Dr. H. von Schrenk exhibited some burls on the white 

 spruce (Picea Canadensis). The burls, unlike most of those 

 so far known, are almost round, and are covered with smooth 

 bark. They grow of various sizes, and occur on the trunk 

 and branches of a group of spruces limited to a small area. 

 The wood fibers are arranged in annual rings ; they differ 

 from normal wood fibers because of their thinner walls and 

 greater internal diameter, giving the wood a spongy character. 

 Long rows of secondary resin passages occur in each ring.
