DELIGHTFUL BERRIES 325 



luscious fruit fully an inch and a half in diameter. 

 The fruit is rather soft and more suitable for 

 home use than for the market. But it is a pro- 

 ductive and delicious berry, well worthy of intro- 

 duction in all milder climates. 



Possibly a series of hybridizing experiments, 

 introducing some northern species of Rubus,, 

 would result in giving the plant hardiness, in 

 which case it should become popular everywhere. 

 Such a line of experiment is well worth under- 

 taking. 



THE CLOUDBERRY 



In marked contrast to the Mayberry in point 

 of habitat and hardiness is the Rubus from the 

 far North that is commonly known as the Cloud- 

 berry, or, in some regions, the bake-apple berry, 

 and known to the botanist as the Rubus chamce- 

 morus, a name given to it more than a century 

 and a half ago by Linnaeus. 



The plant inhabits the peat bogs and similar 

 localities far to the north, even within the Arctic 

 Circle. Like many other arctic species of plants 

 it does not confine its habitat to a single continent 

 but is found in northern Europe and Asia as well 

 as in North America. The same thing is true of 

 arctic species of birds and animals; the obvious 

 explanation being that it is easy to wander 

 from one longitude to another in the regions
