"The cypress tribe," said Miss Harson, "differ from the pines, or Coniferae, by not having their fruit in a true cone, but in a roundish head which consists of a small number of scales, sometimes forming a sort of berry. One of the most common of this family is the arbor vitae, or tree of life--a tree so small as to look like a pointed shrub, and more used for fences than for ornament. An arbor-vitae hedge, you know, divides our flower garden from the kitchen-garden and goes all the way down to the brook."
