A Thorny Climber 



Beside the back fence of Mr. Burbank's garden at Santa 

 Rosa there grow, within a few feet of each other, two black- 

 berries which never fail to excite wonder. One is the typical thorny 

 type shown above; the other is the absolutely smooth thornless 

 blackberry a complete transformation. The u;or- 

 like capacities of the thorny blackberry bramble 

 are familiar to everyone who has ever 

 gathered blackberries.
