 



If, as this seems to indicate, the Japanese larch can thus throw 

 off the effect of late spring frosts, it should be the better able to 

 withstand the attack of the larch canker (Peziza WUlkommii\

On the estate of Greymeg, Scotland, about 2 acres were planted 

 with a mixture of common larch, Scots fir, and Douglas fir, and 

 other 2 acres with Japanese larch, Scots fir, and Douglas fir. 



Rabbits did enormous damage in the first four or five years, 

 and the plantation has been filled up many times. 



The Japanese larches have quite justified their introduction, for 

 those that the rabbits left are well grown, and at present are en- 

 tirely free from disease, while the European larches are badly at- 

 tacked. 



Judging from this experience, the author is of the opinion that 

 the Japanese larch should be planted here in preference to the 

 European variety, on soil and in situations suited to it.

The author presents evidence to show that Quercus robur and 

 Q. sessiliftora^ instead of being identical as they are usually con- 

 sidered, differ in botanical structure, habitat, and range.
