 collar or summit of the root, and creeping along 

 the surface of the soil ; but producing a new root 

 and leaves at the extremity, and forming a new 

 individual, by the decay of the connecting link.

 Straw- particularly the Strawberry which is a good ex- 

 ample,, and from the root of which a number of 

 creeping shoots are protruded in the course of the 

 summer, extending like the radii of a circle to the 

 distance of eight, ten, or twelve inches or more ; 

 and then striking root towards the extremity and 

 producing a new individual which in the following 

 year becomes wholly separated from the parent, by 

 the decay of the connecting link, and sends out 

 also new runners in its turn.
