A tree, occasionally forty or fifty feet in height, with a trunk rarely two feet in diameter and 
seven to ten feet long, but usually not more than six to twelve inches in diameter, and divided, a short 
distance above the ground, into many irregularly arranged crooked branches forming a loose straggling 
head ; or occasionally, when grown under the most favorable conditions, a shapely tree with a round 
symmetrical head ; or often a shrub with slender stems sometimes only a few inches in height. The 
principal roots with a large thick tap-root descend vertically to a depth sometimes of forty or fifty feet, 
and are supplemented by radiating horizontal roots which spread in all directions and form a dense mat
